Description

Artane is used to treat the stiffness, tremors, spasms, and poor muscle control of Parkinson's disease. It is also used to treat and prevent the same muscular conditions when they are caused by drugs such as chlorpromazine (Thorazine), fluphenazine (Prolixin), perphenazine (Trilafon), haloperidol (Haldol), thiothixene (Navane), and others.

name of Artane is Trihexyphenidyl.

Artane is also known as Trihexyphenidyl, Triphen.

Brand name of Artane is Artane.

Dosage

Paradigms of isometric force control allow study of the generation and release of movement in the absence of complications due to disordered visuomotor coordination. The onset and release of isometric force in Parkinson's disease (PD) was studied, using computerised determinants of latency of response and rate of force generation and release. Components of isometric force control were related to measures of cognitive, affective and clinical motor disability. The effects of treatment were determined by longitudinal study of de novo patients. Patients with PD showed impairment in latency and rate of force change for movement release as well as onset. Rate of force change correlated with depression, clinical motor disability and memory quotient but latency showed no correlation with any of these measures. Treatment improved rate of force release, in concert with clinical motor disability, but not latency. These results suggest dissociations between latency and rate of force change that may be linked to different neurochemical deficits. Further, they demonstrate akinetic deficits in force release that argue against the "neural energy hypothesis" of akinesia.

92 PD outpatients were enrolled in, including 48 males and 44 females, from 43 to 86 years old (mean 65.6 +/- 17.1) with duration of the disease from 0.2 to 27.8 years (mean 4.4 +/- 9.4). The preference of the drug use from the patients were: 40 (43.5%) preferred taking levodopa, 25 (27.2%) with amantadine and/or trihexyphenidyl, 14 (15.2%) with levodopa and others, 4 (4.4%) with dopamine agonist and others, 2 (2.2%) with other drugs, 7 (7.6%) with no treatment. There were 69 (75.0%) patients onset with resting tremor, 15 (16.3%) with bradykinesia, 6 (6.5%) with rigidity, and 2 (2.2%) with unknown symptoms. There was no startically significant difference in anti-PD drugs among the patients onset with different symptoms (P > 0.05). 45 patients appeared the onset of disease before 65 years old and with no dementia, 47 onset after 65 with or without dementia. There was no significant difference of anti-PD drugs between the two groups (P > 0.05). Most patients initiated anti-PD treatment with levodopa but few of them chose dopamine agonist. According to the classification of Hoehn & Yahr, 25(27.2%)belonged to Grade I, 53 (57.6%) to Grade II, 8 (8.7%) to Grade III, 3 (3.3%) to Grade IV and 3 (3.3%) to Grade V. There was no significant differences of anti-PD drugs between different grades of the disease (P > 0.05). 55.3% of the patients changed their anti-PD drugs randomly during the therapy, but with no relation to their gender, age, educational level, dementia, the number of family members, course of diseases, or the degree of Hoehn & Yahr, frequency and categories of medicine.

Two cases of normal dose dependence on Trihexyphenidyl are reported. The literature on anti parkinsonian drug abuse and dependence is briefly reviewed.

artane drug abuse

The investigation of the metabolism of the antiparkinson drugs trihexyphenidyl (1), pridinol (2) and biperiden (3) revealed a graduate tendency for hydroxylation in the different structural elements: If alicyclic, saturated heterocyclic and aromatic ring systems are present in one compound like in 1, the alicyclic ring system is attacked predominately. The amount of metabolites with hydroxy-groups in the saturated heterocyclic ring is much lower, and no hydroxylation takes place in the aromatic ring. In drugs without alicyclic ring systems like 2 the saturated heterocyclus is attacked preferentially, but also some phenolic metabolites are formed. Consequently the following arrangement of falling hydroxylation-tendency can be established: Formula: see text. Probably this arrangement is of common validity and therefore a prediction on the hydroxylation-tendency of other compounds seems to be possible.

The prejunctional muscarine receptor on sympathetic nerves in the rat caudal artery was characterized using several selective antagonists. The inhibitory response of carbachol on vasoconstriction elicited by sympathetic nerve stimulation was antagonized by benzhexol (trihexyphenidyl; pKB 7.1), heptane-1,7-bis(dimethyl-3'-phthalimidopropyl ammonium bromide) (C7/3-phth; pKB 6.5) and hexahydrosiladifenidol (HHSiD; apparent pKB 6.0). These pKB values suggest that the receptor most closely resembles the muscarine M2 receptor subtype rather than the muscarine M1, M3 or M4 receptor subtypes.

Using a complex of physiological methods developed by the author the initial state of bilateral permeability of the capillaries, the supply of tissues with blood through the capillaries, and the character of changes of those parameters in the conditions of the adaptational activity of microcirculation in schizophrenic patients were studied. It has been found that three types of microcirculation disturbances leading to tissue hypoxia can be distinguished in schizophrenia depending on the process type and stage. The types of the capillary permeability disturbances in various forms of the schizophrenic process are described.

Following single or repeated treatment with the irreversible anticholinesterase, DFP or, during infusion of the muscarinic receptor agonist, oxotremorine, and the reversible anticholinesterase physostigmine, effects of challenges with muscarinic antagonists were studied in rats. The antagonists, atropine, scopolamine, benztropine, orphenadrine and trihexyphenidyl induced, to a low degree, limb-shakes (myoclonus) and stereotyped behaviors in normal rats. However, within 24-72 hr after the above pretreatments, this myoclonus was significantly enhanced. The anticholinergic-stereotypies were also increased but only by severe cholinergic pretreatment and at a time later than that for the myoclonus. Myoclonus and stereotypies are known to be produced by treatments which directly enhance serotonergic and dopaminergic activities, respectively. It is suggested that during prolonged cholinergic stimulation, the cholinergic-monoaminergic balance in the brain can be altered depending upon the degree of stimulation. This could be responsible for the observed differential onset of changes in the anticholinergic-behavioral responses, which could, in turn, be mediated by different monoaminergic (serotonin and dopamine) systems.

Our findings demonstrated that the anti-cholinergic agent trihexyphenidyl shows positive effect for a patient population developing deterioration of axial symptoms after STN-DBS. The results in the present study may provide insights into the mechanism of emergence or progression of axial symptoms in patients with PD after STN-DBS.

An 18-year-old woman with paranoid schizophrenia experienced cortical blindness immediately after her first bifrontotemporal ECT treatment. There was complete, spontaneous recovery of vision after 6 hours. Neurological examination, computed tomography of the brain, and electroencephalographic study revealed no abnormality. A combination of circumstances suggested that continuation of ECT was desirable. After clearances from neurological and ophthalmological teams, she received 6 more ECT treatments, starting 9 days after the first.

KW-5338 (domperidone), a new dopamine antagonist, is considered to be an agent to cross the blood-brain barrier with difficulty. The antagonistic activities of KW-5338 against L-DOPA were investigated, KW-5338 showed a strong anti-emetic action against L-DOPA induced emesis in beagle dogs (ED50=0.056 mg/kg (p.o.)) and restored the L-DOPA induced depression of intestinal motility to some extent, while it did not antagonize anti-tremorine activities of L-DOPA and trihexyphenidyl in mice. These results suggest that KW-5338 prevents side effects of L-DOPA such as nausea, vomiting and constipation, without reduction in therapeutic effects of L-DOPA in Parkinson's disease.

The participants were divided into two groups according to their age (0-3 years; 4-18 years) and were evaluated using MD-CRS 0-3 or MD-CRS 4-18 at baseline, i.e., before starting pharmacological treatment (T0), after 6 (T1) and 12 months (T2) of treatment. Univariate repeated measures ANOVA with a Greenhouse-Geisser correction was performed to analyse the scale responsiveness for the three indexes (e.g., Index I, Index II and Global Index) in each group with time (T0, T1 and T2). In addition, Bonferroni test was performed to identify the source of significant differences among means.

A 55-year-old woman with known retinitis pigmentosa for 25 years was progressively clumsy in gait and activities of daily living over the past 30 years. She was able to manage house work and social activities, but she developed swallowing disturbance associated with involuntary neck muscle spasm for 2 weeks, which brought her to our clinic on September 7, 1990. General physical examination was normal except for dry skin. Neurological examination was compatible with sensory-dominant polyneuropathy, showing distal dominant sensory impairment together with absent vibration sense and areflexia in lower limbs, but no gross muscular weakness. There were neck dystonia and bilateral poor visual acuity due to secondary optic atrophy of retinitis pigmentosa. The former responded to the combination of tiapride and trihexyphenidyl. She was admitted twice for further evaluation. Complete blood count and blood chemistry tests including lipids were all within normal limits, and so was cerebrospinal fluid. Pyruvate and lactate before and after exercise loading were also normal. Malignancy workup was negative. To our surprise, serum vitamin E level turned out very low (1.89 micrograms/ml), normal range being 4.7-20.3 micrograms/ml. Oral vitamin E administration test by 2g of alpha-tocopherol showed abnormal absorption curve followed fast clearance in serum. Stool was occasionally positive for fat corpuscles by Sudan III staining, but 99Tc-HSA leakage into the intestines was not detected.(ABSTRACT TRUNCATED AT 250 WORDS)

Trihexyphenidyl (THP) and other antiparkinsonian drugs are known to be substances of abuse. This is true both in abusers of other substances and in chronic schizophrenics, the latter being infrequent abusers of other drugs. Most reports on the abuse of antiparkinsonian drugs among schizophrenic patients warn against the possible harm of this self-medication. The present article describes the different effects of THP on both schizophrenic and non-schizophrenic abusers. The subjective experience in most chronic schizophrenic patients who abuse THP is positive: they claim that THP makes them feel and function better. In the light of these findings, the author suggests that research on the possible benefits of THP in contrast to the potential harm in chronic, residual schizophrenic patients is warranted.

Tiapride is a central dopamine receptor specific antagonist, and it has a benzamide chemical structure. This drug is very useful for the treatment of dyskinesia and such abnormal behaviors as delirium and psychomotor excitation in patients with arteriosclerosis. Most of these patients are elderly and generally suffer from other diseases. Since they are apt to be treated with several drugs for such diseases, the effect of tiapride in combination with various kinds of drugs was examined in rats and mice. Tiapride significantly potentiated the catalepsy-inducing effect of haloperidol and chlorpromazine in rats and tended to potentiate the muscle relaxing effect of diazepam at the highest dose in mice. Conversely, tiapride did not enhance or diminish the hypnotic effect of bromvalerylurea, the anticholinergic activity of trihexyphenidyl, the diuretic effect of bromvalerylurea, the anti-cholinergic activity of trihexyphenidyl, the diuretic effect of trichloromethiazide, or the anti-diabetic effect of glibenclamide. Our findings suggest that tiapride should be used with care in patients taking neuroleptics, but can be used freely in patients on other kinds of drugs.

A reproducible and selective method was developed for the analysis of three anti-pschycotics, i.e. haloperidol, trifluoperazine and trihexyphenidyl in bulk and dosage forms using packed column supercritical fluid chromatography (SFC). The analytes were resolved by elution with supercritical fluid carbon dioxide doped with 16.67% (v/v) methanol containing 0.8% isopropylamine. Parallel studies were performed by HPLC using ion pairing reagent and a comparison is discussed. The method was successfully used for the assay of three formulations containing a combination of: (1) haloperidol-trihexyphenidyl; (2) haloperidol-trifluoperazine; (3) trifluoperazine-trihexyphenidyl.

Rats with the Parkinsonian syndrome induced by administration of acetyl choline and proserine into the rostral part of both caudate nuclei manifest an increased electrical activity (EA) in this part. Tremor, oligokinesia and rigidity are characterized by the appearance of paroxysmal EA with high amplitude of slow and rapid waves. The data obtained allow to conclude that neuropathophysiological basis of the Parkinsonian syndrome is the formation of the generator of pathologically enhanced excitation (GPEE) in the caudate nuclei. Some peculiarities of the GPEE activity in tremor and akinetic rigidity syndromes were observed. Intrarostral administration of dopamine or intraperitoneal administration of cyclodol resulted in the inhibition of GPEE and disappearance of clinical manifestations of Parkinsonian syndrome.

Plasma levels of chlorpromazine (CPZ), 3 of its metabolites and prolactin were measured repeatedly in 18 chronic schizophrenic patients. The patients were studied while on chronic phenothiazine medication (chlorpromazine in 8, other phenothiazines in 10), during 4-6 weeks on placebo and during 6-12 weeks of CPZ treatment. The findings were compared with those obtained during acute CPZ treatment in patients who had received similar CPZ doses but no previous long-term phenothiazine medication. Plasma CPZ levels were similar in the chronic and the acute groups and so was their relation to dose. In neither group was therapeutic effect related to plasma CPZ level. In these chronic patients, in contrast to findings during acute CPZ treatment, neither prolactin level nor the appearance of parkinsonian symptoms was related to plasma drug level. In the chronic group both these effects were less pronounced during the period on CPZ which followed the placebo than were the corresponding effects during CPZ treatment in the acute group. Since plasma CPZ levels of the two groups were similar, these differences may be due to an acquired tolerance of the nervous system to some of the antidopaminergic effects of the drug.

Two cases of Gilles de la Tourette's syndrome occurring in Sri Lanka are reported. Both patients had the characteristics of the syndrome as described by Fernando (1967): (1) Childhood onset (below 16 years of age); (2) Multiple motor tics; (3) Unprovoked vocal utterances which may progress to coprolalia. Both responded to haloperidol, withdrawal of medication being followed by relapse, and reintroduction by remission. The literature on the aetiology of the condition has been reviewed. The weight of evidence favours an organic cause, although psychological precipitation cannot be ruled out.

In order to reveal possible differences between pre- and postsynaptic muscarine receptors, seven antagonists were tested for their affinities on these receptor sites in the rabbit isolated perfused heart. Methacholine was used as an agonist to inhibit the noradrenaline overflow evoked by electrical stimulation (3 Hz, 3 min) of the sympathetic nerves (presynaptic parameter) and to decrease the systolic tension development of the right atrium (postsynaptic parameter). The affinity of an antagonist was expressed as pA2. A decreasing order of potency was obtained with ipratropium, scopolamine, atropine, trihexyphenidyl, amitriptyline, and gallamine, both for pre- and postsynaptic responses. The antagonists acted competitively and their effects were reversible. Furthermore, for none of the drugs did the pA2 (pre) differ from the pA2 (post). With QNB (3-quinuclidinyl benzilate) a pA2 (post) of 11.65 was obtained. However, the affinity to presynaptic receptors could not be determined as a pA2 value due to the very prolonged exposure time required for the equilibrium with QNB and for that with methacholine in the presence of QNB. It is concluded that the antagonists employed do not reveal differences between pre- and postsynaptic muscarine receptors of the rabbit heart, in spite of their greatly varying chemical structure and their individual affinities ranging over 5 orders of magnitude. The findings confirm the view of a homogeneous muscarine receptor population characterized by functional parameters.

Fourteen slightly disabled patients with Parkinsonism were treated separately with benzhexol, amantadine, and levodopa. Benzhexol and amantadine both gave buy artane online a 15% reduction in functional disability and levodopa a 36% reduction. Benzhexol lessened the rigidity and improved the flexion of posture of Parkinson's disease, but had little or no effect on akinesia and tremor. Amantadine and levodopa caused improvement in all these symptoms. The combination of benzhexol and amantadine was as effective after four weeks of treatment as levodopa was after six months.

Malathion-induced marked potentiation of BPMC toxicity (about fivefold) was analyzed by measuring LD50 as an index of acute toxicity. The acute lethality of BPMC was decreased by muscarinic blockers (atropine buy artane online , methylatropine, or trihexyphenidyl) or a monoamine oxidase inhibior (pargyline) and increased by a monoamine depleter (reserpine) or a dopaminergic blocker (haloperidol). The potentiation observed with BPMC and malathion was decreased by the muscarinic blockers, monoamine depleters (reserpine, alpha-methyl-p-tyrosine), an alpha-noradrenergic blocker (phentolamine), or haloperidol. The acute toxicities of other N-methylcarbamates MPMC (3,4-dimethylphenyl N-methylcarbamate), MTMC (3-methylphenyl N-methylcarbamate), NAC (1-naphthyl N-methylcarbamate), and XMC (3,5-dimethylphenyl N-methylcarbamate) were potentiated by malathion to a lesser degree than that of BPMC. Atropine protected against the lethalities of all N-methylcarbamates. Reserpine or haloperidol potentiated the lethalities of N-methylcarbamates with a similar tendency toward malathion. When the inhibitory effect of each N-methylcarbamate on brain acetylcholinesterase (AChE) was compared with its LD50, among five N-methylcarbamates BPMC had particularly strong anti-AChE activity. This characteristic of BPMC was not observed after the treatment with reserpine. These results suggest that BPMC may act not only on cholinergic nerves as an anti-AChE, but also on monoaminergic nerves which antagonize the lethal cholinergic effect. Malathion might inhibit the effect of BPMC on the monoaminergic nerves, thereby markedly potentiating the lethal effect of BPMC.

The PD models were established by buy artane online intraperitoneal injection of MPTP (30 mg/kg). 30 C57BL/6J mice were randomly divided into six groups: control group, PD model group, QXT high dosage group, QXT middle dosage group, QXT low dosage group and trihexyphenidyl hydrochloride group. After 7 days of treatment, the behavior pattern of mice were observed, and striatum were seperated to detect the content of TNF-alpha by ELISA.

Twenty-five percent of 80 consecutive patients who met research criteria for persistent tardive dyskinesia (TD) were found to have an energy peak in the parkinsonian tremor band (3-6 Hz) of the frequency spectrum of their machine-measured resting hand movements in addition to the abnormalities consistent with TD (increased energy in the 0.5-3 Hz frequency spectrum). Twelve of these patients were studied again in double-blind fashion 2 hours after receiving a placebo and again 2 hours after a single 4 mg dose of trihexyphenidyl hydrochloride (HCl). Compared with the placebo condition, the trihexyphenidyl HCl markedly diminished the measured energy in the 4 Hz band and had no effect or slightly decreased the energy at all other points on the frequency spectrum. Simultaneous Abnormal Involuntary Movement Scale ratings revealed no change in the dyskinetic movements between the conditions; there was a significant subjective improvement reported by the patients following the trihexyphenidyl HCl administration. These observations indicate that electromechanical buy artane online devices identify a subpopulation of TD patients who may acutely benefit from anticholinergic treatment.

A review of the literature indicates that the anticholinergic antiparkinson drugs can be abused by some patients to achieve pleasurable effects ranging from a mild euphoria with increased sociability at the lower doses to a toxic anticholinergic psychosis with disorientation and hallucinations at higher doses. Trihexyphenidyl may have a greater potential for buy artane online abuse but there has been no systematic data on this issue. While the abuse of these drugs may not be widespread, it is yet another factor arguing for their judicious use.

Palato-pharyngo-laryngeal myoclonus is well-known clinical criterion characterized by persistent, rapid, repetitive, rhythmic muscle twitch the rate of which ranges 50-200 Hz. It appears in the palate, pharynx, larynx, diaphragma, and the ocular or limb muscles, but the most common combination of the distribution is palate-pharyngo-laryngeal type or only palatal type. In most instances the movement is synchronous, but others show asynchronous myoclonus at different rates. There was a case report in which an electrical stimulation given at the ulnar nerve produced reset of myoclonus indicating that some feedback mechanism has some influence in the generation of pacemaker activity in the brainstem. This myoclonus has been considered to result from interruption of any one fiber system in a olivocerebellorubrotegment-olivary equipotential reverating circuit, so-called Guillain-Mollaret triangle. As etiological factors, cerebrovascular accidents are the most common, but various other causes have been encountered including tumor, trauma, inflammation, multiple sclerosis, electroshock, dialysis encephalopathy, and other degenerative neurological diseases. Analysis of the symptoms is the most important cure of the diagnosis, and this myoclonus is relatively easily differentiated from other involuntary movement, but recently MRI is a very effective examination to detect a lesion in the medulla visualizing the degenerative changes of the lower buy artane online olivary nucleus. Clonazepam, trihexyphenidyl, carbamazepine, 5HTP and caeruletin have been reported as effective agents for this movement.

An operant food-related conditioned reflex was developed in six cats by the "active choice" protocol: short-latency pedal presses were followed by presentation of low-quality reinforcement (bread-meat mix), while long-latency pedal presses were followed by presentation of high-quality reinforcement (meat). Animals differed in terms of their food-procuring strategies, displaying "self-control," "ambivalence," or "impulsivity." Multineuron activity was recorded from the frontal cortex and hippocampus (field CA3). buy artane online Cross-correlation analysis of interneuronal interactions within (local networks) and between (distributed networks) study structures showed that the numbers of interneuronal interactions in both local and distributed networks were maximal in animals with "self-control." On the background of systemic administration of the muscarinic cholinoreceptor blockers scopolamine and trihexyphenidyl, the numbers of interneuronal interactions decreased, while "common source" influences increased. This correlated with impairment of the reproduction of the selected strategy, primarily affecting the animals' self-controlled behavior. These results show that the "self-control" strategy is determined by the organization of local and distributed networks in the frontal cortex and hippocampus.

In membranes of the rat frontal cortex, acetylcholine (ACh) and other cholinergic agonists were found to potentiate the stimulation of adenylyl cyclase activity elicited by corticotropin-releasing hormone (CRH). Oxotremorine-M, carbachol and methacholine were as effective as ACh, whereas oxotremorine and arecoline were much less effective. The facilitating effect of Ach was potently blocked by the M1 antagonists R-trihexyphenidyl, telenzepine and pirenzepine and by the M3 antagonists hexahydro-sila-difenidol and p-fluorohexahydro-sila-difenidol, whereas the M2 and M4 antagonists himbacine, methoctramine, AF-DX 116 and AQ-RA 741 were less potent. The mamba venom toxin MT-1, which binds with high affinity to M1 receptors, was also a potent blocker. The pharmacological profile of the muscarinic potentiation of CRH receptor activity was markedly different from that displayed by the muscarinic inhibition of forskolin-stimulated adenylyl cyclase, which could be detected in the same membrane preparations. Moreover, the intracerebral injection of pertussis toxin impaired the muscarinic inhibition of cyclic AMP formation and reduced the Ach stimulation of [35S]GTPgammaS binding to membrane G proteins but failed to affect the facilitating effect on CRH receptor activity. The latter response was also insensitive to the phospholipase C inhibitor U-73122, the protein kinase inhibitor staurosporine and to the inhibitors of arachidonic acid buy artane online metabolism indomethacin and nordihydroguaiaretic acid. These data demonstrate that in the rat frontal cortex, muscarinic receptors of the M1 subtype potentiate CRH transmission by interacting with pertussis toxin-insensitive G proteins.

The effect of psychoactive agents with different clinical actions: three sedative neuroleptics (trifluoperazine, alimemazine tartrate, chlorpromazine), an anticholinergic agent (trihexyphenidyl hydrochloride), two tricyclic antidepressants (imipramine, desipramine) and lithium carbonate on the rotational correlation frequency (V+) of the spin label 16NS has been comparatively investigated in whole human erythrocytes. V+ was about 40% increased by the three neuroleptics, the anticholinergic agent and the antidepressant molecules at 0.2 mM. By contrast, lithium did not induce any significant change in V+ at the same concentrations. It can be suggested that the increase in "membrane fluidity", observed with a wide variety of drugs, is a non specific effect, unrelated to the psychotropic action, that can buy artane online be ascribed to the amphiphilic properties of the tested drugs.

The armamentarium for clinicians treating patients with generalized dystonia, previously restricted to only a few oral medications that often caused intolerable side effects, has been radically expanded in the past decade with the widespread application of deep brain stimulation (DBS). With DBS, patients who in the past would have been restricted to a life of severe motor disability from a young age can now lead lives with only minimal symptoms. Although DBS should therefore be considered as a treatment option for any patient with severe, medically refractory dystonia, important questions remain about patient selection, including what factors predict which patients will benefit from DBS, and when in the course of disease DBS should be performed. Reports show that patients with primary dystonia respond better than those with Crestor Generic Cost secondary dystonia, and limb and axial muscles may improve more than cranial dystonia. Some studies also suggest that shorter duration of disease may be associated with better outcomes. However, it is important to note that even among those thought to respond best to DBS, i.e. patients with primary generalized dystonia, there is a subset that will have significant and sustained clinical benefit with oral medications. It is therefore important that adequate trials of oral medications be attempted prior to referral for surgery. On the other hand, once it is clear that medical therapies are not providing significant benefit or are not well tolerated, children with disabling generalized primary dystonia should be referred quickly for DBS. The dramatic clinical improvement that can be seen with DBS can restore normal or near-normal functioning and avoid the physical and emotional costs of an extended period of decreased physical and social functioning. In general, a levodopa trial should always be considered as the first treatment at the time of presentation of any patient with childhood-onset limb dystonia, in order to exclude dopa-responsive dystonia. Once a diagnosis of primary generalized dystonia is established, we typically initiate treatment with trihexyphenidyl, titrating slowly up to a high dose. We then frequently add baclofen as a second agent. If clinical improvement at that point is inadequate and the dystonia is causing significant functional impairment, we then consider referral for DBS.

In view of the coincidence of antiviral and antiparkinsonism activities of amantadine Nizoral Brand four antiparkinsonism drugs, NorakinR (triperiden), ParkopanR (trihexyphenidyl), AntiparkinR (diethylbenzhydramine) and AkinetonR (biperiden) were tested for antiviral activity in various virus-cell systems. Norakin inhibited the replication of influenza A viruses in chick embryo fibroblast, MDCK and Ehrlich ascites tumour cells. It also inhibited the replication of measles virus in Vero cells, 50% inhibitory concentrations being 2-6 micrograms/ml. The drugs were also active against influenza B virus. Several representatives of other virus families, e.g. vaccinia, vesicular stomatitis, polio type 1 and herpes simplex type 1 viruses were insensitive to the compounds.

We report a right-handed 78-year-old man with early onset parkinsonism. The patient had an onset of micrographia at 23 years of the age in 1939. Seven years later he started to drag his right foot, and at 38 years of age, he walked with small steps with festination. Tremor was also present in his right hand. His daily life was independent as a otorhinolaryngologist. He visited our clinic on March 24, 1977 when he was mentally sound and showed mild parkinsonism consisting of masked face, stooped posture, small step gait, bradykinesia, and right side dominant rigidity and tremor. He showed good response to trihexyphenidyl and amantadine HCl. Two month later, he developed dyskinesia and some worsening of parkinsonism, and was admitted to our hospital for the first time. He was treated with 400 to 600 mg/day of levodopa/ carbidopa. He showed marked improvement, however, dyskinesia remained in his mouth. He was doing well until 77 years of age (June of 1993) when he developed hallucination and motor fluctuations. He was admitted again to our hospital on June 22, 1993. On admission, he was alert and appeared mentally sound. However, Hasegawa dementia scale was 18/30. Upward gaze was slightly restricted (3/5). Voice was somewhat small but no masking was noted. His posture was stooped and the gait was of small step. Dyskinesia was noted during walk. No rigidity nor tremor was noted. Deep tendon reflexes were lost but no sensory loss or motor weakness was noted. Routine laboratory studies were unremarkable. A cranial CT scan revealed only mild to moderate cortical atrophy. Motor and sensory conduction velocities were within normal limits, however, motor action potentials could not be obtained with stimulation to the right common peroneal nerve. He was treated with 600 mg/day of levodopa with carbidopa, 100 mg of amantadine HCl, 300 mg of Dops, and 25 mg of tiapride. He continued to show motor fluctuations, and was discharged on July 23, 1993. Since then his motor functions had become progressively worse with frequent falls, but he was still able to walk without support. On October 3 of 1994, he went to bed as usual. On the next morning, he was found dead in his bed at 9: 30. The patient was discussed in neurological CPC, and the chief discussant arrived Accutane Generic Price at the conclusion that the patient had young-onset Parkinson's disease with Lewy bodies in the substantia nigra. Opinions were divided between Parkinson's disease and Lewy body negative young onset parkinsonism. Postmortem examination revealed obstruction of the trachea by aspirated foods, and the cause of death appeared to have been suffocation by the foods. Macroscopically, the external appearance of the brain was unremarkable except for slight frontal atrophy. The substantia nigra showed depigmentation in the lateral part, but the pigmentation of the medial part was well preserved. Upon histologic examination, the number of pigmented neurons in the dorsomedial part was well preserved. In the lateral part, pigmented neurons were well preserved in the dorsal area, however, in the ventral area, only non-pigmented neurons were seen; they appeared to be neurons in the pars reticulata. No gliosis was seen in any of the nigral areas. No Lewy bodies were seen in the remaining neurons. So-called immature neurons with rounded shape without neuromelanin could not be detected. The locus coeruleus neurons were well preserved. The putamen and the other basal ganglia structures were also intact. Slight myelin pallor was noted in the subcortical white matter, however, otherwise cerebral cortices were normal. The histology of this patient is unique in that only the ventrolateral part of the substantia nigra showed abnormal finding consisting of lack of pigmented neurons without gliosis. It is not clear whether the nigral change represents degeneration or a congenital "hypoplasia'. To our knowledge, such a unique pathology of the substantia nigra has not been reported in the literature. Our patient ma

The ability of acetylcholine muscarinic agonists, injected subcutaneously (s.c.) to elicit yawning and analgesia (tail-flick response) in rats was examined. Yawning was elicited by physostigmine, RS86 and pilocarpine with an inverted 'U'-shaped dose-response relationship; maximal effects occurred at 0.1, 0.5 and 2.0 mg/kg respectively. Neostigmine (0.05-0.2 mg/kg); arecoline (0.5-2.0 mg/kg); bethanecol (0. Flomax Dosage Forms 1-10 mg/kg) and McN-A-343 (5-20 mg/kg) had marginal or no activity. In contrast, dose-related analgesia was obtained following oxotremorine (0.01-0.3 mg/kg) and arecoline (0.5-4.0 mg/kg) and physostigmine (0.1-0.4 mg/kg), RS86 (0.25-2.5 mg/kg) and pilocarpine (0.5-8.0 mg/kg). The effects of acetylcholine antagonists on physostigmine-induced yawning and physostigmine-induced analgesia were also investigated. Following their s.c. injection, trihexyphenidyl, atropine, dicyclomine, secoverine and methylatropine but not pirenzepine, inhibited both yawning and analgesia; there were clear differences in their potencies on the two responses. Pirenzepine, intracerebroventricularly (i.c.v.), inhibited yawning (ED50 value 5.7 micrograms/rat) but not analgesia (3-100 micrograms/rat). The results are discussed in terms of a possible functional differentiation of central muscarinic receptors.

Groups of patients with Parkinson's disease, either medicated, or unmedicated and early in the course, together with age- and IQ-matched Levitra Buy control subjects were tested in two paradigms measuring different aspects of selective attention. The first set of tests compared visual discrimination learning following intra- and extra-dimensional shifts, using a "total change" design in which each shift was made in the presence of novel exemplars of the compound stimuli used as discriminanda. The second test consisted of a visual search task in which the number of alternatives was varied. The results of the first experiment showed a selective deficit in both groups of Parkinsonian subjects in their ability to perform an extra-dimensional shift. In the visual search task, the patients were less accurate, but responded with equivalent choice reaction times to those of controls. The results are discussed in terms of the nature of the attentional dysfunction that occurs in Parkinson's disease.

The neuroleptic malignant syndrome (NMS) commonly occurs on treatment with neuroleptics, it is also reported in patients who suddenly stop drugs like levodopa, amitriptyline and imipramine. We report a case of NMS, which occurred in a patient on lithium, haloperidol and trihexyphenidyl (THP) after sudden discontinuation of THP. The cholinergic system, through its effect on the dopaminergic system, may play a role in the genesis of NMS. Alternatively, anticholinergic withdrawal may produce extrapyramidal symptoms (EPS), and the consequent alteration in food and fluid intake may produce electrolyte imbalance which increases the risk for NMS.

In a study of acquired equivalence in Parkinson disease (PD), in which patients were tested on normal dopaminergic medication, we found that comorbid clinical depression impairs initial acquisition, whereas the use of anticholinergic therapy impairs subsequent transfer generalization. In addition, this study provides a replication of the basic finding of Myers et al (2003) that patients with PD on dopaminergic therapy are impaired at initial acquisition, but normal at subsequent transfer generalization, generalizing these results to an Arabic-speaking population including many participants with no formal education. These results are consistent with our past computational modeling, which argues that acquisition of incrementally acquired, feedback-based learning tasks is dependent on cortico-striatal circuits, whereas transfer generalization is dependent on medial temporal (MT) structures. They are also consistent with prior computational modeling, and with empiric work in humans and animals, suggesting that anticholinergic drugs may particularly impair cognitive abilities that depend on the MT lobe.

An 8-year-old girl received 53 grays radiotherapy after surgery for craniopharyngioma. One year later she developed generalized dystonia. Computed tomography showed bilateral basal ganglia calcifications, especially of the lenticular nuclei. Pharmacological treatment with tetrabenazine, clonazepam and trihexiphenydile allowed a very limited improvement of dystonia; the course was complicated by dystonic storms and decompensations resulting from the iatrogenous panhypopituitarism.
