In a double-blind study the efficacy and tolerability of tizanidine was compared with those of carbamazepine in the management of trigeminal neuralgia. Six patients were allocated to treatment with tizanidine and six to carbamazepine. After individual titration the maximum daily doses were 18 mg and 900 mg, respectively. Among the efficacy factors used, the(More)
To investigate whether the novel, potent and highly selective 5-hydroxytryptamine3 (5-HT3) receptor antagonist ICS 205-930 can prevent migraine attacks, we conducted simultaneously two randomized, double-blind, placebo-controlled, multicentre, international trials, involving a total of 204 patients, suffering from classic or common migraine. Both trials had(More)
The effect of stimulation of cerebral dopamine D-1 receptors by CY 208-243 on motor disability was tested in MPTP-treated parkinsonian marmosets and patients with Parkinson's disease. CY 208-243 (0.5-1.25 mg/kg s.c.) produced a dose-related reversal of akinesia and rigidity in the marmosets, lasting some 2 h. Single morning doses of CY 208-243 (5-40 mg)(More)
CQA 206-291, a new ergot derivative with a "biphasic" dopaminergic profile, was studied in 6 patients with longstanding Parkinson's disease suffering from pronounced fluctuations in hourly mobility. On alternate days, up to seven single doses, escalating from 0.2 to 20 mg, were given as replacement for the usual first morning dose of levodopa. At the most(More)
The selective 5HT3 antagonist tropisetron was studied in 91 outpatients meeting DSM-III criteria for Generalized Anxiety Disorder. Following a placebo washout period of up to 1 week, one of three active treatments (tropisetron 0.5 mg, 5 mg, or 25 mg daily) or placebo was given for a further 3 weeks. After 7 days treatment termination rates due to inefficacy(More)
A selective dopamine D1-receptor agonist, CY 208-243, was administered to 23 de novo patients who had had Parkinson disease (PD) for less than or equal to 3 months. The drug was first used as monotherapy and then in some patients in combination with a dopamine D2-receptor agonist, bromocriptine. Results showed that CY 208-243 exerted a mild antiparkinsonian(More)
We found blood pressure (BP), heart rate (HR), plasma norepinephrine (NE), and epinephrine (E) levels in the lying and the standing positions to be similar in never-treated parkinsonian patients (stages 1 and 2) and age-matched controls. CY 208-243, a new centrally active D1 agonist, significantly decreased BP, HR, and NE (but not E) values in the lying(More)
The therapeutic profile of a new antispastic drug cannot be defined solely on the basis of placebo-controlled studies. Its potential advantages must be evaluated in comparison with existing drugs. This review compares the efficacy and tolerability of tizanidine, a newer muscle relaxant, with that of baclofen and diazepam, the most widely used antispastic(More)
Calcium-related mechanisms are an integral part of metabolic reactions during acute cerebral infarction. In an animal model of stroke, the calcium antagonist isradipine was shown to protect neurons against ischaemia. In order to improve the neurological and functional outcome of human stroke patients, a randomised, double-blind, placebo-controlled(More)
The aim of this study was to evaluate the effect on the activity of the hypothalamic-pituitary dopaminergic system of two new atypical antipsychotic drugs: the ergoline derivative SDZ HDC-912, which is a dopamine (DA) D2 receptor partial agonist; and the quinolinone derivative OPC-4392, which acts as an agonist at presynaptic DA autoreceptors and as an(More)
