Baclofen is a centrally acting muscle relaxant used for treatment of spasticity. Some patients, to experience adequate symptomatic relief, require dosages of baclofen that significantly exceed the conventional 80 mg daily maximum advocated by the 1992 Physicians' Desk Reference. In this pilot study of baclofen kinetics and dynamics in eleven patients, the(More)
Several interactions involving antiepileptic drugs are based on changes in the rate of their metabolism and elimination, with concomitant rise or fall of plasma levels. Thus, phenobarbital generally induces the production of the DPH metabolizing enzyme, but its presence inhibits the action of that enzyme. The net result depends upon the balance between(More)
Seventeen patients with advanced Parkinson's disease who had fluctuations in motor performance while taking standard Sinemet (STD) 25/100 underwent daylong pharmacokinetic and clinical observation studies while taking both STD and Sinemet CR, a new controlled-release formulation containing 50 mg carbidopa and 200 mg levodopa. During treatment with Sinemet(More)
The slow potassium channel blocker 3,4-diaminopyridine (DAP) enhances acetylcholine release from the nerve terminal and improves conduction in unmyelinated nerve. In this open label pilot study, we examined the effect of DAP combined with inpatient rehabilitation in seven patients with motor weakness due to amyotrophic lateral sclerosis (ALS). A single(More)
We placed a 60-year-old man with Parkinson's disease and marked therapeutic response fluctuations on a continuous enteral infusion of levodopa. On around-the-clock infusion, motor performance declined, although the infusion rate was progressively increased. We therefore interrupted the infusion each night. The patient could then progressively reduce(More)
The kindling of amygldaloid and cortical seizures in cats was used to study the prophylactic effects of phenobarbital, phenytoin, ethosuximide, acetazolamide, and dexamethason. Phenobarbital prevented the evolution of such seizures beyond stage 4 in all amygdaloid-kindling animals during 160 days of study. The prophylactic effect persisted on periodic(More)
