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)
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 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)
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)
Overdose of carbamazepine (CBZ) can be fatal. We report the case of a patient with near-lethal toxicity due to delayed absorption of drug. A 36-year-old woman was admitted with coma, hypotension, and unusual movements. Carbamazepine (CBZ) level several hours later was 36 mg/L. Gastric lavage revealed no pill fragments, and activated charcoal was(More)
A few neonates born to mothers receiving anticonvulsant drugs during pregnancy have shown defects in vitamin K dependent clotting factors with or without clinical bleeding. Experimentally, phenytoin (diphenyl hydantoin, DPH) has induced clotting defects in cats and inhibited production of clotting factors in rat liver slices. Phenobarbital has produced(More)
