Randomized Controlled Trial Comparative Study Clinical TrialPhenobarbitone, phenytoin, carbamazepine, or sodium valproate for newly diagnosed adult epilepsy: a randomised comparative monotherapy trial.
Recent studies have shown that most newly diagnosed epileptic patients can be satisfactorily treated with a single antiepileptic drug. We therefore undertook a prospective randomised pragmatic trial of the comparative efficacy and toxicity of four major antiepileptic drugs, utilised as monotherapy in newly diagnosed epileptic patients. Between 1981 and 1987 243 adult patients aged 16 years or over, newly referred to two district general hospitals with a minimum of two previously untreated tonic-clonic or partial with or without secondary generalised seizures were randomly allocated to treatment with phenobarbitone, phenytoin, carbamazepine, or sodium valproate. ⋯ The overall incidence of unacceptable side effects, necessitating withdrawal of the randomised drug, was 10%. For the individual drugs phenobarbitone (22%) was more likely to be withdrawn than phenytoin (3%), carbamazepine (11%), and sodium valproate (5%). In patients with newly diagnosed tonic-clonic or partial with or without secondary generalised seizures, the choice of drug will be more influenced by considerations of toxicity and costs.
