Adjunctive medication in the maintenance treatment of schizophrenia and its conceptual implications

Abstract

Beyond the continuing use of neuroleptic medication, psychopharmacological treatment approaches during the maintenance phase of schizophrenia often involve adjunctive medication. Appropriate use of such 'polypharmacy' can be crucial to patients in achieving their optimal levels of symptom management and functional capacity, although the risks of side-effects and medication interactions must be weighed. This paper reviews the use of adjunctive anti-Parkinsonian medication, benzodiazepines, propranolol, antidepressants, lithium, and carbamazepine in this context. It also explores a strategy of identifying secondary syndromes in the longitudinal course of schizophrenia which can be approached psychopharmacologically.
