Description

FDA has not yet classified the drug into a specified pregnancy category.

Mode of Action

Levodopa is the metabolic precursor of dopamine. Only a small amount of administered Levodopa enters blood-brain barrier unaltered and the remainder is converted peripherally to dopamine by dopa-decarboxylase. Benserazide is a peripheral decarboxylase inhibitor that reduces the peripheral conversion of Levodopa; concurrent admin enables dosage of Levodopa to be reduced and may diminish peripheral side effects such as nausea and vomiting.

Interaction

Increased postural hypotension and possible reduced absorption of Levodopa with TCAs. Reduced effects with phenothiazines, butyrophenones, thioxanthenes and other antipsychotic agents; reserpine, papaverine, phenytoin and isoniazid. Reduced absorption with ferrous sulphate. Pyridoxine (10-25 mg) may reverse antiparkinsonian effect of Levodopa in the absence of concurrent dopa-decarboxylase inhibitor. Exacerbation of abnormal involuntary movements and possibly delayed absorption when used with anticholinergics. Additive hypotensive effects with antihypertensive agents. Increased CNS toxicity with methyldopa. Exacerbation of parkinsonian symptoms with metoclopramide due to its antagonistic effects on dopamine receptor.

Pregnancy Category Note
