Drug Interactions
Levodopa: Decreased levodopa absorption and increased risk of postural hypotension with TCA (e.g. imipramine). Diminished therapeutic effect with concomitant use of antipsychotic agent (e.g. risperidone). Anticholinergic agents (e.g. atropine) decrease the absorption of levodopa and may diminish its therapeutic effect. Concomitant use with antihypertensives may cause postural hypotension. Decreased therapeutic response is observed with papaverine, phenytoin, and isoniazid. Decreased bioavailability with concurrent Fe salt use. Increased parkinsonian symptoms with metoclopramide.
