How DROXIDOPA Works

Droxidopa is a synthetic amino acid analog that is metabolized directly into norepinephrine by the enzyme dopa-decarboxylase. This conversion occurs extensively throughout the body, resulting in small and transient rises in plasma norepinephrine levels. The resulting norepinephrine increases blood pressure by inducing vasoconstriction in the peripheral arteries and veins. The drug is believed to exert its therapeutic effects through these norepinephrine levels rather than through the parent molecule itself.

DROXIDOPA Boxed Warning

SUPINE HYPERTENSION WARNING: SUPINE HYPERTENSION See full prescribing information for complete boxed warning. Monitor supine blood pressure prior to and during treatment and more frequently when increasing doses. Elevating the head of the bed lessens the risk of supine hypertension, and blood pressure should be measured in this position. If supine hypertension cannot be managed by elevation of the head of the bed, reduce or discontinue droxidopa [see Warnings and Precautions (5.1) ]....
