Antiparkinsonian activity of single oral dose of PHNO

Authors


Abstract

PHNO, a new D-2 agonist, was investigated in five patients with Parkinson's disease. In an acute, open, oral, dose-ranging study comparing benefit from single doses, 4 mg of PHNO was found to be equivalent to one tablet of Sinemet 25/250 mg. Adverse reactions were those anticipated for a dopaminomimetic agent. Because of its novel structure and apparent transcutaneous penetration, further studies on PHNO are desirable.
