(+)-Norfenfluramine hydrochloride, a major hepatic metabolite of (+)-fenfluramine, is a selective 5-HT2B receptor agonist (Ki: 11.2 nM). (+)-Norfenfluramine hydrochloride potently stimulates the hydrolysis of inositol phosphates and increases intracellular Ca2+. (+)-Norfenfluramine hydrochloride can be used for the research of primary pulmonary hypertension and valvular heart disease[1].

In Vitro	(+)-Norfenfluramine (1 nM to 100 μM) hydrochloride contracts arteries with a dramatic decrease in threshold (aorta and mesenteric resistance artery) in rats[1]. (+)-Norfenfluramine (1 and 10 μM, 3 min) hydrochloride induces contraction in aorta from tissues of normotensive and hypertensive rats[1]. (+)-Norfenfluramine (0-10 μM, 3 min) hydrochloride induces 5-HT release from rat hippocampal synaptosomes by Ca2+-dependent way [2].
In Vivo	(+)-Norfenfluramine (1-300 μg/kg, i.v.) hydrochloride induces pressor response in conscious SHAM and DOCA-salt rats[1]. (+)-Norfenfluramine (2.5 and 5 mg/kg, i.p.) hydrochloride decreases of 5-HT and 5-HIAA levels in telencephalon and brainstem of rats[3]. Animal Model: Conscious SHAM and DOCA-salt rats[1]. Dosage: 1-300 μg/kg Administration: Intravenous injection (i.v.), given in a cumulative fashion at 6-min intervals. Result: Induced pressor response in conscious SHAM and DOCA-salt rats. (change in mean arterial blood pressure at 300 μg/kg, mm Hg, SHAM vehicle=36, SHAM ketanserin=7, DOCA=51, DOCA ketanserin=19).
