Isoxsuprine is an adrenergic receptor modulator that has α-adrenergic receptor (α-AR) antagonist and β-AR agonist properties. It induces vasodilation of isolated equine common digital artery strips precontracted with norepinephrine, indicating an α-AR effect, and induces relaxation of isolated fowl cecum, an effect that can be blocked by the β-AR antagonist propranolol (Item Nos. 23349 | 17291). Isoxsuprine has antinociceptive effects in an acetic acid writhing test in mice. It also inhibits oxytocin-induced contractions in isolated rat uterus (IC50 = 9.15 μM). It delays labor onset in rats by 31.63 hours when administered at a dose of 10 mg/kg per day on days 13 to 21 of gestation but increases heart rate with increasing concentration.

As a vasilodator drug, Isoxsuprine Hydrochloride is used in veterinary medicine for the treatment of navicular syndrome and laminitis in horses. Isoxsuprine Hydrochloride has been shown to be a β-adrenoreceptor antagonist with β-adrenoreceptor agonistic properties, with both characteristics contributing to vasodilation and uterine relaxation. Studies suggest that Isoxsuprine Hydrochloride may be useful as a as a tocolytic agent in the treatment of preterm labour.
