Notes: Isoxsuprine-d6 is intended for use as an internal standard for the quantification of isoxsuprine (Item No. 20688) by GC- or LC-MS. Isoxsuprine is an adrenergic receptor modulator that has α-adrenergic receptor (α-AR) antagonist and β-AR agonist properties.{48236,48237} 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).{48237,32760} Isoxsuprine has antinociceptive effects in an acetic acid writhing test in mice.{32759} It also inhibits oxytocin-induced contractions in isolated rat uterus (IC50 = 9.15 µM).{48238} 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.
