Tablet, Oral, as hydrochloride:
Generic: 10 mg, 20 mg
Isoxsuprine increases muscle blood flow, but skin blood flow is usually unaffected. Rather than increasing muscle blood flow by beta-receptor stimulation, isoxsuprine probably has a direct action on vascular smooth muscle. The generally accepted mechanism of action of isoxsuprine on the uterus is beta-adrenergic stimulation (Kaindl 1959; Samuels 1959).
Rapid and complete (Samuels 1959)
Urine (Kaindl 1959).

Concerns related to adverse effects:
• Rash: Severe rash has been reported; discontinue use if rash appears.
Isoxsuprine crosses the placenta. Adverse effects (eg, hypocalcemia, hypoglycemia, hypotension, and ileus) requiring treatment have been observed in infants born to mothers who received isoxsuprine during pregnancy. Maternal and fetal tachycardia have occurred with use and pulmonary edema has been reported with maternal use of beta stimulants (Brazy 1979; Brazy 1981). Although isoxsuprine has been evaluated for the treatment of preterm labor, use for this indication is not currently recommended (ACOG 171 2016).
