Based on a review of this drug by the National Academy of Sciences-National Research and/or other information, the FDA has classified the indications as follows:
Possibly Effective:
Final classification of the less-than-effective indications requires further investigation.
Vasodilan (isoxsuprine HCl tablets, USP) 10 mg and 20 mg. These tablets contain the following inactive ingredients: acacia, dibasic calcium phosphate, lactose, magnesium stearate, starch (corn), and talc.
Oral: 10 to 20 mg, three or four times daily.
There are no known contraindications to oral use when administered in recommended doses. Vasodilan should not be given immediately postpartum or in the presence of arterial bleeding.
On rare occasion oral administration of the drug has been associated in time with the occurrence of hypotension, tachycardia, chest pain, nausea, vomiting, dizziness, abdominal distress, and severe rash. If rash appears, the drug should be discontinued.
Although available evidence suggests a temporal association of these reactions with isoxsuprine, a causal relationship can be neither confirmed nor refuted.
β-Adrenergic receptor stimulants such as isoxsuprine hydrochloride have been used to inhibit pre-term labor. Maternal and fetal tachycardia may occur under such use. Hypocalcemia, hypoglycemia, hypotension and ileus have been reported to occur in infants whose mothers received isoxsuprine. Pulmonary edema has been reported in mothers treated with β-stimulants. Vasodilan (isoxsuprine HCl tablets, USP) is neither approved nor recommended for use in the treatment of premature labor.
