🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Isoxsuprine is a beta-2 adrenergic receptor agonist that also has some alpha-adrenergic blocking activity. It relaxes vascular smooth muscle by stimulating beta-2 receptors, leading to vasodilation and increased blood flow to peripheral tissues. Additionally, it relaxes uterine smooth muscle, which is why it was historically used to suppress preterm labor. The sustained-release formulation provides a gradual release of the medicine over time, helping to maintain more stable blood levels.
