์์ฉ ๊ธฐ์ : Isoxsuprine acts as a **beta-adrenergic agonist** (specifically **beta-2 receptors**), though its vasodilatory effects may also stem from direct smooth muscle relaxation independent of beta-receptors. * **Vasodilation**: Stimulates **beta-2 receptors** โ increases intracellular **cAMP** โ decreases intracellular calcium โ **vascular smooth muscle relaxation** (primarily in skeletal muscle). * **Uterine Relaxation**: Relaxes uterine smooth muscle, acting as a tocolytic agent. * **Hemorrheologic Effects**: At high doses, it can decrease blood viscosity and reduce platelet aggregation. * **Cardiac Effects**: May exhibit positive inotropic and chronotropic effects on the heart via **beta-1 receptor** stimulation. * **Analgesia**: Does not appear to possess significant analgesic properties in horses.

- Treatment of orthopedic conditions, such as navicular disease (For long break-over if therapeutic shoeing does not correct) ยท 1.2 mg/kg PO q8h for 3 weeks. The dose is decreased as soundness improves, to 1.2 mg/kg PO once daily for 6 weeks, then every other day until heel first landing occurs. ยท PO ยท q8h initially ยท 3 weeks initially, then tapered ยท Phenylbutazone is added if lameness is greater than grade II on a scale of I-V, or until recheck occurs. The drug is classified as a 'blocking' agent by the AHSA.
- Treatment of orthopedic conditions, such as navicular disease (To increase the circulation to the podotrochlea) ยท 0.6-1.2 mg/kg twice daily until sound, then decreased to once daily for 2 weeks then further decreased to every other day. ยท PO ยท twice daily initially ยท Until sound, then tapered

Serious toxicity is unlikely in horses after an inadvertent oral overdose due to poor bioavailability. * **Clinical Signs**: CNS stimulation (uneasiness, hyperexcitability, nose-rubbing), sweating, hypotension, tachycardia, and GI disturbances. * **Treatment**: Provide supportive care. Treat CNS hyperexcitability with **diazepam**, and hypotension with **intravenous fluids**.
