Regumate (Altrenogest)

REGU-MATE (altrenogest) Oral Solution for Horses 2.2 mg altrenogest per mL (0.22%) is indicated to suppress estrus in mares. Suppression of estrus allows for a predictable occurrence of estrus following drug withdrawal with ovarian follicles 20 mm or greater. This facilitates the attainment of regular cyclicity during the transition from winter anestrus to the physiological breeding season. Suppression of estrus will also facilitate management of prolonged estrus conditions. Suppression of estrus may be used to facilitate scheduled breeding during the physiological breeding season.
