Ceva has been marketing Altresyn® (altrenogest), an oral solution for suppressing estrus in mares to help facilitate the scheduling of breeding. Altresyn, the only FDA-approved generic to Regu-Mate®(altrenogest), has been on the market since the fall of 2012.
Altrysen is proven to effectively suppress estrus in 95 percent of mares after 3 days of treatment. Mares exhibiting regular estrous cycles return to estrus within 4 to 5 days following treatment and continue to cycle normally.
Use Altrysen for:
Breeding management - enhance your ability to schedule breeding
Performance mares - suppressing estrus may reduce undesirable changes in temperament.
Altresyn is contraindicated for use in mares with a previous or current history of uterine inflammation. Talk to your veterinarian about the proper use and safe handling of Altresyn. Avoid skin contact and always wear protective gloves when administering. Pregnant women, or women who suspect they are pregnant, should not handle Altresyn.
