Aurora Pharmaceutical announced that it has received Food & Drug Administration approval for its SwineMate (altrenogest) Solution 0.22% (2.2 mg/ml), which is manufactured in Northfield, Minn., in a FDA-licensed facility using the same formulation as MATRIX.

SwineMate (altrenogest) Solution is used for synchronization of estrus in sexually mature gilts that have had at least one estrous cycle. Treatment with altrenogest solution 0.22% results in estrus (standing heat) four to nine days after completion of the 14-day treatment period. Administer 6.8 mL (15 mg altrenogest) per gilt once daily for 14 consecutive days. Treat gilts on an individual basis by top-dressing SwineMate on a portion of each gilt’s daily feed allowance. To produce the desired synchronization of estrus in a group of gilts, treat all the gilts daily for the same 14-day period.
