Chorulon is a freeze-dried preparation of chorionic gonadotrophin (human Chorionic Gonadotrophin or hCG) for intramuscular administration after reconstitution. When reconstituted with the accompanying sterile diluent, each 10 mL vial contains 10,000 I.U. chorionic gonadotrophin (equivalent to 10,000 USP Units chorionic gonadotrophin) and 10 mg mannitol, with mono- and disodium phosphate to adjust the pH of the solution.
Finfish: Chorulon is indicated for use as an aid in improving spawning function in male and female brood finfish.
Chorulon should be administered via intramuscular injection just ventral to the dorsal fin for one (1) to three (3) injections. Any single injection should be administered, depending on the fish species, at a dose of 110 to 1122 I.U./kg body weight (bw) for males and 147 to 3995 I.U./kg bw for females.
No withdrawal period is required for brood finfish treated according to label directions. The total dose administered (all injections combined) should not exceed 25,000 I.U. (25 ml) per fish in fish intended for human consumption. (National regulations should be observed).
Chorulon (for fish) is supplied in cartons containing five vials of freeze-dried powder (10,000 I.U. per vial) and five 10 mL vials of sterile diluent.
Store at or below room temperature, 25°C. Keep out of reach of children. Once reconstituted, Chorulon should be used immediately. Unused solution should be disposed of properly and not stored for future use.
Chorionic gonadotrophin has luteinizing hormone-like activity with little or no follicle stimulating or oestrogenic activity.
