One commercial form of Deslorelin Acetate is marketed by Peptech with the brand name Ovuplant. Another form is available in the USA, Sucromate Equine, which was FDA-approved for use in horses in November 2010. This is manufactured by Thorne BioScience LLC and was introduced to the USA market following the withdrawal of Ovuplant. The Deslorelin products are currently approved for use in veterinary medicine and to promote ovulation in mares as part of the artificial insemination process. It is also used to stabilize high-risk pregnancies, mainly of livestock. Unlike other GnRH agonists, which are mainly used to inhibit luteinizing hormone and follicle-stimulating hormone by their ultimate downregulation of the pituitary gland, Deslorelin is primarily used for the initial flare effect upon the pituitary, and its associated surge of LH secretion. Suprelorin is a slowly releasing deslorelin implant used for chemical castration of dogs and ferrets. It is marketed by Virbac. Deslorelin is also used to treat benign prostate hyperplasia in dogs.
Buserelin is a similar GnRH agonist used in humans.
Deslorelin is a synthetic analogue of a naturally occurring luteinising-hormone releasing hormone (LHRH). Bioavailability is almost complete.
Ovuplant was withdrawn from the US market following issues with mares which did not become pregnant failing to return to estrus in a timely manner. Techniques were developed where the implant was removed 48 hours after implantation in the mare, however compounded biorelease Deslorelin products were at the time available as well as more commonly used ovulation promoters such as hCG, which did not produce the same failure effect. Upon "Sucromate Equine" receiving FDA-approval, the compounded products were no longer legally available within the USA, however they remain available in Australia and New Zealand where an approved version is marketed.
As of August 2011 this drug was not approved for general use outside the FDA-licensed functions in the US, other than within approved clinical trials. Orphan drug status has been designated in the US, though approval had not been issued as of 2011.
