It is used for the treatment and control of internal parasitosis (gastrointestinal and pulmonary nematodes), ticks and mange (and other ectoparasites). Doramectin is a derivative of ivermectin. Similarly to other drugs of this family, it is produced by fermentation by selected strains of Streptomyces avermitilis.[2] Its spectrum includes: Haemonchus, Ostertagia, Trichostrongylus, Cooperia, and Oesophagostomum species and Dictyocaulus viviparus, Dermatobia hominis, Boophilus microplus, and Psoroptes bovis, among many other internal and external parasites. It is available as an injection and as a 5-mg/ml topical solution.

Doramectin is also marketed in many Latin-American and some Asia and Africa countries as Doramec L.A. (manufactured by Agrovet Market Animal Health[3]) in a 1% Doramectin Long Acting Injectable Solution for cattle, sheep, swine[4] and others. Its oleous carrier confers to Doramec L.A. a slow and prolonged liberation, extending its action up to 42 days.

Doramectin is also available for horses[4] as an oral, flavored, bioadhesive gel under the name Doraquest L.A. Oral Gel.[5] It can be used to control and treat internal parasites as roundworms, lungworms and some external parasites.
