Doramectin (Dectomax) is a veterinary drug approved by the Food and Drug Administration (FDA) for the treatment of parasites such as gastrointestinal roundworms, lungworms, eyeworms, grubs, sucking lice and mange mites in cattle.[1]

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. Its spectrum includes: Haemonchus spp., Ostertagia spp., Trichostrongylus spp., Cooperia spp., Oesophagostomum spp., Dictyocaulus viviparus, Dermatobia hominis, Boophilus microplus, Psoroptes bovis, among many other internal and external parasites. It is available in 2 dosage forms: 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[2]) in an 1% Doramectin Long Acting Injectable Solution for cattle, sheep, swine[3] 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[3] as an oral flavored bioadhesive gel under the name Doraquest L.A. Oral Gel.[4] It can be used to control and treat internal parasites as roundworms, lungworms and some external parasites.
