Description

Broad-spectrum anti-parasite medication, traditionally used against worms (except tapeworms), but more recently approved for the topical treatment of head lice infestations in patients 6 months of age and older. It is mainly used in humans in the treatment of onchocerciasis, but is also effective against other worm infestations (such as strongyloidiasis, ascariasis, trichuriasis and enterobiasis).

Indication

For the treatment of intestinal (i.e., nondisseminated) strongyloidiasis due to the nematode parasite Strongyloides stercoralis. Also for the treatment of onchocerciasis (river blindness) due to the nematode parasite Onchocerca volvulus. Can be used to treat scabies caused by Sarcoptes scabiei.

Pharmacology

Ivermectin is a semisynthetic, anthelminitic agent. It is an avermectin which a group of pentacyclic sixteen-membered lactone (i.e. a macrocyclic lactone disaccharide) derived from the soil bacterium Streptomyces avermitilis. Avermectins are potent anti-parasitic agents. Ivermectin is the most common avermectin. It is a broad spectrum antiparasitic drug for oral administration. It is sometimes used to treat human onchocerciasis (river blindness). It is the mixture of 22,23-dihydro-avermectin B1a (at least 90%) and 22,23-dihydro-avermectin B1b (less than 10%).

Toxicity

LD₅₀ = 29.5 mg/kg (Mouse, oral). LD₅₀ = 10 mg/kg (Rat, oral). Adverse effects include muscle or joint pain, dizziness, fever, headache, skin rash, fast heartbeat.

Affected Organisms

Parasitic nematodes and other roundworms

Head lice

Biotransformation

Primarily hepatic. Ivermectin and/or its metabolites are excreted almost exclusively in the feces over an estimated 12 days, with less than 1 % of the administered dose excreted in the urine.

Absorption

Moderately well absorbed. Improved absorption with high fat meal.

Half Life

16 hours (also reported at 22-28 hours)

Protein Binding

93%

Elimination

Ivermectin is metabolized in the liver, and ivermectin and/or its metabolites are excreted almost exclusively in the feces over an estimated 12 days, with less than 1% of the administered dose excreted in the urine.
