LEVAMISOLE HCL was originally used as an anthelmintic to treat worm infestations in both humans and animals. Levamisole works as a nicotinic acetylcholine receptor agonist that causes continued stimulation of the parasitic worm muscles, leading to paralysis. In countries that still permit the use of levamisole, the recommended dose for anthelmintic therapy is a single dose, with a repeated dose 7 days later if needed for a severe hookworm infection. Most current commercial preparations are intended for veterinary use as a dewormer in cattle, pigs, and sheep. However, levamisole has also recently gained prominence among aquarists as an effective treatment for Camallanus roundworm infestations in freshwater tropical fish.

LEVONORGESTREL is a synthetic progesterone that is used for emergency contraception. Levonorgestrel is also used alone and in combination with estrogens in conventional oral contraceptives.

MOXIDECTIN is a broad-spectrum antiparasitic active ingredient used in veterinary medicine in pets and livestock against external parasites (lice, mites, etc.) as well as against internal parasites (e.g. roundworms). It is not used against agricultural and household pests.

MORANTEL TARTRATE Morantel is an antiparasitic active ingredient used in veterinary medicine. It is used in horses and livestock against internal parasites (mainly roundworms). It is not used against agricultural and household pests. It belongs to the chemical class of the tetrahydropyrimidines. Morantel is a narrow-spectrum anthelmintic effective against gastrointestinal roundworms but not against those in the lungs or elsewhere in the host's body. It is also effective against certain tapeworms as well. It is ineffective against flukes (e.g. Fasciola hepatica) or external parasites.
