List of Anthelmintics (antihelminthics) - Drugs.com.
Most anthelmintics generally have a wide margin of safety, considerable activity against immature (larval) and mature stages of helminths, and a broad spectrum of activity. Nonetheless, the usefulness of any anthelmintic is limited by the intrinsic efficacy of the drug itself, its mechanism of action, its pharmacokinetic properties, characteristics of the host animal (eg, operation of the.
Anthelmintics are a type of medicine that kills helminths. Helminths are worm-like parasites such as flukes, roundworms, and tapeworms. It is important that anthelmintics are selectively toxic to the parasite and not the host. Some work by inhibiting metabolic processes that are vital to the parasite but absent or not vital in the host. Other anthelmintics are poorly absorbed through the gut.
Anthelmintic effect of papain on Heligmosomoides bakeri. Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms ( helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. They may also be called vermifuges (those that stun.
Anthelmintics must be selectively toxic to the parasite. This is usually achieved either by inhibiting metabolic processes that are vital to the parasite but not vital to or absent in the host, or by inherent pharmacokinetic properties of the compound that cause the parasite to be exposed to higher concentrations of the anthelmintic than are the host cells.
Quinacrine, an early synthetic antimalarial later superseded, is often used as an anthelmintic for the treatment of tapeworm infection in dogs, cattle, and other animals. Nematode anthelmintics. Treatment of roundworms is complicated by the fact that some live in blood, lymphatics, and other tissues (filarial worms) and thus require use of drugs that are absorbed from the intestinal tract and.

Anthelmintics are medications used to eradicate parasitic worms (helminthes) from the human body. Helminth infections are one of the most common infections, affecting a large proportion of the world’s population, mainly in tropical regions. In developing countries they pose a large threat to public health, and leading to malnutrition, anaemia, eosinophilia (a higher than normal level of the.
Anthelmintic definition, of or relating to a substance capable of destroying or eliminating parasitic worms, especially human intestinal helminths. See more.
Anthelmintic resistance is widely documented in cyathostomin parasites, and all equine establishments should be expected to have at least some level of resistance to one or more drug classes. In the absence of resistance, adult cyathostomins were susceptible to several anthelmintics belonging to four chemical families, and two anthelmintic regimens demonstrate activity against encysted larvae.
Together, these anthelmintics represent the current arsenal available against parasitic worm infections. In the UK, farmers rely most heavily on the first three classes, but resistance to these drugs is now widespread. Share this: Twitter; Facebook; Like this: Like Loading. Leave a Reply Cancel reply.
