Treatment of many diseases caused by helminths is impossible without the use of special drugs that have a detrimental effect on parasites. The mechanism of action of these drugs may differ. Some of them paralyze the helminth, others disrupt its metabolic processes, and others increase the permeability of cell membranes. One of the drugs with anthelmintic action is Levamisole. It is often prescribed for the treatment of the most common parasitic diseases. Our article contains instructions for the use of Levamisole.

Levamisole is an almost white, rounded tablet. The surface of the tablets is flat, has a notch and beveled edges. Each of them contains 50 mg of the active ingredient, which is levamisole hydrochloride.

As additional ingredients in the preparation used:

  • sodium starch;
  • talc;
  • magnesium stearate;
  • silicon colloidal dioxide;
  • regular starch;
  • lactose;
  • calcium hydrogen phosphate.

The drug belongs to the group of anthelmintic and immunomodulatory agents used to treat nematodes. Levamisole is a derivative of imidazothiazoles.

The drug has a detrimental effect on helminths due to a violation of the energy metabolism of parasites, inhibition of the processes of fumarate recovery, blockade of succinate dehydrogenase. The active substance contributes to the depolarization of cell membranes in the muscles of the parasites. After the helminths are paralyzed, they are excreted from the body in a natural way during the day due to intestinal peristalsis.

The immunomodulatory effect of the drug is due to the following:
