How does Stromectol work in Poland? Stromectol is a drug used for treating various types of parasitic infestations. In Poland and other countries, it is primarily used in the treatment of diseases caused by worms, such as human hookworm, and other parasites. The active ingredient in the medication, ivermectin, belongs to the avermectin group and works by paralyzing and killing parasites through increased permeability of the parasite nerve and muscle cell membranes to chloride ions. This mechanism results in their death due to the selective action of ivermectin on certain receptor types within parasitic cells, making it a highly effective drug. Eliminate parasites with Stromectol for safe and effective treatment.
