Lomexin is an antifungal medication used to treat skin infections. It belongs to the imidazole class of compounds that inhibit ergosterol synthesis in fungal cells. The drug is absorbed through the skin and penetrates the infected tissue to reach the target organisms. By blocking the enzyme lanosterol 14a-demethylase, Lomexin disrupts the production of ergosterol, a key component of fungal cell membranes. The loss of ergosterol leads to membrane instability, impaired fungal growth, and eventual cell death. The pharmacodynamic effect results from the concentration of the compound at the infection site, where it continues to inhibit sterol synthesis over several days. This selective inhibition spares human cells because they rely on cholesterol rather than ergosterol for membrane structure.

Lomexin is an antiparasitic medication used to treat infections caused by certain intestinal worms. It belongs to the class of benzimidazole anthelmintics that interfere with the parasite's cellular processes. The drug inhibits the enzyme beta-tubulin polymerization, which is essential for maintaining the worm's microtubule structure. This inhibition prevents the formation of microtubules needed for cell division and motility. As a result, the parasites lose motility and are expelled from the host's gastrointestinal tract. Lomexin also disrupts the parasite's ability to absorb glucose, leading to energy depletion. The combined effect of microtubule disruption and metabolic blockage results in the death of the target organisms. Because the mechanism targets structures and enzymes unique to helminths, the drug has minimal impact on human cells.

Lomexin is an oral medication that may cause gastrointestinal upset such as nausea or abdominal discomfort. It can also lead to dizziness or headache in some users. Skin reactions like rash or itching are possible. In rare cases, liver function tests may show temporary changes. Photosensitivity to sunlight might be observed. Routine blood tests can be used to assess any unexpected changes.

Lomexin may cause mild skin irritation or itching at the application site. Some users report temporary dryness or peeling of the treated skin. Headache and mild gastrointestinal discomfort have been observed in a small number of cases. Dizziness or light-headedness can occur but is usually short lived. Rarely, visual disturbances such as blurred vision have been documented. Allergic reactions like rash or hives may develop in sensitive individuals. Most side effects resolve without intervention once treatment ends.
