Enhancing mebendazole’s bioavailability

Mebendazole and other drugs in the same class (benzimidazoles) have extremely poor water solubility, resulting in very low absorption by the body (bioavailability). In animal (preclinicaltesting a drug, a procedure, or another medical treatment in isolated cells or in animals; preclinical evidence is considered only an initial indication of possible effects in people) studies, a special formulation dramatically improved the accumulation of mebendazole in tumors.1Studenovský M, Rumlerová A et al.
