Natamycin

Pharmacological properties

natamycin is a broad-spectrum polyene antibiotic that is active against pathogenic fungi, including yeast and especially candida albicans, which are most often the cause of genital tract infection. acts fungicidal, binding sterols of cell membranes, violates their integrity, causing the death of microorganisms.

The drug does not exhibit sensitizing activity. There were no cases of allergy to natamycin during treatment or during its industrial production and no development of resistance to it was noted.

Thanks to the enteric-soluble membrane, the tablet acts only in the intestine.

The drug quickly and effectively acts when infected with vaginal yeast fungi (candidiasis). Vaginal suppositories have a therapeutic effect also in the presence of vaginal discharge, inflammation and itching, including the upper, less accessible sections of the vagina. The drug quickly melts into the vagina, forming a foamy mass, which contributes to a uniform and complete distribution of the active substance over its entire surface.

Pharmacokinetics When taken orally in the form of tablets, natamycin is practically not absorbed in the digestive tract.

Current methods could not detect natamycin, used intravaginally, and its derivatives in the blood and biological fluids of the body, which indicates the absence of a systemic effect of the drug.

Natamycin is active when applied topically and is not absorbed through the skin and membranes of the mucous membranes.

Indications

Application

Tablets. for the treatment of intestinal candidiasis, adults are prescribed 1 tablet 4 times a day. usually therapy lasts 1 week.

Children aged 3 years and over are prescribed 1 tablet 2 times a day. Due to the pharmacodynamic and pharmacokinetic properties of natamycin, the same dose is recommended for children of all ages. Typically, the duration of treatment is 1 week.

Suppositories. Used in adult women, 1 suppository for 3-6 days. Suppositories are recommended to be inserted as deep as possible into the vagina (in the supine position) once a day (at night).
