Nystatin
Nystatin (abbreviated NYS)[1], original name fungicidine, is a polyene antifungal medication for topical use.
Application[edit | edit source]
Nystatin is a fungistatic to fungicidal antifungal medicine that inhibits the growth of the genus Candida, Rhodotorula, Torulopsis and Trichosporon and micromycetes of the genus Aspergillus. It is suitable for the treatment of superficial candidiasis of the skin and mucous membranes, including the intestinal mucosa (when administered orally), oral candidiasis and vaginal candidiasis. In topical and oral administration, it is not absorbed into the systemic circulation; and because of that, it can also be used during pregnancy. Not suitable for the treatment of endomycosis.
Mechanism of action[edit | edit source]
Like other polyene antifungals, nystatin acts by binding to ergosterol. Ergosterol is one of the basic components of the plasmatic membrane of microscopic fungi. The binding of the antifungal medicine causes the formation of pores in the membrane through which potassium ions escape from the cell. This ultimately leads to death of the cell. Ergosterol is found only in microscopic fungi and protozoa, mammalian cells do not contain it; nystatin is therefore relatively non-toxic to humans.[1]
Agents[edit | edit source]
Nystatin-containing agents are available in both HVLP and IPLP forms. HVLP products available in our country include ointments (eg Fungicidin, Drugs from ZENTIVA) and vaginal globules (in combination with other products); Agents in the form of oral suspensions, gels and tablets (eg Mycostatin) are also produced abroad.
History[edit | edit source]
Nystatin was discovered by bacteriologist Elizabeth Hazen and chemist Rachel Brown in 1950, who isolated it from Streptomyces noursei cultures. The original name fungicidine was later changed to nystatin by New York State in the Health Department Laboratory where the discovery took place.[2]
