Nystatin is available in which forms?

Nystatin is available in which forms?

• A. Topical, oral suspension (swish & spit/swallow)
• B. Intravenous only
• C. Inhaled inhaler
• D. Transdermal patch

Answer: (A)

Nystatin works best when it contacts the surfaces it treats, so it is used as local formulations rather than systems to reach the bloodstream. Therefore, the common forms are topical preparations for skin and mucous membranes, and an oral suspension that is used as a swish-and-spit or swallow to coat the mouth and throat. This local action is why there isn’t a standard intravenous, inhaled, or transdermal form for routine use. Intravenous administration isn’t typical for nystatin because it’s not well absorbed and can cause toxicity if given systemically. An inhaled inhaler or a transdermal patch isn’t part of nystatin’s usual delivery methods either, since the drug’s activity and formulation are designed for local contact in the mouth, throat, or on skin. So the best description is topical forms plus an oral suspension for mucosal candidiasis. (Note: vaginal forms can exist, but they aren’t among the options presented.)
