What is the primary route of administration for nystatin oral troches?

Nystatin oral troches are specifically designed to be administered orally. The formulation of troches allows for the medication to dissolve in the mouth, providing localized treatment for oral fungal infections, primarily caused by Candida species. When the troche dissolves, nystatin acts directly on the mucosal surfaces of the oral cavity and throat, effectively targeting the infection.

The oral route is particularly advantageous in this context because it allows the medication to come into direct contact with the infected areas, maximizing its antifungal effects while minimizing systemic absorption, which is important given nystatin's mechanism of action and intended use. This administration method differentiates nystatin from other potential routes like intravenous, topical, or intraosseous, which are not suitable for the intended therapeutic effect in this instance.
