Clotrimazole is a topical antifungal agent that alters the permeability of the fungal cell wall and inhibits the activity of intracellular enzymes by inhibiting the biosynthesis of ergosterol and other sterols.

It is commonly formulated as a 1 per cent solution flush[1] or 1% clotrimazole gel formulated with hydroxypropyl cellulose, poloxamer or carboxymethylcellulose sodium bases[2].

In canine medicine, clotrimazole is used for treatment of infections with ringworm, Malassezia spp[3] or mycotic rhinitis[4][5].

It has also been used for treatment of urinary infections with Candida spp[6] via intermittent bladder infusions.
