Posaconazole is an azole drug similar in action to ketoconazole.

It is primarily used against severe fungal infections such as Blastomyces spp[1].

It is also available in a topical ointment containing mometasone furoate (Posatex®)[2], useful against fungal organisms such as Malassezia pachydermatis[3].

Side-effects such as phospholipidosis in neurons has been reported following use of posaconazole, without evidence for functional neurologic effects[4].

Recommended dose rate in dogs is 2.5 - 3.75 mg/kg given orally every 12 hours.
