Successful Treatment of a Chronic Facial Abscess Using a Prolonged Release Antibiotic Copolymer in a Golden Lion Tamarin (Leontopithecus rosalia)

Advances in Therapeutics and Delayed Drug Release

Reducing the frequency of drug administration in the treatment of exotic pets is advantageous because it may decrease handling frequency and thus potential stress and injury risk for the animal, increase owner compliance with the prescribed treatment, and decrease need for general anesthesia in patients that cannot be handled safely. Increasing efficient drug plasma concentration using sustained-released delivery systems is an appealing solution. Potential candidates that could provide a promising solution have been investigated in exotic pets. In this article, the technologies that are the closest to being integrated in exotic pet medicine are reviewed: osmotic pumps, nanoparticles, and hydrogels.

TREATMENT OF MYCOTIC RHINOSINUSITIS IN A BENNETT'S WALLABY ( MACROPUS RUFOGRISEUS) USING TOPICAL VORICONAZOLE SUSPENDED IN A REVERSE THERMODYNAMIC PLURONIC GEL

An approximately 4-yr-old female Bennett's wallaby ( Macropus rufogriseus) was evaluated for chronic left-sided facial swelling and nasal discharge. Computed tomography, endoscopy, biopsy, mycologic culture, and panfungal polymerase chain reaction were consistent with destructive mycotic rhinosinusitis. The patient's infection was treated with a long-term injectable antibiotic, oral antifungal therapy, and multiple intranasal infusions of voriconazole suspended in a reverse thermodynamic pluronic gel. This case represents the first documented case of mycotic rhinosinusitis in a macropod and underlines the importance of advanced cross-sectional imaging in the diagnosis, monitoring, and management of nasal cavity disease in zoo animals.
