Research Interests:

Current antiviral therapy for the human herpes viruses, HSV–1, –2, and varicella zoster virus and the feline herpesvirus, FHV-1, consists of multiple doses of FDA-approved anti-herpetic drugs (typically acyclovir [ACV], valacyclovir, penciclovir [PCV], or famciclovir) taken daily for the lifetime of the host. These daily doses require rigorous patient compliance; missed doses allow small windows of drug troughs that permit breakout replication, sometimes resulting in drug-resistant mutants. Our research involves slow, controlled release of ACV or PCV from both biodegradable and non-biodegradable polymer matrices. These devices release continuous, steady levels of drug for an estimated 3 to 5 years after a single implantation. We are continuing to explore the chemistry, biology, pharmacology, and engineering of these implants to further improve their design and eventual clinical deployment in human and veterinary patients.
