Molnupiravir–Doxycycline–Meloxicam Paste for Feline Gingivostomatitis
Feline chronic gingivostomatitis (FCGS) and juvenile gingivitis are debilitating oral inflammatory syndromes causing severe pain, weight loss, and reduced quality of life. Standard treatment with full-mouth dental extractions achieves remission in only ~60–70% of cases, leaving many cats refractory. A combination paste incorporating an antiviral (molnupiravir), antibiotic (doxycycline), and anti-inflammatory (meloxicam) offers a novel multimodal therapeutic strategy targeting the multifactorial nature of disease.
