VORIF Tablets 200mg - Antifungal Medication for Effective Treatment
VORIF TABLETS (Voriconazole tablets)
VORIF, containing Voriconazole, demonstrates potent antifungal activity by inhibiting fungal cytochrome P-450 enzymes crucial for ergosterol biosynthesis.
Indicated for invasive aspergillosis, esophageal candidiasis, candidemia, and serious fungal infections, VORIF addresses a spectrum of fungal challenges in both adults and children.
The dosage regimen, including a loading dose for the first 24 hours, ensures rapid achievement of therapeutic plasma concentrations. Subsequent maintenance doses vary based on patient weight.
While generally well-tolerated, users should be mindful of potential adverse reactions, including hypokalemia, visual changes, and, rarely, serious events like pancreatitis or Stevens-Johnson syndrome.
VORIF is contraindicated in cases of hypersensitivity to voriconazole components and when co administered with specific drugs like rifampin, ritonavir, and carbamazepine due to potential interactions
