Penicillin V is administered by which route?

Explanation:
Penicillin V is designed for oral therapy because it is stable in stomach acid and has reliable oral absorption, so it can reach therapeutic levels in the bloodstream when taken by mouth. This acid stability is what makes the oral route appropriate for Penicillin V. In contrast, Penicillin G is destroyed by gastric acid and must be given by injection (intravenous or intramuscular) to be effective. Topical forms exist for other purposes, but Penicillin V specifically serves systemic infections when taken orally, thanks to its good oral bioavailability.
