Action: How Cilicaine VK works
Phenoxymethylpenicillin produces a bactericidal effect on penicillin sensitive organisms during the stage of active multiplication through inhibition of biosynthesis of cell wall mucopeptides. The antibacterial spectrum of phenoxymethylpenicillin is similar to that of benzyl penicillin, however, it has the advantage of being acid stable and hence better absorbed from the gastrointestinal tract than benzyl penicillin. It is resistant to inactivation by gastric acid.
Phenoxymethylpenicillin as the potassium salt is an active ingredient in both Cilicaine VK 250 mg and 500 mg capsules.
Their inactive ingredients are gelatin, titanium dioxide, iron oxide red, magnesium stearate.
Cilicaine capsules are gluten and lactose free.
