Propicillin (Baycillin Mega) is this semisynthetic penicillin, analogous to penicillin V, was introduced in the early 1960s. Although it is better absorbed from the gastrointestinal tract, overall it is inferior to phenoxymethylpenicillin and phenoxyethylpenicillin because of its lower antibacterial activity. Propicillin is used by propicillin-susceptible pathogens in adults and adolescents from 14 years to treat mild to moderate bacterial infections. These include skin infections, ear, nose and throat infections (such as otitis media, sinusitis, tonsillitis, pharyngitis) and infections of the bronchi andlung inflammation. Moreover propicillin can for prevention and treatment of scarlet fever or against rheumatic fever are used (bacterial infection of the nose and throat). Even with tooth or jaw surgery the drug is used to treat an endocarditis endocarditis prevent. Its mechanism of action could be due to binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, thus propicillin may inhibit the third and last stage of bacterial cell wall synthesis
