1. What is Ospen and what is it used for

Ospen is an oral antibiotic belonging to the penicillin group, with strong antibacterial action. It works bactericidally on sensitive, multiplying microorganisms by inhibiting cell wall synthesis.
Ospen is indicated for:
treatmentof the following mild to moderate infections caused by penicillin-sensitive microorganisms:

• Ear, nose, and throat infections, including streptococcal infections (scarlet fever, pharyngitis, tonsillitis, rhinitis, sinusitis, acute otitis media, Vincent's angina);
• Respiratory tract infections: bacterial bronchitis, bacterial pneumonia, bronchopneumonia (as a continuation of treatment with injectable drugs);
• Skin and soft tissue infections: erysipelas, impetigo, purulent skin inflammation (e.g., ecthyma, folliculitis), abscesses, carbuncles; preventionof rheumatic fever.

In the treatment of severe pneumonia, lung abscess, sepsis, endocarditis, myocarditis, meningitis, arthritis, and osteomyelitis, penicillin should be administered parenterally in the acute phase of infection.
