Used primarily as an antibacterial agent, especially in the treatment of respiratory tract infections caused by susceptible organisms. It is effective against a range of Gram-positive bacteria and some Gram-negative bacteria, making it useful in managing infections such as pharyngitis, tonsillitis, and bronchitis. Commonly prescribed in pediatric and adult populations where penicillin allergy is a concern, it serves as an alternative to other macrolide antibiotics. Also utilized in some regions for the prevention of toxoplasmosis in pregnant women. Its acetylated form enhances absorption and bioavailability when administered orally, contributing to more consistent therapeutic levels.
