Positrin

Positrin is a macrolide antibiotic containing erythromycin ethylsuccinate as its active ingredient. It is primarily used to treat a wide range of bacterial infections, including upper and lower respiratory tract infections caused by sensitive strains of *Streptococci*, *Staphylococci*, *Pneumococci*, *Haemophilus influenzae*, *Bordetella pertussis*, and *Corynebacterium diphtheriae*. Additionally, it is indicated for genitourinary infections caused by *Chlamydia*, *Staphylococcus aureus*, and *Treponema pallidum*. Positrin serves as an effective alternative for patients with penicillin allergies. The drug exerts its antibacterial effect by binding to the 50S ribosomal subunit of susceptible microorganisms, thereby inhibiting RNA-dependent protein synthesis. It is marketed by Sigmacorp in Bolivia and is available in both coated tablet and oral suspension formulations.
