Spiramycin is used to treat respiratory tract infections (such as bronchitis, pneumonia, and sinusitis), skin and soft tissue infections, and is particularly valuable in treating and preventing toxoplasmosis, especially during pregnancy when other antibiotics may be contraindicated.
As a macrolide antibiotic, spiramycin binds to the bacterial 50S ribosomal subunit, inhibiting protein synthesis and preventing bacterial growth and replication.
Spiramycin is generally well-tolerated with gastrointestinal symptoms being the most common side effects. It should be used with caution in patients with liver impairment. Always complete the full course of treatment as prescribed, even if symptoms improve earlier.
