Roxithromycin 150mg is a macrolide antibiotic used to treat various bacterial infections by inhibiting bacterial protein synthesis. It is effective against a range of respiratory, skin, and soft tissue infections. Roxithromycin works by binding to the bacterial ribosome, preventing the bacteria from synthesizing proteins necessary for their growth and reproduction. It is commonly prescribed for respiratory tract infections such as bronchitis and pneumonia, as well as ear infections, skin infections, and pharyngitis. Typically, Roxithromycin is taken once or twice daily, with a standard dosage of 150mg, depending on the infection being treated. This dosage is typically prescribed for uncomplicated infections and is known for its relatively lower side-effect profile compared to other antibiotics.
