Omadacycline mesylate is primarily used as an antibiotic to treat bacterial infections. It is effective against a range of gram-positive and gram-negative bacteria, including those resistant to other antibiotics. It is commonly prescribed for treating community-acquired bacterial pneumonia and acute bacterial skin and skin structure infections. The medication works by inhibiting protein synthesis in bacteria, thereby stopping their growth and spread. It is available in both intravenous and oral forms, providing flexibility in administration based on the severity of the infection and patient needs. Due to its broad-spectrum activity, it is often used when other antibiotics are ineffective or unsuitable.
