Azithromycin（Cat No.:I046404）is a broad-spectrum macrolide antibiotic with the molecular formula C38H72N2O12, used to treat various bacterial infections, including respiratory tract infections, skin infections, sexually transmitted diseases, and otitis media. It works by binding to the 50S ribosomal subunit of bacteria, inhibiting protein synthesis and thereby stopping bacterial growth. Azithromycin is known for its extended half-life, allowing for once-daily dosing and shorter treatment durations. It is typically administered orally or intravenously. Common side effects include gastrointestinal upset, headache, and dizziness. It is generally well-tolerated and widely prescribed in clinical practice.
