Buy azithromycin online is a broad-spectrum antibiotic that works by inhibiting bacterial protein synthesis. It binds to the 50S ribosomal subunit of susceptible bacteria, blocking the production of essential proteins needed for growth and replication. Without these proteins, bacteria cannot multiply and eventually die, allowing the immune system to clear the infection. Azithromycin is effective against a variety of bacteria, making it useful for treating respiratory infections, skin infections, sexually transmitted diseases, and more. Its long half-life allows for once-daily dosing and shorter treatment durations, improving patient compliance and convenience. Always use it under medical supervision.
