AZITHRO-MAX 500 Tablet is a high-strength macrolide antibiotic formulation that contains 500 mg of Azithromycin per tablet. It is indicated for the treatment of a variety of infections caused by susceptible bacteria. These include infections of the upper and lower respiratory tracts, skin and soft tissue infections, certain sexually transmitted diseases, and otorhinolaryngological conditions. As an advanced formulation, AZITHRO-MAX 500 is designed to offer enhanced patient compliance, broad-spectrum efficacy, and targeted antimicrobial action.

Azithromycin, the active pharmaceutical ingredient in AZITHRO-MAX 500, is a derivative of erythromycin and belongs to the azalide subclass of macrolide antibiotics. It works by binding to the 50S ribosomal subunit of bacteria, thereby inhibiting bacterial protein synthesis. This bacteriostatic mechanism is effective against a wide array of Gram-positive and Gram-negative bacteria, including Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, Mycoplasma pneumoniae, Chlamydia trachomatis, and Neisseria gonorrhoeae.

One of the primary reasons for the global popularity of Azithromycin in 500 mg strength is its pharmacokinetic excellence. After oral administration, AZITHRO-MAX 500 is rapidly absorbed in the gastrointestinal tract and achieves peak plasma levels within two to three hours. The bioavailability of Azithromycin is further enhanced by its ability to concentrate in tissues and phagocytic cells, where it is transported directly to the site of infection. The drug remains active in tissues for an extended period, with a terminal elimination half-life of approximately 68 hours. This enables once-daily dosing and a shorter treatment course compared to other antibiotics, which significantly improves adherence, especially in outpatient and remote healthcare settings.

AZITHRO-MAX 500 is typically prescribed in conditions such as community-acquired pneumonia, bacterial bronchitis, acute bacterial sinusitis, and pharyngitis or tonsillitis caused by susceptible organisms. It is also effective in uncomplicated skin and skin structure infections, including erysipelas, impetigo, and infected wounds. In the field of sexual health, AZITHRO-MAX 500 is a first-line agent for uncomplicated genital infections due to Chlamydia trachomatis and in combination regimens for gonorrhea. Moreover, it is recommended in certain parasitic infections and is part of global health programs for controlling trachoma and yaws.
