Azithromycin, the active ingredient in Zithromax and the Z-Pack, belongs to a class of antibiotics called macrolides. It works by inhibiting the growth of bacteria by interfering with their protein synthesis, effectively stopping the bacteria from multiplying and allowing the body’s immune system to eliminate the infection. The medication is available in various forms, including Zithromax 500 mg tablets, Zithromax Z-Pak, and Zithromax 250 mg doses, providing flexibility depending on the type and severity of the infection. The Z-Pack’s ease of use, with its reduced pill count, enhances patient compliance, leading to better outcomes in treating bacterial infections.
