Azithromycin 500 mg is often prescribed for short durations, typically 3 days, due to its unique pharmacokinetic properties. This antibiotic has a prolonged half-life, allowing for sustained therapeutic levels in the body after completion of the short course.
Additionally, its broad spectrum of activity and effectiveness against various bacterial infections, particularly respiratory and sexually transmitted infections, make it suitable for short-term treatment regimens, minimizing the risk of antibiotic resistance and side effects.
