Medical uses
Azithromycin is used to treat diverse infections, including:
* Prevention and treatment of acute bacterial exacerbations of chronic obstructive pulmonary disease due to ''H. influenzae'', ''M. catarrhalis'', or ''S. pneumoniae''. The benefits of long-term prophylaxis must be weighed on a patient-by-patient basis against the risk of cardiovascular and other adverse effects.

Bacterial susceptibility
Azithromycin has relatively broad but shallow antibacterial activity. It inhibits some Gram-positive bacteria, some Gram-negative bacteria, and many atypical bacteria.
A strain of gonorrhea reported to be highly resistant to azithromycin was found in the population in 2015. ''Neisseria gonorrhoeae'' is normally susceptible to azithromycin, but the drug is not widely used as monotherapy due to a low barrier to resistance development.

, resulting in residual encephalopathy.
In 2013 the FDA issued a warning that azithromycin "can cause abnormal changes in the electrical activity of the heart that may lead to a potentially fatal irregular heart rhythm." The FDA noted in the warning a 2012 study that found the drug may increase the risk of death, especially in those with heart problems, compared with those on other antibiotics such as amoxicillin or no antibiotic. The warning indicated people with preexisting conditions are at particular risk, such as those with QT interval prolongation, low blood levels of potassium or magnesium, a slower than normal heart rate, or those who use certain drugs to treat abnormal heart rhythms.
It has been reported that azithromycin blocks autophagy and may predispose cystic fibrosis patients to mycobacterial infection.

Pharmacokinetics
Azithromycin is an acid-stable antibiotic, so it can be taken orally with no need of protection from gastric acids. It is readily absorbed, but absorption is greater on an empty stomach. Time to peak concentration (Tmax) in adults is 2.1 to 3.2 hours for oral dosage forms. Due to its high concentration in phagocytes
Phagocytes are cells that protect the body by ingesting harmful foreign particles, bacteria, and dead or dying cells. Their name comes from the Greek ', "to eat" or "devour", and "-cyte", the suffix in biology denoting "cell", from the Greek '' ...
, azithromycin is actively transported to the site of infection. During active phagocytosis, large concentrations are released. The concentration of azithromycin in the tissues can be over 50 times higher than in plasma due to ion trapping
In cell biology, ion trapping is the build-up of a higher concentration of a chemical across a cell membrane due to the pKa value of the chemical and difference of pH across the cell membrane. This results in basic chemicals accumulating in acid ...
and its high lipid solubility. Azithromycin's half-life allows a large single dose to be administered and yet maintain bacteriostatic levels in the infected tissue for several days.
Following a single dose of 500 mg, the apparent terminal elimination half-life of azithromycin is 68 hours. Biliary
