What is the difference between azithromycin and erythromycin? Both of these antibiotics belong to the macrolide class, but they have different mechanisms of action and side effects. Azithromycin is a more potent antibiotic, while erythromycin has a longer half-life. Erythromycin is also more likely to cause gastrointestinal disturbances than azithromycin.
What is Azithromycin?
Azithromycin is a prescription medication used to treat a variety of bacterial infections. This medication belongs to a class of drugs called macrolide antibiotics. It works by stopping the growth of bacteria. Azithromycin is available as an oral tablet, oral suspension, and eye drop. The oral tablet is usually taken once daily for 5 days or as directed by your doctor. The oral suspension is taken on an empty stomach, at least 1 hour before or 2 hours after a meal, as directed by your doctor. Shake the suspension well before each use. Measure the liquid with a special dose-measuring spoon or cup, not a regular tablespoon. If you do not have a dose-measuring device, ask your pharmacist for one. The eye drop is usually applied 3 times daily for 5 days or as directed by your doctor.
What is Erythromycin?
Erythromycin is a macrolide antibiotic used to treat bacterial infections. It works by inhibiting the synthesis of proteins in bacteria, which results in the death of the bacteria. Erythromycin is effective against a wide range of bacteria, including streptococci, pneumonia, and mycoplasma. It is also used to prevent heart infections in people with certain medical conditions. Erythromycin is available in oral, topical, and injectable forms. Side effects of erythromycin include nausea, vomiting, diarrhea, and abdominal pain. Serious side effects include liver failure, hearing loss, and QT prolongation. Erythromycin should not be used by pregnant women or people with certain medical conditions.
Difference between Azithromycin and Erythromycin
Both azithromycin and erythromycin are antibiotics that belong to the macrolide class. They work by preventing bacteria from producing proteins that are essential for their growth. Azithromycin is more effective than erythromycin against a wider range of bacteria, including those that cause respiratory infections. It is also better tolerated by patients, with fewer side effects. Erythromycin is still used for certain infections, such as whooping cough, but azithromycin is generally the preferred choice.
Conclusion
Azithromycin and erythromycin are both antibiotics that treat a variety of infections, but there is a slight difference between the two. Erythromycin is effective against more types of bacteria than azithromycin and can be used to prevent heart problems in those with certain health conditions. However, azithromycin is taken as a single pill while erythromycin must be taken several times per day.
