Clarithromycin bests erythromycin against community-acquired pneumonia

Saudi Arabia: In adults and adolescents, erythromycin is less effective than clarithromycin as empiric therapy for community-acquired pneumonia (CAP), says a new article published in the Journal of Infection and Chemotherapy.

It is controversial whether erythromycin is as effective as other macrolides in the treatment of community-acquired pneumonia. As a result, Noha Ashy and colleagues undertook this study to evaluate the effectiveness of erythromycin with clarithromycin and azithromycin.

For this experiment, a meta-analysis of randomized controlled trials (RCTs) of adults or adolescents with CAP comparing the effectiveness of erythromycin monotherapy to either azithromycin or clarithromycin was done. To acquire relevant data, the PubMed, EMBASE, and Cochrane Library databases, as well as three clinical trial registries, were searched up to November 02, 2021. Risk ratios with 95 percent confidence intervals were calculated using heterogeneity and random-effects models.

The key findings of this study were as follows:

1. Four randomized controlled trials (RCTs) with a total of 472 patients were included to examine the therapeutic effectiveness of erythromycin vs clarithromycin.

2. There were no studies that compared erythromycin monotherapy to azithromycin monotherapy.

3. When compared to clarithromycin, erythromycin was linked with considerably reduced rates of clinical success, clinical cure, and radiological success.

4. The researchers stated that erythromycin should be explored when clarithromycin and azithromycin are in low supply or when erythromycin may be more economical to the patient.

5. They reasoned that clarithromycin's improved effectiveness was due to a longer half-life, greater plasma concentration, and increased action against a broader range of CAP pathogens such as H influenzae.

In conclusion, because erythromycin is less effective and has a high discontinuation rate due to gastrointestinal side effects, it should not be chosen for the treatment of CAP unless other macrolides cannot be used and clinical practice guidelines must be followed. state this clearly.
