Infectious Disease Section 5.1- Antibiotics

This nursing pharmacology review provides a high-yield overview of the most important antibiotic classes used in clinical practice. The video explains how common antibiotics work, what infections they treat, and the major nursing considerations associated with each class. Key topics include penicillins, cephalosporins, macrolides, fluoroquinolones, tetracyclines, vancomycin, aminoglycosides, and sulfonamides. Emphasis is placed on side effects, black box warnings, allergy considerations, renal dosing, patient counseling, and critical monitoring parameters nurses should recognize in both inpatient and outpatient settings.

Erythromycin Pharmacology

Erythromycin uniquely has some potential benefit in the setting of gastroparesis. Azithromycin you will likely not see used for this indication.

Erythromycin binds the 50s subunit and ultimately prevents protein synthesis which is necessary for bacteria to grow and replicate.

QTc prolongation is a risk with all macrolide antibiotics (erythromycin included).

By inhibiting CYP3A4, erythromycin can be responsible for numerous drug interactions.
