Mechanism and action
Augmentin: Amoxicillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), but is hydrolysed by beta-lactamase enzymes produced by some resistant bacteria. Toprol XL: Metoprolol selectively blocks beta-1 adrenergic receptors in the heart, reducing heart rate, contractility and atrioventricular conduction velocity, and lowering myocardial oxygen demand.
When Augmentin is preferred
