Sodium Channel Blockers (SCBs)

by
Sodium Channel Blockers

Introduction Sodium (Na⁺) channels are integral membrane proteins responsible for the rapid upstroke (phase 0) of the action potential in excitable cells such as neurons and cardiomyocytes. By selectively perming sodium ions across membranes, these channels facilitate depolarization, triggering electrical signals essential for neurotransmission, skeletal muscle contraction, and cardiac conduction. As a result, therapeutic modulation … Read more

Pharmacology of Cephalosporin antibiotics

cephalosporins antibiotics

Cephalosporin antibiotics are beta-lactam antibiotics derived from Cephalosporium acremonium, classified by generations based on their antimicrobial spectra and pharmacokinetic properties. They are among the most utilized antibiotics globally, due to broad efficacy and good safety profile. I. Mechanism of Action Cephalosporins bind to bacterial penicillin-binding proteins (PBPs) and inhibit the final transpeptidation step of peptidoglycan synthesis in … Read more
