BANAN vs KEFLEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BANAN is a potassium-channel opener that hyperpolarizes smooth muscle cells, leading to vasodilation and reduced peripheral vascular resistance.
Cephalexin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.

250-500 mg orally every 6 hours; maximum 4 g/day.

2.5 hours (normal renal function); prolonged to 6-8 hours in severe renal impairment
0.5–1.2 hours in patients with normal renal function (CrCl >50 mL/min); prolonged to >20 hours in ESRD.
Renal: 70% unchanged; biliary: 20%; fecal: 10%
Primarily renal (90% or more unchanged via glomerular filtration and tubular secretion); small amounts biliary/fecal (<5%).
