Description

Cephalexin Monohydrate USP

Cephalexin Monohydrate USP is a high-purity first-generation cephalosporin antibacterial agent used in pharmaceutical formulations for the treatment of a wide range of bacterial infections. Compliant with United States Pharmacopeia (USP) standards, it is commonly utilized in oral dosage forms for both acute and chronic infection management.
Cephalexin Monohydrate is chemically designated as (6R,7R)-7-[(R)-2-Amino-2-Phenylacetamido]-3-Methyl-8-Oxo-5-Thia-1-Azabicyclo[4.2.0]Oct-2-Ene-2-Carboxylic Acid Monohydrate. It appears as a white to off-white crystalline powder that is slightly soluble in water and suitable for formulation into capsules, tablets, and oral suspensions.
In pharmaceutical and clinical applications, Cephalexin Monohydrate USP is used in:
• Oral capsule and tablet formulations for bacterial infections
• Treatment of respiratory tract, skin, and urinary tract infections
• Pediatric oral suspension formulations
• Broad-spectrum antibacterial therapy
• Research involving beta-lactam antibiotic mechanisms
• Pharmacokinetic and bioavailability studies
Cephalexin Monohydrate USP functions by inhibiting bacterial cell wall synthesis through binding to penicillin-binding proteins, leading to disruption of cell wall integrity and bacterial cell death. Its activity is primarily directed against Gram-Positive organisms and select Gram-Negative bacteria.
