Overview
Cefotiam is a β-lactam antibiotic belonging to the second-generation cephalosporin class, developed to combine broader antibacterial coverage with improved stability against β-lactamases compared to first-generation agents. Introduced in the 1980s, cefotiam demonstrates particular efficacy against gram-negative bacteria while retaining activity against many gram-positive organisms. Its molecular structure features a characteristic cephalosporin core with specific side chains that enhance its pharmacokinetic properties and antimicrobial spectrum.
Physical and Chemical Properties
As a crystalline powder, cefotiam hydrochloride exhibits good water solubility, making it suitable for both oral and parenteral formulations. The compound shows stability in aqueous solutions within specific pH ranges but may degrade under extreme conditions. Key chemical properties include its zwitterionic nature at physiological pH, which influences its distribution in biological systems. The presence of both amino and carboxyl groups contributes to its amphoteric characteristics and affects its solubility profile across different pH environments.
Main Applications
In clinical practice, cefotiam is primarily employed for treating moderate to severe infections caused by susceptible organisms, including pneumonia, bronchitis, pyelonephritis, and postoperative infections. The antibiotic finds particular use in hospital settings where its broad spectrum covers common pathogens encountered in respiratory and urinary tract infections. Some formulations are specifically developed for surgical prophylaxis, leveraging the drug's favorable tissue penetration and pharmacokinetic profile.
Safety and Storage
Proper handling of cefotiam requires attention to potential allergic reactions, especially in individuals with known hypersensitivity to β-lactam antibiotics. Cross-reactivity with penicillins may occur in approximately 5-10% of cases. Storage should maintain product integrity by controlling temperature (15-25°C), humidity (below 60% RH), and light exposure. Long-term stability typically exceeds 24 months when stored in original packaging under recommended conditions. Special care should be taken to prevent contamination during repackaging operations.
B2B Procurement Guide
Pharmaceutical manufacturers sourcing cefotiam API should prioritize suppliers with demonstrated GMP compliance and proper documentation, including detailed certificates of analysis (COA) and stability data. Quality verification should include testing for potency, related substances, residual solvents, and microbiological purity. Regulatory requirements vary by market, with particular attention needed for exports to markets with stringent pharmaceutical standards such as the EU, US, or Japan. Consider establishing long-term supply agreements to mitigate price volatility in the antibiotic API market.
