What are the cephalosporin antibiotics?

Cephalosporins generally refer to antibiotics belonging to the cephalosporin class, which fall under the broader category of β-lactam antibiotics. These agents disrupt bacterial cell walls and exert bactericidal effects primarily during the active replication phase of bacteria. They exhibit strong selectivity against bacteria while posing virtually no toxicity to humans. Key advantages include a broad antimicrobial spectrum, potent antibacterial activity, and resistance to penicillinase. So, what are the commonly used cephalosporin anti-inflammatory drugs? The following section addresses this question.

Which Drugs Belong to the Cephalosporin Class?

Cephalosporins are conventionally classified into four generations. First-generation cephalosporins include injectable agents such as cefazolin and cefradine, and oral formulations such as cephalexin and cefadroxil—commonly indicated for respiratory tract infections, skin and soft tissue infections, and urinary and genital tract infections. Second-generation cephalosporins possess a broader antimicrobial spectrum and enhanced antibacterial activity compared with first-generation agents, along with reduced nephrotoxicity. Injectable forms include cefuroxime, cefoxitin, and cefmetazole; oral preparations include cefuroxime axetil and cefaclor. Third-generation cephalosporins demonstrate an even broader antimicrobial spectrum, stronger antibacterial activity, wider tissue distribution, and lower human toxicity. Injectable agents include cefotaxime, ceftazidime, ceftriaxone, cefoperazone, and ceftizoxime; oral formulations include cefixime, cefpodoxime proxetil, and cefetamet pivoxil. Fourth-generation cephalosporins offer the broadest antimicrobial spectrum among all generations, surpassing those of the first three generations. Due to their extremely low potential for cross-allergenicity with penicillins, they are administered intravenously—for example, cefepime and cefpirome—to treat serious infections.

Additional Information: Risks of Combining Cephalosporins with Alcohol

1. Acetaldehyde Toxicity

Symptoms typically include chest tightness, shortness of breath, hypotension, and generalized fatigue. After alcohol ingestion, the body’s alcohol-metabolizing enzymes normally break down ethanol into acetaldehyde and subsequently into acetate for elimination, thereby minimizing systemic toxicity. However, concurrent administration of certain cephalosporins can inhibit aldehyde dehydrogenase, leading to accumulation of acetaldehyde and resulting in acetaldehyde toxicity.

2. Reduced Drug Efficacy

Alcohol suppresses hepatic secretion of drug-metabolizing enzymes. When consumed concurrently with cephalosporins, it may impair drug absorption and metabolism, thereby diminishing therapeutic efficacy. Therefore, patients are strongly advised to abstain from alcohol during cephalosporin therapy—not only to preserve drug effectiveness but also to safeguard overall health.

3. Disulfiram-like Reaction

Consumption of alcohol while taking certain cephalosporins may trigger a disulfiram-like reaction, characterized by facial flushing, tachycardia, dyspnea, and other symptoms. In severe cases, this reaction may be life-threatening. Patients prescribed medications known to provoke disulfiram-like reactions—including specific cephalosporins—must strictly avoid alcohol intake.
