How Does Exef Work?

Exef provides bactericidal action through bacterial cell wall disruption:

1. Cell Wall Synthesis Inhibition: Binds to penicillin-binding proteins in bacterial cell walls
2. Bactericidal Activity: Causes bacterial cell death by disrupting cell wall integrity
3. Broad Spectrum Coverage: Effective against gram-positive and gram-negative bacteria
4. Beta-Lactamase Stability: Resistant to degradation by many beta-lactamase enzymes

Exef Side Effects and Warnings

Common side effects include diarrhea, nausea, vomiting, abdominal discomfort, and headache. Most adverse effects are mild and self-limiting.

Serious Considerations

1. Hypersensitivity Reactions: Cross-reactivity possible in penicillin-allergic patients
2. C.difficile Diarrhea: May cause antibiotic-associated pseudomembranous colitis
3. Renal Impairment: Dose adjustment required in patients with renal dysfunction
4. False Positive Urine Glucose: May interfere with certain urine glucose tests
5. Drug Interactions: Probenecid may increase cefuroxime concentrations
