cefotaxime + colistin + tobramycin

A combination antibiotic therapy consisting of cefotaxime (a third-generation cephalosporin), colistin (a polymyxin), and tobramycin (an aminoglycoside). This triple combination provides broad-spectrum coverage against Gram-positive and Gram-negative bacteria, including multidrug-resistant strains. The combination works through multiple mechanisms: cefotaxime inhibits bacterial cell wall synthesis, tobramycin inhibits bacterial protein synthesis, and colistin disrupts bacterial cell membranes. This synergistic approach is particularly valuable for treating severe infections caused by resistant pathogens, especially Pseudomonas aeruginosa.
