Ticarcillin is a broad-spectrum, semi-synthetic penicillin antibacterial with antibacterial activity. Similar to carbenicillin in action, ticarcillin inactivates the penicillin-sensitive transpeptidase C-terminal area by aperture the lactam ring. This inactivation prevents the cross-linkage of peptidoglycan strands, thereby inhibiting the third and endure date of bacterial corpuscle bank synthesis. This leads to abridged bacterial corpuscle bank amalgam and eventually causes corpuscle lysis.
Ticarcillin is a semisynthetic antibacterial with a ample spectrum of antibacterial action adjoin abounding gram-positive and gram-negative aerobic and anaerobic bacteria. Ticarcillin is, however, affected to abasement by ß-lactamases, and therefore, the spectrum of action does not commonly cover bacilli which aftermath these enzymes.
