| Mechanism of Action： |
Ticarcillin/Clavulanic acid contains a β-lactam ring that can be cleaved by β-lactamases, resulting in inactivation of the antibiotic. Those bacteria that can express β-lactamases are, therefore, resistant to β-lactam antibiotics. Due, at least in part, to the common β-lactam ring, ticarcillin can cause reactions in patients allergic to penicillin. Ticarcillin is also often paired with a β-lactamase inhibitor such as clavulanic acid. |
| Comments： |
Ticarcillin-Clavulanic acid is a carboxypenicillin. It is almost invariably sold and used in combination with clavulanate as Timentin. Because it is a penicillin, it also falls within the larger class of beta-lactam antibiotics. Its main clinical use is as an injectable antibiotic for the treatment of gram-negative bacteria, in particular, Pseudomonas aeruginosa. |
