What are Tienam ampoules IV 0.5 g (Primaxin, Imipenem, Cilastatin)?

Tienam ampoules, composed of imipenem hydrate and cilastatin sodium, exhibit their therapeutic effects through a specific mechanism of action. Imipenem hydrate is a potent antibiotic that belongs to the carbapenem class. It functions by inhibiting the synthesis of bacterial cell walls, thereby disrupting their structural integrity. This leads to bacterial cell death as a result of osmotic instability. Imipenem's broad-spectrum activity enables it to effectively combat a wide range of gram-positive and gram-negative bacteria, making it useful in treating various infections.

Cilastatin sodium, on the other hand, serves a different purpose. It is administered alongside imipenem to prevent the degradation of imipenem by renal dehydropeptidase enzymes in the kidneys. This combination helps to maintain adequate levels of imipenem in the bloodstream and enhances its therapeutic effectiveness.

The synergistic action of imipenem hydrate and cilastatin sodium in Tienam ampoules contributes to their clinical efficacy in treating severe bacterial infections.
