What Experts Say

Infectious disease specialists describe ceftazidime and avibactam as an important option for infections that no longer respond to standard antibiotics. Avibactam blocks enzymes that many resistant bacteria use to survive, allowing ceftazidime to work again against strains that would otherwise defeat it.

Doctors typically reserve this combination for hospitalized patients with confirmed or suspected multi-drug resistant infections. It is given through an intravenous drip, usually every eight hours, and dosing is adjusted based on kidney function and infection severity. Specialists also monitor blood tests during treatment to track how the infection responds.

Because resistant infections are becoming more common in hospitals across Pakistan, clinicians stress that this medicine should only be used when culture reports or clinical judgment confirm it is needed, to preserve its effectiveness for future patients. Overusing powerful antibiotics can encourage further resistance.
