Piperacillin with tazobactam is administered through an intravenous (IV) method, where it is infused into the bloodstream over a period of 30 minutes to 4 hours so that the medication is delivered slowly and steadily. [10] [11] The minimal duration of the infusion of 30 minutes is set for both adults and pediatric patients. [11]
Piperacillin is a broad-spectrum β-lactam antibiotic of the ureidopenicillin class. [1] The chemical structure of piperacillin and other ureidopenicillins incorporates a polar side chain that enhances penetration into Gram-negative bacteria and reduces susceptibility to cleavage by Gram-negative beta lactamase enzymes.
Tazobactam is a pharmaceutical drug that inhibits the action of bacterial β-lactamases, especially those belonging to the SHV-1 and TEM groups. It is commonly used as its sodium salt , tazobactam sodium.
Piperacillin; Mezlocillin; They are mostly ampicillin derivatives in which the amino acid side chain has been converted to a variety of cyclic ureas. It is speculated that the added side chain mimics a longer segment of the peptidoglycan chain, more than ampicillin, and thus would bind more easily to the penicillin-binding proteins.
Doses of less than one gram may be administered as an IV bolus, whereas imipenem is usually administered as a 20-minute to one hour infusion. Meropenem is somewhat less potent than imipenem against gram-positive pathogens, and somewhat more potent against gram-negative infections.
Unlike the case of beta-lactam antibiotics, the inhibitors act as suicide substrates (tazobactam and sulbactam) which ultimately leads to the degradation of the beta-lactamase. [7] Avibactam on the other hand does not contain a beta-lactam ring (non beta-lactam beta-lactamase inhibitor), and instead binds reversibly .
The side effects of penicillin are bodily responses to penicillin and closely related antibiotics that do not relate directly to its effect on bacteria. A side effect is an effect that is not intended with normal dosing. [1] Some of these reactions are visible and some occur in the body's organs or blood.
Adverse effects to monobactams can include skin rash and occasional abnormal liver functions. [citation needed]Monobactam antibiotics exhibit no IgE cross-reactivity reactions with penicillin but have shown some cross reactivity with cephalosporins, most notably ceftazidime, which contains an identical side chain as aztreonam.
