Actions and spectrum:
Piperacillin stops the last step of making the bacterial cell wall. It attaches to specific proteins in that wall called penicillin-binding proteins (PBPs). Bacteria have enzymes that can break down their own cell walls, called autolysins. Piperacillin may block something that usually stops those autolysins from working, causing the cell to burst open.

Pregnancy consideration:
Lactation:
Pregnancy category:
Category A: Studies that were well-controlled and met expectations revealed no risk to the fetus in either the first or second trimester.
<b>Category B: There was a lack of studies on pregnant women and no evidence of risk to the fetus in animal experiments.
Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.
Category D: adequate data with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.
Category X: Drugs listed in this category outweigh the risks over benefits. Hence, these categories of drugs need to be avoided by pregnant women.
Category N: There is no data available for the drug under this category
Pharmacology:
Piperacillin fights bacteria. It works against bacteria like Pseudomonas aeruginosa. This drug belongs to the antibiotic family. Doctors commonly prescribe Piperacillin to combat infections caused by susceptible organisms.
Pharmacodynamics:
Piperacillin, an antibiotic, fights bacterial infections. It works by blocking cell wall formation in bacteria. This stops certain gram-positive bacteria from growing. Piperacillin binds to proteins involved in cell wall synthesis. It can overcome many enzymes that break down antibiotics. These include beta-lactamases, penicillinases, and extended-spectrum types. So, piperacillin remains effective against a wide range of bacteria.
Pharmacokinetics:
Absorption
Piperacillin is not absorbed well when taken by mouth.
Distribution
After injecting 50 mg/kg into the vein in newborns, it spreads through a volume of 101 ml/kg.
Metabolism
Piperacillin does not break down much.
Elimination and excretion
Mostly, it leaves the body when the kidneys filter or secrete it into urine. Most of the drug stays unchanged. It has a short-lasting effect because its half-life, the time it takes to decrease by half, is only 36 to 72 minutes.
Administration:
To be administered as suggested by the physician
Patient Information Leaflet:
Pronunciation: pi-per-i-sil-in
Use: This broad-range antibiotic fights certain infections. It treats urinary tract troubles, pneumonia from everyday life, acute bile duct inflammation, moderate and severe illnesses, simple gonorrhea cases, and pseudomonas illnesses too.
