Piperacillin is a broad-spectrum semisynthetic, ampicillin-derived ureidopenicillin antibiotic. Piperacillin binds to penicillin binding proteins (PBP), the enzymes that catalyze the synthesis of peptidoglycan, a critical component of the bacterial cell wall. This blockade leads to the interruption of cell wall synthesis, consequently, leading to bacterial cell growth inhibition and cell lysis.

Piroxicam is a nonsteroidal anti-inflammatory drug of the oxicam class used to relieve the symptoms of painful inflammatory conditions like arthritis.

Potassium nitrite appears as a yellowish white crystalline solid. Noncombustible but accelerates the burning of all combustible material. If large quantities are involved in fire or if the combustible material is finely divided, an explosion may result. May explode under prolonged exposure to heat. Toxic oxides of nitrogen are produced in fires. Used to make […]

Penicillin is a group of Beta-lactam antibiotics used in the treatment of bacterial infections caused by susceptible, usually Gram-positive, organisms. beta-lactam antibiotics work by inhibiting the formation of peptidoglycan cross-links in the bacterial cell wall, which results in cytolysis.

Phenylbutazone is a member of the class of pyrazolidines that is 1,2-diphenylpyrazolidine-3,5-dione carrying a butyl group at the 4-position. It has a role as a non-narcotic analgesic, a non-steroidal anti-inflammatory drug, an antirheumatic drug, a peripheral nervous system drug, a metabolite and an EC 1.1.1.184 [carbonyl reductase (NADPH)] inhibitor.

Pipemidic Acid is a pyridopyrimidine antibiotic derivative of piromidic acid with activity against gram-negative bacteria, as well as some gram-positive bacteria. Pipemidic acid exhibits greater activity than piromidic acid or nalidixic acid and shows moderate activity against bacteria that are resistant to piromidic acid and nalidixic acid.

Prednisolone is a glucocorticoid that is prednisone in which the oxo group at position 11 has been reduced to the corresponding beta-hydroxy group. It is a drug metabolite of prednisone. It has a role as an adrenergic agent, an anti-inflammatory drug, an antineoplastic agent, an immunosuppressive agent, a drug metabolite, an environmental contaminant and a […]

Prilocaine is a toluidine derivative and intermediate-acting amino amide with local anesthetic property. Prilocaine stabilizes the neuronal membrane by preferential binding to and inhibiting depolarization of the voltage-gated sodium channel. This results in a decrease in membrane permeability and subsequent inhibition of the ionic sodium influx required for the initiation and conduction of impulses.

Procaine is a benzoic acid derivative with local anesthetic and antiarrhythmic properties. Procaine binds to and inhibits voltage-gated sodium channels, thereby inhibiting the ionic flux required for the initiation and conduction of impulses. In addition, this agent increases electrical excitation threshold, reduces rate of rise of action potential and slows nerve impulse propagation thereby causing […]

Clindamycin is a semisynthetic lincosamide antibiotic that has largely replaced lincomycin due to an improved side effect profile. Clindamycin inhibits bacterial protein synthesis by binding to bacterial 50S ribosomal subunits. It may be bacteriostatic or bactericidal depending on the organism and drug concentration.
