Paracetamol has analgesic and antipyretic properties with weak anti-inflammatory activity. Paracetamol (Acetaminophen) is thought to act primarily in the CNS, increasing the pain threshold by inhibiting both isoforms of cyclooxygenase, COX-1, COX-2,...

The efficacy of Paroxetine is presumed to be linked to potentiation of serotonergic activity in the central nervous system resulting from inhibition of neuronal reuptake of serotonin (5-hydroxy-tryptamine, 5 HT). Studies at clinically relevant doses...

Pazopanib is a multi-tyrosine kinase inhibitor of vascular endothelial growth factor receptor (VEGFR)-1, VEGFR 2, VEGFR-3, platelet-derived growth factor receptor (PDGFR)-α and -β, fibroblast growth factor receptor (FGFR)-1 and -3, cytokin...

Pefloxcin is a synthetic antibacterial agent, belongs to fluoroquinolone group. It exerts its action by inhibiting the subunit-A of DNA gyrase (Topoisomerase II). Pefloxcin is bactericidal and has a broad spectrum of activity.

Pethidine is a phenylpiperidine derivative opioid analgesic. It acts mainly as mu-receptor agonist. Like most, opioid analgesics, it mimics endogenous opioids by activating opioid receptors in the central and peripheral nervous system. It reduces the...

Tropicamide binds to and blocks the receptors in the muscles of the eye (muscarinic receptor M4). Tropicamide acts by blocking the responses of the iris sphincter muscle to the iris and ciliary muscles to cholinergic stimulation, producing dilation o...

Pilocarpine Hydrochloride directly stimulates cholinergic receptors. It produces contraction of the iris sphincter muscle, resulting in pupillary constriction (miosis); constriction of the ciliary muscle, resulting in increased accommodation; and red...

The main site of anesthetic action is the nerve cell membrane where proparacaine interferes with the large transient increase in the membrane permeability to sodium ions that is normally produced by a slight depolarization of the membrane. As the ane...

Nasal drop: Sodium Chloride nasal drop is a non-drug, isotonic saline solution that is used to moisturize nasal membranes. This formulation provides comfort for extensive and continuous use. Sodium Chloride 0.9% nasal wash moistures...

Pioglitazone depends on the presence of insulin for its mechanism of action. Pioglitazone decreases insulin resistance in the periphery and in the liver resulting in increased insulindependent glucose disposal and decreased hepatic g...

Silodosin is a selective antagonist of post-synaptic alpha-1 adrenoreceptors, which are located in the human prostate, bladder base, bladder neck, prostatic capsule and prostatic urethra. Blockade of these alpha-1 adrenoreceptors can cause smooth mus...

Sertraline has potent and selective inhibitory action on CNS neuronal reuptake of 5-HT resulting in increased 5-HT concentrations at the synaptic clefts, leading to facilitation of its sustained activity at the postsynaptic receptor sites. It ultimat...

This tablet combines two antihyperglycemic agents with complementary mechanisms of action to improve glycemic control in patients with type 2 diabetes. Sitagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, and Metformin HCl, a member of the biguan...

Ritodrine hydrochloride is a β2–adrenergic agonist. It relaxes the uterus by stimulating the β2–adrenergic receptors of the uterine muscle, which causes a decrease in the intensity and frequency of uterine contractions. Specific...

Vitamin B6 (pyridoxine) is a water-soluble vitamin used in the prophylaxis and treatment of vitamin B6 deficiency and peripheral neuropathy in those receiving isoniazid (isonicotinic acid hydrazide, INH). Vitamin B6 has been found to lower systolic a...

Propranolol Hydrochloride is a B-adrenergic receptor blocking drug which is widely used in hypertension and angina pectoris. Propranolol antagonizes catecholamines at B-adrenergic receptors, thus prevents excess rate and force of contraction of the h...

Expansol (6% Hydroxyethyl Starch 130/0.4 in 0.9% Sodium Chloride IV infusion) is a clear to slightly opalescent, colorless to slightly yellow, sterile, non-pyrogenic, isotonic solution. The chemical name of Hydroxyethyl Starch is poly (O-2-hydroxyeth...

Pralidoxime Chloride is an acetylcholinesterase reactivator. The principal action of Pralidoxime Chloride is to reactivate acetylcholinesterase (mainly outside of the central nervous system) which has been inactivated by phosphorylation due to an org...

Potassium Chloride is used for the treatment of hypokalaemia and of potassium deficiency states. Potassium ion is the principal intracellular cation of most body tissues. It participates in a number of essential physiological processes, including the...

Prasugrel is an thienopyridine and a prodrug which inhibits ADP receptors by irreversibly acting on the P2Y12 receptor on platelets. The active metabolite of prasugrel prevents binding of adenosine diphosphate (ADP) to its platelet receptor, impairin...
