Neurotoxin from Clostridium botulinum; prevents ACh release from presynaptic membrane, causing temporary calming of muscle contractions by blocking the transmission of nerve impulses.

Botulinum Toxin Type A blocks the signals between the n...

Cyclobenzaprine, a centrally-acting skeletal muscle relaxant, is structurally related to tricyclic antidepressants, thus they share similar properties. It acts on the brain stem, decreasing tonic-somatic motor activities influencing both the α...

The mechanism of action of Dapoxetine in premature ejaculation is presumed to be linked to the inhibition of neuronal reuptake of serotonin and the subsequent potentiation of the neurotransmitter's action at pre-and post synaptic receptors. Human eja...

Desloratadine, the major active metabolite of Loratadine, is a non-sedating; long acting tricyclic histamine antagonist with selective H1-receptor histamine antagonist activity. Desloratadine also inhibits histamine release from human mast cell.

The antibacterial action of Gatifoxacin results from inhibition of DNA gyrase and topoisomerase IV. DNA gyrase is an essential enzyme that is involved in the replication, transcription and repair of bacterial DNA. Topoisomerase IV is an enzyme known...

Dapagliflozin is an inhibitor of Sodium-glucose co-transporter 2 (SGLT2). Sodium-glucose co-transporter 2 (SGLT2), expressed in the proximal renal tubules, is responsible for the majority of the reabsorption of filtered glucose from the tubular lumen...

Dextran produce expansion of plasma volume. It also reduces blood viscosity and inhibits sludging or aggregation of red blood cells.

Sodium chloride is the major extracellular cation. It is important...

Diclofenac Sodium is a potent nonsteroidal antiinflammatory drug (NSAID) with marked analgesic and antipyretic properties. It also has some uricosuric effects. The action of Diclofenac appeared to be associated with the inhibition of prostaglandin sy...

Dilofenac Sodium is a potent non-steroidal anti-inflammatory drug (NSAID) with pronounced anti-rheumatic, anti-inflammatory, analgesic and antipyretic properties. It has also some uricosuric effect. Diclofenac exerts its effect by inhibiting prostagl...

It is a combination product containing Diclofenac Sodium, a nonsteroidal anti-inflammatory drug (NSAID) with analgesic properties and Misoprostol, a gastrointestinal (GI) mucosal protective prostaglandin E 1 analog. The mechanism of action of Diclofe...

Diclofenac Sodium works by blocking the action of cyclo-oxygenase. Cyclo-oxygenase is involved in the production of various chemicals in the body, some of which are known as prostaglandins. Prostaglandins are produced in response to injury or certain...

Dicycloverine hydrochloride is an antispasmodic and anticholinergic (antimuscarinic) agent. Chemically, it is [Bicyclohexyl-]1-carboxylic acid, 2-(diethylammo) ethyl ester, hydrochloride. Dicycloverine relieves smooth muscle spasm of the gastrointest...

Diloxanide is a luminal amoebicide which is hydrolysed in the gut, thus releasing the free diloxanide which acts as an amoebicide. It is given alone in asymptomatic cyst passers. For patients with active amoebic infections, it can be administered wit...

Diphenhydramine has anti-histaminic (H1-receptor), anti-emetic, anti-vertigo and sedative and hypnotic properties. The anti-histamine action occurs by blocking the spasmogenic and congestive effects of histamine by competing with histamine for H1 rec...

Dobutamine Hydrochloride is a direct-acting inotropic agent whose primary activity results from stimulation of cardiac adrenergic receptors; it produces comparatively mild chronotropic, hypertensive, arrhythmogenic and vasodilatory effects. In contra...

Diphenhydramine is an antihistamine and works as a topical anti-allergic and analgesic by blocking the releases of histamine at its sources. Zinc is used as a skin protectant.

Donepezil Hydrochloride is a centrally acting anticholinesterase agent. It binds reversibly with acetylcholinesterase and inactivates it, thus inhibiting hydrolysis of acetylcholine. As a result the concentration of acetylcholine increases at choline...

Dopamine is a preparation of Dopamine hydrochloride which can stimulate α, β and dopamine receptors. It is a natural catecholamine formed by the decarboxylation of 3,4-dihydroxyphenylalanine (DOPA). Dopamine is a precursor to norepinephrin...

Doxorubicin hydrochloride is a cytotoxic, anthracycline topoisomerase IIinhibitor. The cytotoxic effect of Doxorubicin HCl on malignant cells and its toxic effects on various organs are thought to be related to nucleotide base intercalation and cell...
