Levamisole is the active laevo-isomer of tetramisole. It works by paralysing susceptible intestinal worms which are then excreted from the intestines. Levamisole also enhances cellular immune responses in humans.

Lercanidipine is a selective calcium channel blocker of the dihydropyridine group and it inhibits the transmembrane influx of calcium into smooth muscle. The mechanism of its antihypertensive action is due to a direct relaxant effect on vascular smoo...

Irinotecan is a derivative of Camptothecin. Camptothecins interact specifically with the enzyme topoisomerase I, which relieves torsional strain in DNA by inducing reversible single-strand breaks. Irinotecan and its active metabolite SN-38 bind to th...

The active ingredient, Lysine hydrochloride is an essential amino acid, soluble in water; has been observed to promote in-situ cellular expansion in acute and chronic wound beds, in presence of blood plasma derived growth factor(s). The essential ami...

Ketamine is a rapid-acting, nonbarbiturate general anesthetic. It produces an anesthetic state characterized by profound analgesia. The anesthetic state produced by Ketamine has been termed "dissociative anesthesia" (A form of general anesthesia char...

Drotaverine HCl is a new potent synthetic antispasmodic drug which is readily absorbed from the intestine. Like papaverine, it acts directly on the smooth muscle fibers exceeding however, the antispasmodic effect of the standard preparations. Drotave...

Flucloxacillin is active against Gram-positive organisms including penicillinase producing strains. It has little activity against Gram-negative bacilli. Flucloxacillin acts by inhibiting the formation of cell wall of bacteria. Flucloxacillin is isox...

Flavoxate acts as a direct antagonist at muscarinic acetylcholine receptors in cholinergically innervated organs. Its anticholinergic-parasympatholytic action reduces the tonus of smooth muscle in the bladder, effectively reducing the number of requi...

The H1 histamine receptor is responsible for mediating hypersensitivity and allergic reactions. Exposure to allergen results in the degranulation of mast cells and basophils, which then release histamine and other inflammatory mediators. Histamine bi...

Epirubicin Hydrochloride, an anthracycline with cytotoxic properties. It inhibits DNA and RNA synthesis by steric obstruction after intercalating between DNA base pairs that triggers DNA cleavage by topoisomerase II. It also inhibits DNA helicase and...

Epinastine is a topically active antihistamine that antagonizes both histamine H₁ and H₂ receptors. Moreover, it has mast cell stabilizing activity and prevents the release of inflammatory mediators from the blood vessel. Epinas...

Ephedrine is a stimulant drug, belonging to a group of medicines known as sympathomimetics. Specifically it is both an alpha and beta adrenergic agonist. In addition, Ephedrine enhances the release of norepinephrine, a strong endogenous alpha agonist...

Eperisone is centrally-acting skeletal muscle relaxant used to improve myotonic symptoms.

Duloxetine Hydrochloride is a selective serotonin and norepinephrine reuptake inhibitor (SSNRI) for oral administration. Duloxetine is a less potent inhibitor of dopamine reuptake. Duloxetine has no significant affinity for dopaminergic, adrenergic,...

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...

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.

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...

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...

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...
