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...

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...

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...

This cream contains three active ingredients Fluocinolone Acetonide, Hydroquinone and Tretinoin. All of them are used to treat melasma. However, the mechanism of action of the active ingredients in This cream in the treatment of melasma is unknown bu...

Fluocinolone acetonide is a corticosteroid primarily used in dermatology to reduce skin inflammation and relieve itching. It is a synthetic hydrocortisone derivative. Fluocinolone acetonide was also found to strongly potentiate TGF-&...

Ramipril is an angiotensin converting enzyme (ACE) inhibitor, which after hydrolysis to ramiprilat, blocks the conversion of angiotensin I to the vasoconstrictor substance, angiotensin II. So, inhibition of ACE by ramipril results in...

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...

Amitriptyline is a tricyclic antidepressant and Chlordiazepoxide is an anxiolytic. Amitriptyline inhibits the reuptake of norepinephrine and serotonin in the brain. This interference with the reuptake is responsible for the antidepressant activity of...

Iloperidone shows high affinity and maximal receptor occupancy for dopamine D2 receptors in the caudate nucleus and putamen of the brains of schizophrenic patients. The improvement in cognition is attributed to iloperidone's high affinity for α...

Imipramine works by inhibiting the neuronal reuptake of the neurotransmitters norepinephrine and serotonin. It binds the sodium-dependent serotonin transporter and sodium-dependent norepinephrine transporter reducing the reuptake of norepinephrine an...

Hydroxyzine Hydrochloride is an anxiolytic antihistamine of the piperazine class which is a H1 receptor antagonist. Hydroxyzine is not a cortical depressant, but its action may be due to a suppression of activity in certain key regions of the subcort...

Valsartan is an oral medication that belongs to a class of drugs called angiotensin receptor blockers (ARBs). It is orally active and specific angiotensin II antagonist acting on the AT1 subtype. Angiotensin's attachment to the recep...

Triamterene directly inhibits the exchange of Na for K and hydrogen in the distal renal tubule. Hydrochlorothiazide increases the excretion of Na and Cl ions, and consequently of water, by reducing electrolyte reabsorption from the r...

Telmisartan: Angiotensin II is formed from angiotensin I in a reaction catalyzed by angiotensin-converting enzyme (ACE, kininase II). Angiotensin II is the principal pressor agent of the renin-angiotensin system, with effec...

Metformin is a biguanide antihyperglycemic agent, which improves glucose tolerance in patients with type 2 diabetes, lowering both basal and postprandial plasma glucose. Its pharmacological mechanisms of action are different from other classes of ora...

Haloperidol is a butyropherone derivative with antipsychotic properties that has been considered particularly effective in the management of hyperactivity, agitation and mania. Haloperidol is an effective neuroleptic and also possesses antiemetic pro...

Glucosamine is a naturally occurring compound for the body's production of joint lubricants and shock absorbers necessary to maintain healthy cartilage and joint function. Glucosamine hydrochloride is a prodrug for glucosamine that is well absorbed a...

Thiazides such as hydrochlorothiazide promote water loss from the body (diuretics). They inhibit Na⁺/Cl^- reabsorption from the distal convoluted tubules in the kidneys. Thiazides also cause loss of potassium and an increase in s...
