Mirolast

Mirolast Uses, Dosage, Side Effects, Food Interaction and all others data.

Mirolast binds to the histamine H1 receptor. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine. Mirolast has also been observed to inhibit antigen-stimulated calcium ion influx into mast cells through the blockage of calcium channels. Mirolast inhibits the chemotaxis of eosinophils into ocular tissue, and prevents inflammatory mediator release from human eosinophils.

Mirolast is used for the prophylactic treatment of itching of the eye associated with allergic conjunctivitis. Mirolast potassium is a mast cell stabilizer that inhibits the in vivo Type I immediate hypersensitivity reaction. Mirolast inhibits the antigen-induced release of inflammatory mediators (e.g., histamine, leukotriene C4, D4, E4) from human mast cells. Allergic reactions lead to cell-degranulation and the release of histamine (and other chemical mediators) from the mast cell or basophil. Once released, histamine can react with local or widespread tissues through histamine receptors. Histamine, acting on H1-receptors, produces pruritis and vasodilatation (allowing blood fluids to enter the area to cause swelling). Mirolast is a histamine H1 antagonist. It competes with histamine for the normal H1-receptor sites on effector cells of blood vessels to provide effective, temporary relief of watery and itchy eyes.

How Mirolast works

Mirolast binds to the histamine H₁ receptor. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine. Mirolast has also been observed to inhibit antigen-stimulated calcium ion influx into mast cells through the blockage of calcium channels. Mirolast inhibits the chemotaxis of eosinophils into ocular tissue, and prevents inflammatory mediator release from human eosinophils.

Dosage
