Flexyx drugs: Claramax

Claramax - General Information:

Claramax is a tricyclic antihistamine, which has a selective and peripheral H1-antagonist action. It is used to treat allergies. It has a long-lasting effect and does not cause drowsiness because it does not readily enter the central nervous system.

Pharmacology:

Claramax is a long-lasting antihistamine. Claramax is a second-generation H₁-receptor antagonist which has a selective and peripheral H1-antagonist action. Histamine is a chemical that causes many of the signs that are part of allergic reactions, for example, swelling of tissues. Histamine is released from histamine-storing cells (mast cells) and attaches to other cells that have receptors for histamine. The attachment of the histamine to the receptors causes the cell to be "activated," releasing other chemicals which produce the effects that we associate with allergy. Claramax blocks one type of receptor for histamine (the H1 receptor) and thus prevents activation of cells by histamine. Unlike most other antihistamines, Claramax does not enter the brain from the blood and, therefore, does not cause drowsiness.

Claramax for patients

Claramax Interactions

In two controlled crossover clinical pharmacology studies in healthy male (n=12 in each study) a nd female (n=12 in each study) volunteers, desloratadine 7.5 mg (1.5 times the daily dose) once daily was coadministered with erythromycin 500 mg every 8 hours or ketoconazole 200 mg every 12 hours for 10 days. In three separate controlled, parallel group clinical pharmacology studies, desloratadine at the clinical dose of 5 mg has been coadministered with azithromycin 500 mg followed by 250 mg once daily for 4 days (n=18) or with fluoxetine 20 mg once daily for 7 days after a 23 day pretreatment period with fluoxetine (n=18) or with cimetidine 600 mg every 12 hours for 14 days (n=18) under steady state conditions to normal healthy male and female volunteers. Although increased plasma concentrations (C _max and AUC 0-24 hrs) of desloratadine and 3-hydroxydesloratadine were observed , there were no clinically relevant changes in the safety profile of desloratadine, as assessed by electrocardiographic parameters (including the corrected QT interval), clinical laboratory tests, vital signs, and adverse events.

Additional information about Claramax

Claramax Indication: For the relief of symptoms of seasonal allergic rhinitis, pruritus, reduction in the number of hives in patients with chronic idiopathic urticaria.
Mechanism Of Action: Like other H1-blockers, Claramax competes with free histamine for binding at H₁-receptors in the GI tract, uterus, large blood vessels, and bronchial smooth muscle. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine.
