_Aridol Product Information - Singapore _ _ _ 1_ _ PRODUCT INFORMATION ARIDOL MANNITOL POWDER FOR INHALATION NAME Mannitol. Also known as D-mannitol. The empirical formula is C 6 H 14 O 6 . Molecular weight is 182.2 CAS number: 69-65-8. Structural Formula: DESCRIPTION Mannitol is a hexahydric alcohol. The powder is a white or almost white, crystalline powder of free- flowing granules. Mannitol is freely soluble in water, and very slightly soluble in alcohol. Mannitol shows polymorphism. Mannitol is the only ingredient in the contents of Aridol hard gelatin capsules. Colouring agents are used on the caps of the 5, 10, 20 and 40 mg capsules (the 0 mg capsule and the bodies of the other capsules are clear). The colouring agents are titanium dioxide (5, 10, 20 and 40 mg), yellow iron oxide (10 mg) and red iron oxide (20 and 40 mg). The delivered dose from each of the 5, 10, 20 and 40mg capsules is approximately 3, 8, 16 and 31mg, respectively. PHARMACOLOGY _PHARMACODYNAMICS _ When inhaled, mannitol induces an increase in osmolarity in the airways similar to other bronchial provocation tests such as hypertonic saline, exercise and the hyperpnea of dry air. The increase in osmolarity is associated with the release of a wide variety of mediators of bronchoconstriction from inflammatory cells within the airways. These mediators then act via specific receptors on bronchial smooth muscle to cause contraction and the airways to narrow. The airway response is most pronounced (hyperresponsiveness) in patients with asthma and exercise-induced asthma. The airway response to Aridol is measured using the forced expiratory volume in one second (FEV 1 ). The sensitivity to mannitol is reported as the delivered dose of mannitol to cause a 15% reduction in FEV 1 . The invo Прочитать полный документ
