Axinat Inhaler, Inhalation Capsule

Axinat stimulates intracellular adenyl cyclase, the enzyme that catalyses the conversion of ATP to cyclic-3',5'-adenosine monophosphate (cAMP) resulting in relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from mast cells.


Inhaled Axinat exerts a significant bronchodilating effect within 10 to 20 minutes of single-dose administration with asthma and this effect lasts for up to 12 hours or more.    Axinat has a beneficial effect on airway mucociliary clearance that will reduce the incidence of respiratory tract infections.    

Axinat produces a significant protective effect against Exercise Induced Asthma (EIA) for up to 9 to 12 hours in both adolescents and adults.    

Axinat improves the overnight PEFR (Peak Expiratory Flow Rate) and controls the symptoms of the patients with nocturnal asthma. The use of Axinat avoids exposure of children to theophylline or high-dose corticosteroid, with their attendants risks.     

Addition of Axinat to inhaled corticosteroid therapy is significantly more effective in terms of an improvement in lung function, symptom control and a reduction in the use of rescue bronchodilator therapy (use of short acting beta2-agonist).    

Addition of Axinat to inhaled corticosteroid therapy also significantly reduces the use of inhaled corticosteroids

Axinat is also used to associated treatment for these conditions: Asthma, Chronic Obstructive Pulmonary Disease (COPD), Exercise-Induced Bronchospasm
