Pharmacodynamics and pharmacokinetics
The mechanism of action is based on the stabilization of mast cell . The main active ingredient is cromoglycic acid . Intal prevents the process of degranulation of mast cells, blocks the flow of calcium into them, inhibits the release of leukotrienes, bradykinin, histamine and other bioactive components from mast cells.
The drug prevents the formation of bronchospasm. Most often used to prevent an allergic response.
With long-term use, there is a decrease in the frequency of asthma in bronchial asthma, the course of the disease is alleviated, and the need for the use of glucocorticosteroids and bronchodilators is reduced.
A stable effect is registered after ½-1 month of use. With a single use, the effect lasts up to five hours.
