PHARMACHOLOGIC EFFECT
Antiallergic agent, stabilizer of membranes of mast cells.
It inhibits the release of histamine, leukotrienes and other biologically active substances from mast cells. It is believed that the delay in the release of mediators occurs as a result of an indirect blockade of the penetration of calcium ions into the cells. It has been established that cromoglycic acid inhibits the migration of neutrophils, eosinophils, monocytes.
Prevents asthmatic reactions of immediate and delayed type after inhaling allergens and non-antigenic stimuli.

DRUG INTERACTION
When using cromoglycic acid with oral and inhalation forms of beta-adrenostimulants, oral and inhalation forms of GCS, theophylline and other methylxanthine derivatives, antihistamines, a potentiation effect is possible.
The combined use of cromoglycic acid and GCS can reduce the dose of the latter, and in some cases - completely cancel. During the dose reduction, the patient should be under close medical supervision, the rate of dose reduction should not exceed 10% per week.
