Cromil is an anti-allergic produact. Disodium cromoglycate inhibits the release of allergic reactions mediators from sensitized mast cells. Such mechanism prevents both immediate and delayed response to immunologic and other stimuli. Disodium cromoglycate activity seems to be connected to the intracellular reduction in ca++, the increase of cAMP due to the phosphodiesterase enzyme inhibition and to the phosphorylation of a 78,000- dalton membreance protein. In vitro, disodium cromoglycate has not a direct effect on preparation of unstriated musculature nor does it carry out an antagonistic activity on acetylcholine or histamine.
When administered orally, disodium cromoglycate is very poorly absorbed (about 1%) in the gastrointestinal tract and is excreted mainly through the urine and bile. Under ideal circumstances, 10% or less of inhaled disodium cromoglycate is systemically absorbed. Peak concentration in plasma occur within 15 minutes of inhalation and the biological half-life ranges from 45 to 100 minutes. The terminal half-time of elimination following intravenous administration is about 20 minutes. Several pharmacokinetic studies have demonstrated that systemic absorption following topical administration is poor. Repeated administration of an ophthalmic solution 4% has produced 0.03% absorption. Through the nasolacrymal duct the drug reaches the gastrointestinal tract where it is absorbed. After instillation in the conjunctival sac low concentrations of drug have been found the ocular and cerebral tissues.
Cromil Eye Drops is used primarily in the prophylaxis of allergic eye conditions such as hay-fever conjunctivitis. Acute and chronic allergic coniunctivitis, vernal keratoconjunctivitis and giant papillary conjunctivitis.
It should not be given to the patients with known hypersensitivity to any of its components.
A transient stinging or burning sensation may occur after instillation, which usually disappears with continued use.
