4.9 Overdose

Medical observation is recommended in cases of overdosage.

Sodium cromoglicate is poorly absorbed both from the eye and from the gastrointestinal tract.

5. Pharmacological properties
5.1 Pharmacodynamic properties

Sodium cromoglicate inhibits the degranulation of sensitised mast cells which normally occurs after exposure to allergens and thereby prevents the release of allergic mediators such as histamine.

5.2 Pharmacokinetic properties

Sodium cromoglicate is poorly absorbed from the eye (approximately 0.03% in healthy volunteers) due to its lipid insolubility. Orally, it is poorly absorbed from the gastrointestinal tract with a reported bioavailability of 1%. Systemically, sodium cromoglicate is excreted unchanged in the bile and urine.

Trace amounts have been detected in the aqueous humour of rabbit eyes up to 24 hours after administration.
