DB06794


Description:

Lodoxamide is a mast-cell stabilizer for topical administration into the eye. Mast-cell stabilizers, first one approved being cromolyn sodium, are used in treatment of ocular hypersensitivity reactions such as vernal conjunctivitis. These conditions often require treatment with anti-inflammatory medications such as ophthalmic NSAIDs or topical steroids which may cause systemic or toxic effects long-term. Although less effective than topical steroids at decreasing inflammation, mast-cell stabilizers offer another treatment option and exhibit minimal adverse effects. Lodoxamide is marketed under the brand name Alomide by Alcon. [DrugBank]

Targets:

Although lodoxamide's precise mechanism of action is unknown, it is postulated that it prevents calcium influx into mast cells upon antigen stimulation and therefore stabilizes the membrane. By stabilizing the mast cell membrane from degranulation, lodoxamide consequently inhibits the release of intracellular histamine and other chemoattractant factors that primarily cause ocular symptoms. Lodoxamide's mechanism of action may be similar to cromolyn sodium, as both exhibit cross-tachyphylaxis. [DrugBank]

Pharmacodynamics:

Lodoxamide is a mast cell stabilizer that inhibits the in vivo Type 1 immediate hypersensitivity reaction. Lodoxamide therapy inhibits the increases in cutaneous vascular permeability that are associated with reagin or IgE and antigen-mediated reactions. [DrugBank]
