A drug which inhibits or suppresses most inflammatory responses of an allergic, bacterial, traumatic or anaphylactic origin, as well as being immunosuppressant. They include the corticosteroids (e.g. betamethasone, dexamethasone, fluorometholone, hydrocortisone acetate, loteprednol etabonate, prednisolone, rimexolone, triamcinolone). They are sometimes combined with an antibiotic drug (e.g. betamethasone combined with neomycin or sulfacetamide, dexamethasone combined with neomycin or polymyxin B). Corticosteroids have side effects, such as enhancing the activity of herpes simplex virus, fungal overgrowth, raising intraocular pressure or cataract formation.There are other antiinflammatory drugs that are non-steroidal (NSAID) and have little toxicity. They act mainly by blocking prostaglandin synthesis. These include diclofenac sodium, flurbiprofen sodium, indomethacin, ketorolac, nepafenac and oxyphenbutazone. See immunosuppressants; steroid.
A chronic inflammatory lipogranuloma due to retention of the secretion (such as blocked ducts) of a meibomian gland in the tarsus of an eyelid. It is characterized by a gradual painless swelling of the gland without marked inflammatory signs and sometimes astigmatism which is induced by the cyst pressing on the cornea (Fig. C5). Small chalazia may disappear spontaneously but large ones usually have to be incised and curetted (i.e. removal of the pus with a scraper) through a tarsal incision. Resolution may also occur after local injection of a corticosteroid drug (e.g. dexamethasone or triamcinolone). Syn. meibomian cyst (although it is not a true cyst because its walls are made of granulomatous tissue and not lined with epithelium). See internal hordeolum.
