Apprehension (film), a 1982 film by Lothar Warneke
Drug trials have found it to be as efficient as anti-VEGF drugs in eyes with artificial lenses over a two-year period. A systematic review did not find any evidence of any benefit in preventing vision loss in eyes treated with triamcinolone acetonide over placebo, for patients with age-related macular degeneration.Triamcinolone acetonide is also administered via intralesional injection in the treatment of hypertrophic and keloid scars.Uncommonly, intramuscular injection of triamcinolone acetonide may be indicated for the control of severe or incapacitating allergic states for which conventional treatments have failed, such as asthma, atopic dermatitis, contact dermatitis, perennial or seasonal allergic rhinitis, serum sickness, and transfusion and drug hypersensitivity reactions. Contraindications
Evidence suggests that usage of triamcinolone acetonide or other steroids to treat macular edema increases the risk of increasing intraocular pressure in patients.Triamcinolone acetonide should not be used by those with tuberculosis or untreated fungal, bacterial, systemic viral or herpes simplex infections without consulting a doctor first. Pharmacology
Pharmacodynamics
Triamcinolone acetonide is a corticosteroid. It is specifically a glucocorticoid, or an agonist of the glucocorticoid receptor, that is about five times as potent as cortisol. It has very little mineralocorticoid effects. The affinities of triamcinolone acetonide for the androgen and estrogen receptors are both <0.1% (relative to testosterone and estradiol). However, triamcinolone acetonide has 15% of the affinity of progesterone for the progesterone receptor. In relation to this, triamcinolone acetonide can produce endocrine side effects like ovulation inhibition and menstrual irregularities.
