Texacort
(hydrocortisone)Texacort Prescribing Information
Texacort Topical Solution 2.5% is indicated for the relief of the inflammatory and pruritic manifestations of corticosteroids-responsive dermatoses.
Topical corticosteroids are generally applied to the affected area as a thin film for three or four times daily depending on the severity of the condition.
Occlusive dressings may be used for the management of psoriasis or recalcitrant conditions.
If an infection develops, the use of occlusive dressings should be discontinued and appropriate antimicrobial therapy instituted.
Topical corticosteroids are contraindicated in those patients with a history of hypersensitivity to any of the components of the preparation.
The following local adverse reactions are reported infrequently with topical corticosteroids, but may occur more frequently with the use of occlusive dressings. These reactions are listed in an approximate decreasing order of occurrence: burning, itching, irritation, dryness, folliculitis, hypertrichosis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, maceration of the skin, secondary infection, skin atrophy, striae, miliaria.
Topical corticosteroids constitute a class of primarily synthetic steroids used as anti-inflammatory and antipruritic agents. Texacort Topical Solution contains hydrocortisone as the active corticosteroid, having the chemical formula of Pregn-4-ene-3, 20-dione, 11,17,21-trihydroxy-, (11 β)-. The molecular weight is 362.47. Its empirical formula is C 21H 30O 5and the structural formula is:
Each milliliter contains 25 mg of hydrocortisone (2.5% W/V) in a specially formulated vehicle containing alcohol (48.8% W/W), purified water, polysorbate 20 and isoceteth-20.
Topical corticosteroids share anti-inflammatory, antipruritic and vasoconstrictive actions.
The mechanisms of anti-inflammatory activity of the topical corticosteroids is unclear. Various laboratory methods, including vasoconstrictor assays, are used to compare and predict potencies and/or clinical efficacies of the topical corticosteroids. There is some evidence to suggest that a recognizable correlation exists between vasoconstrictor potency and therapeutic efficacy in man.
Pharmacokinetics
The extent of percutaneous absorption of topical corticosteroids is determined by many factors including the vehicle, the integrity of the epidermal barrier, and the use of occlusive dressings.
Topical corticosteroids can be absorbed from normal intact skin. Inflammation and/or other disease processes in the skin increase percutaneous absorption. Occlusive dressings substantially increase the percutaneous absorption of topical corticosteroids. Thus, occlusive dressings may be a valuable therapeutic adjunct for treatment of resistant dermatoses. (See DOSAGE AND ADMINISTRATION).
Once absorbed through the skin, topical corticosteroids are handled through pharmacokinetic pathways similar to systemically administered corticosteroids. Corticosteroids are bound to plasma proteins in varying degrees. Corticosteroids are metabolized primarily in the liver and are then excreted by kidneys. Some of the topical corticosteroids and their metabolites are also excreted into the bile.
