Halog Solution
(halcinonide)Halog Solution Prescribing Information
HALOG SOLUTION (Halcinonide Topical Solution, USP) 0.1% is indicated for the relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses.
Apply HALOG SOLUTION (Halcinonide Topical Solution, USP) 0.1% to the affected area two to three times daily.
Occlusive Dressing Technique
Occlusive dressings may be used for the management of psoriasis or other recalcitrant conditions. Apply the solution to the lesion, cover with a pliable nonporous film, and seal the edges. If needed, additional moisture may be provided by covering the lesion with a dampened clean cotton cloth before the nonporous film is applied or by briefly wetting the affected area with water immediately prior to applying the medication. The frequency of changing dressings is best determined on an individual basis. It may be convenient to apply HALOG SOLUTION under an occlusive dressing in the evening and to remove the dressing in the morning (i.e., 12-hour occlusion). When utilizing the 12-hour occlusion regimen, additional solution should be applied, without occlusion, during the day. Reapplication is essential at each dressing change.
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 preparations.
The following local adverse reactions are reported infrequently with topical corticosteroids, but may occur more frequently with the use of occlusive dressings (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, and miliaria.
The topical corticosteroids constitute a class of primarily synthetic steroids used as anti-inflammatory and antipruritic agents. The steroids in this class include halcinonide. Halcinonide is designated chemically as 21-Chloro-9-fluoro-11β,16α‑, 17-trihydroxypregn- 4-ene-3,20-dione cyclic 16,17-acetal with acetone. Structural formula:
C 24H 32ClFO 5, MW 454.96, CAS-3093-35-4
Each mL of 0.1% HALOG SOLUTION (Halcinonide Topical Solution, USP) contains 1 mg halcinonide, edetate disodium, polyethylene glycol 300, and purified water with butylated hydroxytoluene as an antioxidant.
Topical corticosteroids share anti-inflammatory, antipruritic and vasoconstrictive actions.
The mechanism 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 the kidneys. Some of the topical corticosteroids and their metabolites are also excreted into the bile.
HALOG ®SOLUTION (Halcinonide Topical Solution, USP) 0.1% is supplied in plastic squeeze bottles containing, 60 mL (NDC 10631-095-20), and 120 mL (NDC 10631-095-10) of solution.
