Alcortin A Gel - Clinical Pharmacology
Hydrocortisone Acetate has anti-inflammatory, antipruritic and vasoconstrictive properties. While the mechanism of anti-inflammatory activity is unclear, there is evidence to suggest that a recognizable correlation exists between vasoconstrictor potency and therapeutic efficacy in humans. Iodoquinol has both antifungal and antibacterial properties.
The extent of percutaneous absorption of topical steroids is determined by many factors including the vehicle, the integrity of the epidermal barrier and the use of occlusive dressings. Hydrocortisone Acetate can be absorbed from normal intact skin. Inflammation and/or other inflammatory disease processes in the skin increase percutaneous absorption. Occlusive dressings substantially increase the percutaneous absorption of topical corticosteroids. Once absorbed through the skin, Hydrocortisone Acetate is metabolized in the liver and most body tissue to hydrogenated and degraded forms such as tetrahydrocortisone and tetrahydrocortisol. These are excreted in the urine, mainly conjugated as glucuronides, together with a very small proportion of unchanged Hydrocortisone Acetate. There are no data available regarding the percutaneous absorption of Iodoquinol; however, following oral administration, 3-5% of the dose was recovered in the urine as a glucuronide.
ALCORTIN A is contraindicated in those patients with a history of hypersensitivity to Hydrocortisone Acetate, Iodoquinol, aloe vera, glycine, histidine, lysine, palmitic acid, or any other components of the preparation.
Warnings and Precautions
For external use only. Keep away from eyes. If irritation develops, the use of ALCORTIN A should be discontinued and appropriate therapy instituted. Staining of the skin, hair, and fabrics may occur. Not intended for use on infants or under diapers or occlusive dressings. If extensive areas are treated or if the occlusive dressing technique is used, the possibility exists of increased systemic absorption of the corticosteroid, and suitable precautions should be taken. Children may absorb proportionally larger amounts of topical corticosteroids and thus be more susceptible to systemic toxicity. Parents of pediatric patients should be advised not to use tight-fitting diapers or plastic pants on a child being treated in the diaper area, as these garments may constitute occlusive dressings. Iodoquinol may be absorbed through the skin and interfere with thyroid function tests. If such tests are contemplated, wait at least one month after discontinuance of therapy to perform these tests. The ferric chloride test for phenylketonuria (PKU) can yield a false positive result if Iodoquinol is present in the diaper or urine. Prolonged use may result in overgrowth of non-susceptible organisms requiring appropriate therapy. Keep out of reach of children. Burning, itching, irritation and dryness have been reported infrequently following the use of topical corticosteroids.
Carcinogenesis, Mutagenesis and Impairment of Fertility:
Long-term animal studies have not been performed to evaluate the carcinogenic potential of the effect on fertility of Hydrocortisone Acetate or Iodoquinol. In vitro studies to determine mutagenicity with Hydrocortisone Acetate have revealed negative results. Mutagenicity studies have not been performed with Iodoquinol.
Pregnancy Category C:
Animal reproductive studies have not been conducted with ALCORTIN A. It is not known whether ALCORTIN A can cause fetal harm when administered to pregnant women or can affect reproductive capacity. ALCORTIN A should be given to pregnant women only if clearly needed.
It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when ALCORTIN A is administered to a nursing woman.
Safety and effectiveness in pediatric patients under the age of 12 have not been established.
The following local adverse reactions are reported infrequently with topical corticosteroids. 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 infections, skin atrophy, striae and miliaria. Possible local adverse reactions associated with topical iodoquinol include burning, itching, irritation, and dryness.
Store at 20°C to 25°C (68°F to 77°F), excursions permitted between 15°C and 30°C (between 59°F and 86°F). Brief exposure to temperatures up to 40°C (104°F) may be tolerated provided the mean kinetic temperature does not exceed 25°C (77°F); however, such exposure should be minimized.
