Flurandrenolide

INDICATIONS AND USAGE Flurandrenolide Lotion USP, 0.05% is indicated for the relief of the inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses.

CLINICAL PHARMACOLOGY Flurandrenolide Lotion USP, 0.05% is primarily effective because of its anti-inflammatory, antipruritic, and vasoconstrictive actions. The mechanism of the anti-inflammatory effect of topical corticosteroids is not completely understood. 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. Corticosteroids with anti-inflammatory activity may stabilize cellular and lysosomal membranes. There is also the suggestion that the effect on the membranes of lysosomes prevents the release of proteolytic enzymes and, thus, plays a part in reducing inflammation. Evaporation of water from the lotion vehicle produces a cooling effect, which is often desirable in the treatment of acutely inflamed or weeping lesions. 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. Once absorbed through the skin, topical corticosteroids are handled through pharmacokinetic pathways similar to those of systemically administered corticosteroids. Corticosteroids are bound to plasma proteins in varying degrees. They are metabolized primarily in the liver and then excreted in the kidneys. Some of the topical corticosteroids and their metabolites are also excreted into the bile.

DOSAGE AND ADMINISTRATION Shake well before using. A small quantity of Flurandrenolide Lotion USP, 0.05% should be rubbed gently into the affected area 2 or 3 times daily. Therapy should be discontinued when control is achieved. If no improvement is seen within 2 weeks, reassessment of the diagnosis may be necessary. Flurandrenolide Lotion USP, 0.05% should not be used with occlusive dressings unless directed by a physician. Tight-fitting diapers or plastic pants may constitute occlusive dressings.

ADVERSE REACTIONS 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 The following may occur more frequently with occlusive dressings: Maceration of the skin Secondary infection Skin atrophy Striae Miliaria Postmarketing Adverse Reactions The following adverse reactions have been identified during post approval use of flurandrenolide lotion. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Skin : skin striae, hypersensitivity, skin atrophy, contact dermatitis, and skin discoloration.

CONTRAINDICATIONS Topical corticosteroids are contraindicated in patients with a history of hypersensitivity to any of the components of these preparations.

OVERDOSAGE Topically applied corticosteroids can be absorbed in sufficient amounts to produce systemic effects ( see PRECAUTIONS ).
