Dosage

Children: For children, the use of clobetasol should be guided by a healthcare professional, with consideration for the child's age, weight, and specific skin condition. Refer to the BNF for Children for detailed dosing recommendations.

Adults: For adults, clobetasol is typically applied to the affected area once or twice daily, depending on the specific formulation and severity of the condition. It is important to follow specific guidance from a healthcare professional.

Mechanism of action

Clobetasol exerts its effects by binding to the glucocorticoid receptor, leading to the regulation of gene expression. This results in the inhibition of pro-inflammatory cytokines and chemokines, suppression of inflammatory cell infiltration, and reduction of immune responses. The drug also stabilizes lysosomal membranes, preventing the release of enzymes that can cause tissue damage.

Pharmacodynamics

Clobetasol has a high affinity for the glucocorticoid receptor, making it one of the most potent corticosteroids available. Its anti-inflammatory effects help decrease redness, swelling, and itching associated with dermatologic conditions. The drug's potency allows for effective treatment of severe skin conditions with minimal doses, reducing the risk of systemic absorption and side effects.

Pharmacokinetics

Clobetasol is well-absorbed through the skin, with systemic absorption depending on the vehicle used and the condition of the skin. Once absorbed, it is metabolized mainly in the liver, and its metabolites are excreted in urine. The half-life of clobetasol is variable, but it is typically eliminated quickly from the body due to its extensive first-pass metabolism.

Contra-indications

• Hypersensitivity to clobetasol or any of its excipients
• Untreated bacterial, viral, or fungal infections

• Perioral dermatitis

Adverse effects

• Skin atrophy
• Striae
• Telangiectasia
• Systemic absorption leading to adrenal suppression
• Hypopigmentation
• Allergic contact dermatitis
• Burning, itching, or irritation at the application site

Interactions

• Concurrent use with other topical corticosteroids may enhance effects and increase risk of systemic effects
• Potential interactions with drugs that affect the metabolism of corticosteroids

Precautions

• Use with caution in patients with a history of adrenal insufficiency
• Avoid prolonged use especially in children and on large surface areas
• Monitor for signs of systemic absorption, especially in high-potency formulations
• Avoid contact with eyes and mucous membranes

Pregnancy

Clobetasol should be used in pregnancy only if the benefits outweigh the risks. Long-term use or application over large areas should be avoided.

Breast-feeding

Clobetasol can be used while breastfeeding, but caution should be exercised. The smallest effective dose should be used for the shortest duration necessary.
