Anti-seborrheic

Anti-seborrheics are drugs effective in seborrheic dermatitis (dandruff).[1] Selenium sulfide, zinc pyrithione, corticosteroids, imidazole antifungals, and salicylic acid are common anti-seborrheics.

Ideal anti-seborrheic

An ideal antiseborrheic should have the following qualities:

Specific anti-seborrheic agents

Selenium sulfide

Selenium sulfide slows down epidermal proliferation. It is fungicidal to Pityrosporum ovale. It also acts as an anti-keratolytic. Selenium sulfide is also known to reduce dryness of scalp and folliculitis.[2] It is to be noted that systemic toxicity can appear if it is applied to inflamed skin. Hypersensitivity reactions are noted in some people.

Zinc pyrithione

Like selenium sulfide, zinc pyrithione also reduces epidermal turnover and inhibits fungal growth.[3] It is often administered with ketoconazole for better results. The symptoms do not resolve completely even after prolonged medication.

Corticosteroids

Main article: Corticosteroid

Topical steroids are used to relieve the symptoms of seborrheic dermatitis. It has a fungicial action, and reduces dandruff.[4] The disadvantage is that it has a high relapse rate on discontinuation. Prolonged use can cause poor healing of wounds.

Imidazole antifungals

Only a few imidazole antifungals are effective against seborrheic dermatitis. Ketoconazole was found to be the most active against Pityrosporum ovale. It is available in both oral and topical formulations. It is also available as cream, gel and tablet. Unlike other drugs, it does not cause skin irritation or phototoxicity. Clotrimazole is also used in treating seborrhoea.

Other drugs

Other drugs like sulfur and resorcinol have also been found useful in treating seborrheic dermatitis. These drugs have keratolytic and antiseptic properties which may benefit seborrhoea. Salicylic acid has a mild effect on seborrhoea.
