Background

Dipyrithione, a bactericidal and fungicidal pyrithione derivate, was formulated as Crimanex anti-dandruff shampoo, but is no longer available.6 It is currently used as a pesticide, and not used in any FDA approved drug products.3

Interestingly, dipyrithione has been studied and shown to have cytotoxic and potent broad-spectrum antitumor activity, which suggests a potential basis for an anticancer drug development.1

Pyrithione derivatives, such as Pyrithione and sodium pyrithione, are widely used as cosmetic preservatives and as anti-dandruff agents in shampoos.1 It may be combined with other ingredients, such as triclosan to serve as antifungal and antibacterial skin treatments.9

Dandruff is a common scalp disease affecting >40% of the world's adult population, and may be caused by fungi such as Malassezia globosa and M. restricta.4
