Drug News

Research Results

In an article published in the June issue of the Journal of the Federation of American Societies for Experimental Biology* scientists reported that dithranol, which is used for the treatment of severe psoriasis, induces keratinocyte apoptosis through a novel mitochondrial pathway dependent on oxidative respiration and involving electron transfer with the ubiquinone pool. They suggested that this could be a potentially important mechanism involved in the clearance of psoriasis.*

Insect Repellant

According to a recent report in The Medical Letter*, Picaridin (KBR 3023) became available in June 2005 in the US as a 7% solution (Cutter Advanced®, Spectrum Brands). Picaridin has been used as an insect repellant for years in Europe and Australia, where no serious toxicity has been reported. The US Centers for Disease Control and Prevention is recommending it as an alternative to DEET. Repellants containing picaridin are not registered for use in Canada.

Drug Warning

Skin Cap® (Cheminova Laboratories International SA) is a product made in Madrid, Spain that was sold in the US in the mid-1990s. Its active ingredients were reported to be pyrithione zinc and sodium lauryl sulfate. However, analysis of two lots of this product demonstrated that it also contained clobetasol propionate. In 1997, the US FDA stopped its importation into the US. In 2004, a sample purchased over the internet was again analyzed showing adulteration with highpotency glucocorticosteroids.*
