FDA Issues Warning About Antiseizure Drug Potiga

Neurologists and other physicians using the antiseizure drug (ezogabine (Potiga, Valeant Pharmaceuticals) as an adjunct treatment in patients with partial-onset epilepsy should be on the lookout for blue skin discoloration and retinal abnormalities and report these adverse effects should they occur.

The Food and Drug Administration (FDA) has issued a warning that ezogabine can cause pigment changes and eye abnormalities. According to a government press release, it's not known at this time whether these changes are reversible. The FDA said it is working with the manufacturer to gather and evaluate all available information to better understand these developments and will update the public when more information is available.

The FDA recommends that all patients taking ezogabine have a baseline eye examination and periodic eye examinations that should include visual acuity testing and dilated fundus photography. Periodic examinations may include fluorescein angiography, ocular coherence tomography, perimetry, and electroretinography.

Novel Agent Safe, Effective for Parkinson's Psychosis

San Diego, California — A novel, first-in-class, nondopaminergic agent that selectively blocks serotonin 5-HT2A is safe and effective for the treatment of Parkinson's disease psychosis (PDP), new research suggests.

Confirming previously released topline results and reported byMedscape Medical News at that time, the phase 3 placebo-controlled trial showed that the selective nondopaminergic 5-HT2A receptor agonist pimavanserin was significantly better than placebo at reducing PDP.
