We compared the efficacy and adverse event rates of a new eye lubricant, OptiZen (InnoZen, Inc., polysorbate 80 0.5%) and Visine Original (Pfizer Consumer Healthcare, tetrahydrozoline HCl 0.05%). In this double-blind parallel arm trial, 50 healthy men and women, ages 18 to 65 years, with symptoms of CVS who use a video display terminal for a minimum of 4 hours per day were randomized to OptiZen (n = 25) or Visine Original (n= 25), 1 to 2 drops b.i.d. for 5 days. The primary end-points were ocular discomfort and adverse events. OptiZen and Visine Original had similar efficacy in alleviating symptoms of ocular discomfort (odds ratio of 1.23 [95% confidence interval, 0.63 to 2.42], P= 0.55). OptiZen and Visine Original were very similar with respect to odds ratios and 95% confidence interval (CI) for each of the measurement times (P= 0.72). Visine Original user...

Here we provide an extended follow-up to our earlier study to investigate the predictors of cognitive side effects (CSEs) and relative frequency of CSEs among all commonly used AEDs. In this retrospective study, medical records of 2860 adult outpatients with epilepsy seen at our center over a 12-year period who had taken one or more AEDs were examined. Of 2860 patients, 15% had intolerable CSEs attributed to at least one AED. On multiple logistic regression analysis, independent predictors of intolerable CSEs were lack of intellectual disability and polytherapy. In polytherapy, we found that intolerable CSEs were most commonly seen with topiramate (22.8% of 281 patients), significantly more than with almost all other AEDs. This was true in monotherapy as well, with significantly more intolerable CSEs occurring with topiramate (18.5% of 54 patients) than with gabapentin, carbamazepine, lamotrigine, and levetiracetam. AEDs with consistently low rates of ICSEs included gabapentin, pregabalin, lamotrigine, levetiracetam and carbamazepine. These data can help facilitate selection of AEDs.
