Post-herpetic neuralgia: 5% lidocaine medicated plaster, pregabalin, or a combination of both?
Although this open-label study is lacking a placebo control group, the results suggest that 5% lidocaine medicated plaster is at least as effective as pregabalin for pain relief in PHN, with a favourable safety profile and a resulting positive benefit-risk ratio. In patients unresponsive to either monotherapy, combination therapy provides additional efficacy and is well-tolerated.
The relationship in sevelamer-resistant dialysis patients between the reduction of serum PO(4), induced by the chitosan-loaded chewing gum, and CRP reduction supports also in humans a proinflammatory role of hyperphosphatemia "per se" derived from "in vitro" studies. This further contributes to the high cardiovascular risk of ESRD patients making their serum phosphate in the normal range of vital importance.
