ReviewFospropofol disodium, a water-soluble prodrug of the intravenous anesthetic propofol (2,6-diisopropylphenol).
Today, propofol or 2,6-diisopropylphenol is the anesthetic mainly used for monitored anesthetic care sedation and during intravenous anesthesia. The formulation, a lipid macroemulsion, shows several disadvantages. Therefore, during the past years considerable scientific effort has been undertaken to find either a better formulation or a prodrug of propofol. Fospropofol is the first propofol prodrug that has been intensively studied in man. It has been licensed in 2008 by the FDA for monitored anesthetic care sedation. ⋯ As the impact of an errorness drug assay for propofol liberated from fospropofol is not exactly defined, no clear conclusions can be drawn from the first published pharmacokinetic/pharmacodynamic studies. Fospropofol was well tolerated in the first two clinical studies and no serious side effects were reported. After characterization of the true pharmacokinetic/pharmacodynamics profile, fospropofol, an aqueous solution, has the potential to favorably compare with benzodiazepines for procedural sedation and also may be used for long-term sedation and intravenous anesthesia.

ReviewCurrent progress in the pharmacological therapy of fibromyalgia.
Fibromyalgia (FM) is a chronic musculoskeletal pain disorder often associated with fatigue, dyscognition, and sleep disturbances. Recent research advances highlight a critical role for aberrant central pain processing in FM, and, consistent with these data, the first three drugs approved by the FDA for FM over the past 2 years have a predominantly central mode of action. ⋯ The serotonin-norepinephrine reuptake inhibitors duloxetine and milnacipran have been approved more recently and are believed to reduce pain by increasing serotonin and norepinephrine concentrations in descending inhibitory pain pathways. Agents with multiple other mechanisms of action are in development and promise an assortment of therapeutic options for this complex disorder in the near future.
