ReviewA new approach to glucose control in type 2 diabetes: the role of kidney sodium-glucose co-transporter 2 inhibition.
Hyperglycemia is a defining characteristic of type 2 diabetes mellitus and is a major risk factor associated with the development of many microvascular complications. There are numerous therapies currently available to treat hyperglycemia, but glycemic control rates remain poor. One potential reason is the decline in ß-cell function over time, which decreases the effectiveness of therapies that rely on insulin action. ⋯ Inhibition of SGLT2 is an attractive, insulin-independent target for increasing glucose excretion in the setting of hyperglycemia. A number of SGLT2 inhibitors have been synthesized, and results from preclinical studies have shown that they increase glucose excretion and normalize plasma glucose in diabetic models. Initial clinical data are promising and suggest that SGLT2 inhibitors may be a new therapeutic option for treating type 2 diabetes mellitus.

Randomized Controlled TrialClinical outcomes during opioid titration following initiation with or conversion to Remoxy®, an extended-release formulation of oxycodone.
Intra- and interpatient variability in opioid response usually necessitates opioid therapy titration to optimally balance analgesia and side effects, whether initiating therapy or converting from another opioid. Remoxy® (King Pharmaceuticals, Inc., Bristol, TN, which was acquired by Pfizer Inc in March 2011) is an extended-release formulation of oxycodone designed to maintain its rate-controlling mechanism following physical and chemical manipulation. A recent phase 3 trial, which required dose titration following initiation or conversion to Remoxy, demonstrated the long-term safety and efficacy of Remoxy in relieving moderate to severe chronic pain. ⋯ Of opioid-naïve patients, 300 (76%) reached a stable dose of Remoxy (mean, 2.2 titration steps), 253 (84%) of whom successfully initiated on Remoxy. Pain intensity decreased from baseline to study completion by approximately 35% for both opioid-experienced and opioid-naïve patients and adverse events were similar to those typically reported for opioids, with a higher incidence rate reported during titration (pre-stable dose period). These data provide important clinical information when initiating opioid-naïve patients on or converting opioid-experienced patients to Remoxy.
