Randomized Controlled Trial Comparative StudyA randomized, double-blind, 8-week crossover study of once-daily controlled-release tramadol versus immediate-release tramadol taken as needed for chronic noncancer pain.
The purpose of this study was to evaluate the efficacy of controlled-release (CR) tramadol and immediate-release (IR) tramadol in patients with moderate or greater intensity chronic noncancer pain. ⋯ This study reports significant improvement in pain intensity with CR tramadol as compared with IR tramadol.

ReviewPregabalin: a novel gamma-aminobutyric acid analogue in the treatment of neuropathic pain, partial-onset seizures, and anxiety disorders.
The US Food and Drug Administration (FDA) approved pregabalin in December 2004 for the treatment of neuropathic pain associated with diabetic peripheral neuropathy and postherpetic neuralgia. Pregabalin is the first drug approved in the United States and in Europe for both conditions. In June 2005, pregabalin was approved as an adjunctive treatment in adults with partial-onset seizures. The FDA currently is considering the approval of pregabalin as adjunctive therapy in adults with generalized anxiety disorder (GAD) or social anxiety disorder (SAD). ⋯ Pregabalin appears to be an effective therapy in patients with diabetic peripheral neuropathy, postherpetic neuralgia, and adults with refractory partial-onset seizures. The available data suggest that pregabalin may be beneficial as an adjunctive therapy in adult patients with GAD or SAD.

Randomized Controlled TrialPost hoc analysis of a randomized, double-blind, placebo-controlled efficacy and tolerability study of tramadol extended release for the treatment of osteoarthritis pain in geriatric patients.
Once-daily tramadol extended release (ER) was evaluated for 12 weeks in a randomized, double-blind, placebo-controlled, parallel-group study in 1020 patients with osteoarthritis of the knee or hip. As previously reported, compared with placebo, the results of the study showed that patients treated with tramadol ER had significant improvement in the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index and in pain-related sleep parameters. ⋯ This post hoc analysis suggests that the tramadol ER 300-mg dose was associated with statistically significant improvement in pain intensity and physical function, and for most of the pain-related sleep effects among these geriatric patients with moderate chronic/persistent pain.

Randomized Controlled TrialResults of the glucose-lowering effect of WelChol study (GLOWS): a randomized, double-blind, placebo-controlled pilot study evaluating the effect of colesevelam hydrochloride on glycemic control in subjects with type 2 diabetes.
This study evaluated the glycosylated hemoglobin (HbA(1c)-lowering effect of colesevelam hydrochloride, a bile acid sequestrant, in subjects with type 2 diabetes that was inadequately controlled by existing antihyperglycemic therapy. ⋯ In these subjects with type 2 diabetes, 12 weeks of colesevelam treatment were associated with significant reductions in HbA(1c) and in fructosamine and postprandial glucose levels compared with placebo. The 2 groups had a similar adverse-event profile, with the exception of an increased incidence of constipation in the colesevelam group. These results suggest that colesevelam may improve both lipid control and glycemic control in patients with type 2 diabetes receiving oral antihyperglycemic medications.

Prevalence, utilization patterns, and predictors of antipsychotic polypharmacy: experience in a multistate Medicaid population, 1998-2003.
This study was conducted to estimate the prevalence of antipsychotic polypharmacy among fee-for service state Medicaid beneficiaries initiating antipsychotic drug therapy and to investigate psychiatric and demographic predictors of such polypharmacy. ⋯ In these fee-for-service Medicaid beneficiaries from 5 states, the prevalence of chronic antipsychotic polypharmacy was low in the year after the initiation of therapy. Polypharmacy was more common in patients with indicators of more severe mental illness.
