Randomized Controlled Trial Multicenter StudyPost hoc comparison of daily rates of nausea and vomiting with once- and twice-daily galantamine from a double-blind, placebo-controlled, parallel-group, 6-month study.
A once-daily extended-release galantamine(GAL-ER) formulation has been designed to improve tolerability compared with twice-daily immediate-release galantamine (GAL-IR). ⋯ In these subjects with AD, the daily percentage of subjects reporting nausea and vomiting, and the percentage of days with vomiting among subjects reporting vomiting, did not significantly differ between the GAL-ER and GAL-IR groups. However, GAL-ER was associated with a significantly lower percentage of days with nausea than GAL-IR among subjects reporting nausea. AUC of the daily percentage of subjects with nausea or vomiting during dose titration did not differ significantly between the GAL-ER and placebo groups but was significantly higher in the GAL-IR group than placebo. Subjects with nausea or vomiting who received GAL-ER reported significantly less antiemetic use than those treated with GAL-IR. These results suggest the need for additional studies to explore the potential differences in the tolerability of these formulations.

Randomized Controlled Trial Multicenter StudyEfficacy and safety of mixed amphetamine salts extended release (adderall XR) in the management of oppositional defiant disorder with or without comorbid attention-deficit/hyperactivity disorder in school-aged children and adolescents: A 4-week, multicenter, randomized, double-blind, parallel-group, placebo-controlled, forced-dose-escalation study.
Oppositional defiant disorder (ODD)is associated with a high degree of impairment in social skills, family interaction, and academic functioning. Comorbid ODD is reportedly present in 40% to 70% of children and adolescents with attention-deficit/hyperactivity disorder (ADHD). ⋯ This study found that higher doses ofMAS XR (30 and 40 mg) were effective and well tolerated in the management of ODD in these school aged children and adolescents in the presence or absence of ADHD.

Randomized Controlled Trial Multicenter StudyA multicenter, randomized, double-blind, active-comparator, placebo-controlled, parallel-group comparison of the incidence of endoscopic gastric and duodenal ulcer rates with valdecoxib or naproxen in healthy subjects aged 65 to 75 years.
Compared with nonselective NSAIDs, cyclooxygenase (COX)-2-selective inhibitors have been associated with a lower incidence of gastroduodenal ulcers (in short-term endoscopic studies) and ulcer complications (in long-term trials). ⋯ In these healthy older subjects (aged 65-75 years), valdecoxib 20 mg BID was associated with a significantly lower rate of gastroduodenal, gastric, and duodenal ulcers than naproxen 500 mg BID, even after 6.5 days of therapy.

Prevalence of inadequate glycemic control among patients with type 2 diabetes in the United Kingdom general practice research database: A series of retrospective analyses of data from 1998 through 2002.
Since the mid-1990s, the development of new oral antidiabetic agents (OAs) and treatment guidelines have created an opportunity to improve glycemic control in patients with type 2 diabetes. ⋯ Despite the introduction of new OAs and treatment guidelines, the prevalence of inadequate glycemic control remains high (>60%) in patients with type 2 diabetes in the United Kingdom. Regardless of the HbA1c cutoff, patients with inadequate control were younger and received prescriptions for more OAs than patients with good control.

Case ReportsMetformin-associated lactic acidosis treated with continuous renal replacement therapy.
Lactic acidosis is an infrequent complication of metformin therapy for diabetes mellitus. The presence of clinical conditions, such as renal failure, increases the risk of metformin-associated lactic acidosis (MALA). We present a case of lactic acidosis in a patient with diabetes treated with metformin, complicated by acute renal failure in preexisting chronic nephropathy. ⋯ MALA should be strongly suspected in diabetic patients presenting with high anion gap metabolic acidosis and increased serum lactate level. In the case described, prompt recognition of lactic acidosis and early application of bicarbonate-buffered CVVHDF produced successful results.
