Randomized Controlled TrialBioavailability of two oral suspension and two oral tablet formulations of acyclovir 400 mg: two single-dose, open-label, randomized, two-period crossover comparisons in healthy Mexican adult subjects.
Acyclovir is an important antiviral drug, used extensively for treatment of herpes simplex and varicella zoster. Six oral generic formulations of acyclovir are available in Mexico; however, a literature search failed to identify data information concerning the bioavailability of these formulations in the Mexican population. ⋯ In these 2 studies in healthy subjects, single, 400-mg doses of the test brand of acyclovir administered either in tablet or suspension form, appeared to be bioequivalent to the reference brand based on the rate and extent of absorption in accordance with the definition of the US Food and Drug Administration. All formulations were well tolerated.

ReviewAdvancing therapy in type 2 diabetes mellitus with early, comprehensive progression from oral agents to insulin therapy.
Early and intensive glycemic control is necessary to prevent or minimize the development of microvascular and macrovascular complications in individuals with type 2 diabetes mellitus. However, many patients are unable to attain glycemic control, partly due to protracted treatment with oral antidiabetic drugs (OADs) despite inadequate control and barriers to initiating insulin therapy. Patients at different stages of disease may benefit from the early introduction of intensive glycemic control. ⋯ Based on the literature, early and persistent intensification of antidiabetic therapy is an approach that most likely will achieve optimal glycemic control in patients with type 2 diabetes and help prevent associated complications. Greater clinical experience with newer therapeutic approaches, including incretin mimetics and dipeptidyl peptidase-IV inhibitors, will provide insight into their place in the spectrum of diabetes treatments.

Comparative StudyComparison of hospitalizations, emergency department visits, and costs in a historical cohort of Texas Medicaid patients with chronic obstructive pulmonary disease, by initial medication regimen.
Limited information is available on the relative outcomes and treatment costs of various pharmacotherapies for chronic obstructive pulmonary disease (COPD) in a Medicaid population. ⋯ In this historical population of Texas Medicaid beneficiaries, the combination-therapy cohort was 27% less likely to have a COPD-related event than the ipratropium cohort, 10% less likely to have any all-cause event, had similar COPD-related costs, and had reduced all-cause costs. Thus, compared with the ipratropium cohort, the combination-therapy cohort had an improvement in outcomes (based on the decreased time to a hospitalization or ED visit), with similar or decreased direct medical costs. Future research is needed in other patient groups.
