Examining Time to Initiation of Biologic Disease-modifying Antirheumatic Drugs and Medication Adherence and Persistence Among Texas Medicaid Recipients With Rheumatoid Arthritis.
Little is known about the transition from nonbiologic disease-modifying antirheumatic drugs (DMARDs) to biologic DMARDs or about individual nonbiologic DMARD use patterns among patients with rheumatoid arthritis (RA). This study examined time to initiation of biologic DMARDs and nonbiologic DMARD medication adherence and persistence among Texas Medicaid recipients with RA taking nonbiologic DMARDs. ⋯ These results should be interpreted in light of some study limitations, such as using proportion of days covered as a proxy for adherence, not having clinical data to control for RA severity, and lack of generalizability to all US populations. Given the study findings, both clinicians and other decision makers may want to investigate the potential driving factors of initiation of biologic DMARDs to provide effective RA management and consider patient education programs to enhance medication adherence and persistence to RA medications.

Impact of an Antimicrobial Stewardship Program on Patient Safety in Veterans Prescribed Vancomycin.
This study aimed to determine the safety impact of an antimicrobial stewardship program (ASP) on vancomycin-associated nephrotoxicity and to examine risk factors contributing to the development of toxicity. ⋯ ASPs represent an important aspect of a patient-safety initiative in order to reduce vancomycin-associated nephrotoxicity. Concurrent piperacillin/tazobactam therapy, surgical service, and elevated maximum trough concentration were risk factors for nephrotoxicity.

Randomized Controlled TrialEvaluation of the Pharmacokinetics of Single- and Multiple-dose Buprenorphine Buccal Film in Healthy Volunteers.
Buprenorphine, a partial μ-receptor agonist, is approved for the management of moderate to severe pain, but it has low oral bioavailability. Two open-label studies were performed to determine the pharmacokinetic profile of buprenorphine from buccal film formulations of buprenorphine. ⋯ The absolute bioavailability of BBUP was 46% to 51% across a 16-fold dose range, with dose-proportional increases in systemic exposure. Apparent steady-state conditions occurred within 3 days of dosing. These pharmacokinetic results suggest that therapeutic buprenorphine plasma concentrations can be obtained with BBUP across a wide dose range in a shorter time than other (eg, transdermal) dosage forms.

Pharmacokinetic Profile and Sustained 24-hour Analgesia of a Once-daily Hydrocodone Bitartrate Extended-release Tablet with Abuse-deterrent Properties.
The purpose of this study was to evaluate the pharmacokinetics (PK) and 24-hour analgesic effectiveness of once-daily, single-entity, extended-release hydrocodone (HYD) with abuse-deterrent properties. ⋯ Once-daily HYD exhibits linear, dose-proportional PK properties and is associated with a lower variability in plasma hydrocodone concentrations when compared with an immediate-release hydrocodone combination product. Notably, analgesia provided by HYD is sustained during the 24-hour dosing interval. ClinicalTrials.gov identifier: NCT01400139 (Study 4).

Restless legs syndrome (RLS) is a commonly occurring neurologic disorder that affects up to one third of women during pregnancy. RLS has been associated with increased sympathetic tone in the nonpregnant population. We examined whether a RLS surrogate is associated with a higher prevalence of pregnancy and neonatal outcomes. ⋯ A higher frequency of jumpy or jerky leg symptoms, a proxy for RLS during pregnancy, was associated with a higher likelihood of gestational hypertensive disorders and neonatal outcomes such as gestational age at birth and birth weight. These findings may affect RLS treatment decisions during pregnancy.
