Misuse of prescription medicines is as prevalent as the use of recreational drugs and novel psychoactive substances in Singapore: an unrecognised public health issue?
CONCLUSION: Misuse of prescription medicine in Singapore was common, with prevalence comparable to the use of recreational drugs/NPS. A common source for misused drugs was physicians. Further studies are required to determine whether this is more widespread in Singapore and establish the different forms of drug diversion, so that appropriate prevention strategies can be implemented.

Tolerance and dependence following chronic alprazolam treatment: quantitative observation studies in female rhesus monkeys
ConclusionsChronic alprazolam treatment resulted in rapid tolerance to some behaviors (e.g., deep sedation) but no tolerance to others (e.g., rest/sleep posture). Physical dependence was observed via both spontaneous and precipitated withdrawal. Based on previous research, these phenomena may reflect differential plasticity at GABAA receptor subtypes.

Reducing Inappropriate Drug Use in Older Patients by Use of Clinical Decision Support in Community Pharmacy: A Mixed-Methods Evaluation
ConclusionWhen community pharmacists implemented CDSS alerts to reduce inappropriate drug use in older patients, they registered a persistent drug therapy change in 8.7% of the cases. Alerts triggered by a first prescription were two times more likely to be associated with a persistent drug therapy change than alerts triggered by repeat prescriptions. This study found that clinical rules can be used to detect inappropriate drug use in older patients and that drug therapy can change based on the alerts. This suggests that CDSS alerts are a useful tool for implementing guidelines on PIM in older patients in daily practice. (...

Benzodiazepine Use Is Associated With an Increased Risk of Neurocognitive Impairment in People Living With HIV
Discussion: BZD use may elevate risk for NCI in PLWH, potentially through diffuse neurocognitive slowing and acute compromise of recall and higher-order capacities. These effects are robust to psychosocial and HIV-specific factors and occur in comparison with a tightly matched BZD− group. Prospective and interventional studies should evaluate causal associations between NCI and BZD use and explore treatment alternatives to BZDs in PLWH.

GABAA/benzodiazepine receptors in the dorsal periaqueductal gray mediate the panicolytic but not the anxiolytic effect of alprazolam in rats.
Abstract Although the etiology of panic disorder (PD) remains elusive, accumulating evidence suggests a key role for the dorsal periaqueductal gray matter (dPAG). There is also evidence that this midbrain area is critically involved in mediation of the panicolytic effect of antidepressants, which with high potency benzodiazepines (e.g. alprazolam and clonazepam) are first line treatment for PD. Whether the dPAG is also implicated in the antipanic effect of the latter drugs is, however, still unknown. We here investigated the consequences of blocking GABAA or benzodiazepine receptors within the dPAG, with bicuculli...

Development of a Novel LC- MS/MS Method for Detection and Quantification of Tramadol Hydrochloride in Presence of Some Mislabeled Drugs: Application to Counterfeit Study.
Abstract Counterfeiting of pharmaceuticals has become a serious problem all over the world particularly in the developing countries. In the present work, a highly sensitive LC-MS/MS method was developed for simultaneous determination of tramadol hydrochloride (TRM) in presence of some previously expected mislabeled drugs such as alprazolam (ALP), diazepam (DIZ), chlorpheniramine maleate (CHR), diphenylhydramine (DIP) and paracetamol (PAR). The prepared samples were analyzed on API 4000 mass spectrometer using Eclipse C18 column (3.5 μm, 4.6× 100 mm). The mobile phase consisting of 0.01% formic acid, aceto...

Urine Drug Tests: Ordering and Interpreting Results.
Abstract Urine drug testing is an essential component of monitoring patients who are receiving long-term opioid therapy, and it has been suggested for patients receiving long-term benzodiazepine or stimulant therapy. Family physicians should be familiar with the characteristics and capabilities of screening and confirmatory drug tests. Immunoassays are qualitative tests used for initial screening of urine samples. They can give false-positive and false-negative results, so all results are considered presumptive until confirmatory testing is performed. Immunoassays for opioids may not detect commonly prescribed sem...
