Abstract
Prescription with more than one drug increases the risk of drug-drug interaction (D-DI), therapeutic failure, high pharmacological effect, or adverse events. The objectives of this study were to estimate the frequency of potential drug-drug interactions in prescriptions for hospitalized patients, and...

Abstract
Randomized evidence from clinical trials and naturalistic evidence collected from pharmacoepidemiology and pharmacovigilance activities both contribute to the initial and continuous assessment of the benefits and risks of a drug, ie, the balance between therapeutic efficacy and safety risks. Benefit-...

Abstract
We provide examples of how these databases have been used for descriptive drug utilization studies and analytical pharmacoepidemiological studies linking drug exposure to other health registries. Comparisons are facilitated by many similarities among the databases, including data source, content, co...

Abstract
Optimizing medication use through the evaluation of Potentially Inappropriate Medications (PIMs) has been the focus of a great deal of research. The Centers for Medicare & Medicaid Services (CMS) has created its own definition of PIMs from a variety of existing criteria and has contracted with each...

Abstract
Rare diseases attract very little interest for drug development. To create more favourable conditions, incentives for development (scientific advice, research grants) and marketing of medicines (market exclusivity, regulatory fee reductions) are offered by several orphan legislations. These incentiv...

Abstract
Variability in cardiovascular drugs is of great interest because of its high population use, its high expenditure and the availability of strong evidence supporting its use. The aim of this study is to describe variation in dispensation, price and pharmaceutical expenditure for 11 subgroups of cardi...

Knowledge about safe medication use during pregnancy is limited, yet about two of every three women take at least one prescription medication during pregnancy, furthermore, there is a lack of rigorous studies evaluating birth outcomes associated with in utero exposure to medications. The Medication...

Abstract
We propose a comprehensive mechanistic classification of adverse drug effects that considers five elements: the Extrinsic chemical species (E) that initiates the effect; the Intrinsic chemical species (I) that it affects; the Distribution (D) of these species in the body; the (physiological or patho...

Abstract
In total, 20 randomised controlled trials (RCTs) were included in this assessment, mostly of 12-18 weeks duration and comparing one of the technologies added to supportive treatment with supportive treatment alone. Four published economic evaluations were identified. None produced results generalisa...

Abstract
We concluded that the age may be considered a methodological bias in the presentation of data. Therefore we calculated AED utilization as the age-adjusted prevalence rates (per/1000 inhabitants). For the most commonly prescribed AEDs they were: BARB 1.8 (95% CI 1.6-2.0), CBZ 1.9 (95% CI 1.7-2.1), VP...

There were 106,074 births, 1527 ectopic pregnancies and 25,180 terminations of pregnancy. Dispensed medicines were linked to 28.0% of the pregnancy events. Multiple birth pregnancies were 50% more likely to be dispensed a medicine in the first trimester. As parity increased, so did the likelihood of...

Compared to non-use, the OR of prostate cancer for ever-use of warfarin in the preceding 5 years was 0.91 (95%CI: 0.81-1.02) (without "black-hole") and 0.89 (95%CI: 0.79-1.01) (with "black-hole"). Compared to non-use, cumulative use of 1, 2, 3, and 4 years were associated with ORs of 1.02, 0.94, 0.7...
