Although economic theory indicates that it should not be necessary to intervene in the generic drug market through price regulation, most EU countries intervene in this market, both by regulating the maximum sale price of generics (price cap) and by setting the maximum reimbursement rate, especially by means of reference pricing systems. We analyse current knowledge of the impact of direct price-cap regulation of generic drugs and the implementation of systems regulating the reimbursement rate, particularly through reference pricing and similar tools, on dynamic price competition between generic competitors in Europe. A literature search was carried out in the EconLit and PubMed databases, and on Google Scholar. ⋯ Beyond the price reduction forced by the price-cap and/or reference pricing regulation itself, the entry of new generic competitors is useful for lowering the real transaction price of purchases made by pharmacies (dynamic price competition at ex-factory level), although this effect is weaker or non-significant for official ex-factory prices and consumer prices in some countries. When maximum reimbursement systems such as reference pricing or similar types are applied, pharmacies are seen to receive large discounts on the price they pay for the pharmaceuticals, although these discounts are not transferred to the consumer price. The percentage discount offered to pharmacies in a country that uses a price-cap system combined with reference pricing is positively and significantly related to the number of generic competitors in the market for the pharmaceutical (dynamic price competition at ex-factory level).

The SENIORS trial demonstrated that nebivolol is effective in the treatment of heart failure in elderly patients (e.g. > or = 70 years). This analysis evaluates the cost effectiveness of nebivolol compared with standard treatment. ⋯ This analysis indicates that nebivolol appears to be a cost-effective treatment for elderly patients with heart failure compared with standard care.

The objective of this review was to describe the performance of health-utility measures in valuing the quality-of-life (QOL) impact of changes in osteoarthritis (OA)-related chronic pain when administered within a clinical trial setting. Because the collection of utility data within a clinical trial is not always feasible in the development of health economic models, utility data from prior non-randomised studies conducted among patients with OA were also summarized. We conducted a literature review using the MEDLINE, EMBASE and PsycINFO databases. ⋯ Finally, the body of clinical trial-based utility literature in OA was found to be relatively modest, with considerably more observational studies collecting utility data. Based on the limited number of trial-based health-utility evaluations in OA to date, there can potentially be divergent findings with respect to clinical and statistical significance of changes in utility measures and corresponding measures of health status. Analysts should carefully evaluate issues of statistical power and clinical sensitivity in utilizing these measures in clinical trials of OA interventions.

Randomized Controlled Trial Multicenter Study
Escitalopram and duloxetine in major depressive disorder: a pharmacoeconomic comparison using UK cost data.
Selective serotonin reuptake inhibitors (SSRIs) and serotonin-noradrenaline reuptake inhibitors (SNRIs) are approved for the treatment of major depressive disorder (MDD). The allosteric SSRI escitalopram has been shown to be at least as clinically effective as the SNRIs venlafaxine and duloxetine in MDD, with a better tolerability profile. In addition, escitalopram has been shown to be cost saving compared with venlafaxine. ⋯ Escitalopram was associated with significantly lower duration of sick leave and significant savings in the total cost compared with duloxetine; it dominated duloxetine when effectiveness was assessed on the SDS scale. Indirect costs due to sick leave accounted for the most substantial portion of the total cost and should, therefore, be an important consideration when pharmacoeconomic comparisons between treatments are made from the societal perspective. The link between decrease in absenteeism and early (8-week) clinical improvement suggested in the additional analyses may explain the reduced sick leave observed with escitalopram, given its superior short-term efficacy compared with duloxetine (demonstrated in the underlying clinical trial).
