Analysis of Spanish generic medicines retail market: recommendations to enhance long-term sustainability

Policies and Practices Catalyzing the Use of Generic Medicines: A Systematic Search and Review

Background

The use of generic medicines instead of branded, is one of the main policies to decrease the expenditures and provide access to affordable and essential medicines in low and middle-income countries. The present study aims to systematically create a comprehensive synthesis of demand-side policies, encouraging the use of generic medicines.

Methods

The study systematically searched and reviewed the articles in Medline, Scopus, Web of Science, and Embase from 1.1.2000 to 12.5.2019. A total of 6435 records were identified during this period of time (Medline (n=315), Scopus (n=4323), Web of Science (n=71) and Embase (n=1726)). All stages are conducted according to the Preferred Reporting Item for Systematic Reviews and Meta-Analyzed (PRISMA).

Results

The encouraging policies and practices were classified into four categories from 44 articles analyzed, including; Prescribing, Dispensing, Patients/consumers, and healthcare organizations. Subthemes were also explored in relation to each category as; education, financial incentives, generic substitution, advertising approaches, and enforcement.

Conclusion

Various policies should be taken into consideration to encourage successful generic medication prescribing, dispensing, and consumption in both supply and demand-side. Economic, political, socio-cultural, technological, legal, and structural factors could as such accelerate the policies' effect. Studying the experience of successful countries can be helpful for policymakers.

Policies for biosimilar uptake in Europe: An overview

Background

Across European countries, differences exist in biosimilar policies, leading to variations in uptake of biosimilars and divergences in savings all over Europe.

Objectives

The aim of this article is to provide an overview of different initiatives and policies that may influence the uptake of biosimilars in different European countries. Recommendations will be formulated on how to create sustainable uptake.

Methods

An overview of policies on biosimilars was obtained via a questionnaire, supplemented with relevant articles. Topics were organized in five themes: availability, pricing, reimbursement, demand-side policies, and recommendations to enhance uptake.

Results

In all countries studied, biological medicines are available. Restrictions are mainly dependent on local organization of the healthcare system. Countries are willing to include biosimilars for reimbursement, but for commercial reasons they are not always marketed. In two thirds of countries, originator and biosimilar products may be subjected to internal reference pricing systems. Few countries have implemented specific incentives targeting physicians. Several countries are implementing pharmacist substitution; however, the scope and rules governing such substitution tend to vary between these countries. Reported educational policies tend to target primarily physicians, whereas fewer initiatives were reported for patients. Recommendations as proposed by the different country experts ranged from the need for information and communication on biosimilars to competitive pricing, more support for switching and guidance on substitution.

Conclusions

Most countries have put in place specific supply-side policies for promoting access to biosimilars. To supplement these measures, we propose that investments should be made to clearly communicate on biosimilars and educate stakeholders. Especially physicians need to be informed on the entry and use of biosimilars in order to create trust. When physicians are well-informed on the treatment options, further incentives should be offered to prescribe biosimilars. Gainsharing can be used as an incentive to prescribe, dispense or use biosimilars. This approach, in combination with binding quota, may support a sustainable biosimilar market.

Cost of treatment of peripheral neuropathic pain with pregabalin or gabapentin in routine clinical practice: impact of their loss of exclusivity

To analyze the effect of loss of exclusivity of data on the cost of treatment of peripheral neuropathic pain (PNP) with pregabalin or gabapentin in routine clinical practice. A retrospective observational study, with electronic medical records for patients enrolled at primary care centers managed by the health care provider Badalona Serveis Assistencials, who initiated treatment of PNP with pregabalin or gabapentin. The analysis used drugs and resources prices for year 2015. The 1163 electronic medical records (pregabalin; N = 764, gabapentin; N = 399) for patients (62.2% women) with a mean (standard deviation) age of 59.2 (14.7) years were analyzed. Treatment duration was slightly shorter with pregabalin than with gabapentin (5.2 vs 5.5 months; P = 0.124), with mean doses of 227.4 (178.6) mg and 900.0 (443.4) mg, respectively. The average study drug cost per patient was higher for pregabalin than for gabapentin; €214.6 (206.3) vs €157.4 (181.9), P < 0.001, although the cost of concomitant analgesic medication was lower; €176.5 (271.8) vs €306.7 (529.2), P < 0.001. The adjusted average total cost per patient was lower in those treated with pregabalin than in those treated with gabapentin; €2,413 (2119-2708) vs €3201 (2806-3.597); P = 0.002, owing to significantly lower health care costs; €1307 (1247-1367) vs €1538 (1458-1618), P < 0.001, and also non-health care costs; €1106 (819-1393) vs €1663 (1279-2048), P = 0.023, that was caused by a significantly lower use of concomitant medication, fewer medical visits to primary care, and fewer days of sick leave. After loss of exclusivity of both drugs, pregabalin continued to show lower health care and non-health care costs than gabapentin in the treatment of PNP in routine clinical practice.

Societal value of generic medicines beyond cost-saving through reduced prices

OBJECTIVE

This paper aims to provide an overview of the added societal value of generic medicines beyond their cost-saving potential through reduced prices. In addition, an observational case study will document the impact of generic entry on access to pharmacotherapy in The Netherlands and an illustrative exercise was carried out to highlight the budget impact of generic entry.

METHODS

A narrative literature review was carried out to explore the impact of generic medicines on access to pharmacotherapy, innovation and medication adherence. Data from the Medicines and Medical Devices Information Project database in The Netherlands were used for the case study in which the impact of generic medicine entrance on the budget and the number of users was calculated as an illustrative exercise.

RESULTS

Generic medicines have an additional societal value beyond their cost-saving potential through reduced prices. Generic medicines increase access to pharmacotherapy, provide a stimulus for innovation by both originator companies and generic companies and, under the right circumstances, have a positive impact on medication adherence.

CONCLUSION

Generic medicines offer more to society than just their cost-saving potential through reduced prices. As such, governments must not focus only on the prices of generic medicines as this will threaten their long-term sustainability. Governments must therefore act appropriately and implement a coherent set of policies to increase the use of generic medicines.
