Main Point #1
Serious global inequities in access to
pharmaceutical products exist between rich and poor countries.
The Global Drug Gap
![Page 3: The Global Drug Gap: Access Inequities and Policy Implications](https://reader030.fdocuments.us/reader030/viewer/2022032607/56813061550346895d96301f/html5/thumbnails/3.jpg)
ICPE-Barcelona
Main Point #2
Strategies are needed for three categories:
•ESSENTIAL DRUGS •NEW DRUGS•YET-TO-BE-DEVELOPED
DRUGS

ICPE-Barcelona
Main Point #3
Policies need to include: •PUSH approaches (subsidies)•PULL approaches (incentives)•PROCESS approaches
(organizational strengthening)

Access to pharmaceuticals
• Access is not just a technical issue
• Access is connected to: – social values– economic interests– political processes
• Access is on the international agenda
![Page 7: The Global Drug Gap: Access Inequities and Policy Implications](https://reader030.fdocuments.us/reader030/viewer/2022032607/56813061550346895d96301f/html5/thumbnails/7.jpg)
ICPE-Barcelona
Too often, ‘access’ means
• Finding empty shelves in government health facilities
• Purchasing drugs from private drug stores
• Obtaining poor-quality drugs• Receiving little information
about dispensed products
![Page 8: The Global Drug Gap: Access Inequities and Policy Implications](https://reader030.fdocuments.us/reader030/viewer/2022032607/56813061550346895d96301f/html5/thumbnails/8.jpg)
ICPE-Barcelona
‘Access’ can also mean
Too many drugs:• Case of young girl in Bangladesh
with bloody dysentary• Prescribed 16 different
medications, mostly inappropriate
• Family sold some land in order to purchase the medicines
![Page 9: The Global Drug Gap: Access Inequities and Policy Implications](https://reader030.fdocuments.us/reader030/viewer/2022032607/56813061550346895d96301f/html5/thumbnails/9.jpg)
ICPE-Barcelona
Factors that affect access• Is the product available in the
national market?• Is the product distributed
within the country?• How does the prescription
process function?• How does payment work?

ESSENTIAL DRUGS
According to the World Health Organization, one-third of the world’s population does not have access to essential drugs and vaccines.

Essential drugs are:
“those that satisfy the health care needs of the majority of the population … [and that] should therefore be available at all times in adequate amounts and in appropriate dosage forms.”

WHO Model List of EDs:• 302 drugs in 27 therapeutic
categories in 1999 list• 90% of the products are off-
patent• adopted by nearly 150
countries • embodies principles of both
efficiency and equity

Strategy #1: INTERNATIONAL MARKET
• Strengthen state’s capacity to use the international market, for efficient procurement
• Related example: UNICEF’s global procurement service
Strategies for essential drugs

and distribution• Example: better control of
corruption
Strategies for essential drugs

ICPE-Barcelona
Strategy #3: MAINTAIN SUPPLIES• Focus on financial mechanisms
to maintain supplies• Example: community-managed
funds for drug purchasing• Example: international loans to
support procurement
Strategies for essential drugs

Strategies for essential drugs
Strategy #4: RATIONAL USE• Improve rational use of
essential drugs• Example: public detailing
directed at health workers• Example: social marketing
directed at consumers

Gap between rich and poor
“With each passing date, the gap between rich and poor countries in caring for people with HIV is becoming morally more reprehensible.”– Peter Piot, Executive Director,
UNAIDS, Sept 1999, Lusaka

An ethical dimension
Need to consider the fairness of the international distribution of research benefits

Not just HIV/AIDS drugs
Other examples:•Praziquantel for schistosomiasis
•Asthma treatments•Tuberculosis treatments

Strategies for new drugsStrategy #1: MARKET• Use the Market• Example: Purchase new drugs,
as Brazilian government has done for antiretrovirals, spending $230 M in 1998
• Related example: Develop market for patents
![Page 25: The Global Drug Gap: Access Inequities and Policy Implications](https://reader030.fdocuments.us/reader030/viewer/2022032607/56813061550346895d96301f/html5/thumbnails/25.jpg)
ICPE-Barcelona
Strategies for new drugsStrategy #2: MANDATES• Legal mandates for access• Example: Use compulsory
licensing by non-patent holders• But: Limited number of
countries with manufacturing capability; and political controversy
![Page 26: The Global Drug Gap: Access Inequities and Policy Implications](https://reader030.fdocuments.us/reader030/viewer/2022032607/56813061550346895d96301f/html5/thumbnails/26.jpg)

Strategies for new drugsStrategy #3: MUNIFICENCE• Expand donation programs
from pharmaceutical manufacturers
• Example: Merck’s donation program of ivermectin

Strategies for new drugsPublic and private actors must
resolve conflicting interests and establish partnerships and principles for access to new drugs.
Important implications for R&D system for generating new products.

Strategies for yet-to-be-developed drugs
Strategy #1: PUBLIC SUBSIDIES R&D
• Public subsidies for R&D on new products
• Example: NIH• Example: TDR for tropical
diseases
![Page 31: The Global Drug Gap: Access Inequities and Policy Implications](https://reader030.fdocuments.us/reader030/viewer/2022032607/56813061550346895d96301f/html5/thumbnails/31.jpg)
ICPE-Barcelona
Strategy #2: PARTNERSHIPS• Construct new public-private
partnerships on specific diseases or for specific products
• Example: Medicines for Malaria Venture

ICPE-Barcelona
Strategy #3: PRODUCT PATENTS• Protect product patents in
developing countries, to create incentives
• Example: TRIPS Agreement (Trade Related Aspects of Intellectual Property Rights)
Strategies for yet-to-be-developed drugs
![Page 33: The Global Drug Gap: Access Inequities and Policy Implications](https://reader030.fdocuments.us/reader030/viewer/2022032607/56813061550346895d96301f/html5/thumbnails/33.jpg)

Strategy #4: FINANCIAL INCENTIVES
• Create purchase funds or guaranteed markets, for private corporate research
• Example: Proposal for vaccine development

ICPE-Barcelona
Conclusion #1:
Issues of access to pharmaceuticals need to be addressed through multiple policies.
![Page 35: The Global Drug Gap: Access Inequities and Policy Implications](https://reader030.fdocuments.us/reader030/viewer/2022032607/56813061550346895d96301f/html5/thumbnails/35.jpg)
ICPE-Barcelona
Conclusion #2:
Solutions are needed that both protect incentives for R&D and reduce inequities of access.

Conclusion #3:
Strategies for Access Involve:
•Technical dimensions•Ethical dimensions•Political dimensions
