SESSION CONTENTS

STEP 1: Presentation of Session Title and Learning Tasks (5 minutes)

READ or ASK students to read the learning objectives and clarify

ASK students if they have any questions before continuing.

STEP 2: Substandard and CounterfeitMedicines (20 minutes)

Activity: Buzzing (5 minutes)

ASK students to pair up and buzz on the following question for 2 minutes

• What are the Substandard and Counterfeit Medicines?

ALLOW few pairs to respond and let other pairs to add on points not mentioned

WRITE their response on the flip chart/board

CLARIFY and SUMMARIZE by using the content below

• Counterfeit medicines are medicines that are deliberately and fraudulently mislabeled with

respect to identity and /or source.(WHO)

o Their quality is unpredictable as they may count the wrong amount of active ingredients.

o In all cases counterfeit medicines are manufactured secretly with no possibility of

control.

o Counterfeiting occurs both with branded and generic products.

o It has been found that counterfeiters copy or imitate existing products but they also

manufacture products that are completely invented

o Counterfeit medicines represent an enormous public health challenge.

o Anyone, anywhere in the world, can come across medicines seemingly packaged in the

right way but which do not contain the correct ingredients and, in the worst – case-

scenario may be filled with highly toxic substances.

o In some countries, this is rare occurrence, but in others, it is an everyday reality.

• Substandard medicine Any branded or generic drug that does not meet national or

international standards for quality, purity, strength, or packaging. ―And the amount of active

substance is lower or higher than as stated in standards for quality.

• Substandard products could result from

o Poor manufacturing practices,In some countries 10–20% of medicines fail laboratory

tests for quality, substandard products could result from poor manufacturing practices,

unsuitable packaging, storage and distribution or when generic drugs are produced by

unregistered manufacturers. Not only potency but also dissolution rates of tablets and

capsules are a problem ,Unsuitable packaging, Storage and distribution

o When generic drugs are produced by unregistered manufacturers.

o Forms in which substandard and counterfeit occurs

 Correct drug, correct ingredients not registered brand i.e. copies of original products

 Wrong ingredients, but therapeutically active

 No active ingredients

 Toxic ingredients

 Correct drug and quantities but fake packaging

 Products with high level of impurities and contaminants

 Incorrect quantities of Active Pharmaceutical Ingredient

STEP 3: Differences between Substandard and Counterfeit Medicines

(30mins)

Activity: Brainstorming (5 minutes)

Ask students to brainstorm on the following question:

• What is the difference between substandard and counterfeit medicine?

ALLOW few students to respond?

WRITE their responses on the flip chart/ board

CLARIFY and SUMMARISE by using the content below

• Both counterfeit drugs and substandard drugs can be harmful, but it is important

to understand that they are different.

• By contrast, counterfeit medicines, defined by the World Health Organization (WHO) as

―spurious/falsely-labelled/falsified/counterfeit‖ medicines, are ―deliberately and

fraudulently mislabelled with respect to identity and/or source‖ (World Health Organization

2010).

• Although substandard and counterfeit medicines are similar in that both have serious public

health implications, counterfeits are not produced by licensed manufacturers.

• Although counterfeits tend to be substandard (in that they do not contain correct amounts of

active ingredient), this is not inherent in the definition of counterfeits.

• The difference in manufacturers means the problems with substandard and counterfeit

medicines are distinct.

PST 06211 Monitoring and Evaluation of Medicines Use NTA Level 6 Semester 2 Facilitator Guide

114

• Substandard medicines, for example, can be controlled through effective regulation and

enforcement, because manufacturers are known and licensed. Counterfeits, however, can be

produced in homes, small industries, and backyards, and are harder to regulate (International

Medical Products Anti-Counterfeiting Taskforce 2008).

• Substandard medicines are made by licensed manufacturers operating within the framework

of national pharmaceutical regulatory standards.

• Also referred to as ―out of specification‖ products, these include medicines sold past their

expiration date, medicines that have been compromised in shipping or storage, and

medicines that are missing active ingredients or contain the wrong ratio of active ingredients

(World Health Organization n.d.c).

• Substandard medicines may arise due to human error, negligence, or resource restrictions

(World Health Organization 2003). They may result from both inadvertent and deliberate

actions by a legitimate manufacturer.

The differences exist between counterfeit and substandard medicine aresummarized in the table

below;

SUBSTANDARD MEDICINES COUNTERFEIT MEDICINES

When substandard medicines are found, the With counterfeit drugs, the company that

company that made them is known. manufactured them is unknown.

Consequently, the authorities can work with the Authorities cannot remove the problem

STEP 4: Effect of Substandard and Counterfeit Medicines to the Public

Health (35 minutes)

Activity: Small Group Discussion ( 20 minutes)

DIVIDE students into small manageable groups

ASK students to discuss on the following question

• What are effects substandard and counterfeit medicines to the public health?

ALLOW students to discuss for 15 minutes

ALLOW few groups to present and the rest to add points not mentioned

CLARIFY and SUMMARIZE by using the contents below

• Impacts of counterfeit drugs may be categorized into three categories namely;

o In public health

o In the health care system

o In industrial system

• The effect of substandard and counterfeit drugs in public health include the following;

o Therapeutic failure;the regular use of substandard or counterfeit medicines can lead to

therapeutic failure or drug resistance; in some cases it can lead to death.For example:

During a meningitis epidemic in Niger in 1995, more than 50 000 people were

inoculated with fake vaccines, received as a gift from a country which thought they were

safe. The error resulted in 2500 deaths.

o Increase of mortality and morbidity;It is difficult to quantify the continental

morbidity and mortality toll of counterfeit or falsified medical products. There have

been no comprehensive studies to quantify its damage. Estimates put the total loss of life

to counterfeit pharmaceuticals between 500000 and 1 million people each year

(Kafchinski, 2009).

o In 1999, at least 30 people died in Cambodia after taking counterfeit antimalarials

prepared with sulphadoxine-pyrimethamine (an older, less effective ant malarial) which

were sold as Artusenate.

o Drug resistance (especially against antibiotics);Perhaps one of the most worrying

implications of the global boom in counterfeit medicines is the acceleration of new,

drug-resistant strains of viruses, parasites and bacteria. Counterfeit medicines for

infectious diseases containing too little or sub-therapeutic amounts of active ingredients

destroy the clinical efficacy of the genuine medicine by promoting drug resistant

pathogens.

PST 06211 Monitoring and Evaluation of Medicines Use NTA Level 6 Semester 2 Facilitator Guide

117

o Undermining public confidence in medicines;Patients who take counterfeits fail to get

better and lose faith in the effectiveness of modern medicine. In Asia where

complementary medicine is widespread, patients may turn instead to traditional or herbal

medicine. Counterfeit or falsified medicines may create the wrong impression that the

medicines themselves are ineffective and, thus, lead prescribers to unnecessarily opt for

others as their first line treatment

o Betraying the vulnerability of the pharmaceutical supply system;This is due to

interference of substandard and counterfeit in the supply chain

o Compromise credibility of national authorities;It causes devaluation of drug

authorities such TFDA

o Impact of cost;Counterfeit or falsified medicines may create the wrong impression that

the medicines themselves are ineffective and, thus, lead prescribers to unnecessarily opt

for others as their first line treatment which are of higher costs.

• Effects in health care system

o Loss of facility‘s public trust

o Growth of Irrational prescribing

o Nosocomial infections exist, since drugs are not treating diseases.

o Ethical deviation to health practitioners

o Hospital underserviced concept arise Jeopardizing credibility of national authorities

• Effects in drug industrial system

o Take away incremental revenue from the pharmaceutical companies – the vast majority

of which would have gone straight to their bottom lines.

o Some country‘s regulations, insist companies responsibilities to counterfeit medicines,

including withdrawing product from the supply chain. This could result in loss of lot of

money to the respective company.

o Drug industry profile gone down, this could lead negative market environment

STEP 5: Challenges in Prevention of Counterfeit and Substandard Medicines

(10 minutes)

• Lack of regulation and enforcement; the quality, safety and efficacy of both imported and

locally manufactured medicine in many developing countries cannot be guaranteed but lack

of regulation and enforcement poses challenge

• Unawareness of the consumer; most consumer cannot differentiate between counterfeit or

substandard and standard medicines

• Use of Inadequate equipments with low quality; the availability of the equipment is low so

is the quality e.g.; most parts of developing countries example Tanzania do not have this

equipments which makes it hard in preventing counterfeit/ sub-standards medicines

PST 06211 Monitoring and Evaluation of Medicines Use NTA Level 6 Semester 2 Facilitator Guide

118

• Lack of motivation to specific authority boards like FDAs lack motivation in fighting to

prevent counterfeit and sub-standards medicines

STEP 6: Key Points (10 minutes)

• Counterfeit medicines are medicines that are deliberately and fraudulently mislabeled with

respect to identity and /or source.(WHO)

• Substandard medicine any branded or generic drug manufactured by a registered company

that does not meet national or international standards for quality, purity, strength, or

packaging. ―And the amount of active substance is lower than as stated in standards for

quality.

• When substandard medicines are found the company that made them is known while for

counterfeit manufacturer is unknown

• Effect of substandard and counterfeit medicines to the public health includes therapeutic

failure,drug resistance, costs and compromise of drug authorities.

STEP 7: Evaluation (5 minutes)
