Exposure-based sampling reveals low risk of substandard cardiovascular and diabetes medicines in Malang District
A targeted sampling methodology, reflecting actual patient exposure, found that cardiovascular and diabetes medications in Malang District, Indonesia, met quality standards, suggesting a lower risk of substandard drugs than previously indicated by broader, less targeted studies.
medRxiv · 2022
Key Findings
- 01All 204 tested samples of cardiovascular and diabetes medicines met specifications for both active ingredient assay and dissolution.
- 02None of the samples were suspected of being falsified.
- 03The exposure-based sampling method suggested a very low risk of substandard medicines to patients in Malang District.
Application
Design takeaway
When assessing product quality or market risks, prioritize sampling methods that directly correlate with actual consumer usage and accessibility to obtain more representative data.
How to apply
When designing a market entry strategy or a quality control program for a new product, consider how to sample and test products in a way that reflects how consumers will actually encounter and use them.
Project actions
- 01When planning your research, think about how your participants will actually interact with the product or system you are studying.
- 02Consider if your sampling method truly represents the real-world use of the item you are investigating.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Employed a novel and relevant sampling methodology (exposure-based).
- +Conducted rigorous laboratory testing for quality assurance.
Limitations
The findings are specific to Malang District and may not be generalizable to other regions or countries. The study focused only on assay and dissolution, not on other potential quality defects or the efficacy of the medications.
Reliability & validity
Reliability is supported by the use of standardized laboratory tests (HPLC, dissolution). Validity is enhanced by the exposure-based sampling method, which aims to improve the ecological validity of the findings by reflecting real-world drug use.
Think critically
How might the economic and regulatory landscape of Malang District have influenced the quality of medicines, and to what extent could these findings be generalized to other regions with different market structures?
Design Principles
"Market risk assessment should be informed by actual consumer exposure patterns."
This research highlights the critical importance of employing exposure-based sampling in market research and quality control. Traditional sampling methods may overestimate risks by not accounting for actual product usage and patient access, leading to potentially misdirected regulatory efforts and market perceptions.
What This Means for Your Design
This study shows that if you test medicines based on how many people actually use them, you can get a better idea of whether they are good quality. In one area of Indonesia, the medicines tested were all good, meaning people were likely not at high risk from bad drugs.
How to use in your project
- 1.Reference this study when discussing the importance of representative sampling in your design project's methodology section, particularly if your project involves assessing product quality or user behaviour in a specific market.

Paragraph starter
This research highlights the critical need for exposure-based sampling in quality assessment. By mirroring actual patient consumption patterns in Malang District, Indonesia, the study revealed that cardiovascular and diabetes medications met quality standards, contradicting broader concerns about substandard drugs in LMICs. This underscores the importance of tailoring sampling strategies to reflect real-world usage for accurate risk assessment and market understanding.
