Medicine price and affordability in China and selected ASEAN countries: a cross-country comparison with forward-looking implications for regional pooled procurement
摘要
The China-ASEAN regional medical procurement platform was launched in early 2025. However, the scope and operational mechanisms of the platform remain unclear. This study aims to assess medicine prices and affordability in China and ASEAN countries, explore potential implementation challenges of the platform, provide policy suggestions.
MethodsWe selected commonly used medicines from four ATC categories (alimentary tract and metabolism, cardiovascular system, anti-infective for systemic use, nervous system). Prices were standardized to WHO defined-daily-dose (DDD) prices and converted into median price ratio (MPR) using Management Sciences for Health (MSH) international reference prices (IRP). All prices data were collected from official public sources and converted to US dollars using the official 2024 annual average exchange rate. Affordability was estimated the number of days’ statutory gross daily minimum wages required to purchase one DDD, with wage data obtained from the International Labor Organization (ILO). Descriptive statistics were performed.
ResultsA total of 68 medicines were included, with 68, 68, 60, and 59 available in China, Thailand, Indonesia, and the Philippines, respectively. Median MPRs were 0.88 (IQR:0.46–3.49), 0.97 (IQR:0.50–2.20), 1.69 (IQR:0.77–3.16), 1.86(IQR:0.72–5.03), respectively, and 45.6%, 45.6%, 61.7%, and 67.8% of medicines were priced above the IRPs. Prices varied widely across and within countries. For cardiovascular medicines, median MPRs exceeded the IRPs in China 1.72(IQR:0.53–6.30), Indonesia 1.79(IQR:0.78–2.80), the Philippines 2.85(IQR:1.31–6.43), while Thailand achieved a lower price of 0.78(IQR:0.31–1.37). The overall affordability was higher in China, Indonesia and Thailand, where one DDD of medicine required less than 6% of a day’s wage, with median values of 4.8% (IQR:2.5%-19.3%), 5.1% (IQR:2.3%-9.6%), and 3.6% (IQR:1.8%-8.1%), respectively, compared with 14.0% (IQR:5.4%-37.7%) in the Philippines. Sensitivity analysis excluding extreme affordability values yielded similar results.
ConclusionsOur findings suggest that understanding cross-country disparities in medicine prices and affordability may help inform the design of future regional purchasing strategies. Realizing the benefits of such joint procurement will require strong political commitment to establish a legal framework, enhance price transparency, harmonize regulations, and strengthen supply chains to ensure the platform’s effectiveness and sustainability.
