摘      要：Background: The disposal of unused and expired medications has been a concern in many countries in that, the pharmaceutical waste enters the ecosystem and eventually causes a negative impact on human health and environment. Aim: To assess the knowledge, attitude and disposal practices of unused and expired medicines by students in the private medical universities in Lusaka of Zambia. Method: A cross-sectional survey was conducted over a period of 8 weeks among 391 respondents from three private universities in Lusaka. Respondents were polled using semi structured questions that focused on their knowledge, attitudes, and disposal practices for unused and expired drugs. In order to analyze data, the statistical package for social sciences (SPSS) version 20 was utilized. Results: The mean age of the participants was 23 years (SD: ±3).

The most commonly used disposal practice for unused 126 (32.2%) and expired medicines 274 (70.1%) was throwing them in household garbage.

Conclusions: The majority of the study participants used unsafe methods to dispose of unused and expired medicine. However, most of the participants acknowledged that un
