[Unused drugs returned to pharmacies. I]
Abstract:
Drugs that have not been administered and have been stockpiled in households represent a medical, professional, and ecological problem. The present paper analyses and evaluates these drugs from qualitative, quantitative, and financial aspects. The material under study consisted of drugs returned to one pharmacy within a period of 1.5 months (April-May) in the year 1999. Out of set I (1,091 packages), 721 packages (66.1%) were used and 370 (33.9%) packages were original, i.e. unused. The expiration period was over in 78.3%, 16.8% could still be used, and in 4.9% it was impossible to determine their expiration period. The value of the returned drugs was 76,000 Czech crowns.
