title: [Unused drugs returned to pharmacies. II].
abstract: The problems related to unused drugs kept in households and returned to pharmacies have been investigated from various viewpoints. After an analysis of preparations which had both the primary and secondary container, or only the primary one (set I), sets II (free blisters and strips), III (free solid dosage forms which occurred singly) IV (extemporaneously prepared medicinal preparations), and V (health service appliances) were analyzed. Out of set II (1,233 blisters), 274 (22.2%) were used and 959 (77.8%) were still complete, unused. The expiration period was over in 66.1% of blisters, 29.8% was still usable, and in 4.1% of blisters the expiration period could not be determined. The value of returned drugs was 185,287 Czech crowns, after conversion it was 61,762 Czech crowns.
