Summary

Two years of prescriptions for all the drugs included in the Italian National Formulary by 3,866 general practitioners, in a region of Northern Italy of almost 4 million inhabitants, were analysed to determine the pattern of drug use.

The data (official code and proprietary name of the drug, number of packages prescribed, price of the drug, dispensing pharmacy, and date of dispensing) were collected monthly by retail pharmacies and were recorded and organized in database files.

Quantitative and qualitative profiles of prescription patterns were studied for all the major therapeutic areas. Overall drug prescriptions averaged 600 DDD/1,000 inhabitants/day. Comparison of 1988 and 1989 data showed only a slight increase in total drug prescriptions, but greater changes were detected in certain drug groups, expecially those recently marketed. Overprescription of well-documented drugs, such as H2-antagonists, ACE-inhibitors, calcium antagonists and the HMG-CoA-reductase inhibitors, in comparison to other countries was shown. There was frequent prescribing of drugs devoid of documentation of their clinical efficacy, which were mainly given for clinical conditions lacking a specific treatment, or as placebos for minor disorders.

The data demonstrate the need for educational intervention to improve the quality of drug prescribing habits in primary health care in Italy.
