Abstract

Pharmacies have as one of the primary functions the promotion of safe and correct use of medicines, and to increase the safety of patients is necessary to avoid the prescription and dispensing errors. Based upon this context, the present study aimed to analyze medical prescriptions for inpatients of the Hospital Regional Deputy Janduhy Carneiro, in the city of Patos-PB. The study was cross-sectional, retrospective, with descriptive approach. The sample consisted of medical prescriptions of inpatients during the period from September 15 to October 10, 2014, sent to the Central Pharmacy of HRP. Among 500 prescriptions analyzed, 20% were entered and 80% written; of these, 90.75% were considered readable. A number of 2,583 drugs were prescribed, of which 24 (9.1%) were not standardized, 710 (27.5%) did not use the Brazilian Common Denomination, 318 (12.3%) were potentially dangerous drugs (MPP), 283 (10 , 9%) were considered Potentially Inappropriate Medications (MPI) by the Beers' criterion, and 60 (2.3%) MPI by the criterion of Priscus. The most prescribed therapeutic class was that of antibacterial for systemic use (22.4%). The most prescribed drug was Dipyrone 500mg (14.5%), however, among those who had ATC code, the most prescribed was the Tenoxicam 20mg (6.4%). Regarding information prescribers, were missing data as stamp (21.6%), signature (20.2%), date (13.4%) and dosage (3.2%); abbreviations were used in 18% of prescriptions. As for potential drug interactions (IM), 44.2% (178/403) were classified IM moderate severity, 43.9% (177/403) as higher and 11.9% (48/403) as lower; in major IM the most frequently found was Clopidogrel - Omeprazole (9.0%), and in moderate IM was Clopidogrel - simvastatin (9.5%). We conclude that the HRP requirements should be improved in many ways, to increase the level of patient safety.
