AIM: To evaluate the prescription rate of respiratory drugs (ATC code R03) in an Italian community setting and to estimate the extent of off-label use by both age and indication. METHODS: A cohort study aimed at evaluating prescriptions of drugs with ATC code R03 was conducted for the period 2002-2006. Data source was the PEDIANET Database. RESULTS: Ninety percent of R03 prescriptions are covered by 11 active substances or combinations, corresponding to 67 medicinal products. Inhaled corticosteroids are the most prescribed anti-asthmatic agents, followed by short-acting beta2 mimetics. The mean off-label rate is 19 and 56%, by age and indication respectively. The majority of off-label uses is among children under the age of 2. Five active substances are used at dosages not supported by adequate dose-finding studies. CONCLUSION: In Italy, many respiratory drugs are approved for the treatment of paediatric respiratory diseases, but a remarkable percentage of their prescriptions is off-label. This pharmaco-utilization study demonstrates that there is a need to perform clinical studies aimed at increasing the current knowledge on marketed paediatric drugs, and to revise and re-label the existing regulatory documents to reduce their off-label uses.

Abstract

AIM: To evaluate the prescription rate of respiratory drugs (ATC code R03) in an Italian community setting and to estimate the extent of off-label use by both age and indication. METHODS: A cohort study aimed at evaluating prescriptions of drugs with ATC code R03 was conducted for the period 2002-2006. Data source was the PEDIANET Database. RESULTS: Ninety percent of R03 prescriptions are covered by 11 active substances or combinations, corresponding to 67 medicinal products. Inhaled corticosteroids are the most prescribed anti-asthmatic agents, followed by short-acting beta2 mimetics. The mean off-label rate is 19 and 56%, by age and indication respectively. The majority of off-label uses is among children under the age of 2. Five active substances are used at dosages not supported by adequate dose-finding studies. CONCLUSION: In Italy, many respiratory drugs are approved for the treatment of paediatric respiratory diseases, but a remarkable percentage of their prescriptions is off-label. This pharmaco-utilization study demonstrates that there is a need to perform clinical studies aimed at increasing the current knowledge on marketed paediatric drugs, and to revise and re-label the existing regulatory documents to reduce their off-label uses.
