Clinical pharmacology facing the real-world setting: Pharmacovigilance, pharmacoepidemiology and the economic evaluation of drugs.

Traditionally, clinical pharmacology has focused its activities on drug-organism interaction, from an individual or collective perspective. Drug efficacy assessment by performing randomized clinical trials and analysis of drug use in clinical practice by carrying out drug utilization studies have also been other areas of interest. From now on, Clinical pharmacology should move from the analysis of the drug-individual interaction to the analysis of the drug-individual-society interaction. It should also analyze the clinical and economic consequences of the use of drugs in the conditions of normal clinical practice, beyond clinical trials. The current exponential technological development that facilitates the analysis of real-life data offers us a golden opportunity to move to all these other areas of interest. This review describes the role that clinical pharmacology has played at the beginning and during the evolution of pharmacovigilance, pharmacoepidemiology and economic drug evaluations in Spain. In addition, the challenges that clinical pharmacology is going to face in the following years in these three areas are going to be outlined too.

Risk of meningioma among users of high doses of cyproterone acetate as compared with the general population: evidence from a population-based cohort study.

AIM: Information from the spontaneous reporting system raised the hypothesis of an increased risk of meningioma in patients treated with high doses of cyproterone acetate (CPA). The objective of this study was to test the hypothesis of an increased risk of meningioma among users of high dose CPA as compared with non-users in a medical records computerized database. METHODS: A retrospective cohort study was performed in a Spanish primary care database (BIFAP). Meningioma incidence rates were compared in patients exposed to high dose CPA (users) with those non-exposed and with those exposed to low dose CPA. Poisson regression analysis was used to estimate the incidence rate ratios after adjusting for age and gender. RESULTS: Among 2474 users of high dose cyproterone (6663 person-years) four meningioma cases were identified, resulting in an incidence rate (IR) of 60.0 (95% CI 16.4, 153.7) per 100,000 person-years, which was significantly higher than that observed among the non-users (IR 6.6; 95% CI 6.0, 7.3) and among women users of low dose cyproterone (IR 0.0, 95% CI upper limit 5.5). After adjusting for age and gender, patients exposed to high dose CPA showed an increased risk of meningioma of 11.4 (95% CI 4.3, 30.8) as compared with non-users. CONCLUSIONS: The results of this study support the hypothesis that the exposure to high dose CPA increases the risk of meningioma.
