Aims The aims were to analyze the dynamics of the medicines formulary in a middle-income country and to analyze the concordance of the included medicines with the national Clinical Practices Guidelines (CPG). Methods Medicines and their indications of use included in the Mexican Reference Drug List (Mex-RDL) from 1996 to 2013 were analyzed. The top 10 indications with the highest number of medicines in 2013 were analyzed retrospectively until 1996 in order to identify the increase in the number of medicines to treat each one, as well as the progressive specificity of the indication according to the International statistical Classification of Diseases (ICD-10). The concordance between the CPG and medicines approved for the top 10 indications was studied. Results The number of medicines included in the Mex-RDL kept constantly growing from 454 drugs in 1996 to 811 in 2013. Up to 26.3% of these medicines were approved to treat only 10 indications (1.5% of all possible indications of use). Many of these new medicines had been approved for more and more specific indications, while the oldest ones had been approved for general indications. Up to 27.6% of the medicines approved for these top 10 indications do not appear in the updated recommendations of the specific CPG for those indications. Conclusions During the last 18 years, the new medicines and indications included in the Mex-RDL were redundant and concentrated into few similar clinical conditions. This is a factor that promotes an irrational use of these medicines and, thus, unnecessarily raises the price of health care, undermines the quality of the health system and probably increases the uncertainty of treatments. © 2014 The British Pharmacological Society.

Pharmacoepidemiology and Drug Safety

Purpose: Gliptins are new oral antidiabetic drugs that increase insulin levels through dipeptidyl peptidase-4 inhibition. Recently, the association of serious musculoskeletal (MSk) adverse effects with the gliptin use has been suggested. The aim is to describe and analyze the characteristics of spontaneous reports related to these adverse effects and gliptin use. Methods: All spontaneous reports with MSk disorders associated with gliptins gathered in the Spanish pharmacovigilance database until May 2012 were described and analyzed using a case/non-case method. Results: Gliptins were reported as the suspected drug in 332 cases: 208 involved sitagliptin, 115 vildagliptin, and nine saxagliptin. In 34 patients (10.2% of total reports with gliptins), MSk reactions were described (22 women [64.7%] and 12 men [35.3%]). Their mean age was 65.1years; 41.2% were younger than 65years. Only seven cases were serious, but the gliptin had to be withdrawn in 22 patients because of intolerance and/or persistence of MSk discomfort, and patients recovered after its discontinuation. A positive re-challenge was observed in two cases. In seven cases, the patients were on previous chronic treatment with statins, and began to present MSk complaints shortly after starting a gliptin. The reporting odds ratio (ROR) for myalgia and arthralgia were strongly associated with gliptin use (ROR 1.96 [95% CI 1.12-3.43], p<0.05 and ROR 2.69 [95% CI 1.38-5.24], p<0.05, respectively). Conclusions: Musculoskeletal disorders are adverse reactions strongly associated with gliptins that, despite not being serious, may impair the treatment adherence in patients with type 2 diabetes. Future observational studies could confirm these findings. © 2013 John Wiley & Sons, Ltd. Source

Background: The aim of this study was to describe the patterns of cannabis use and the associated benefits reported by patients with fibromyalgia (FM) who were consumers of this drug. In addition, the quality of life of FM patients who consumed cannabis was compared with FM subjects who were not cannabis users. Methods: Information on medicinal cannabis use was recorded on a specific questionnaire as well as perceived benefits of cannabis on a range of symptoms using standard 100-mm visual analogue scales (VAS). Cannabis users and non-users completed the Fibromyalgia Impact Questionnaire (FIQ), the Pittsburgh Sleep Quality Index (PSQI) and the Short Form 36 Health Survey (SF-36). Results: Twenty-eight FM patients who were cannabis users and 28 non-users were included in the study. Demographics and clinical variables were similar in both groups. Cannabis users referred different duration of drug consumption; the route of administration was smoking (54%), oral (46%) and combined (43%). The amount and frequency of cannabis use were also different among patients. After 2 hours of cannabis use, VAS scores showed a statistically significant (p<0.001) reduction of pain and stiffness, enhancement of relaxation, and an increase in somnolence and feeling of well being. The mental health component summary score of the SF-36 was significantly higher (p<0.05) in cannabis users than in non-users. No significant differences were found in the other SF-36 domains, in the FIQ and the PSQI. Conclusions: The use of cannabis was associated with beneficial effects on some FM symptoms. Further studies on the usefulness of cannabinoids in FM patients as well as cannabinoid system involvement in the pathophysiology of this condition are warranted. © 2011 Fiz et al. Source

Expert Opinion on Drug Safety

Background: Renal impairment associated with dronedarone use is hardly known. Our aim is to describe the characteristics of spontaneous reports involving renal adverse reactions with use of dronedarone.Methods: In the Spanish Pharmacovigilance database, reports with renal reactions and dronedarone until May 2014 were retrieved and analyzed. Also, a review of case reports of renal failure and dronedarone was conducted in MEDLINE.Results: Dronedarone was found as a suspected drug in 192 reports, 10 (5.2%) of these reports described renal reactions. Renal reactions appeared until 3 months after the onset of dronedarone treatment. In 5 out of 10 cases, dronedarone was withdrawn and the patient recovered. The Reporting Odds Ratio was 2.88 [95% CI 1.52-5.46; p < 0.05]. Additionally, eight cases were found in the medical literature. In five of them, the patient outcome was described as recovered. One patient had to undergo hemodialysis for the treatment of their renal impairment.Conclusions: The effect of dronedarone on the renal function is supported by limited information; therefore, the cases from spontaneous reporting system and those from the medical literature could give relevant additional information. Our analysis shows a potential relationship between dronedarone use and renal impairment. Further studies are needed to confirm these findings. © 2015 Informa UK, Ltd. Source

Drug utilization (DU) studies in inpatient settings at a national level are rarely conducted. The main objective of this study was to review the general information on hospital medicine management in Europe and to report on the availability and characteristics of nationwide administrative drug consumption databases. A secondary objective was to perform a review of published studies on hospital DU of a group of selected drugs, focusing on methodological characteristics (ATC/DDD). General information on hospital drug management was retrieved from several websites, nationwide administrative drug consumption databases and reports published by governmental organizations. A PubMed search was conducted using keywords related to the selected group of drugs AND 'hospital drug utilization'. The data sources for hospital DU information varied widely and included 14 databases from 25 reviewed countries. Bulgaria, Croatia, Denmark, Estonia, Finland, France, Hungary, Iceland, Latvia, Norway and Sweden obtain information on inpatient DU at a national level from wholesalers/manufacturers. In Belgium, Italy and Portugal, drugs dispensed to patients in hospitals are registered at a national level. Data are freely available online only for Denmark and Iceland. From the PubMed search, of a total of 868 retrieved studies, only 13 studies used the ATC/DDD methodology. Although the number of DDD/100 bed-days was used in four studies, other units of measure were also used. The type of information provided for the inpatient sector allowed primarily for conducting DU research at an aggregated data level. The existence of national administrative structures to monitor hospital DU would contribute to promoting the rational use of medicines and improving the safety and quality of prescribing. © 2014 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).
