Prescribing patterns of tramadol in adults in IMS® primary care databases in France and Germany between 1 January 2006 and 30 June 2016.

PURPOSE: There is increasing concern with regard to fatal intoxications with prescription opioids and tramadol poisonings. This study aimed to characterise prescribing patterns for tramadol in primary care in France and Germany and identify long-term treatment and potential risk factors for such treatment. METHODS: Adult patients-prescribed tramadol between January 2006 and June 2016 in GP practices in IMS® Disease Analyzer databases in France and Germany were identified. Six-monthly prevalence and mean doses and durations were calculated by gender, age group and type of tramadol product. The proportion of incident use that resulted in treatment ≥ 366 days was calculated. The odds for long-term treatment was analysed in relation to gender, age group, type of tramadol product, start dose, indication and a diagnosis of abuse or misuse. RESULTS: Overall prescribing of tramadol decreased in Germany and increased, then plateaued in France. Prescribing was higher in females. Predominantly prescribed products were tramadol in combination with paracetamol (COMB) in France and slow release formulations of tramadol (SR-TRAM) in Germany. SR-TRAM had the highest mean doses and durations, followed by immediate release formulations of tramadol (IR-TRAM) and COMB. Around 1.5% of incident tramadol use in France and 8.2% in Germany resulted in long-term treatment. Long-term treatment was associated with increasing age, SR-TRAM and a diagnosis of abuse or misuse. CONCLUSIONS: The risk of long-term treatment appeared to increase with increasing age. Potential risk factors for long-term treatment included initiating treatment with SR-TRAM and a diagnosis of abuse or misuse.

Medicines for older people: assessment and transparency at the European Medicines Agency regarding cardiovascular and antithrombotic medicinal products.

PURPOSE: To describe whether for the cardiovascular and antithrombotic medicines approved in the period 2006-2016 (a) the pivotal trial was designed with an upper ageexclusion criterion, (b) the age distribution of the participants in the registration trials reflected expected use, (c) post-authorisation studies were planned, and d) the age distribution of participants was clearly presented in the approval documents. METHODS: The data provided to EMA in support of centralized marketing authorisations of were analysed. RESULTS: Two out of 19 protocols excluded patients over 80 and 85 years old. In the heart failure, atrial fibrillation and antithrombotic drug registration trials, the proportion of patients aged 65-74 years was 33-50%, and 13-20% over 75 years. For antithrombotic drugs, it was 25-35% for the 65-74 age, and around 15% for the 75+ age. For statins and antihypertensives, it was 20-40% for the 65-74 age and 3-6% for 75+ age. Post-authorisation studies were planned in two cases. An improvement on the transparency of public data is apparent, although information is not always presented clearly and uniformly. CONCLUSIONS: There is more publicly available information since 2006, but data on older patients with frailty and multimorbidity are generally scant. To address this, CHMP Geriatric Expert Group has currently published a Reflection paper on physical frailty to support subgroup categorisation of older patients beyond age with the aim of ensuring that clinical trial populations are representative of the users of the medicine.
