Aims: Our study aimed to assess whether a single pill concept (SPC) is superior to a multi pill concept (MPC) in reducing cardiovascular (CV) events, all-cause death, and costs in CV patients.

Method And Results: Anonymized medical claims data covering 2012-2018, including patients with hypertension, dyslipidemia, and CV diseases who started a drug therapy either as SPC or identical MPC were analyzed after 1:1-Propensity Score Matching (PSM). Hospitalizations with predefined CV events, all-cause mortality, and costs were studied in 25,311 patients with SPC and 25,311 patients with MPC using incidence rate ratios (IRRs) and non-parametric tests for continuous variables.

Article Synopsis
  • Single-pill combinations for treating hypertension improve patient adherence to medication compared to taking multiple pills, which may lead to better health outcomes.
  • A study using data from over 57,000 hypertensive patients analyzed the effects of single pills versus multiple pills on medication persistence and health outcomes such as cardiovascular events and all-cause mortality.
  • The findings indicate that single-pill therapy significantly lowers all-cause mortality and cardiovascular events while enhancing medication persistence, supporting current health guidelines for hypertension treatment.

Purpose: Discrepancies exist between guideline recommendations and real-world practice of blood pressure (BP) measurements. The aim of this study was to assess, with a nationwide, questionnaire-based survey, the current practice of BP measurement and associated BP values in German medical practices.

Material And Methods: A nationwide survey in German medical practices was performed in the period from 10 May 2021 to 15 August 2021.

This study assessed whether a single pill combination (SPC) is associated with lower direct healthcare costs. Anonymized claims data of patients ≥18 years treated with drugs for cardiovascular (CV)-related diseases either as a single pill combination or multi-pill combination (follow-up to 1 year) were evaluated. After propensity score matching, 59,336 out of 1,369,840 patients were analyzed.

Aim: Current guidelines for the treatment of arterial hypertension (AH) or cardiovascular (CV) prevention recommend combination drug treatments with single pill combinations (SPC) to improve adherence to treatment. We aimed to assess whether the SPC concept is clinically superior to multi pill combination (MPC) with identical drugs.

Methods And Results: In an explorative study, we analyzed anonymized claims data sets of patients treated with CV drugs for hypertension and/or CV disorders who were insured by the German AOK PLUS statutory health fund covering 01/07/2012-30/06/2018.

For efficient cardiovascular risk protection antihypertensive treatment is often combined with cholesterol-lowering treatment, although solid data of interaction and side effects are missing. This is a prospective, single-center interaction study conducted in a fixed sequence design at steady state of candesartan, amlodipine, and atorvastatin. Five-day monotherapy of candesartan 8 mg was followed by 5-day atorvastatin 40 mg monotherapy and subsequently 9-day amlodipine 5 mg monotherapy; each treatment separated by washout phases.

Introduction: The principal objective of clinical guidelines is to improve the quality of medical care. However, standardized evaluation of the adoption into daily practice is missing. The aim of our study was to investigate the implementation of guideline recommendations on the management of arterial hypertension (AH) in German general practitioner's (GPs) offices.

Introduction: Cardiovascular diseases (CVD) represent the first cause of mortality in western countries. Hypertension and dyslipidemia are strong risk factors for CVD, and are prevalent either alone or in combination. Although effective substances for the treatment of both factors are available, there is space for optimization of treatment regimens due to poor patient's adherence to medication, which is usually a combination of several substances.

Objective: Knowledge of patients' treatment needs is an important requirement for comprehensive long-term patient care. The objective of this investigation was to assess the requirements of patients with Parkinson's disease (PD) regarding pharmacotherapy.

Methods: A total of 17,500 members of the German Parkinson Association were given the opportunity to anonymously answer a questionnaire about their health-related quality of life, PD pharmacotherapy and their improvement suggestions for new PD medication.

Objective: The objective of the study was to determine the maximal achievable dose of rotigotine by assessing the tolerability of escalating doses of rotigotine transdermal patch in patients with advanced-stage Parkinson disease.

Methods: Thirty-four patients aged 30 years or older on a stable dose of l-dopa with an off time of at least 2.5 h/d were randomized to 2-titration schemes.

Objective: Rotigotine (Neupro) is formulated as a transdermal delivery system designed to provide a selective, non-ergot D3/D2/D1 agonist to the systemic blood flow over a 24-hour period. In clinical trials, patches were applied once daily and uptitrated to the individual effective dose in increments of 2 mg/24 h every week. The aim of this analysis was to determine the safety of a more rapid titration of rotigotine by assessing the tolerability of escalating transdermal doses of rotigotine given in 2 different titration schemes.
