Heterogeneity of the pharmacologic treatment of allergic rhinitis in Europe based on MIDAS and OTCims platforms.

BACKGROUND: The practice of allergology varies widely between countries, and the costs and sales for the treatment of rhinitis differ depending on practices and health systems. To understand these differences and their implications, the rhinitis market was studied in some of the EU countries. METHODS: We conducted a pharmaco-epidemiological database analysis to assess the medications that were being prescribed for allergic rhinitis in the years 2016, 2017 and 2018. We used the IQVIA platforms for prescribed medicines (MIDAS®- Meaningful Integration of Data, Analytics and Services) and for OTC medicines (OTC International Market Tracking-OTCims). We selected the five most important markets in the EU (France, Germany, Italy, Poland and Spain). RESULTS: Intranasal decongestants were excluded from the analyses because they are rarely prescribed for allergic rhinitis. For both Standard Units (SU) and costs, France is leading the other countries. In terms of SU, the four other countries are similar. For costs, Poland is lower than the three others. However, medication use differs largely. For 2018, in SU, intranasal corticosteroid is the first treatment in Poland (70.0%), France (51.3%), Spain (51.1%) and Germany (50.3%), whereas the Italian market is dominated by systemic antihistamines (41.4%) followed by intranasal corticosteroids (30.1%). Results of other years were similar. DISCUSSION: There are major differences between countries in terms of rhinoconjunctivitis medication usage.

Cost comparison of outpatient treatment with granulocyte colony-stimulating factors (G-CSF) in Germany.

BACKGROUND: Granulocyte colony-stimulating factors (G-CSF), are available for prevention of neutropenia and reduction of its complications in cytostatic chemotherapy. The purpose of this analysis was to determine the consumption rates for various G-CSF and to compare outpatient medication costs per patient and treatment cycle. METHODS: Prescription data of statutory health insurance members in Germany (IMS®LRx database) with G-CSF prescriptions between January 2008 and July 2010 were evaluated. A period of observation of at least 6 months prior to and after the G-CSF prescription was required. RESULTS: Prescription data of 8,726 patients treated with original filgrastim, 4,240 with biosimilar filgrastim, 6,456 with lenograstim, and 9,939 with pegfilgrastim were analyzed. The regression model showed statistically significant costreducing effects per cycle for treatment with lenograstim compared with non-lenograstim (-0.47 vs. original filgrastim; -0.15 vs. biosimilar filgrastim; -1.04 vs. pegfilgrastim; each p < 0.0001). This result has been adjusted for patient age, gender, number of injections, and prescribing specialist group. CONCLUSIONS: Treatment with the original preparation lenograstim is significantly cheaper compared to the other two original drugs and biosimilar. The costs of G-CSF treatment with the original preparation lenograstim and the filgrastim biosimilars are in a similar range, but with a significantly lower cost for lenograstim. Compared to their reference product the biosimilars thus show a cost advantage.

Antihypertensive treatment and risk of dementia: a retrospective database study.

OBJECTIVE: Vascular risk factors play an important role in the pathogenesis of vascular dementia, as well as in Alzheimer disease. The effect of antihypertensive medication on risk of dementia is unclear. The aim was to investigate the association between antihypertensive prescriptions and incident dementia, using a primary care database. METHODS: The analysis was based on 575 general and internal practices in Germany (10/2003 - 09/2008) (Disease analyzer database). Antihypertensive medication (ATC codes) during 3 years before newly diagnosed dementia (ICD codes or specific medication) in 1,297 patients was compared to 1,297 controls without dementia after matching for age (mean age: 80.6 ± 8.6 y), sex (females: 62%) and date of diagnosis. Conditional logistic regression was used to calculate crude and adjusted odds ratios (95% confidence intervals). RESULTS: Betablocker prescriptions (≥ 1 per year over 3 y) showed a significant inverse association with newly diagnosed dementia (Odds ratio, OR: 0.79 95% CI 0.61 - 0.99) after adjusting for demographic covariates, health care use, and cardiovascular and neurological comorbidity. In the fully adjusted model, ACE inhibitors also tended to be inversely associated with incident dementia, but failed statistical significance (OR 0.84 95% CI 0.65 - 1.08). Calcium channel blockers were positively related to cognitive impairment only in the crude analysis. The other drug groups were not significantly related to dementia (diuretics OR: 0.89; 0.67 - 1.19; angiotensin- 1-inhibitors OR: 1.04; 0.66 - 1.64). CONCLUSIONS: This practice-based case-control study indicated a possible protective effect of some antihypertensive agents (betablockers, ACE-inhibitors) on the development of dementia. Randomized controlled trials are required to confirm this finding.

A retrospective database analysis on persistence with inhaled corticosteroid therapy: comparison of two dry powder inhalers during asthma treatment in Germany.

BACKGROUND: Asthma is one of the most common chronic diseases worldwide. Patient persistence with treatment is essential to achieve sufficient outcomes, in particular to avoid exacerbations. OBJECTIVE: To investigate inhaled corticosteroid (ICS) therapy with two different inhalers (Novolizer® and Turbuhaler®) by comparing persistence, concomitant use of additional asthma medication and occurrence of exacerbations in real life. STUDY DESIGN: A retrospective analysis of prescription data from outpatient treatment was performed using the IMS Disease Analyzer. It provides longitudinal anonymized patient data from ~ 3,000 office-based physicians in Germany. Treatment persistence of asthma patients (ICD 10 code: J45) using 200 µg budesonide either via Novopulmon®/Budecort® (Novolizer group = NOV) or Pulmicort® (Turbuhaler group = TUR) was compared. Eligible patients hadthe first prescription of ICS medication (index day) between June 2001 and September 2007 and a data history available for at least twelve months before and after the index day. RESULTS: Analysis of 1,780 NOV and 664 TUR patients revealed that 1 year after index day, 89% NOV patients remained on their ICS compared to 85% TUR patients. NOV patients changed significantly less often and later to another ICS (p = 0.0108; log-rank test). Significantly fewer NOV patients switched temporarily or permanently to another ICS during the observation time (NOV group: 14.7%; TUR group: 20.8%; p = 0.0002, log-rank test). On average, NOV and TUR patients received comparable prescriptions of short acting medication (NOV more SABA, TUR more formoterol). There was a trend towards fewer prescriptions of systemic corticosteroids in NOV patients. CONCLUSIONS: Our results suggest better therapy persistence with NOV compared to TUR during asthma treatment in Germany. This can be a marker of better compliance and may contribute to prevent exacerbations. However, the number of exacerbations per patient year in the NOV group (0.12) compared to the TUR group (0.18) was not statically significantly lower (p = 0.4096).

Persistence with antihypertensive treatments: results of a 3-year follow-up cohort study.

OBJECTIVE: Effective treatment of hypertension requires continued prescribing of antihypertensive medications for many years. Persistence in prescribing habits, however, has been reported to be low. The study described herein - which is completely independent of pharmaceutical sponsors - was undertaken to evaluate persistence with antihypertensive treatment in Germany. METHODS: A total of 13,763 newly diagnosed hypertensive patients were identified in the IMS Disease Analyzer database and observed for 3 years after their first antihypertensive prescription. RESULTS: The median age of the study cohort was 65 years, and 56% were female. One in four patient received no more than three prescriptions within 3 years. Persistence was longest for patients whose initial prescription was for a free combination based on angiotensin converting enzyme inhibitors (median: 392.5 days), followed patients initially receiving a fixed combination, including angiotensin II receptor antagonists (208.5 days) and AIIRA monotherapy (168 days). Persistence was shortest with diuretics (57 days). Across all treatment groups, persistence after 3 years was 15.2%. Insurance status, sex and comorbidities were not found to impact persistence. CONCLUSION: Our data indicate that persistence differs markedly among the drug classes (p < or = 0.001) but that even persistence of the best drug class is not sufficient to provide for an adequate blood pressure control in the population. The largest decline in persistence occurred in the first 3 months of treatment. More research is needed to elucidate the causes of this early drop in persistence and to develop effective means of improving the currently unsatisfactory situation.
