The various drugs that were studied showed different changes in clearance in relation to disease severity, and a 'one size fits all' solution does not exist without considering the multiple sources of the changes. Predictions of the effects of liver cirrhosis on drug clearance are of potential value in the design of clinical studies during drug development and, clinically, in the assessment of likely dosage adjustment.
PIP prevalence in European community-dwelling older adults is high and depends partially on the data collection method used. Polypharmacy, poor functional status, and depression were identified as the most common risk factors for PIP.
AIMSFew well-designed randomized controlled trials have been conducted regarding the impact of community pharmacist interventions on pharmacotherapeutic monitoring of patients with chronic obstructive pulmonary disease (COPD). We assessed the effectiveness of a pharmaceutical care programme for patients with COPD.
METHODSThe pharmaceutical care for patients with COPD (PHARMACOP) trial is a single-blind 3 month randomized controlled trial, conducted in 170 community pharmacies in Belgium, enrolling patients prescribed daily COPD medication, aged ≥50 years and with a smoking history of ≥10 pack-years. A computer-generated randomization sequence allocated patients to an intervention group (n = 371), receiving protocol-defined pharmacist care, or a control group (n = 363), receiving usual pharmacist care (1:1 ratio, stratified by centre). Interventions focusing on inhalation technique and adherence to maintenance therapy were carried out at start of the trial and at 1 month follow-up. Primary outcomes were inhalation technique and medication adherence. Secondary outcomes were exacerbation rate, dyspnoea, COPD-specific and generic health status and smoking behaviour.
RESULTSFrom December 2010 to April 2011, 734 patients were enrolled. Forty-two patients (5.7%) were lost to follow-up. At the end of the trial, inhalation score [mean estimated difference (Δ),13.5%; 95% confidence interval (CI), 10.8-16.1; P < 0.0001] and medication adherence (Δ, 8.51%; 95% CI,; P < 0.0001) were significantly higher in the intervention group compared with the control group. In the intervention group, a significantly lower hospitalization rate was observed (9 vs. 35; rate ratio, 0.28; 95% CI, 0.12-0.64; P = 0.003). No other significant between-group differences were observed.
CONCLUSIONSPragmatic pharmacist care programmes improve the pharmacotherapeutic regimen in patients with COPD and could reduce hospitalization rates.
Modifying the surfaces of LPXs with hydrophilic PEG chains prevents them from aggregating in vitreous. In this way, LPXs are obtained that can freely move in vitreous, an absolute criterion for reaching the retina after intravitreal injection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
