Exploring pharmacological interventions in benign prostate hyperplasia: the role of cost-effectiveness analysis in daily practice and future directions

INTRODUCTION

Benign Prostate Hyperplasia (BPH) significantly impacts men's health and quality of life, with its prevalence rising with age. This review critically examines the cost-effectiveness of pharmacological interventions for BPH to optimize patient outcomes and healthcare resource utilization.

AREAS COVERED

This review explores the integration of cost-effectiveness analysis (CEA) into clinical practice, balancing clinical efficacy with economic efficiency in BPH management. We performed a critical literature search, including recent studies on the economic evaluation of BPH treatments, focusing on pharmacotherapies such as alpha-blockers and 5-alpha reductase inhibitors. Additionally, we discussed the concept of CEA and evaluated the role of medicinal reconciliation and the avoidance of polypharmacy in favor of optimal BPH treatment.

EXPERT OPINION

Cost-effectiveness analysis is crucial for evaluating BPH treatments, with evidence suggesting a shift towards surgical interventions may offer greater long-term economic benefits. However, these models must be applied cautiously, considering clinical evidence and patient preferences to ensure equitable and patient-centric healthcare.

Impact of baseline blood pressure on the magnitude of blood pressure lowering by nifedipine gastrointestinal therapeutic system: refreshing the Wilder's principle

Background

The objective of the study was to investigate the relationship between baseline blood pressure (BP) and the magnitude of BP reduction in patients with essential hypertension treated with nifedipine gastrointestinal therapeutic system (NGTS).

Methods and patients

One hundred and thirty-eight patients with essential hypertension were enrolled in this prospective, single-arm, open-label study. NGTS was administered for 24 weeks to achieve target BP of 140/90 mmHg. The dose could be uptitrated to 60 mg/d in case of unsatisfactory BP reduction after 4-week treatment. Home blood pressure measurement was recorded through the initial 1–14 days, and office BP and heart rate were evaluated at 2, 4, 8, 12, and 24 weeks.

Results

One hundred and seventeen patients (84.8%) completed the study, and their average BP decreased by 19.0/11.3 mmHg after 24 weeks. The reduction of either systolic or diastolic BP was positively correlated with baseline BP at weeks 2, 4, or 24 after treatment (r=0.603–0.762, all p<0.05). The maximal BP reduction was observed in 83% of patients at 4 weeks of treatment even though the dose of nifedipine remained unchanged (30 mg/day).

Conclusion

These findings show that BP reduction is greatly influenced by the baseline level. Patients with high baseline BP had maximum reduction after treatment with NGTS, and the maximal antihypertensive efficacy of NGTS could appear even at 4 weeks after treatment initiation.

Anti-hypertensive drugs have different effects on ventricular hypertrophy regression

OBJECTIVES

There is a direct relationship between the regression of left ventricular hypertrophy (LVH) and a decreased risk of mortality. This investigation aimed to describe the effects of anti-hypertensive drugs on cardiac hypertrophy through a meta-analysis of the literature.

METHODS

The Medline (via PubMed), Lilacs and Scielo databases were searched using the subject keywords cardiac hypertrophy, antihypertensive and mortality. We aimed to analyze the effect of anti-hypertensive drugs on ventricle hypertrophy.

RESULTS

The main drugs we described were enalapril, verapamil, nifedipine, indapamina, losartan, angiotensin-converting enzyme inhibitors and atenolol. These drugs are usually used in follow up programs, however, the studies we investigated used different protocols. Enalapril (angiotensin-converting enzyme inhibitor) and verapamil (Ca(++) channel blocker) caused hypertrophy to regress in LVH rats. The effects of enalapril and nifedipine (Ca(++) channel blocker) were similar. Indapamina (diuretic) had a stronger effect than enalapril, and losartan (angiotensin II receptor type 1 (AT1) receptor antagonist) produced better results than atenolol (selective beta1 receptor antagonist) with respect to LVH regression.

CONCLUSION

The anti-hypertensive drugs induced various degrees of hypertrophic regression.

Differences in lower urinary tract symptoms, treatment and mortality among African-American and white elderly men

BACKGROUND

There are limited population-based studies of benign prostate hyperplasia (BPH) and lower urinary tract symptoms (LUTS) in men, and most studies examined to date have been restricted to predominately white populations. This study examines treatment and all-cause mortality among a cohort of African-American and white men aged > or =65 with BPH/LUTS symptoms over time.

METHODS

Data were collected from the Piedmont Health Survey of the Elderly-Established Populations for the Epidemiological Study of the Elderly for 5 North Carolina counties from 1994 (N=502) to 1998 (N=322).

RESULTS

From 1994-1998, there were no significant racial differences in treatment by catheter insertion, prostate surgery or drug therapy for BPH/LUTS. However, overall use of the 3 treatments increased from 1994-1998, with drug therapy showing the largest increase. Adjusted analyses revealed racial differences in prostate surgery only, with African-American men nearly 40% more likely to receive prostate surgery than white men. Men with comorbid conditions were less likely to receive drug therapy, whereas those with poor self-reported health or cancer were more likely to receive prostate surgery. Catheter insertion was more likely for those who had resided in a nursing home. Men who received drug therapy treatment or had regular rectal exams showed decreased risk of mortality.

CONCLUSION

Findings suggest that healthcare providers should direct more attention to the management of LUTS in white and African-American elderly men. Data also demon-strate the need for studies that focus on treatment modalities as well as important correlates of LUTS.
