Cost-effectiveness of two transdermal nitroglycerin controlled-release systems.

J W Hay, W L Hill

Clinical Therapeutics

|January 1, 1985

Summary

Transdermal nitroglycerin patches TDN and ND were compared for cost-effectiveness. TDN patches demonstrated superior adhesion, leading to significant cost savings in prescription costs over a four-week period.

Background:

Transdermal drug delivery systems offer a convenient route for administering medications like nitroglycerin.
Comparing the cost-effectiveness and performance of different transdermal systems is crucial for optimizing patient care and resource allocation.
Adhesion properties of transdermal patches can significantly impact drug delivery efficacy and overall treatment costs.

Purpose of the Study:

To evaluate the cost-effectiveness of two transdermal nitroglycerin systems, TDN and ND.
To assess the impact of adhesive properties on the performance and cost of these systems.

Main Methods:

A comparative analysis of two transdermal nitroglycerin systems (TDN and ND) was conducted.
Cost-effectiveness was determined by analyzing wholesale prescription costs over a four-week period.
Multivariate regression analyses controlled for patient demographics (age, sex, BMI) and study location.

Main Results:

The TDN system exhibited superior adhesion compared to the ND system.
TDN resulted in an estimated 14.5% savings in wholesale prescription costs ($22.93 vs $26.82) over four weeks.
Adhesive superiority of TDN was independent of patient variables and study location, indicating intrinsic patch performance.

Conclusions:

TDN transdermal nitroglycerin patches offer a more cost-effective option due to their superior adhesion.
The intrinsic adhesive properties of TDN contribute to significant cost savings in prescription drug spending.
Healthcare providers should consider the adhesive performance of transdermal systems when makingPrescribing decisions for nitroglycerin therapy.
