Summary

Determining the optimal dose for antihypertensive drugs involves balancing efficacy and adverse effects. Clinical decisions require considering patient response, drug tolerability, and cost-effectiveness for ideal treatment outcomes.

Introduction: the role of combination therapy in modern antihypertensive therapy.

Journal of cardiovascular pharmacology·2000

Area of Science:

  • Pharmacology
  • Clinical Medicine
  • Health Economics

Background:

  • Defining the optimal dose-response curve for antihypertensive agents is crucial for effective treatment.
  • Pharmacological dose identification is straightforward, but clinical application presents complexities.

Purpose of the Study:

  • To explore the multifactorial considerations in establishing the ideal clinical dose of antihypertensive medications.
  • To analyze the interplay between drug efficacy, adverse effects, and cost in dose regimen selection.

Main Methods:

  • Constructing dose-response curves for both antihypertensive efficacy and adverse effects.
  • Evaluating the therapeutic window and tolerability of specific agents like lacidipine.
  • Considering practical factors such as combination therapy and cost-effectiveness.

Main Results:

  • The optimal clinical dose balances efficacy and adverse effects, often indicated by a wide therapeutic window.
  • Drugs with good efficacy and tolerability, like lacidipine, offer a favorable dose range.
  • Increasing single-drug dosage may be less effective than adding another agent, especially when dose-response curves plateau.

Conclusions:

  • Optimal antihypertensive dosing is a complex decision influenced by efficacy, tolerability, and cost.
  • Combination therapy can be more effective and cost-efficient than maximizing single-drug doses.
  • Achieving a balance between therapeutic benefit and patient safety at a competitive price is the primary goal.
