Effects of cardiovascular disease on pharmacokinetics
1Department of Pharmacology, University of Padova, Italy.
Insights
Cardiovascular disease alters drug kinetics, impacting how medications work. Understanding these changes is crucial for adjusting drug dosages and ensuring effective treatment.
Area of Science:
- Pharmacology
- Cardiology
- Clinical Therapeutics
Background:
- Cardiovascular disease (CVD) introduces pathophysiologic changes that significantly influence drug pharmacokinetics.
- These alterations necessitate careful consideration in drug therapy management for patients with CVD.
Purpose of the Study:
- To review the modifications in drug kinetics caused by cardiovascular disease.
- To elucidate the underlying mechanisms responsible for these kinetic changes.
- To outline the clinical implications for drug dosage adjustments and therapeutic choices.
Main Methods:
- Literature review examining studies on drug kinetics in cardiovascular disease.
- Analysis of pathophysiologic changes affecting drug absorption, distribution, metabolism, and excretion.
- Consideration of specific drug classes including antiarrhythmics, antihypertensives, and cardiotonics.
Main Results:
- Cardiovascular disease modifies drug kinetics through various mechanisms.
- Specific drug classes exhibit altered pharmacokinetic profiles in the presence of CVD.
- Clinical implications include the need for individualized dosage regimens.
Conclusions:
- Awareness of drug kinetic modifications in CVD is essential for clinicians.
- Knowledge of these changes provides a rational basis for selecting appropriate drug therapies.
- Adjustments in dosage regimens are frequently required for optimal patient outcomes.
Abstract:
The pathophysiologic changes occurring in cardiovascular disease can affect the kinetics of drugs in several different ways. The present review examines these modifications and the underlying mechanisms. The kinetics of specific agents, such as antiarrhythmic, antihypertensive, cardiotonic, and other drugs are considered, and the clinical implications are outlined. The clinician should be aware of these modifications, because they require an adjustment of the dosage regimen. A rational basis for a correct therapeutic choice can be provided by adequate knowledge of these modifications.
