Insights
Calcium antagonists are effective for hypertension and angina but may increase mortality risk. Short-acting nifedipine should be avoided; further trials will clarify risks of other calcium antagonists.
Area of Science:
- Cardiology
- Pharmacology
Context:
- Calcium antagonists are widely prescribed for hypertension and angina pectoris.
- They offer good efficacy with fewer metabolic side effects compared to beta-blockers and diuretics.
- Unlike beta-blockers and diuretics, their impact on mortality from myocardial infarctions and strokes is not well-established.
Purpose:
- To discuss potential harmful mechanisms of calcium antagonists.
- To evaluate risks associated with different classes and formulations of calcium antagonists.
- To review evidence regarding calcium antagonists and mortality from myocardial infarctions and strokes.
Summary:
- Meta-analyses from 1995 suggest certain calcium antagonists may increase mortality.
- Short-acting nifedipine formulations are implicated and should be withdrawn from therapy for chronic hypertension and angina pectoris.
- The paper examines pathogenetic mechanisms and drug-specific effects, including duration of action.
Impact:
- Highlights the need for caution with specific calcium antagonist formulations.
- Suggests potential risks associated with calcium antagonists, contrasting with established benefits of other drug classes.
- Ongoing trials are crucial to determine the overall safety and utility of various calcium antagonists in cardiovascular therapy.
Abstract:
Calcium antagonists are widely used in therapy of hypertension and angina pectoris. Their advantage is good efficacy, relatively few and not dangerous side effects and first of all lack of bad metabolic effects (hypokalemia, hyperuricemia, hyperinsulinemia and hyperlipoproteinemia). In contrast to beta-blockers and diuretics, which decline mortality from myocardial infarctions and strokes there are not similar information concerning calcium antagonists. Two meta-analysis from 1995 unexpectedly suggest, that some preparations of calcium antagonists increase mortality from myocardial infarctions and strokes. In our paper we discuss possible pathogenetic (harmful) mechanisms, pay attention to each class of calcium antagonists and time of action of the particular drugs. Short acting nifedipine formulation should be withdrawn from chronic hypertension and angina pectoris therapy. Ongoing multicenter trials in several European countries and in USA will decide the usefulness of other calcium antagonists preparations.
