Petition to Require a Warning on All Calcium Channel Blocking Drugs – Public Citizen
The purpose of giving drugs to control high blood pressure is to prevent stroke, heart attack, heart failure and premature death, not simply to lower blood pressure. In addition, to alleviate symptoms the purpose of treating chest pain is to slow or halt progression of coronary artery disease and reduce the risk of heart attack, heart failure or death.
2. No well controlled study has shown convincingly that calcium channel blockers can reduce stroke, heart attack, heart failure or prevent death.
3. The best available scientific evidence links calcium channel blockers to an increased risk of heart attack and death in people using these drugs for high blood pressure and chest pain.
4. The calcium channel blocking drugs are often prescribed for the life of the patient.
5. Although the calcium channel blockers are chemically different, they all share mechanisms of action.
