Cardiotoxicity of Non Cardiovascular Drugs

Some drugs which are not aimed at treating heart disease have nevertheless been found to have profound effects on heart muscle. Cardiotoxicity is one of the major forms of toxicity seen in drugs and it accounts for most drug recalls and delays experienced in regulatory approvals.I n recent years a number of non-cardiac blockbuster drugs such as terfenadine have been withdrawn from major markets because of cardiotoxicity concerns, while other drugs have either been withdrawn prior to marketing or required labelling changes that significantly restricted their use.
