a. Categories of cardiovascular drugs can be prescribed for more than one purpose (e.g., beta-blockers may be used to treat hypertension but also treat angina), whereas individual drugs within categories (e.g., atenolol) may be better known to be used for a specific purpose. The drugs in this category were known to be used primarily as antihypertensives.
