Great improvements have been made in the treatment of heart disease
in recent years, in large part from the research and development of new,
effective medicines or drugs. (Many people misunderstand the word “drug”:
it simply means a medicine.)
These new drugs are effective because they are powerful, and if you
have been prescribed one you need to know what you are taking and how
you should take it, why you have been given it, and what effects it will have.
