Drug is one of the medical profession''s most valuable tools.  Doctors prescribe drugs to treat or prevent many diseases.  Every year, penicillin and other germ-killing drugs save the lives of countless victims of meningitis, pneumonia, and other dangerous infectious diseases.  Vaccines prevent such diseases as measles, polio, and smallpox.  Analgesics lessen or eliminate pain.  The use of these and many other kinds of drugs has helped millions of people live longer, healthier lives than would otherwise have been possible.
