written. Antibiotics are the most widely prescribed class of drugs in the world. In the
developed world, heart drugs are the most widely prescribed class, partly because they
are generally taken for the remainder of the patient’s life. In recent years, prescriptions
for psychotropic drugs have decreased as doctors have become more aware of problems
associated with addiction, and prescriptions for asthma have increased, reflecting a
greater incidence (or awareness) of the disease. The U.S. market accounts for 50% of
pharmaceutical sales. The aging U.S. population (by 2005, nearly 30% will be over 50
years old) will lead to increased demand for treating conditions such as high cholesterol
levels, hypertension, diabetes, osteoarthritis, and menopause symptoms.
Throughout this book we have encountered many drugs, vitamins, and hormones,
and in many cases we have discussed the mechanism by which each compound
produces its physiological effect. Table 30.2 lists some of these compounds, their uses,
and where in the text they are discussed. Now we will take a look at how drugs are
discovered and how they are named, and we will examine some of the techniques
currently used by scientists in their search for new drugs.

30.1 Naming Drugs
The most accurate names of drugs are the chemical names that define their structures.
However, these names are too long and complicated to appeal to physicians or the
general public. The pharmaceutical company is allowed to choose the proprietary
name for a drug it develops. A proprietary name (trade nameor brand name)iden-
tifies a commercial product and distinguishes it from other products. A proprietary
name can be used only by the owner of the registered trademark, which can be a
