With a major in pharmacology, you could pursue a career as a pharmacologist who discovers, designs and tests drugs. Some pharmacologists extract new drugs from plants and other living sources, some design and synthesise new chemicals for use as drugs. You can find pharmacology roles in many different organisations: basic pharmacology research occurs in both universities and in pharmaceutical companies. Pharmacologists play key roles in both the conduct an analysis of these trials and in reviewing them for government before a drug is allowed on to the market. A special group of pharmacologists - toxicologists - play a particularly important role in the evaluation of the safety of drugs and other chemicals which may affect humans.
