Explain pharmacology
It isn't normal to administer a pure drug to a patient. Nearly all drugs are administered in the form of a medicine. A medicine is a mix of one or more drugs combined or formulated with other inactive materials known as excipients. Explain excipients themselves have no pharmacological activity however do have a major influence on how the drug is administered and absorbed. The preparation of a drug into a medicine - whether it be in tablet, ointment, injection form or some kind of liquid solution - is typically essential before it can be administered to humans. Each medicine is a extremely sophisticated product carefully designed to fulfil its purpose to safeguard that the response to the medicine is the same each time it is administered.
The colour as well as shape of tablets and capsules are controlled as an aid to identification. Charts are available which permit us to identify all drugs sold as proprietary preparations. The colour of tablets as well as capsules is as well used by manufacturers as a psychological means of increasing the drug's effect. If you look at one of the several drug identification charts available in your hospital pharmacy you will notice that the capsules that contain tranquillisers are in subdued, quiet insignia (such as dark greens, blues and even blacks), while the capsules for antidepressants have vibrant insignia (such as yellows and reds). These colour groupings are a subtle attempt to enhance the therapeutic effects of the medicine as well as constitute an example of using the ‘placebo' effect in drug administration.
