E-numbers
Drug names
Medicines normally have more than one name -
• a generic name, which is the active ingredient of the medicine,
• a brand name, which is the trade name the manufacturer gives to the
medicine.
The generic name is the official medical name for the active ingredient of
the medicine.
The brand name is chosen by the manufacturer, usually on the basis that
it can be recognised, pronounced and remembered by health professionals
and members of the public. An example would be Viagra - this is the
well-known brand name given by Pfizer to the generic medicine sildenafil.
(Brand names are capitalised; generic names are not.)
E-numbers
The ubiquitous "E-numbers" rear their head in the coatings of some
medications, specifically Dutasteride, which contains E321, E172 and E171.
Other medications may also contain E-numbers, only I may not have found
the reference to them yet.
E-numbers are codes for substances which can be used as food additives for
use within the European Union, with the "E" standing for "Europe". They
are commonly found on food labels throughout the European Union. Safety
assessment and approval are the responsibility of the European Food Safety
Authority (wikipedia, 2014b).
Having a single unified list for food additives was first agreed upon in 1962
with colours. In 1964, the directives for preservatives were added, 1970 for
antioxidants and 1974 for the emulsifiers, stabilisers, thickeners and gelling
agents.
