There are a
number of reasons. The manufacturers take into account the properties of medicines first. Chemical properties of some medicinenhange and efficacy reduce on their being
exposed to humidity or oxygen in the
air. Doses of such medicines have to be packed in capsules. A capsule also becomes necessary in case of bitter dose. If tablet form is essential then that
tablet has to be coated with a
tasteless material. Whether digestive system has to assimilate the dose immediately or gradually in the stomach is
also an important matter to be considered. A dose meant to be
assimilated gradually is best administered
in the form of a hard tablet because capsule ordinarily
made from gelatine is quickly dissolved by
the acidic gastric juices of the stomach.
It is possible to give this kind of dose in capsule also
provided that the dose is in granular form
and not in powder form. In such a case overriding medical reason is
assimilation of the dose in small quantities spread over a long period rather
than assimilation of the entire dose in a few minutes.
