CAPSULES. A convenient vehicle for administration of powders, seeds, oils, balsams, Castor oil, Garlic, Rose Hip, etc, having the advantage to mask nasty tasting or smelly medicines. Ideal for regulating dosage for children. Swallowed, they soon reach the stomach where their contents are slowly released. Gelatin capsules are of animal origin but cellulose non-animal materials are available. Their use extends also to gynaecological and rectal problems, inserted into the vagina or anus.
Standard sizes range from size 5 to 000. Size 00 is most popular in European pharmacy. See: POWDERS.
To fill empty capsules, take apart the two sections, ‘dab’ open end into powder on a flat surface; fill to capacity and affix unfilled half-shell. Manufacturers use a special filling machine for this purpose.
Patients should remain standing for at least 90 seconds after taking capsules, and followed up with sips of water. Swallowing failure is possible when capsules are taken in the recumbent position when they may adhere to the oesophageal membrane delaying disintegration time.
