ABSTRACT:
Knurled surfaces such as raised ribs are provided on the shell of a soft gelatin capsule in order to enhance gripping and manipulation of the capsule. The capsule has a removable tab at one end thereof which may also be provided with a knurled surface. One embodiment of the invention is a capsule used for delivery of medicaments to an external body surface. An alternative embodiment of the capsule is disclosed for insertion into a body orifice. The composition of the capsule includes a starch or starch derivative which gives the capsule a drier feel and increases the coefficient of friction of the surface of the shell, further improving the capsule's handling characteristics.
