Abstract
A novel capsule-like medicament and method for producing such medicaments are disclosed. The method provides a procedure for coating solid cores, such as caplets, with a first gelatinous coating on one end, and then with a second gelatinous coating on the other end which is thicker than the first, to simulate the interlocking halves of a hollow capsule. The second, thicker gelatinous coating can be provided with a single gelatin coating from a bath having a higher viscosity than the bath used to provide the first gelatinous coating. Alternatively, the second gelatinous coating can be provided by double dipping to provide layers of gelatinous material or gelatin.
Claims45
A method for coating a caplet with a gelatinous coating to produce a simulated capsule-like medicament comprising:
- (a) providing a holding means having a caplet channel defined therein;
- (b) inserting a first end of said caplet into said caplet channel while leaving a second end of said caplet exposed;
- (c) applying a gelatinous coating to said second exposed end of said caplet;
- (d) permitting said gelatinous coating to dry to form a coated second end;
- (f) applying a first gelatinous coating to said first end of said caplet, said gelatinous coatings on said first and second ends substantially covering said caplet;
- (g) permitting said first gelatinous coating on said first end to dry;
- (h) applying a second gelatinous coating to said first end of said caplet;
- and
- (i) permitting said second gelatinous coating on said first end to dry;
- said first and second gelatinous coatings on said first end forming a thicker gelatinous coating than that applied to said second end.
A simulated capsule-like medicament comprising:
- (a) a solid caplet having a first and second end, said caplet comprising a generally cylindrical shape;
- (b) a first gelatinous coating provided on said second end of said caplet;
- and
- (c) a second gelatinous coating provided on said first end of said caplet, said second gelatinous coating having a greater thickness than the thickness of said first gelatinous coating to form a simulated capsule-like medicament with a seam circumscribing the medicament about a midway point of a longitudinal axis of the medicament.
