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 thickner than the first, to simulate the interlocking halves of a hollow capsule. The second, thicker gelationous 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.
