Definitions

  • the present disclosure relates to acid resistant banding solutions for banding acid resistant two piece hard capsules, and use of such capsules for example for oral administration of at least one of pharmaceuticals, veterinary products, foods and dietary supplements to humans or animals.
  • Two piece hard capsules are the oral dosage form preferred by patients, and have traditionally been made from gelatin for more than a century. Over the past twenty years, new types of hard capsules have been developed with alternative raw materials, mainly with hypromellose and pullulan. All these capsules are of immediate release or designed for releasing their content in the stomach rapidly after administration.
  • Delayed release capsules resistant to the acid conditions of the stomach were developed early on using gelatin insolubilization by treatment with formaldehyde. See, e.g., Ridgway et al., Hard Capsule Development & Technology , The Pharmaceutical Press, 1978, p. 11.
  • enteric hard capsules (“enteric coated capsules”) became more popular on the pharmaceutical market. See, e.g., Ridgway et al., Hard Capsule Development & Technology , The Pharmaceutical Press, 1978, pp. 229 to 232.
  • the capsule itself is of immediate release, and its acid resistance is achieved by a post-manufacturing treatment of the capsule, generally after the filling of the capsule in the pharmaceutical company site.
  • DRCAPSTM capsules Further evaluation of DRCAPSTM capsules has revealed that there remains a risk under some conditions for the two parts of the capsule, body and cap, to become separated; for example, under the mechanical stress of in vitro dissolution testing, notably during the in vitro disintegration test under acid conditions. Similarly, diffusion of dissolution medium into the closed capsule and/or diffusion of content from the capsule through the gap between body and cap remain a risk.
  • Another method to decrease leakage is to seal the cap and the body of the capsule directly to each other by means of a “sealing fluid.” See, e.g., U.S. Pat. No. 3,071,513; U.S. Pat. No. 2,924,920; FR 2,118,883, EP 0152517; U.S. Pat. No. 4,756,902; FR 2 118883; EP 0152517; and U.S. Pat. No. 4,756,902.
