ABSTRACT
OBJECTIVE:
To prepare compound Danshen adhesion pulsatile release pellets.METHODS:
Different coating materials were used. Swelling layer, controlled-release layer and adhesive layer were packed on drug-containing pellets from inside to outside. The coating effect on the dissolution was studied. The coating formulation was optimized. The adhesiveness of the pellets was e-valuated.RESULTS:
The release delay and rate were affected by the materials of swelling layer, controlled-release layer and adhesive layer, the weight of coating layer, and the type and quantity of plasticizer.CONCLUSION:
With the best coating prescription, a delay of 4.5 h in drug release was reached in simulated changing human gastrointestinal pH environment. The cumulative release reached more than 80% 1.5 h post the release lag, indicating a pulsatile release effect.
