RESIN PARTICLE, MEDICAL MATERIAL AND PHARMACEUTICAL PREPARATION CONTAINING SAID RESIN PARTICLE |
摘要 |
A resin particle is provided which comprises an ethylene vinyl alcohol copolymer and 5 to 90 % by weight of cilostazol incorporated therein, and has a particle size of not greater than 2,000 .mu.m. The resin particle, upon being administered orally, allows the concentration of cilostazol in blood to be kept constant over an extended period of time and, therefore, remarkably alleviates side effects such as pain and headache which may otherwise be caused by rapid release of cilostazol into a body.
