Embodiment 1
[0042] Embodiment 1 double-pulse controlled-release pellet capsule
[0043] Table 1, embodiment 1 prescription
[0044]
[0045]
[0046] Preparation
[0047] 1) Extraction of Chinese medicinal materials:
[0048] Ephedra was extracted with 5 times the amount of 0.001mol / L hydrochloric acid ethanol, refluxed 4 times, each time for 1h, the extract was concentrated, dried and pulverized. Bitter almonds are crushed into coarse powder, extracted with 8 times the amount of 90% ethanol (mass fraction, the same below) under reflux for 1.5 h, the extract is concentrated, dried and pulverized.
[0049] 2) Micropill 1 preparation: get the active ingredient (principal drug) mixture of the mixed albuterol sulfate, ephedra extract and bitter almond extract, make the ball core with 80% ethanol together with the ball core auxiliary materials, and use 4% swelling material coated with ethanol solution and dried to obtain skeleton type sustained-release pellets 1.

[0054]
[0055]
[0056] 2. Preparation method
[0057] 1) Extraction of Chinese medicinal materials:
[0058] Ephedra was extracted with 6 times the amount of 0.001mol / L hydrochloric acid ethanol, refluxed for 3 times, each time for 1.5h, the extract was concentrated, dried and pulverized. Bitter almonds are crushed into coarse powder, extracted with 7 times the amount of 95% ethanol under reflux for 1 hour, the extract is concentrated, dried and crushed.
[0059] 2) Micropill 1 preparation: take the mixed main drug mixture of salbutamol sulfate, ephedra extract and bitter almond extract, make a pellet core with 80% ethanol together with the pellet core auxiliary materials, and wrap it with 4% ethanol solution of swelling material coat and dry to obtain skeleton type sustained-release pellets 1.
