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.

Abstract

The invention belongs to the field of pharmaceutical compositions, and provides an antiasthmatic drug composition. The effective ingredients of the antiasthmatic drug composition are composed of, by mass, 5 parts of salbutamol sulfate, 1-5 parts of herba ephedra extract and 1-5 parts of semen armeniacae amarae extract. The invention further provides double-pulse controlled-release pellet capsules containing the antiasthmatic drug composition. The pharmaceutical composition combines traditional Chinese medicine with western medicine, can achieve synergistic interaction, decrease the dosage and reduce the toxic and side effects of salbutamol sulfate and generation of the drug resistance and not only can control the asthma symptoms, but also can treat root causes.

Description

technical field [0001] The invention belongs to the field of pharmaceutical compositions, in particular to a pharmaceutical composition containing extracts of ephedra and bitter almonds. Background technique [0002] Bronchial asthma (abbreviated as asthma) is a common respiratory disease, caused by bronchial smooth muscle spasm, airway obstruction, more common with bronchial asthma, asthmatic bronchitis. In recent years, the prevalence of asthma has been increasing year by year worldwide. Asthma is a chronic inflammatory disease of the airway involving a variety of cells, including inflammatory cells, structural cells and cellular components of the airway. This chronic inflammation leads to airway hyperresponsiveness, often with airway obstruction, and causes recurrent episodes of wheezing, shortness of breath, chest tightness, or coughing [0003] beta 2 Receptor agonists are the first-choice drugs to control the acute attack of asthma, mainly through the β on the surfa...
