Abstract

The present invention provides a clenbuterol aerosol inhalation solution preparation and a preparation method thereof. The clenbuterol aerosol inhalation solution preparation comprises clenbuterol, astabilizer, an osmotic pressure regulator, an appropriate amount of a pH regulator, and water. The clenbuterol aerosol inhalation solution preparation is reasonable in compositions, uses an atomized inhalation manner to conduct direct inhalation from mouth and nose, can avoid a first-pass effect of the liver and destruction and degradation of gastrointestinal tract, greatly reduces drug metabolismprocesses of the liver and kidneys, reduces organ damages to patients, is even in drug distribution, has a drug average particle diameter of about 0.2 [mu]m and a ratio of inhalable particles as highas 74% or more, is quick in taking effect, simple in the preparation method and low in cost, and has a very good development prospect.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to a clenbuterol solution preparation for atomized inhalation and a preparation method of the clenbuterol solution preparation for atomized inhalation. Background technique [0002] With the rapid development of industry, the surrounding environmental pollution is becoming more and more serious, and the diseases caused by environmental pollution are also increasing, including chronic bronchitis, bronchial asthma and other respiratory diseases. Patients infected with this respiratory disease often have symptoms such as severe cough, thick sputum, difficulty in expectoration, and tracheal obstruction by sputum. These symptoms not only make the patient uncomfortable, but also affect sleep and even prolong the development of the disease. [0003] Clenbuterol hydrochloride is a potent selective adrenergic β2 receptor agonist, which has a strong and long-lasting effe...
