Description
Technical field
The present invention relates to field of pharmaceutical preparations, be specifically related to a kind of slow releasing preparation that contains ambroxol hydrochloride and clenbuterol hydrochloride, and the method for preparing of said slow releasing preparation.
Background technology
Respiratory system disease is a kind of commonly encountered diseases, frequently-occurring disease, and higher sickness rate is worldwide all arranged, and the trend of increase is arranged, and it is China human mortality's a second largest factor.The cardinal symptom of respiratory system disease is cough, expectoration and asthma, but alternative clinically medicine is also few and onset is slower.
Clenbuterol hydrochloride is a kind of selective ' beta '3 adrenergic beta 2 receptor agonist of strong effect, can the diastole bronchial smooth muscle, and its bronchiectatic activity is stronger 100 times than salbutamol, and faint to the cardiovascular system influence.Except that relievining asthma, clenbuterol hydrochloride also has the bronchus of enhancing cilia activity ability, promotes sputum to discharge, helps to improve the curative effect of relievining asthma.Clenbuterol hydrochloride is used for the respiratory system disease treatment and has rapid-action, the characteristics such as length, suitable dose is little, toxic and side effects is low of holding time.
Ambroxol hydrochloride is the respiratory mucus regulator of a new generation, has the superior usefulness of eliminating the phlegm, and can reduce airway resistance, thereby reduce mucous adhesive force through increasing the generation and the secretion of pulmonary surfactant, promotes the mucociliary transhipment.The clinical various acute and chronic respiratory tract diseases that are used for expectoration and too much mucus secretion more.Safe in utilization, better tolerance, determined curative effect is reused no drug accumulation.In addition; Ambroxol hydrochloride can also promote pulmonary surfactant to secrete in a large number, and the covering protection airway epithelial cell makes antibacterial can not directly touch the respiratory tract surface; Reduce the danger that infects and promote the phagocytosis of macrophage, play the effect of prevention respiratory tract infection antibacterial.
With the compound preparation that anti-asthmatic clenbuterol hydrochloride and expectorant ambroxol hydrochloride are formed, can bring into play expelling phlegm for arresting cough and antasthmatic effect simultaneously, be used for cough-relieving, reduce phlegm, relieving asthma.The domestic existing listing at present of above-mentioned compound preparation is like compound ambroxol sheet, the special sieve oral liquid of ammonia bromine etc.The shortcoming of these preparations is that it is common compound preparation, and action time is short, needs administration 2～3 times in one day, and patient's compliance is relatively poor; And blood concentration fluctuation, be prone to cause untoward reaction.
Therefore, in order to overcome above-mentioned shortcoming, research has simultaneously relievings asthma and the double effects and have the medicine of slow release effect of eliminating the phlegm, and the lung functions index that is used to improve the patient has crucial meaning particularly for the treatment of chronic respiratory system diseases.
