Problems solved by technology

[0003] Bromacetophylline preparations that have been approved in Korea, for example, a product called surfolase (Modern Drugs) can be taken twice a day and 100 mg each time, when combined with a drug that is taken once a day or a drug that is taken once a day When comparing the medicines of three times (before and after meals), there are the following problems: the patient's medication compliance is lowered because the time point of administration is not clear, and the administration time (interval) is not specified, so the desired effect cannot be achieved. treatment effect
In order to improve drug compliance, it is preferable to develop sustained-release preparations that can produce sustained drug effects. However, in the case of slow drug effects and only sustained drug effects, such as respiratory diseases that require rapid effect In the case of certain diseases, since the effect cannot be quickly exerted after taking it, it makes the patient suffer more, and, compared with the preparations sold on the market, the desired therapeutic effect cannot be expected

Abstract

The present invention relates to a pharmaceutical composition containing acebrophylline thereby having both immediate and extended release characteristics, and more specifically, to a sustained-release pharmaceutical composition containing acebrophylline and a hydrophobic sustained-release agent.

Description

technical field [0001] The invention relates to a sustained-release pharmaceutical composition comprising bromacetate theophylline and a hydrophobic sustained-release agent. Background technique [0002] Acebrophylline (acebrophylline) is a compound synthesized by using 7-theophylline to salify ambroxol (ambroxol). It is a salt composed of an acid and a base. When administered orally, Separation into ambroxol and 7-theophylline for metabolism. Bromoacetate theophylline selectively acts on the bronchi and lung tissue to inhibit the activity of phospholipase in the bronchoalveolar and increase the surface activity of the alveoli, thereby exerting an expectorant effect. In addition, by inhibiting the formation of leukotrienes (LTs) and prostaglandins (PGs), it exerts an efficient anti-inflammatory effect, so by reducing bronchial hypersensitivity, it restores the contracted bronchi to a normal state or dilates them. [0003] Bromacetophylline preparations that have been appro...
