Problems solved by technology

[0003] Due to the short half-life of amoxicillin in the body and the rapid excretion through the urinary tract, the drug availability is low. The time to peak blood concentration after taking the drug is about 2 hours. Ingestion of drugs can maintain blood drug concentration. Generally, amoxicillin drugs are used frequently. Therefore, how to improve the sustained-release effect of amoxicillin, reduce the number of times of taking drugs, and improve drug utilization has become a problem that needs to be solved.

Abstract

The invention discloses an amoxicillin capsule and a preparation method thereof, the content of the amoxicillin capsule is a sustained-release pellet, and the sustained-release pellet is composed of the following raw and auxiliary materials by weight: 80%-95% of amoxicillin, 0-5% of a molding material, 2-15% of a sustained-release coating material, 0.5-3% of a plasticizer, 1-6% of an anti-sticking agent and 2-5% of a pore-foaming agent. According to the present invention, the sustained and controlled release effect is good, the bioavailability is high, such that the stable blood concentration is maintained, the medication frequency is reduced, the raw materials are easily available, the preparation process is simple and feasible, the yield is high, the cost is low, the industrial large-scale production can be achieved, and the significant economic benefits are provided.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to an amoxicillin capsule and a preparation method thereof. Background technique [0002] Amoxicillin is suitable for upper respiratory tract infections such as otitis media, sinusitis, pharyngitis, tonsillitis, etc. bacteria, Proteus mirabilis or Enterococcus faecalis, acute bronchitis, pneumonia and other lower respiratory tract infections caused by hemolytic streptococcus, Streptococcus pneumoniae, staphylococcus or Haemophilus influenzae, acute simple gonorrhea, etc. It has a good antibacterial effect on severe infections of the upper and lower respiratory tracts. Its preparations include capsules, tablets, granules, dispersible tablets and the like. [0003] Due to the short half-life of amoxicillin in the body and the rapid excretion through the urinary tract, the drug availability is low. Ingestion of drugs can maintain blood drug concentration, and the...
