Abstract

The invention discloses an amoxicillin pharmaceutical preparation and a preparation method thereof. The amoxicillin pharmaceutical preparation comprises the following components in parts by mass: 90.0-99.9 parts of amoxicillin and 0.1-10.0 parts of magnesium stearate. The preparation method is a dry-press process. By controlling the particle size distribution of amoxicillin, the particle size distribution of magnesium stearate and the pressure of the dry press, excellent dissolution quantity and stability of the amoxicillin preparation can be ensured.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular, the invention relates to amoxicillin capsules and a preparation method thereof. Background technique [0002] Amoxicillin is a broad-spectrum antibiotic. It exerts a bactericidal effect by inhibiting the synthesis of bacterial cell walls. It can quickly dissolve and rupture bacteria into spheroids. It has a strong and rapid killing effect on both Gram-negative bacteria and positive bacteria. Terminal spirochetes also have a killing effect. As the β-lactam oral antibiotic preferred by WHO, amoxicillin has good effects on infections of the respiratory system, urinary system, and digestive system. Oral dosage forms of amoxicillin include tablets, capsules, granules, dispersible tablets, etc. Among them, amoxicillin capsules are commonly used in clinical practice and are listed as a category A variety of national medical insurance. [0003] However, amoxicillin has poor sol...
