Problems solved by technology

Longer et al. used bioadhesion to combine chlorothiazide and albumin to make drug-containing albumin particles, which were mixed with polycarbomer (PCP, 3:7) particles and loaded into capsules. The in vivo dissolution showed that the capsules could be released continuously. Drug 8h, but release more than 60% within 2h

Abstract

The invention belongs to the novel technical field of medicaments, and relates to a novel dosage form of amoxicillin used for treating: 1, upper respiratory tract infections, such as tympanitis, nasosinusitis, pharyngitis and tonsillitis resulted from streptococcus hemolyticus, streptococcus pneumoniae, staphylococcus or haemophilus influenzae; 2, genitourinary tract infections resulted from escherichia coli,proteus mirabilis or enterococcus faecalis; 3, skin and soft tissue infection resulted from streptococcus hemolyticus, staphylococcus bacteria or escherichia coli; 4, lower respiratory tract infections, such as acute bronchitis and pneumonia, resulted from streptococcus hemolyticus, streptococcus pneumoniae, staphylococcus bacteria or haemophilus influenzae; 5, acute simple gonorrhea; and 6, typhoid, typhoid bacteria-carrier, leptospirosis and the like. The novel dosage form is characterized in that the stomach floating tablet is hydrated into gel on the surface to expand the volume thereof after contacting with the gastric juice at the body temperature because of a plurality of hydrophilic macromolecular materials contained. Meanwhile, the weight of the tablet is less than the buoyant force of the gastric juice to float the tablet on the gastric juice and prolong the retention time in the stomach.

Description
