Abstract

An orally-taken composite emulsion of Chuanhuning is prepared from Chuanhuning, surfactant as emulsifier, organic solvent as coemulsifier and oil. It has higher biologic utilization rate.

Description

Invention field [0001] The invention relates to an oral andrographolate emulsion composition with high bioavailability. Background technique [0002] Andrographis paniculata is a dehydroandrographolide succinate half monopotassium salt prepared from the active ingredient andrographolide extracted from the leaves of Andrographis paniculata and succinic anhydride. It is a good antiviral drug with antibacterial, antipyretic and anti-inflammatory effects. It has inactivation effect on influenza virus, respiratory virus, adenovirus, etc., and has obvious inhibitory effect on Staphylococcus aureus, Streptococcus, Escherichia coli, etc. It is often used clinically to treat exogenous fever, acute infectious diseases, urinary tract infections, etc. The curative effect is good, no skin test is needed, and the side effects are few, especially those who are allergic to antibiotics should be the first choice, so it is widely used in clinical practice. However, currently there is only an injec...
