Abstract

The invention discloses externally-applied powder for treating rheumatic arthralgia and a preparation method thereof, which belong to the field of medicines for treating rheumatic arthralgia. The externally-applied powder solves the technical problem that the conventional medicines for treating rheumatic arthralgia are inconvenient. The externally-applied powder comprises a medicine bag and a medical adhesive tape, wherein the peripheral parts of the breathable material and unbreathable material of the medicine bag are adhered; the central parts of the breathable material and the unbreathable material of the medicine bag are separated to form a cavity; and medicine powder is filled in the cavity. In the invention, the externally-applied powder for treating rheumatic arthralgia is prepared by using an extraction and purification process and by concentrating, filtering, removing ineffective ingredients and enriching active ingredients in caulis sinomenii and powdered Stephania tetrandra, filling in the cavity formed by the breathable material and unbreathable material to obtain the medicine bag and packing the medicine bag and the medical adhesive tape together. The medicines in the externally-applied powder directly act on affected parts for a long time; the medicines are released slowly, so the medicine effect lasts for a long time; the side effects of gastrointestinal tract irritation, poor absorption, first pass effect of hepar and metabolite are avoided; and medicine administration times can be reduced obviously and pollution to clothes is avoided.
