Problems solved by technology

Although there is also a precedent for treating hypertension with traditional Chinese medicine acupoint catgut embedding therapy, using sheep catgut and traditional Chinese medicine, but there is rejection in the body. Although the treatment effect is good, it cannot achieve long-term blood pressure stabilization and bring side effect
Another patent application No. 201410402016.5 is a biodegradable subcutaneous implant stick for long-term antihypertensive treatment. Although the carrier is also biodegradable, the drug release is slow after subcutaneous implantation, and it takes a week to reduce blood pressure. The degradation time is short, usually one year About half of it is completely degraded, and another surgical injection is required, which again increases the patient's surgical pain

Abstract

The invention discloses a subcutaneous implant line for long effect pressure lowering. The implant line is prepared from raw medicine of lacidipine, aldactone and indapamide and auxiliary materials ofcrosslinked povidone, polyethylene glycol and sodium carboxymethyl starch. The implant line is a cylindrical implant line prepared by mixing biodegradable materials as carriers and hypotensive medicine. The pressure lowering speed is high; the blood pressure can be stable after implantating for 3 days; the goal of stabilizing the blood pressure for a long time can be achieved. In addition, the degradation is slow; the complete degradation can be completed after about 3 years; the line implant line use time is long; the frequent operation implantation is not needed; the operation pain of patients is reduced.

Description

technical field [0001] The invention relates to a subcutaneous slow-release drug implanting thread, which is implanted under the skin and treats corresponding diseases according to the pharmacological properties of drugs mixed in the implanting thread, specifically a long-acting antihypertensive flexible Subcutaneous thread implantation for the treatment of hypertension. Background technique [0002] At present, the treatment of hypertension at home and abroad mostly relies on oral antihypertensive drugs to maintain normal and stable blood pressure. The drug has a short duration of action, and it needs to be taken orally once or twice a day. Taking a large amount of antihypertensive drugs orally has great side effects, causing systemic and gastrointestinal reactions and great damage to liver and kidney functions. Although there is also a precedent for treating hypertension with traditional Chinese medicine acupoint catgut embedding therapy, using sheep catgut and tradition...
