Abstract

The invention relates to a pellet medicine combination containing valsartan, amlodipine and hydrochlorothiazide, which is characterized by simultaneously containing three active ingredients, namely valsartan, amlodipine and hydrochlorothiazide. The active ingredients of valsartan, amlodipine and hydrochlorothiazide and medicine acceptable additives are together prepared into pellets, and the pellets containing medicines are coated with coating layers with different colors. Each pallet is composed of a pellet core and a coating layer, and the pellet combination can be further made into pellet capsules. The pellet medicine combination has the advantages that the medicine can be scattered in gastrointestinal tract fast, has low thrill on the gastrointestinal tract and is even and complete in absorption and high in bioavailability, a pellet capsule casing is free of bitter taste and the like. The obtained preparation can be controlled in quality easily and is good in stability and suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of medicines, and more precisely relates to a drug combination of pellets containing active ingredients valsartan, amlodipine and hydrochlorothiazide. Background technique [0002] According to statistics, about 25% of the world's population suffers from hypertensive disorders, and the control rate of blood pressure is not ideal, and the rate of achieving blood pressure control with unilateral drugs is less than 50%. Years of clinical practice have proved that 50% of hypertensive patients need combined medication or compound prescription. The US Health and Nutrition Examination and Review Board reported that only 27% of patients diagnosed with hypertension can control their blood pressure below 140 / 90mmHg. At present, guidelines from all over the world recommend the use of multi-drug combination regimens, and combined drug use has become a common clinical antihypertensive strategy. Most hypertensive patien...
