preparation example Construction

[0032] The preparation method for preparing the colon-targeted drug delivery preparation of the cardiac muscle protein polypeptide of the present invention comprises the following steps: the first step is to prepare the medicinal powder containing the myocardial protein polypeptide component; the second step is to place the medicinal powder in a centrifugal coating granulator, Spray sucrose syrup to moisten the drug powder, control the spray flow rate, and dry by blowing air to obtain a 60-80-mesh ball core; the third step is to use the ethanol solution of vidpodone K30 as a binder, and use the powder supply machine to spray the ball core Drug powder, control the feed ratio of binder and drug powder, increase the pellet core to 10-3000μm pellets, dry and sieve to obtain the drug-containing pellets; the fourth step, put the drug-containing pellets in a centrifugal bag In the coating granulator, spray the coating solution prepared according to the prescription to the pellets, con...

Embodiment 1

[0035] Take 10 kg of fresh pig heart, add 5 times of 0.9% normal saline, homogenate at high speed, add 20 liters of petroleum ether to degrease three times while stirring, separate the liquid and discard the ether layer, take the degreased solution to adjust to pH 1.5, add appropriate amount of pepsin, Hydrolyze at 37°C for 6 hours, adjust to pH 7.5, add appropriate amount of trypsin, hydrolyze at 37°C for 6 hours, centrifuge at high speed, take supernatant and concentrate by ultrafiltration, collect polypeptide concentrate with molecular weight cut-off less than 10,000 Daltons, add mannitol The excipients were lyophilized to obtain 2.2 kg of off-white polypeptide lyophilized powder.

Abstract

The invention discloses a colon specific targeting drug-delivery preparation of myocardial protein polypeptides and its preparing process, wherein the preparation is prepared through coating the drug-containing micro-pellets made from medicinal powder containing myocardial protein polypeptides components with colon targeting coating layer liquid, or directly loading the drug-containing micro-pellets into the shells of the colon targeting capsule. The process for preparing the colon targeting drug-delivery preparation of the myocardial protein polypeptides consists of producing drug-containing micro-pellets containing myocardial protein polypeptides components, then preparing the colon targeting coating liquid, finally coating the drug-containing micro-pellets with the colon targeting coating liquid. The preparation provided by the invention can make the colon release drugs enter blood circulation through colon, thereby avoiding metabolism destruction of the conventional oral preparation peptides drugs on the stomach, as a result, the therapeutic action of the drugs can be sufficiently exploited.

Description

technical field [0001] The invention relates to a colon-targeting preparation, in particular to an active cardiac protein polypeptide colon-targeting preparation for improving cardiovascular system diseases and increasing myocardial oxygen utilization function and a preparation method thereof. Background technique [0002] Studies have shown that there are about 120 million myocarditis patients in my country at present. Animal myocardial protein hydrolyzate is an effective therapeutic ingredient for such diseases. Myocardin polypeptide is a small molecular polypeptide produced by hydrolysis of animal heart, and its main components are atrial peptide, calcitonin gene-related peptide and other special small molecular polypeptides. Atrial peptide (ANP) has strong natriuretic, diuretic, vascular smooth muscle relaxation and inhibition of renin-angiotensin-aldosterone. The main part of ANP is the beginning and end of the nephron, that is, the glomerulus And the inner medullary ...
