Description

Nicorandil orally disintegrating tablet and preparation method thereof
Technical Field
The invention relates to the field of pharmaceutical preparations, in particular to a nicorandil orally disintegrating tablet and a preparation method thereof.
Background
Nicorandil, chemical name is N- (2-hydroxyethyl) nicotinamide nitrate, molecular formula is C8H9N3O4The ATP sensitive potassium ion channel opener is the first ATP sensitive potassium ion channel opener used in clinic. Clinical studies prove that nicorandil is suitable for various types of angina, including exertional angina and spastic angina, and can remarkably reduce the occurrence risk of cardiovascular events and improve prognosis. Nicorandil has the functions of preventing intracellular calcium ion from dissociating, increasing permeability of cell membranes to potassium ions, expanding coronary vessels, continuously increasing coronary blood flow and inhibiting coronary artery spasm, does not influence blood pressure, heart rate, myocardial contractility and myocardial oxygen consumption when expanding the coronary vessels, and also has the functions of inhibiting platelet aggregation and preventing thrombosis.
Orally Disintegrating Tablets (ODT) are a new type of oral dosage form. The preparation can be rapidly disintegrated in oral cavity under anhydrous condition (or only a small amount of water exists), enters digestive tract along with swallowing, is absorbed in oral cavity without mucosa, and has the same absorption and metabolism process as common tablet. Compared with the common preparation, the ODT has the advantages of convenient administration, small irritation to digestive tract mucous membrane, and the like. A significant proportion of elderly or stroke patients have dysphagia (dysphagia), and many have persistent problems. This may lead to reduced patient compliance when such patients are given an oral formulation that must be swallowed intact. Other patients may also suffer from dysphagia as they are common in all age groups and are observed in approximately 35% of the general population and up to 60% of all patients in the institutional care (institutionalized) population and long-term care facilities in approximately 20%.
However, nicorandil has poor stability, needs to be stored below 10 ℃, has activity in a crystal state, is prepared into the rapidly disintegrating oral tablet from nicorandil, is produced and stored at normal temperature, has preparation procedures such as tabletting and the like, has the problem that the active ingredients of the prepared nicorandil are reduced due to easy damage and inactivation of crystal forms in the preparation process, has the risk of instability and failure of the nicorandil, and simultaneously can become unstable along with the storage time, and at present, no related patent of the preparation method of the nicorandil orally disintegrating tablet exists in China.

Test solution: taking 20 tablets of the product, precisely weighing, grinding, taking a proper amount of fine powder (about 20mg equivalent to nicorandil), putting the fine powder into a 50ml measuring flask, adding 30ml of solvent, shaking for 10min, diluting with the solvent to scale, shaking uniformly, filtering, precisely weighing 5ml of subsequent filtrate, putting the subsequent filtrate into a 25ml measuring flask, diluting with the solvent to scale, and shaking uniformly.
Control solution: taking 20mg of a reference substance, placing the reference substance in a 50ml measuring flask, dissolving and diluting the reference substance to the scale mark by using a solvent, precisely measuring 5ml of the reference substance, placing the reference substance in a 25ml measuring flask, diluting the reference substance to the scale mark by using the solvent, and shaking up.
Chromatographic conditions are as follows: octadecylsilane chemically bonded silica is used as a filling agent; acetonitrile-water (25:75) is used as a mobile phase; the detection wavelength is 254 nm; the flow rate is 1 ml/min; the injection volume is 20 mul; the solvent was 80% methanol.
The determination method comprises the following steps: precisely measuring 20 μ l of each of the test solution and the reference solution, respectively injecting into a liquid chromatograph, recording chromatogram, and calculating according to external standard method by peak area.
And (3) investigating long-term stability test:
samples of the commercial preparations of the examples and the comparative examples are placed at a temperature of 25 +/-2 ℃, are sampled and analyzed after being placed for 0 month, 3 months and 6 months, and the properties, related substances, contents, content uniformity and disintegration time limit of the samples after being placed are measured and calculated, and the results are shown in table 1.

Accelerated stability test investigation:
the samples of the examples and the comparative examples are placed at the temperature of 40 +/-2 ℃, are sampled and analyzed after being placed for 0 month, 3 months and 6 months, and the properties, related substances, content uniformity and disintegration time limit of the samples after being placed are measured and calculated, and the results are shown in table 2.

Experimental example 2
In example 1, nicorandil orally disintegrating tablets of 5mg size and a commercially available formulation, xghamel nicorandil tablet (size: 5mg, trade name:
Figure BDA0003566287820000153
xige mai, manufacturing enterprise: nipro Pharma Corporation kagamisishi Plant) in a single-site, randomized, open, single (fasting/postprandial n ═ 12) oral administration, two-formulation, two-sequence, two-cycle, crossover human bioequivalence test, using the following amounts: orally administered 1 tablet with 240ml warm boiled water. The pharmacokinetic parameters obtained (AUC0-t, AUC0- ∞, Cmax) were statistically analyzed and evaluated 12h after the time of administration. The fasting and postprandial drug time curves of the nicorandil orally disintegrating tablet and the nicorandil tablet with the same specification in figure 1 and figure 2 result in that the two drugs have a living bodyAnd (4) physical equivalence.
Although the invention has been described in detail hereinabove with respect to a general description and specific embodiments thereof, it will be apparent to those skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
