Abstract
The present invention utilizes ultramicropulverization and dripping pill preparation production process to make nicorandil dripping pills, and can attain the goal of raising disintegration and dissolution speed, quickly obtaining therapeutic effect, raising production cost and convenient administration. Said pill not only can be sucked, but also can be swallowed, and its compliance property is good.
Description
Technical field
The present invention relates to a kind of pharmaceutical product and preparation method thereof, specifically nicorandil drop pill and preparation method thereof.
Background technology
Nicorandil is an anti-anginal drug, belong to nitrate compound, it is free to have the intracellular calcium of prevention, increase the permeability of cell membrane to potassium ion, the expansion coronary vasodilator, the persistence coronary blood flow increasing suppresses the effect of coronary vasospasm, when the expansion coronary vasodilator, do not influence blood pressure, heart rate, myocardial contraction and myocardial oxygen consumption.Nicorandil also has anticoagulant and prevents thrombotic effect.
The nicorandil oral absorption is fast, and bioavailability is 7 5% and complete, 0.5～1 hour blood drug level peaking in back of taking medicine, half-life (t
1/2) be about 1 hour.Mainly be distributed in liver, the heart, kidney, adrenal gland and the blood.Slough nitro through hydrolysis in vivo, the metabolite pharmacologically active is very little, mainly drains from urine.List marketing at present tablet, the clinical treatment that is used for coronary heart disease, angor only arranged.
The nicorandil bitter in the mouth, molten in the water part omitted, its disintegration of tablet time is long, dissolution and dissolution rate are low, absorption difference, and bioavailability is low, the supplementary product consumption ratio is big, child, old people, bed patient and dysphagia patients are taken inconvenience, and compliance is poor, have influenced the performance of nicorandil therapeutical effect.
The present invention makes the nicorandil drop pill by using ultramicro communication technique and dropping pill formulation Technology exactly, thereby overcomes the above defective of nicorandil tablet, and the therapeutical effect of nicorandil is given full play to.
Summary of the invention
The nicorandil drop pill of making by using ultramicro communication technique and dropping pill formulation Technology not only have disintegrate molten loose fast, dissolution and dissolution rate improve, steady quality, the pill volume is little, easy to carry and use, onset is rapid, compliance is good, be particularly suitable for the characteristics that child, old people, bed patient and dysphagia patients are taken, but also has working condition and production equipment is simple, production cost is low, compares the advantage that supplementary product consumption reduces with tablet, has demonstrated fully the new drug research exploitation spirit that people-oriented.
For achieving the above object, the present invention by the following technical solutions: the nicorandil fine powder of 1 weight portion through micronizing is added in 1～10 weight portion molten matrix, abundant mixing, dropping preparation method is condensed into ball in coolant, remove coolant, drying, promptly.
The chemical name of nicorandil among the present invention (Nicorandil) is N-(2-hydroxyethyl) Nicorandil, and structural formula is
Molecular formula is C
