Description

Sodium ferulate controlled release tablet and preparation method thereof
Technical Field
The invention belongs to the technical field of pharmaceutical preparations, and particularly relates to a sodium ferulate controlled release tablet and a preparation method thereof.
Background
Sodium ferulate is sodium ferulate extracted from rhizoma Ligustici Chuanxiong and radix Angelicae sinensis, and has chemical name of 3-methoxy-4 hydroxy cinnamic acid sodium salt dihydrate, and molecular formula C10H9NaO4·2H2O; ferulic acid is a vascular endothelium protective agent, can remove free radicals, prevent and treat lipid peroxidation injury, antagonize vasoconstriction, pressure rise and vascular smooth muscle cell proliferation caused by endothelin, and relieve vascular endothelium injury; increase NO synthesis, relaxation of vascular smooth muscle; inhibiting platelet aggregation, resisting blood coagulation, and improving hemorheology. It also has effects in inhibiting cholesterol synthesis, reducing blood lipid, influencing complement, enhancing immunity, and relieving pain and spasm. It is mainly used for the adjuvant treatment of vascular diseases such as atherosclerosis, coronary heart disease, cerebrovascular disease, glomerular disease, pulmonary hypertension, diabetic angiopathy, and vasculitis, and also can be used for the treatment of migraine and vascular headache.
At present, sodium ferulate preparations for clinical application comprise common tablets, liquid injection preparations, freeze-dried powder injection and the like.
The existing sodium ferulate preparation has the following defects:
1. the common tablet has low bioavailability and large side effect on the digestive tract, needs to be taken three times a day and has poor compliance after long-term taking;
2. although the liquid injection preparation and the freeze-dried powder injection avoid the side effect of the digestive tract, the phenomenon of peak valley of the blood concentration still exists, and when the blood concentration is at the peak, the blood concentration can be higher than the minimum toxic concentration of the medicine in a short time, so adverse reactions and even poisoning are easily caused; at "trough" levels, the plasma concentration is likely to be below therapeutic levels and not effective.

The invention also discloses a preparation method of the sodium ferulate controlled release tablet, which comprises the following steps:
the method comprises the following steps: preparing raw materials: the weight portions are as follows: 12-15 parts of sodium ferulate, 7-12 parts of controlled release material and 73-81 parts of pharmaceutically acceptable auxiliary materials;
step two: mixing: uniformly mixing a sodium ferulate raw material medicine, 60-mesh-screened polyethylene oxide (PEON N-10) and sodium chloride, adding absolute ethyl alcohol to prepare a soft material, granulating by using a 18-mesh sieve, drying at 40 ℃, taking out, adding magnesium stearate, uniformly mixing to obtain medicine-containing layer granules, uniformly mixing 60-mesh-screened polyethylene oxide (PEO WSR303) and sodium chloride, adding absolute ethyl alcohol to prepare a soft material, granulating by using a 18-mesh sieve, drying at 40 ℃, taking out, adding magnesium stearate, uniformly mixing to obtain pushing layer granules, and pressing the medicine-containing layer and the pushing layer granules into a double-layer tablet core;
step three: coating: adding cellulose acetate into acetone, stirring to dissolve to obtain coating solution, placing the pressed double-layer tablet core into a coating pan, and coating;
step four: drying and curing: drying the coated product at 40 deg.C, and curing;
step five: punching: a small hole of 100-60 microns is punched in the center of the medicine-containing layer of the coated tablet by a laser-beam drilling machine.
Compared with the prior art, the invention has the beneficial effects that:
(1) the blood concentration is stable, the peak valley phenomenon is avoided or reduced, and the toxic and side effects are favorably reduced;
(2) the total dosage of the medicine is reduced, and the maximum medicine effect can be achieved by using the minimum dosage;
(3) the frequency of administration is reduced, and the administration compliance of a patient is improved;
(4) is favorable for reducing the adverse reaction of the medicine.
