Problems solved by technology

[0003] 5-Fluorouracil is poorly soluble, slightly soluble in water, slightly soluble in ethanol, and almost insoluble in chloroform; it dissolves in dilute hydrochloric acid or sodium hydroxide solution, so it is difficult to formulate it into a form suitable for administration
However, this method of administration also has many disadvantages, such as bone marrow suppression, short half-life in vivo, nausea and vomiting and other adverse gastrointestinal reactions.
In addition, the clinical intravenous injection time is prolonged, which brings inconvenience and pain to the patient

Embodiment 1

[0115] Example 1 Synthesis of 5-fluorouracil drug eutectic with nicotinamide as precursor by liquid phase assisted grinding method

[0116] 1. Synthesis of 5-fluorouracil drug co-crystal with nicotinamide as precursor by liquid phase assisted grinding method:

[0117] Accurately weigh 3mmol (390.0mg) of 5-fluorouracil and 1mmol (122.0mg) of nicotinamide with an analytical balance, put them into an agate mortar with a diameter of 8-15cm, carefully grind the reactants evenly and finely grind the reactants to a powder of 100-300 mesh. Use a micropipette to transfer 20 μL of deionized water into the above powder, and grind it uniformly for 10 minutes quickly to obtain a 5-fluorouracil drug cocrystal with nicotinamide as a precursor.

[0118] The 5-fluorouracil pharmaceutical co-crystal prepared above was subjected to structural characterization and performance testing through the above-mentioned equipment:

[0119] Such as figure 1 As shown, three 5-fluorouracil molecules, one n...

Abstract

The invention discloses a medicine preparation containing 5-fluorouracil drug eutectic with nicotinamide as a precursor and a preparation method of the medicine preparation.5-fluorouracil raw material medicine is selected as medicine API, nicotinamide serves as the medicine precursor, a liquid-phase assisted grinding method is adopted, the high-purity 5-fluorouracil drug eutectic is obtained, and the effect that the medicine can be more stable can be achieved; in addition, the invention further provides the medicine preparation containing the 5-fluorouracil drug eutectic, the medicine preparation comprises tablets, slow-release tablets, microspheres, micro-capsules, suppository, emulsion, a film agent and an injection agent so that stability and the curative effect of the 5-fluorouracil drug eutectic with the nicotinamide as the precursor can be better improved, different medicine application modes are utilized, and possibility of fully playing the treatment function of medicine and lowering or avoiding adverse reactions is provided.Auxiliaries applied to the preparation method of the preparation are easy to buy in the market and low in price, therefore cost is quite low, and the medicine application burden of patients can be remarkably lowered.

Description

technical field [0001] The invention relates to a pharmaceutical preparation and a preparation method thereof, in particular to a pharmaceutical preparation of 5-fluorouracil drug co-crystal containing nicotinamide as a precursor and a preparation method thereof, and belongs to the technical field of preparation of pharmaceutical preparations. Background technique [0002] 5-Fluorouracil, synthesized by Heidelberger in 1957, has lethality to proliferating cells. It is a classic antineoplastic drug collected in Pharmacopoeia. 5-Fluorouracil is the first anti-metabolite drug synthesized according to a certain assumption and is currently the most widely used anti-pyrimidine drug in clinical practice. In recent decades, 5-fluorouracil has always played an important role in medical oncology treatment. It is effective in the treatment of a variety of tumors such as digestive tract cancer, breast cancer, ovarian cancer, choriocarcinoma, cervical cancer, bladder cancer, liver cancer...
