Description
Technical field
The present invention relates to field of pharmaceutical chemistry technology, especially relate to a kind of prepare long effect duration technetium [
99mtc] method of methylene diphosphonate injection medicine.
Background technology
Technetium [
99mtc] methylene diphosphonate injection is the ideal skeletal imaging agent of generally acknowledging at present, be by high technetium [
99mtc] sour sodium and injection methylenediphsphonate and stannous chloride formulated by certain proportioning.Technetium [
99mtc] methylene diphosphonate injection by chemisorbed be incorporated in the inorganic constituents of skeleton hydroxylapatite crystal surface, immature collagen in this dermoskeleton, also to technetium [
99mtc] methylene diphosphonate injection has higher affinity.Affect the dense poly-technetium of skeleton [
99mtc] principal element of methylene diphosphonate injection be skeleton blood for and the synthesis speed of new bone.
In addition technetium [
99mtc] methylene two sees the myocardial cell or the soft tissue of calcification that hydrochlorate injection can also be positioned to block, and enters muscle, cartilage, blood vessel and internal organs.But technetium [
99mtc] effect duration of methylene diphosphonate injection is only 6 hours, stops over slightly in transit, by expired, causes waste.
Chinese patent CN103203032A disclose a kind of technetium [
99tc] methylene two sees hydrochlorate preparation and preparation method thereof.Technetium in this patent [
99tc] methylene diphosphonate preparation is lyophilized injectable powder, contains in unit formulation: high technetium [
99tc] sour sodium 0.05 μ g ~ 1 μ g (with
99tc counts), methylenediphosphonate 5mg ~ 100mg, stannous chloride 0.5mg ~ 5mg.This patent further disclose technetium [
99tc] preparation method of methylene diphosphonate lyophilized injectable powder.In this patent, technetium [
99tc] methylene diphosphonate lyophilized injectable powder effectively improves
99the complexation rate of Tc and methylenediphosphonate, improve technetium [
99tc] stability of methylene diphosphonate preparation and effectiveness, avoid clinical before the risk of preparation microbiological contamination, reduce production cost.
Summary of the invention
Object of the present invention be exactly provide to overcome defect that above-mentioned prior art exists a kind of prepare long effect duration technetium [
99mtc] methylene two sees the method for hydrochlorate injection medicine, and the method can make expiration date of drug long, and transportation is not decomposed, and imaging results is better.
Object of the present invention can be achieved through the following technical solutions:
A kind of prepare long effect duration technetium [
99mtc] method of methylene diphosphonate injection medicine, obtained technetium [
99mtc] after methylene diphosphonate injection, to technetium [
99mtc] add vitamin C injection in methylene diphosphonate injection.
The method specifically comprises the following steps:
(1) vitamin C injection is diluted to 0.005g/L ~ 0.05g/L;
(2) extract high technetium [
99mtc] sour sodium injection, and dilute;
(3) injection stannous chloride methylene diphosphate dried frozen aquatic products is placed to room temperature from refrigerator taking-up;
(4) by high technetium [
99mtc] sour sodium injection is disposable is expelled in stannous chloride methylene diphosphate dried frozen aquatic products, concussion, fully dissolves, and leaves standstill, obtain technetium [
99mtc] methylene diphosphonate injection;
(5) by the vitamin C injection diluted with disposable sterilized use syringe extract inject prepare technetium [
99mtc] in methylene diphosphonate injection, shake up.
Described high technetium [
99mtc] activity of sour sodium injection is 10 ~ 200mCi.
In step (4), high technetium [
99mtc] proportionate relationship of sour sodium injection and stannous chloride methylene diphosphate is 4ml: 5mg.
In step (5), the addition of vitamin C injection and high technetium [
99mtc] volume ratio of sour sodium injection is 0.1: 4.
Compared with prior art, the present invention has the following advantages and beneficial effect:
(1) technetium [
99mtc] effect duration of methylene diphosphonate injection is 6 hours, substantially can keep stable, afterwards along with the prolongation of time within 6 hours, decompose aggravation, because vitamin C has reproducibility, inhibit after adding vitamin c solution high price technetium generation, make technetium [
99mtc] methylene diphosphonate injection do not decompose, and quality is more stable, and is convenient to transport.
(2) and after adding vitamin C, technetium [
99mtc] methylene diphosphonate injection do not decompose, and do not have a large amount of sodium pertechnetates after injection free out, assemble at thyroid position.When carrying out bone scanning, thyroid can not develop, make technetium [
99mtc] methylene diphosphonate injection has better imaging results.
