Embodiment 1

[0021] ① Take 300mg of poly(lactic-co-glycolic acid) (PLGA) and add it into 1ml of dichloromethane to prepare a solution;

[0022] ② Add 50 mg of arubicin to the solution prepared in ①, and mix well by ultrasonic;

[0023] ③Use a syringe to slowly inject the solution in ② into the cottonseed oil containing 0.05% egg yolk oil, stir at 1000r / min for 20min, then reduce the speed to 200r / min and continue stirring for 4h;

[0024] ④Add 20ml petroleum ether to step ③, centrifuge at 8000r / min for 5min after 30min;

[0025] ⑤ Collect the microspheres, wash with petroleum ether and evaporate to dryness.

Embodiment 2

[0027] ① Take 200mg PLGA and add it to 1ml tetrahydrofuran solution to prepare a solution;

[0028] ② Add 50 mg of mitoxantrone to 0.2 ml of glycerin, mix well and add to the solution prepared in ①, stir with a homogenizer for 1 min to obtain colostrum;

[0029] ③Add it to 12ml of 2% polyvinyl alcohol (PVA) solution, stir at 1000r / min for 5min, then add 120ml of 0.5%PVA solution to obtain double emulsion;

[0030] ④ Reduce the rotational speed to 200r / min and continue stirring for 4h, then centrifuge at 8000r / min for 5min;

Abstract

The invention discloses an application of anthracene nucleus antibiotic and its pharmaceutical salt for treating neovascular glaucoma. The invention found that the anthracene nucleus antibiotic and its pharmaceutical salt have good effect on treatment of r neovascular glaucoma, and especially the anthracene nucleus antibiotics can be prepared to prolonged action preparations such as a nano preparation, a microballoon preparation, liposome and hydrogel, the toxicity of anthracene nucleus antibiotic is reduced, and the anthracene nucleus antibiotic enables ophthalmic administration, administration dosage is simultaneously enlarged, the duration time of drug effect is long, the medicament curative effect is stronger than that of the common preparations of the anthracene nucleus antibiotic, when the ophthalmic administration is carried out, the anthracene nucleus antibiotic has good treatment effect for treating retinal vein occlusion, and the blank that no medicine is good for treating neovascular glaucoma can be filled.

Description

technical field [0001] The present invention relates to a medicine for treating neovascular glaucoma, in particular to the new application of a series of traditional antitumor antibiotics anthracyclines and pharmaceutically acceptable salts thereof in the preparation of medicines for treating neovascular glaucoma, in particular, the anthracene Cyclic antibiotics and their pharmaceutically acceptable salts are prepared into long-acting preparations such as nanometer preparations, microsphere preparations, liposomes and hydrogels. Background technique [0002] Neovascular glaucoma is a secondary glaucoma disease, mainly manifested in a large number of new blood vessels on the iris of the patient's eyes, showing the symptoms of glaucoma. There are many causes of neovascular glaucoma, but the most important causes of neovascular glaucoma are retinal vein occlusion and diabetic retinopathy. These two eye diseases can be secondary to neovascular glaucoma. The neovascular glaucoma ...
