Embodiment 1

[0089] Preparation of gossypol acid thermosensitive gel (liquid preparation I)

[0090] 18 kilograms of Poloxamer127 (purchased from Shanghai Changwei Pharmaceutical Excipient Technology Co., Ltd.) and 0.65 kilograms of F68 (purchased from Shanghai Changwei Pharmaceutical Excipient Technology Co., Ltd.) were placed in the stirrer, and 60 liters of 0.4M acetate buffer was added. Stir well at 25°C and stir at a speed of 100-300rpm to dissolve completely. The process takes about 3-4 hours. After completion, add 0.8 kg of pure gossypol, 10 liters of glycerin, 0.5 liters of polydimethylsiloxane and 0.1 liters of Benzoic acid (purchased from Shanghai Changwei Pharmaceutical Excipient Technology Co., Ltd.), stirred for another 1-2 hours, left to stand overnight, and centrifuged for 15 minutes to remove air bubbles. Finally, a total of 100 liters of this product was prepared with 0.4M acetic acid buffer. The pH and viscosity of the gel were measured (room temperature 23-25°C).

[0093] Preparation of 8-benzoyl-1,4-benzoquinone acidic thermosensitive gel (liquid preparation II)

[0094] 19.2 kilograms of Poloxamer127 (purchased from Shanghai Changwei Pharmaceutical Excipient Technology Co., Ltd.) and 0.5 kilograms of F68 (purchased from Shanghai Changwei Pharmaceutical Excipient Technology Co., Ltd.) were placed in the stirrer, and 60 liters of 0.2M acetate buffer was added. Stir well at 25°C and stir at 100-300rpm to dissolve completely. The process takes about 3-4 hours. After completion, add 0.2 kg of 8-benzoyl-1,4-benzoquinone, 10 liters of glycerin, and 0.5 liters of polydimethyl Siloxane and 0.1 liter of benzoic acid (purchased from Shanghai Changwei Pharmaceutical Excipient Technology Co., Ltd.), were stirred for 1-2 hours, left standing overnight, and centrifuged for 15 minutes to remove air bubbles. Finally, a total of 100 liters of this product was prepared with 0.2M acetic acid buffer. Measure the pH and viscosity of the gel.

Abstract

The invention discloses liquid preparation with gossypol or other analogs. The liquid preparation contains (a) 0.01to 10 weight percent of gossypol or other analogs; (b)12 to 20 weight percent of polyoxypropylene polymer, alginic acid or chitosan; (c) 0.5 to 10 weight percent of poly (dimethylsiloxane), poly (dimethylsiloxalkanol) or dimethylsiloxalkyl ether polymer; and (d) 1.0 to 2.5 weight percent of acidic buffering agent. The invention also discloses a preparation method and usage of the liquid preparation.

Description

technical field [0001] The invention relates to a pharmaceutical preparation, in particular to a liquid preparation of gossypol or its analogues, a preparation method and application thereof. Background technique [0002] Gossypol is a yellow polyphenolic toxic compound contained in the roots, stems and seeds of the Malvaceae plant cotton. The chemical structure of gossypol is 8,8'-dialdehyde-1,1,6,6'7,7'-hexahydroxy-5,5'-diisopropyl-3,3'-dimethyl- 2,2'-binaphthalene, as shown in formula 1: [0003] [0004] Formula 1 [0005] Gossypol has a sperm-inhibiting effect, but gossypol has effects on certain functions of the human or animal body. For example, gossypol may induce primary hypothyroidism; it can reduce serum motilin levels in mice and inhibit weight gain; it can reduce serum potassium and increase urinary potassium in patients with hypokalemia; some people who take gossypol After taking 0.5-4.5 years, there is still no sperm in the semen or the sperm in the sem...
