Embodiment 1

[0048] Put 45 mg of commercially available Shexiang Baoxin Pills (Shanghai Hehuang Pharmaceutical Co., Ltd., batch number 150415) into a mortar and grind them into fine powder. The fineness of the powder of Shexiang Baoxin Pills is <120 mesh. Then add 30 mg of racemic polylactic acid (PLA) and mix, vortex at room temperature for 15 minutes at a rate of 1750 rpm to disperse the particles evenly, then add 110 mg of dimethyl sulfoxide, and extract by ultrasonic at 25°C and extraction power of 240W After 8 hours, the Shexiang Baoxin Pill sustained-release gel sample 1# was obtained. Shexiang Baoxin Pill Sustained-release Gel Sample 1# is a transparent semi-solid brown preparation. In the prepared Shexiang Baoxin pill sustained-release gel sample 1#, by weight percentage, the powder of Shexiang Baoxin pill was 24.3%, the content of racemic polylactic acid was 16.2%, and the content of dimethyl sulfoxide was 59.5%.

Embodiment 2

[0050] Put 45 mg of commercially available Shexiang Baoxin Pills (Shanghai Hehuang Pharmaceutical Co., Ltd., batch number 150415) into a mortar and grind them into fine powder. The fineness of the powder of Shexiang Baoxin Pills is <120 mesh. Then add 30 mg of racemic polylactic acid (PLA) and mix, vortex at room temperature at a rate of 1500-2000 rpm for 10-20 minutes to disperse the particles evenly, then add 102.8 mg of N-methylpyrrolidone, extract at 25 ° C, power Ultrasonic extraction at 240W for 8 hours to obtain Shexiang Baoxin Pill sustained-release gel sample 2#. Shexiang Baoxin Pill Sustained-release Gel Sample 2# is a transparent semi-solid brown preparation. In the prepared Shexiang Baoxin pill sustained-release gel sample 2#, by weight percentage, the powder of Shexiang Baoxin pill was 25.3%, the content of racemic polylactic acid was 16.9%, and the content of N-methylpyrrolidone was 57.8%.

Embodiment 3

[0052] Put 45 mg of commercially available Shexiang Baoxin Pills (Shanghai Hehuang Pharmaceutical Co., Ltd., batch number 150415) into a mortar and grind them into fine powder. The fineness of the powder of Shexiang Baoxin Pills is <120 mesh. Then add 30 mg of racemic polylactic acid (PLA) and mix, vortex at room temperature at a rate of 1500-2000 rpm for 10-20 minutes to disperse the particles evenly, then add 55 mg of dimethyl sulfoxide and 50 mg of water, at 25 ° C, Ultrasonic extraction at 240W for 8 hours to obtain Shexiang Baoxin Pill sustained-release gel sample 3#. Shexiang Baoxin Pill Sustained Release Gel Sample 3# is a transparent semi-solid brown preparation. In the prepared Shexiang Baoxin pill sustained-release gel sample 3#, by weight percentage, Shexiang Baoxin pill powder is 25.0%, racemic polylactic acid is 16.7%, dimethyl sulfoxide and water are 58.3%.
