Embodiment 1

[0028] Because the water solubility of temsirolimus ester compound is very poor, solubilizer is needed to solubilize, the contriver is to commonly used cosolvent polysorbate 80 in the injection, polyethylene glycol stearate 15 (Solutol-HS15), Tocopheryl polyethylene glycol succinate (TPGS), sodium deoxycholate, etc. were screened, and the prescription was designed as follows:

[0029] Co-solvent screening of temsirolimus ester lyophilized preparation

[0030]

[0031] The above prescription was studied on the influencing factors at 40°C, and the results are shown in the table below:

[0032]

[0033] The experimental results show that in four typical co-solvents polysorbate 80, polyethylene glycol stearate 15 (Solutol-HS15), tocopherol polyethylene glycol succinate (TPGS), sodium deoxycholate , the stability of the pharmaceutical composition containing the temsirolimus ester compound of polyethylene glycol stearate 15 (Solutol-HS15) is the best, so in follow-up research, ...

Abstract

The invention relates to a medicinal composition containing temsirolimus and a preparation method of the medicinal composition. Polyethylene glycol stearate 15 as latent solvent is added in a formula, so that the problem of settlement generated by clinically using physiological saline to dilute a temsirolimus freeze-dried powder injection is effectively solved, further the content of an isomer of the temsirolimus and the content of oxidative degradation impurities are reduced and the stability and the safety of the medicament are improved. The freeze-dried medicinal composition disclosed by the invention is simple in preparation process and low in production cost and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to a pharmaceutical composition containing temsirolimus ester compound and a preparation method thereof. Background technique [0002] Sirolimus ester compound (English name, Temsirolimus) is 42-bis-hydroxymethyl propionate of rapamycin, and its structural formula is as follows: [0003] [0004] This compound was first disclosed in US Patent No. 5,362,718A, and it exhibits inhibition of cell growth and reproduction in in vivo and in vitro models, rather than cytotoxicity, and it can also delay the development time of tumors or the recurrence time of tumors. The mechanism of action is considered to be similar to that of sirolimus, mainly by binding to the cytoplasmic protein FKBP and forming a complex, inhibiting the enzyme mTOR (mammalian target of rapamycin, also known as FKBP12-sirolimus-related protein [FRAP]). Inhibition of mTOR kinase activity leads ...
