Several terpene glycosides (e.g., mogroside V, paenoiflorin, geniposide, rubusoside, rebaudioside A, steviol mono-side and stevioside) were discovered to enhance the solubility of a number of pharmaceutically and medicinally important compounds, including but not limited to, paclitaxel, camptothecin, curcumin, tanshinone HA, capsaicin, cyclosporine, erythromycin, nystatin, itraconazole, celecoxib, clofazimine, digoxin, oleandrin, nifedipine, and amiodarone. The use of the diterpene glycoside rubusoside and monoterpene glycoside paenoiflorin increased solubility in all tested compounds. The terpene glycosides are a naturally occurring class of water solubility-enhancing compounds that are non-toxic and that will be useful as new complexing agents or excipients in the pharmaceutical, agricultural (e.g., solubilizing pesticides), cosmetic and food industries.

The invention relates to an application of an HMGCoA reductase inhibitor in preparation of a medicine used for treating xerophthalmia and belongs to the field of medicines. The inventor finds that a frequently-used lipid regulation medicine, the HMGCoA reductase inhibitor, can obviously prolong SIT time and BUT time and obviously reduce an FLS score when being used for treating the xerophthalmia, and the HMGCoA reductase inhibitor is better than ciclosporin or artificial tears in the aspect of improving the indexes, wherein simvastatin and lovastatin have the best treatment effect. The HMGCoA reductase inhibitor also can be prepared into oral preparation used for treatment or adjuvant therapy of the xerophthalmia.

The invention relates to the technical field of medicines, and in particular relates to a medicinal composition as well as a preparation and application thereof. The medicinal composition comprises a component a and a component b; the component a is rebamipide, pharmaceutically acceptable salt or isomeride thereof; and the component b is ciclosporin A, pharmaceutically acceptable salt or isomeride thereof. Experiments prove that a synergistic effect can be achieved when the rebamipide and the ciclosporin A are used together. The composition significantly improves the effects of promoting lacrimal secretion and eliminating inflammation compared with the effects achieved when the rebamipide and the ciclosporin A are used separately (P<0.05). Therefore, when the rebamipide and the ciclosporin A are compounded to prepare the medicament for treating xerophthalmia, the treatment effect can be improved.
