Abstract

The invention provides a freeze-dried sublingual tablet containing hydrophobic active substances, which is prepared from active substances and auxiliary materials and is characterized in that the auxiliary materials include medicine carriers and assistants, wherein the medicine carriers are natural polysaccharide high molecular materials which exist in water in nano sizes and have hydrophobic regions, and the active substances are hydrophobic active substances. The freeze-dried sublingual tablet containing hydrophobic active substances, provided by the invention, can effectively and quickly carry and supplement hydrophobic medicines, and the medicines can be carried uniformly, thereby being favorable for playing roles of the medicines; and meanwhile, the hydrophobic medicines are prepared into the freeze-dried sublingual tablets, and then the medicines can quickly pass through the sublingual region to enter the blood for circulation, thereby playing roles.

Description

technical field [0001] The invention belongs to the field of medicine, and relates to a freeze-dried sublingual tablet containing hydrophobic active substances and a preparation method thereof. Background technique [0002] In pharmaceuticals, oral preparations account for a high proportion, among which solid preparations are the most important form of oral preparations. However, the solid preparations currently on the market are mainly aimed at hydrophilic drug molecules, and cannot treat some hydrophobic drugs, vitamins, trace amounts, etc. elements, such as vitamin D3, vitamin B3 and other hydrophobic vitamins; on the other hand, taking these hydrophobic vitamins, drugs or trace elements directly will cause some adverse reactions, such as vitamin B3 and iron supplements will make people The stomach produces severe adverse reactions, therefore, these drugs either cannot be directly made into oral preparations, or the prepared oral preparations have strong side effects. Ho...
