Description

technical field

[0001] The present invention relates to a suitability testing method for a microneedle material prepared by a stretching process and a method for preparing a microneedle comprising the same. Background technique

[0002] Many drugs and physiologically active substances have been developed for the treatment of diseases, but in the process of delivering drugs and physiologically active substances into the body, biological barriers (biological barriers, such as skin, oral mucosa, and cerebrovascular barrier, etc.) pass through problems And the efficiency of drug delivery still needs to be improved.

[0003] Drugs and physiologically active substances are usually administered orally in the form of tablets or capsules, but due to reasons such as being digested or absorbed in the gastrointestinal tract or being lost by hepatic mechanisms, many drugs cannot be effectively delivered by the above-mentioned methods of administration alone . Moreover, some drugs do no...
