There are the following types of insulins according to the different duration of action: 1) rapid-acting insulins, i.e. ultra-short-acting insulins, which are generally common, such as menthol insulin injection, lysine insulin injection and glulam insulin. 2) short-acting insulins, i.e. regular insulins, which are clinically available, such as Novolin and Utrolin. 3) medium-acting insulins, i.e. low arginine zinc human insulin injection. 4) long-acting insulin analogues, including detergent insulin, glargine, etc. 5) premixed insulin analogues, such as menthol insulin 30, etc., and premixed human insulins, which are composed of short-acting insulin and medium-acting insulin. 5, the more commonly used premixed insulin analogues, such as menthol insulin 30, etc., and premixed human insulin, which is made of short-acting insulin and intermediate-acting insulin mixed in different proportions, has the common efficacy of two insulins, and has the efficacy of controlling mealtime blood sugar and basal blood sugar at the same time, such as ordinary insulin and arginine zinc insulin synthesis of Novolin 30R, 50R, etc.
