Abstract

The invention discloses a compound lidocaine emulsifiable paste and a preparation method thereof. Each 10kg of the compound lidocaine emulsifiable paste comprises the following components according to the weight: 50-1000g of base lidocaine, 50-1000g of base prilocainum, 10-500g of polyoxyethylene hydrogenated castor oil, 10-300g of Carbomer, 40-200g of sodium hydroxide and the balance of pure water. The invention increases clinical use security through releasing lidocaine and prilocainum in base modes to the subcutaneous layer with the depth of 5mm without containing a penetrating agent or a surface active agent component, which is particularly suitable for children patients and patients for face beauty. Through improvement on production process steps, the invention enables the production operation to become easy and feasible, is easy to control the product quality and increases the product stability. The whole production cycle is only half day, and the production efficiency is improved by more than 3 times, thereby the raw materials are saved and the production cost is reduced.

Description

technical field [0001] The invention relates to a medical cream and a preparation method thereof. Background technique [0002] The traditional compound lidocaine cream needs to add penetrants, such as: azone and surfactants such as: Tween 80, etc. Its purpose is to destroy the epidermal tissue of the skin to increase the subcutaneous penetration effect. But it is harmful to the skin like this, and the purpose of safe medication cannot be achieved. Tween 80 has a strong effect of breaking cell membranes and causing irritation. The medical community has confirmed that Tween 80 can cause allergic reactions, including shock, dyspnea, hypotension, angioedema, and urticaria and other allergic-like reaction symptoms. These adverse reactions can be very serious in human clinical trials, with deaths reported. Therefore, there are strict restrictions on the use of Tween 80. It is a potentially unsafe auxiliary material, and improper use will have a great impact on human health. T...
