Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a paracetamol vitamin C effervescent tablet and a preparation process thereof. Background technique [0002] Acetaminophen, usually a white crystalline powder, is obtained by reducing sodium p-nitrophenolate to p-aminophenol and then acylation. It is the most commonly used non-steroidal anti-inflammatory antipyretic and analgesic drug. Its antipyretic effect is similar to that of aspirin. It is the best variety among acetanilide drugs, especially suitable for patients who cannot use carboxylic acid drugs. In addition, it is used for joint pain, neuralgia, migraine, cancer pain and pain relief after surgery. [0003] Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin. It plays an important regulatory role in redox metabolism, lack of it will cause scurvy; in addition, it can promote the synthesis of collagen, which is beneficial ...
