What is the abbreviation of the relief on the pill? When taking medicine, we often find Chinese, English or Arabic numerals printed on the tablets. Sometimes, patients are often confused by the same drug produced by different pharmaceutical factories, some printed and some not printed. So, what exactly does the initials embossed on the pills mean? The main purpose of printing words on tablets is to make people easily identify drugs when using them, and to ensure the safety and effectiveness of drugs. Besides, there is no difference in treatment or quality. 1988 the Ministry of health has issued unified characters for abbreviations of 27 kinds of drugs, but in the production process, the implementation of characters is different, some are printed and some are not printed. Especially in recent years, with the increase of Sino-foreign joint venture pharmaceutical factories, the number of medicines printed with letters has gradually increased, because most of them have adopted the practice of foreign pharmaceutical production, and printed the drug name and company name abbreviation on tablets, which is not only convenient for identification, but also plays a role in publicity. This paper introduces several common representations: 1. Stamping Chinese drug names. Such as diazepam, aminophylline and diclofenac. 2. Print Latin abbreviations of drug names. Such as: Vc (vitamin C), APC (compound aspirin) and so on. 3. Stamp the brand name and company name. For example, Lin Shujiao, an anti-inflammatory and analgesic drug, has printed on its tablets Clinoril (the trade name of the drug is Chinoli) and M.S.D (the company name is Merck, USA). 4. Stamp the drug name, company name abbreviation and specifications. For example, the anti-allergic drug Cistamine is printed with Ast (abbreviation: Astemizoli) and 10 (indicating the specification as 10 mg).
