Usually, the new
low-speed tablet press die can only be shipped before it is tested by the manufacturer's inspection department, and will be accompanied by documents that prove the quality. The imported die will even have detailed data for each die.
Now many purchasers of pharmaceutical companies like to buy some poor quality dies with low prices, which requires users to do some necessary testing before the formal use of the die, so as not to cause unnecessary losses. Similarly, some samples can be tested for the die used over a period of time to determine if the die is still in a qualified state.
In the choice of materials, materials should be chosen to prevent chemical reactions in the raw materials. The low-speed tablet press die is a part that is in direct contact with the material. It is related to the quality and safety of the tablet, so it needs to be made of corrosion-resistant materials. For special formula materials that are easily chemically reacted with materials to cause discoloration, a more stable material should be replaced before the test piece. In addition, the design of the die structure of the low-speed tablet press should be reasonable to prevent cross-contamination of the raw materials during the tableting process. The structural design should be humanized, free of dead angles, easy to clean, convenient for users to clean thoroughly after use, and ensure normal and pollution-free production of the products. .
The low-speed tablet press die is very precise. The users of the pharmaceutical factory should recommend a special die storage and storage system. There is a special storage room, and the room should be kept dry.
After the mold is used, it must be removed and cleaned on the tablet press. It should be placed in alcohol or clean olefin oil for cleaning. The attached material on the mold should be softened, then dried with cotton cloth and coated with anti-rust oil. Put it into a special protective box or put it on the rack in the die storage box. It should be marked with the size to facilitate the next use.
Do not mix unused dies with the same size with used dies.
Under normal circumstances, after the low-speed tablet press die is used, in order to ensure the smooth surface of the die, the pharmaceutical factory users can polish themselves and often check for rust, cracks, abrasion and other rust phenomena.
Nootropic Products
In China, nervous system drugs are also one of the drugs with the most rapid sales growth in recent years. In 2002, nervous system drugs occupied 5.9% of the entire pharmaceutical market share, and the total sales amount increased by 9.4%.
With the increasing trend of urbanization and aging, the elderly population in China has exceeded 120 million, and the incidence of geriatric diseases, especially mental diseases, is increasing year by year. With the increase of residents' income, the elderly's requirements for quality of life also increase. As a result, the demand for drugs to treat mental illnesses such as Alzheimer's has soared. In WHO drug classification, psychotropic drugs and nootropic drugs are grouped into one class. We briefly analyzed the development trend of this class of drugs through the clinical drug use data collected from more than 300 domestic key hospitals by Chinese Pharmaceutical Association.
The overall market size of this class of drugs is about 1.22 billion yuan, the consumption sum increased by 5.0% in 2002, but the sales quantity increased by 11.2%. The main reason why the consumption sum did not increase with the sales quantity is that several main varieties of this class of drugs, such as piracetam, cobalt bin amide and ginkgo biloba leaf, etc. In 2002, the price of selling units fell sharply due to bidding. Among these drugs, ginkgo biloba preparation occupies the largest market share, accounting for more than 1/3 of the market share, ganglioside ester and cobalt bin amide combined also occupy nearly 1/3 of the market share, piracetam and other "sitan" drugs occupy nearly 10% of the market share, the rest of the drugs occupy less than 5% of the market share. At present, more than 20 ginkgo leaf production enterprises, piracetam production enterprises more than 70, have entered the stage of price competition, profit repeatedly diluted.
In the first-line varieties, except ginkgo biloba leaves preparation maintained vigorous vitality, the growth of other varieties were weak, especially the traditional variety piracetam suffered from bidding
