What is pharmaceutical preparation engineering design?

The starting point of new drug research and development is an important link that determines the safety, effectiveness, controllability, stability and compliance of drugs, and it is also the engineering design of pharmaceutical preparations.

The so-called pharmaceutical preparation, in a narrow sense, is a specific finished drug prepared according to a certain dosage form, such as amoxicillin capsules. In a broad sense, it is pharmaceutical pharmacy and a discipline. Pharmaceutical preparations solve the problem of drug usage and dosage. Pharmaceutical preparations play a very important role in the human body.

Drugs refer to substances used to prevent, treat and diagnose human diseases, purposefully regulate human physiological functions, and specify indications, usage and dosage, including Chinese herbal medicines, Chinese herbal pieces, Chinese patent medicines, chemical raw materials and their preparations, antibiotics, biochemical drugs, radioactive drugs, serum vaccines, blood products and diagnostic drugs.

Pharmaceutical preparations are actually around us. If we catch a cold, we will take some cold medicine. Some people eat "Contek" in capsules, while others eat "Gankang" in tablets. In fact, "capsules" and "tablets" are both pharmaceutical preparations, and the functions of pharmaceutical preparations are generally divided into two categories.

Avoid making patients suffer from pain. Pharmaceutical preparations can make drugs play their roles and effects as "drugs". Insulin is a kind of protein, which will decompose and fail after being eaten by human body. However, if insulin is made into injection, it will play a therapeutic role for diabetic patients.

Stability:

In order to know whether the prescription is appropriate, whether the manufacturing process is reasonable, whether the preparation is stable or not, or for the service life of the drug, the stability test can be carried out by applying the principle of chemical kinetics. In the experiment, except the factors to be investigated, other factors that can affect the accuracy of the experiment should remain unchanged, otherwise it is difficult to draw a definite conclusion when all factors are mixed together.

Before the stability test of pharmaceutical preparations, it is possible to distinguish the contents of reactants or decomposition products, but the method of determining drugs is usually chosen, because decomposition products can distinguish the contents of reactants or decomposition products, but the method of determining drugs is usually chosen, because decomposition products are often complicated, and sometimes decomposition products may decompose again immediately.
