The science of preparing raw materials into pharmaceutical preparations

Substances that can be used to treat, prevent or diagnose human and animal diseases and affect the physiological functions of the body. The most basic characteristic of a drug is its activity in preventing and treating diseases, so it is also called an active substance (API) in the upstream stage of drug development. According to the source, drugs can be divided into three major categories: traditional Chinese medicine and natural medicine, chemical medicine and biotechnology medicine

No matter what kind of drugs they are, they cannot be directly applied to patients. Before they can be used clinically, they must be made into a form suitable for medical prevention applications and suitable for a certain route of administration. This form is called a pharmaceutical dosage form. , referred to as dosage form

The abbreviation of preparation refers to the specific drug type after the dosage form is determined.

Drug preparations are prepared through certain prescriptions and processes, and are commodities available for clinical use.

Can change the speed of drug action

Can reduce or eliminate the toxic and side effects of raw materials

Can improve drug stability

Can improve drug bioavailability and efficacy

Can change the properties of drugs

It is the study of the basic theory of industrialized production of preparations, the knowledge of process technology, production equipment and quality management.

The science of studying the absorption, distribution, metabolism and excretion processes of drugs and their preparations in the body, and elucidating the interrelationships between dosage form factors, biological factors of the body and drug effects.
