The role of physical chemistry in pharmacy, what are the applications of chemistry in pharmacy

If you study pharmacy, you will definitely study physical chemistry, instrumental analysis, and in the senior year, you will also study medicinal chemistry.

Drug design, many of these disciplines involve thermodynamics.

Optics, Quantum Physics.

Therefore, learning physics, especially basic physics knowledge, helps to understand the basic principles in the above disciplines, such as the first and second laws of heat in physics, which are the knowledge points of the first few chapters of physics and chemistry, and instrumental analysis such as infrared spectroscopy.

The basic principles involve the path calculation of optics and the knowledge of quantum optics, so physics is mainly used to explain the basic principles of some pharmaceutical disciplines in pharmacy, because chemistry and biology are essentially physics.

The quality of the physical chemistry foundation will definitely affect pharmacy, but don't worry too much, many Chinese medicine universities.

The major of Chinese Materia Medica has a recruitment of liberal arts students.

There is a bottom.

Don't laugh at it, let's be serious, the chemistry of Chinese medicine in college is not very related to high school chemistry, that is, there is some correlation between inorganic and organic basic theories, and the teacher will help you review it somewhat, and it's okay if you don't review it. Generally speaking, the chemistry of Chinese medicine is not very difficult compared to science students, and if it is difficult, physical chemistry is more difficult. In addition to the materialization of the more failed subjects, the other failed rates are very low are not easy to learn, a little bit of work is still okay to take the test seventy or eighty.

Although chemistry is not difficult, it is still more trivial for other disciplines of chemistry, and you need to summarize it frequently, which requires your attention.

Pharmaceutical: preparation and stability of colloids, emulsions, and suspensions; The application of co-solvents ......Surface phenomena and the application of surfactants. Extract 、......Infiltration, diffusion and mass transfer Concentration 、......The phase change process is ...... dryingSpray drying ......Superficial phenomena.

Analysis: Extraction: Partition Coefficient; chromatographic principles and efficiency formulas; Wait a minute.

For drugs, especially liquid drugs, there are many insoluble, so the insoluble ingredients can be made into micelles with solubilizers to solve the problem. There is also a solution to the dissolution of chemical drugs, and it also has a positive significance of slowing down trouble.

The main application is drug synthesis, the most classic is aspirin.

The world's most widely used antipyretic, analgesic and anti-inflammatory drug, salicylic acid.

and acetic anhydride to synthesize aspirin.

Pharmacy is a derivative of chemistry, and chemistry is the quiet foundation of pharmacy. Pharmacy is the derivation of chemical materialism, chemistry is the basis of pharmacy, without the basis of chemistry can not develop pharmacy, without pharmacy can not be pharmaceutical, can not treat patients, so we must learn chemistry well, develop more and better drugs.

The understanding of pharmacology is as follows:

Pharmacology concept: Pharmacology: It is one of the disciplines that study drugs, mainly studying the laws and mechanisms of interaction between drugs and the body (including pathogens).

Drugs: Substances that can affect the physiological, biochemical and pathological processes of the body to prevent or diagnose diseases.

Pharmacology studies include:

1. Pharmacodynamics: referred to as pharmacodynamics. To study the effects of drugs on the body, including the effects and effects of drugs, mechanisms of action and clinical applications.

2. Pharmacokinetics: referred to as pharmacokinetics. The study of the changes and laws of drugs under the action of the body, including the absorption, distribution, metabolism and excretion of drugs in the body, especially the changes in blood drug concentration over time, and the factors affecting the efficacy of drugs.

Nature:

Pharmacology is one of the disciplines that study drugs, and it is a basic medical discipline that provides basic theories for the prevention and treatment of diseases with rational clinical drug use. Pharmacology is the study of the laws and principles of the interaction between drugs and the body, including pathogens.

Drugs refer to substances used to prevent and diagnose diseases, and theoretically speaking, all chemical substances that can affect the physiological functions of body organs and the metabolic activities of (or clump) cells belong to the category of drugs and drugs, including contraceptives and health care pills.

On the one hand, pharmacology studies how the function of body cells changes under the influence of drugs, and on the other hand, it studies the process of the drug itself in the body, that is, how the body processes the drug, the former is called pharmacodynamics, referred to as pharmacodynamics; The latter is called pharmacokinetics, or pharmacokinetics for short.

Medicinal chemistry: 1. Medicinal chemistry is an interdisciplinary discipline in which chemistry and life sciences penetrate each other, and its main task is to create new drugs and discover leads with further development prospects.

2. Medicinal chemistry is a classical science with a long history, which has a solid foundation for development, accumulated rich content, and made important contributions to human health.

3. The research on the skin of the line includes drugs and related substances and general physiologically active substances, and the main research object is drugs.

4. The research content involves the discovery, modification and optimization of lead compounds, revealing the mechanism of action of drugs and physiologically active substances at the molecular level, and studying the metabolic process of drugs and physiologically active substances in vivo.

1) Chemistry is the foundation of pharmacy, study and study pharmacy. It all started with chemistry. Discover and develop drugs using chemical concepts and methods, and then design and create new drugs from a chemical perspective.

Because high-end drug research focuses on discussing the principles and laws of action of drugs at the molecular level, and finding ways and methods for drug analysis and design. (2) The research content of pharmacy includes both chemistry and life science, and (3) inorganic chemistry and drugs are interrelated. At present, a large number of preparations based on inorganic substances have also appeared, and pharmaceutical inorganic chemistry has been a very active aspect in the past ten years.

The human body contains more than 20 kinds of elements, and these life elements perform their own duties in the living body, maintain the normal activities of the living body, and promote the development of the living body. Metals and their complexes occupy an extremely important hail honorable position in living organisms and medicines. Bioinorganic chemistry is of great significance for the elaboration of the pharmacology and mechanism of action of drug molecules, the improvement of drugs and the design of new drugs.
