All of us have times when we are not feeling well so whenever we are not feeling well, in a fair amount of time, we think about taking medicine, medicine for us to relieve the pain and restore our health has become part of the public cognition. So why are drugs so amazing, and what's going on here? We often see all kinds of signs on the box or in the instructions and what about that? So let's take a look today. First of all, let's get to know what drugs are. Please look at them.
So we know what a drug is, we know that a drug has this therapeutic effect, and on the other hand, if it's a little bit insensitive it's a poison, and a poison is, right
Okay so now that we know these two basic concepts why does the drug work magically by what? So the next two theoretic pharmacokinetics and pharmacodynamics, the former basically explains the spatial distribution of a drug in the body at a given time, and as you can see, for example, there are models of when we take a drug. It's going to happen over time.
For example, a drug that we eat is absorbed in the small intestine, absorbed and then metabolized in the liver, and only a small part of it ends up in the bloodstream and then acts on our target organs. Pharmacokinetics also provide a theoretical basis for how we make drugs and how we take them and how we take them.
Then we have pharmacodynamics, and pharmacodynamics is the study of how a drug acts in the body after it's been distributed into the bloodstream, combined with the dose study of pharmacokinetics. To provide us with a comprehensive evaluation of the drug. Provide a basis for taking and making drugs. For example, we use this data a lot, so we know why does the drug give us the benefit of the doubt?
So how does the drug work? Actually drugs are actually certain chemicals, and our body is a large chemical plant, when the fully-automated factory we have certain production inside can't solve the problem of supply, the additional factors, drug as a foreign to us by artificial joined we need material, to ensure the safe production of the fully-automated factory we have.
The chemicals in the drugs seep into our body's biochemistry. Or something that interferes with the production of our chemical plants, like when someone has diabetes, the body knows it's not doing enough insulin. So we take insulin so that the body has enough insulin to maintain normal blood sugar. Another example is when there is a bacterial infection in the body, we use antibiotics. Antibiotics grow in the body by infecting the pathogen to remove the infection and ensure the health of the body. For example, we now see that antibiotics, through their functional groups, can fight infections by destroying bacterial cell walls, interfering with DNA synthesis, and disrupting key enzymes in bacterial metabolism.
Through the above share believe we get each drug, we more clearly in my heart, why we take medicine, drug after what happened in our bodies, and we have also seen drugs and poisons are inseparable, so you must be careful, rational drug use, finally thank you for your support I wish you all healthy
