Everyone's physique is different, and people with poor gastrointestinal absorption are not suitable for taking medicine directly.

In this case, it needs to be developed as an injection.

Some drugs will lose their activity in gastric acid, and capsules and injections are not good, so they must be developed as enteric-coated preparations...

This stage is also the beginning of drug development, which is collectively referred to as preclinical research.

After the preclinical research is completed, it will officially enter the human clinical trial stage.

This phase is further divided into four phases.

In short, it takes a long time for each new drug to be shipped to the human body from research and development to large-scale marketing.

A few years at the least, decades at the most.

Drugs like pineapple buns that do not require preclinical studies or human clinical trials and can act directly on the human body, except that nature can create this miracle.

Humans simply can't figure it out.

A group of people agreed, especially when they saw the wound at the beginning of summer, which was even deeper after the new flesh began to scab over.

At the same time, a deep sense of awe for nature also arises in my heart.

"Are you feeling unwell?" Professor Mo, whose eyes were not far from the wound, asked Xia Chu again.

Xia Chu was a little embarrassed and said, "Does itching count?" ”

"No, I'm talking about discomfort like numbness or pain in the wound."

"No, I don't feel anything other than itchy."

"Itching is a normal part of the wound healing process, when new nerve endings and blood vessels grow into connective tissue and local sensation is restored, and the wound becomes itchy.

Let the scab fall normally, don't pick the scab, and don't scratch the itch. "Baby

As he spoke, Professor Mo untied the gauze on her wrist, "Since there is no other discomfort, how about applying a layer here to make the injury heal quickly?" ”

Xia Chu was a little speechless, "You really don't worry about me at all, I think it's better to wait a few hours." ”

"Why wait?" Professor Mo asked rhetorically, "Don't you feel no discomfort except for itching?" ”

"Maybe it's because the time is too short, I'm resistant to the drug again, and the discomfort hasn't come out yet." Xia Chu laughed and pinched.

Professor Mo's answer was a roll of eyes, "If it were another wounded, I might really be worried, but you, I'm not worried at all." ”

"Why?"

Xia Chu's tone changed in shock, "Am I not human?" ”

Neither does it do that.

Just because she doesn't feel anything else doesn't mean you don't worry about her at all.

Just thinking about it, Professor Mo said, "You are human, but you are not an ordinary person." ”

"After the end of the world, I collected data on the bodies of the Anomalous, the Avisken, and the Mutant, and discovered an astonishing fact.

That is, the metabolism and self-renewal and recovery ability of cells are stronger than those of all humans, and their physique is too good to be true.

Even if the pineapple powder does have side effects, it won't take a few days for your physique to recover completely.

So, I have nothing to worry about. ”

At the beginning of summer, "···"

Xia Chu had nothing to say, she watched Professor Mo disinfect and sterilize the wound on her wrist, and then sprinkled a thick layer of medicinal powder on it, and didn't bother to bandage it, so she let the wound heal and scab under his old man's nose.

After the two injuries were scabbed, the old man finally showed mercy to Xiao Huang to let her go, and then picked up the unused pineapple bun and came to the man who was going to test the medicine.

"Xiaoqiu, Xia Yatou tried, I need to try it on you once, are you willing?"
