The characteristics of isoniazid
Isoniazid was highly selective and had a strong antiseptic effect on the bacteria. It could suppress the synthesis of mycolic acid in the wall of the fungus, causing the bacteria to lose its acid resistance, its water affinity, and its ability to proliferate. Isoniazid has a disinfecting effect on active phase of the growth of active phase of the bacteria, and only has an suppressive effect on the stationary phase of the bacteria. In addition, isoniazid could permeate into the cells and also had a disinfecting effect on bacteria inside and outside the cells. It was an all-purpose disinfectant and had little effect on other bacteria. However, when isoniazid was used alone, the bacteria were prone to resistance.
The mechanism of isoniazid
The mechanism of action of isoniazid was not completely clear, but the following conclusions were made: isoniazid was a synthetic antiseptic that had a specific effect on the bacteria. Its effect may be carried out in a variety of ways, including hindering the synthesis of Phospholiptides and mycolic acid in the cell wall of the M. tubers, causing the bacteria to lose acid resistance and proliferate and die. In addition, isoniazid can also be oxided into isonicotinic acid in the bacteria, interfering with the growth of the bacteria. It could also combine with the NAD glucose protector to affect the synthesis of DNA, and combine with the copper ions required by the fungus to make the bacteria lose its activity and play an antiseptic role. In short, isoniazid has a disinfecting effect on M. tube-like bacteria through a variety of pathways.
The mechanism and pharmacology of isoniazid
Isoniazid's mechanism of action may be carried out in a variety of ways. First of all, it might cause the bacteria to lose its acid resistance and die by hindering the synthesis of phosphorus ester and mycolic acid in the cell wall of the M. tubers. Secondly, isoniazid was oxided into isonicotinic acid in the bacteria, which interfered with the metabolism process in the bacteria cells and inhibited the growth of the bacteria. In addition, isoniazid can also be combined with some of the bacteria required by the bacteria, so that the bacteria lose their activity, thereby playing an antiseptic role. Isoniazid was a synthetic antiseptic that was mainly effective against bacteria during the growth and reproduction period. It was active against both the cells and the cells. It was strong against the bacteria in the reproductive phase, but weak and slow against the bacteria in the stationary phase. Isoniazid's antiseptic effect had a high degree of selectively and specifically. It mainly had an antiseptic effect on the bacteria, but it had little effect on other bacteria.
The efficacy of isoniazid injections
Isoniazid injection was mainly used to treat various types of malaria. It had a strong antiseptic effect on the bacteria, and was one of the most powerful synthetic anti-malaria drugs. It could suppress the synthesis of the cell wall of M. tubers, thereby exerting an anti-tumor effect. Isoniazid injections were usually used in combination with other anti-inflammatory drugs for the treatment of all types of malaria, including lumbar distension and other infectious diseases. However, when using isoniazid injections, attention should be paid to the side effects that may cause liver function and nervous system. The doctor should follow the doctor's advice, monitor liver function regularly, and pay attention to clinical manifestations. In addition, isoniazid drugs are prone to drug interactions with other drugs.
Formula for the mechanism of isoniazid
The mechanism of isoniazid's action could be remembered through the following formula: " Bacteria-blocking wall, inhibition of nuclei, acidic oxidization, and copper binding." Specifically, isoniazid could hinder the synthesis of Phospholiptides and mycolic acid in the cell wall of M. tubers, causing the bacteria to lose its acidic state and die. It could also be oxided into isonicotinic acid in the bacteria, which inhibited the growth of the bacteria. In addition, isoniazid could also bind to the NAD glucose lysin's inhibition factor, affecting the synthesis of DNA. Finally, isoniazid can also combine with the copper ions required by some of the bacteria's antibiotics, causing the antibiotics to lose their activity and thus play an anti-inflammatory role.
What are the mechanisms of isoniazid?
Isoniazid's mechanism of action mainly included the following aspects: Inhibition of the synthesis of the DNA of the M. tubers, impact on the metabolism inside and outside the cell, killing the M. tubers, and other effects. Isoniazid can suppress the synthesis of mycolic acid in the bacteria, causing the cells to lose their acid resistance, proliferating power, and water affinity, and die. It could also interfere with the protein synthesis of the fungus, thus playing an anti-inflammatory role. In addition, isoniazid also had anti-inflammatory and anti-allergic effects, and had a certain treatment effect on diseases such as dry eye and hemorrhoid. It should be noted that the adverse reactions of isoniazid mainly include nervous system damage, liver toxicity, peripheral neuroinflammation, central nervous system toxicity, and blood system damage.
The mechanism of isoniazid in the video on malaria
Isoniazid was an anti-inflammatory drug. Its mechanism of action mainly included the inhibition of the synthesis of DNA from the bacteria, the metabolism inside and outside the cell, and the killing effect on the bacteria. To be specific, isoniazid could suppress the synthesis of the DNA of the M. tubers and interfere with its replication process, thereby achieving an anti-tumor effect. In addition, isoniazid could also suppress the protein synthesis of the bacteria, affecting the metabolism of the bacteria, and ultimately leading to the death of the bacteria. Isoniazid also had anti-inflammatory and anti-allergic effects. It also had a certain treatment effect on diseases such as dry eye and inflammation. In short, isoniazid plays a role through a variety of mechanisms and is one of the important drugs for the treatment of malaria.
Isoniazid's main function
Isoniazid's main function was to treat malaria. It has an antiseptic effect, mainly targeting the growth and reproduction of the MTB, and can kill or suppress the growth of MTB. In addition, isoniazid also has a certain suppressive effect on some other bacteria, such as candida candida, staph, and so on. It can also be used to treat diseases such as whooping cough and sty. Isoniazid was a widely used first-line anti-inflammatory drug. It had a good sterilization effect and few adverse reactions, and patients were usually easy to tolerate. In clinical treatment, isoniazid is often used in combination with other anti-inflammatory drugs to improve the treatment effect and prolong the time of drug resistance.
Main Toxic Effects of Isoniazid
The main toxic effects of isoniazid include liver damage and neurotoxicity. Isoniazid can damage liver cells, leading to elevation of transfusions, icterus, and liver cell death. When combined with rifampicin, the toxicity of the liver was significantly increased. In addition, isoniazid can also cause nervous system toxicity, manifested as peripheral neuroinflammation, abnormal sensation of limbs, loss of reflexes, muscle paralysis, and mental disorder. These adverse reactions may be related to a lack of B6.
Action mechanism and adverse reactions of isoniazid
Isoniazid was an anti-inflammatory drug that had a specific effect. It was only effective against the bacteria, but not against other bacteria. Its mechanism of action may be to suppress the synthesis of mycolic acid, causing the bacteria to lose acid resistance, proliferating ability, and repulsion, eventually leading to the death of the bacteria. Isoniazid could kill both the inside and outside of the engulfing cells. It was a full-course disinfectant. Isoniazid had a strong killing power for bacteria in the reproductive stage, but it was weak and slow for bacteria in the stationary stage. Common side effects of isoniazid included peripheral neuroinflammation, liver toxicity, and decreased white blood cells. Less common adverse reactions included male patients with laceration and mental and nervous system symptoms such as excitement, hyperactivity, and hallucinations.
Can Isoniazid Treat Lung Nodules?
Isoniazid could treat lung nodes. Isoniazid was the first choice for the treatment of lung cancer, and it had a strong suppressive and killing effect on MTB. Commonly used drugs for treating lung cancer include isoniazid, rifampicin, pyrazinamid, and ethambutal. Most of them would shrink or even disappear after receiving the appropriate medication. Therefore, there was no need to worry too much about small lung nodes caused by infection.
