Caused by a biochemical reaction of the brain to stimuli to nerves from any part of the body. Pain can be one of the most difficult symptoms to cope with when we have an illness or accident of any kind.
That is why medical science has put a great deal of effort into creating medications that help alleviate pain. Today we will talk about one of the most important medicines to prevent and relieve pain, which has a unique characteristic, it is not an analgesic but an anesthetic. That’s right, we are talking about lidocaine.
What is lidocaine? The first thing you should know is that lidocaine is not a pain reliever but an anesthetic, that is, this medication helps prevent pain by anesthetizing the area. This by blocking the tactile sensitivity of a certain area of the body. And is that lidocaine is used as a local anesthetic because it only blocks sensitivity at the superficial level so it is used for superficial surgeries. One of the branches of medicine that use it the most is dentists for tooth surgeries or dental extractions.
How is lidocaine applied?
There are two common ways to use lidocaine, one of which is injected, which is applied to the area to be anesthetized or in the form of a regional block. Dentists often apply it to the denture area to numb the denture. Another way in which lidocaine can be applied is through sprays and creams. In the form of sprays or creams, it is used to numb the skin in small parts, such as the toes.
What are the benefits of lidocaine?
One of the main benefits of lidocaine is the fact that anesthesia is applied only to certain parts or regions of the body. This, unlike total anesthesia, poses far fewer health risks. And it is that total anesthesia, under certain medical conditions, can trigger serious problems such as cardiorespiratory arrest. In the case of lidocaine, it reduces the risk of suffering some type of complication caused by general anesthesia in your body.
The effect works quickly
If you have ever been given anesthesia based on this medication, you should know that the effect passes quickly compared to much more powerful medications. Dentists, for example, often tell their patients that the effect passes in a couple of hours.
You will not have to spend hours and hours lying in a bed without being able to move due to the effect of anesthesia. You will even be able to carry out your activities normally, although with more care, because this drug is a powerful anesthetic that is rapidly eliminated by the metabolism of the liver.
You will remain aware
For those of us who have been under the influence of opium-based anesthetics or narcotics, their effect can be truly risky. This is because dizziness and confusion can cause an accident if you are not accompanied by someone else.
In the case of these local drugs, the side effect is much less in both intensity and duration. That is why a patient can walk out of the doctor’s office and can even manage to drive because the effect is locally, not throughout the body, which will keep him awake and alert.
It is very versatile
Relief of pain locally thanks to lidocaine is another great advantage since this anesthetic can be used almost anywhere on the body. This makes the drug much more versatile for different uses, the main ones being superficial surgeries.
You can use lidocaine as a cream to relieve pain of all kinds, for example, muscle pain. Similarly, it serves to delay ejaculation when it is included in the lubricant of the condom. Another use is in ointments or ointments for sore muscles or for back pain.
Is often used to treat arrhythmias
In addition to being used to anesthetize areas of the body by blocking the tactile or superficial sensitivity of the body, as well as reducing muscle pain or back pain, lidocaine is also used to treat arrhythmias.
By blocking the sodium channel of the myocardium, it is possible to treat ventricular arrhythmias, especially acute ischemic arrhythmias. On the other hand, it is not usually used in atrial arrhythmias. In this way, lidocaine is used more than for pain relief in sore muscles, gums, etc.
What are the potential issues with lidocaine?
It is necessary to know the contraindications of lidocaine in order to know how to use it with much greater safety. The first is not to use this drug if you are allergic to local anesthetics from the amide family.
If you have regional ischemia problems or lidocaine hypersensitivity are other important points to consider. Also, if there is inflammation in the area where it will be applied then you should consider that lidocaine cannot be applied, even if it is in cream to relieve pain due to inflammation.
Where can I buy lidocaine?
While this medication is usually regulated, in space in liquid to inject format, there are some ways to find lidocaine over-the-counter. For example, a popular provider of creams called lidocaína crema in Spanish is made by Blue-Emu. These types of creams are mainly used for back pain or ointment for muscle pain, being common to find this anesthetic with anti-inflammatory and other medications.
On the other hand, we can find that this medicine is also included in some types of condoms, as well as it is usually marketed as a spray to use, for example, in body piercings or even by podiatrists. In this way, lidocaine is one of the most widely used drugs for its versatility and effectiveness.
