Painkillers eliminate or reduce the sensation of pain. These include various chemical. the structure and mechanism of action of medicinal substances. The main place among them occupy the so called. Analgesics (analgesics), which alleviate pain as a result of the predominant action on the nervous system. There are drugs. In addition, non-narcotic. To drug include morphine preparations (morphine, omnopon) and its synthetic. Substitutes (promedol, fenadone, fentanyl, etc.). Narcotic analgesics suppress various pains, including very severe pains caused by injuries, burns, myocardial infarction. The drugs in this group also have a pronounced effect on the psyche, weakening negative emotions associated with pain (fear, anxiety, depression) and creating a feeling physical and crazy, comfort and well-being (so called euphoria).
Along with this, with the re-introduction of the drug analgesics in the same dose develops addiction (decrease in sensitivity to them), with Krom their analgesic effect is weakened and the subsequent increase in the dose of analgesic can lead to a painful addiction – drug addiction.
Therefore, narcotic analgesics are strictly registered and indications for their use are limited. The use of drugs analgesics without a doctor’s prescription is considered a criminal act, respectively punished.
To non-narcotic analgesics are different in chemical structure synthetic drugs (acetylsalicylic to-that, amidopirin, analgin, fenatse-tsin, paracetamol, etc.). Compared with the drug analgesics, they have less analgesic activity and effective for pain resulting from inflammatory damage of various organs and tissues (toothache, pain with arthritis, myositis, neuritis, etc.). In addition to the analgesic action, non-narcotic analgesics cause an antipyretic effect (see. Antipyretic drugs), and many of them also have an anti-inflammatory effect (see Anti-inflammatory drugs). Do not take these drugs without a doctor’s prescription.
There are cases of a dangerous violation of blood formation caused by long-term independent (without medical supervision) use of such drugs as analgin, amidopyrine, butadione, and phenacetin. Systematic uncontrolled intake of salicylic to-you drugs (acetylsalicylic to-you and sodium salicylate) can cause damage to the gastric mucosa, accompanied by bleeding, as well as tinnitus, hearing loss, weighting of certain diseases (bronchial asthma) etc.
The analgesic effect can also have a variety of drugs that do not belong to the group of analgesics. Therefore, the pain associated with spasm of smooth muscles of internal organs, reduced under the influence of antispasmodic, agents, i.e., smooth muscle relaxants, atropine, preparations of belladonna, papaverine, etc. for pain resulting from vasospasm accompanied by impaired blood supply to individual organs, vasodilators are effective; in particular, pains at stenocardia are weakened by drugs that improve blood circulation in the heart (validol, nitroglycerin), headaches associated with an increase in blood pressure, – antihypertensive drugs; with abdominal pain caused by the accumulation of gas in the intestine, so-called effective. carminatives that promote the release of gases from the intestines, or carbol – a drug that absorbs them. The action of these funds is aimed at eliminating the cause of pain. To effectively usethese kinds of drugs, you need to consult a doctor to find out the cause and nature of pain.
In a situation where there is a question about whether or not to take medicine, there is no question of completely stopping to drink medicine and stoically endure any pain. Just do not swallow pills for any reason. Of course, there are situations when pain arises inappropriately, threatening to destroy our important plans, or when it is so strong that it is more harmful for the body to tolerate it than to drink medicine. For such cases, painkillers, which are sold in pharmacies in the non-prescription department, are intended. However, in other situations, at the first sign of pain, it is better to first think about its possible causes. Sensations are the language in which our body communicates with us, and it is worth listening to. If we pay attention to these “messages”, we will be able to prevent many serious health problems.
