All medicines are divided into pharmacologic groups to which they share similar pharmacological action or generating substance. To the group of analgesics are narcotic drugs: "Morphine", "Morphine", "Fentanyl" and "Omnopon" in the pharmacy can not buy, and it is not necessary. For other drugs that are traditionally considered to be analgesics, anesthesia is usually not essential. Non-narcotic analgesics is a nonsteroidal anti-inflammatory drugs, which include several subgroups, located below the principle of efficiency: from smallest to largest.
Pyrazolones — quite old pharmaceutical group, which is not inferior to their positions because of the low cost drugs. This group includes several active substances that pharmacies can be found under different names: Metamizole sodium (Analgin, "Baralgin", "Tempalgin") and propyphenazone, the brand name coincides with the current component. It should be noted that drugs containing Metamizole, banned in most countries of the world.
Derivatives of salicylic acid — another old inhabitant of the kits. The most common active substance of this group — acetylsalicylic acid ("Aspirin", "Accardo", "Cardiac", "Thrombotic ass", "upsarin UPSA"). This group belongs mesalazine ("salofalk worth us", "Pentas"). These drugs have anti-inflammatory and antipyretic effect, and drugs acetylsalicylic acid also reduce blood viscosity and prevent blood clots.
Anilide is a long — known group, but its use is for ingesting, and not the analgesic effect because these drugs have a toxic effect on the liver. The main anilide is paracetamol, its counterparts — "Antigrippin", "Panadol", "Set", "Used".
Acetic acid derivatives and related compounds is one of the most popular nowadays groups of drugs. These include the active substances and preparations: Ketorolac ("Ketorol", "Ketorolac", "caution"), aceclofenac ("Airtel"), diclofenac ("Voltaren", "Ortofen", "Ortofen", "Diklovit", "Ortofleks"), indomethacin ("Indows", "Indocid", "Indated", "Indomethacin"). The popularity of these drugs due to their high efficiency and broad spectrum indications: pain in muscles and joints, dental pain, painful menstruation and trauma.
Derivatives of propionic acid, despite its apparent simplicity and long acquaintance with them, the drugs work well and quickly cropped the pain: ibuprofen ("Brufen", "Ibufen", "Nurofen", "MiG"), Ketoprofen (Ketonal", "Fastum gel", "Flomax"), naproxen ("Nalgesin", "Pronexin", "Anaprox").
Oxicam — modern group of non-steroidal anti-inflammatory drugs, which are most effective for rheumatic, muscle and joint pains. These include meloxicam ("Amelotex", "Artrozan", "Melflex"), tenoxicam ("Examen", "Tinicum"), piroxicam ("Finalgel", "Rimador"), lornoxicam ("Xefocam", "Xefocam rapid").
Coxib — another modern group that rescues many patients suffering from severe arthritis, arthrosis and spondylitis. In this group you should pay attention to etoricoxib ("Arcoxia") and celecoxib ("celebrex").
All of these drugs have anti-inflammatory and antipyretic activity. By blocking mediators of inflammation they reduce swelling, which often occurs the pain: swollen tissues compress the nerve endings, causing pain. All nonsteroidal anti-inflammatory drugs have a side effect that you need to be careful irritant action on the mucous membrane of the stomach, which can cause exacerbation of gastritis or peptic ulcer disease.
There is another group analgesics — opioid analgesics. These drugs are prescribed only by a physician and dispensed strictly according to the recipe. Because they are very strong analgesics, they are usually used in cancer patients and after surgery. This group includes "Tramadol", "Naloxone", "Naltrexone", "Stadol" and "Nalbuphine".
There is such a thing as a neuropathic pain arises not because of objective stimulation of neurons due to injury, swelling or inflammation. Neuropathic pain occurs due to abnormal excitation of neurons (the people called pain receptors), although the reasons for pain there. For treatment of such pain used drugs is not entirely typical of the group. This is due to the fact that these drugs are able to act directly on neurons and remove their excitement. We are talking about anti-epileptic drugs: pregabalin (Lyrica "Algeria") and gabapentin (the"Gabagambi", "Tebantin", "Corvalis").
Of course, before you go to the pharmacy for medicine, you need to visit a doctor so he can prescribe you adequate pain medication. After all, you need to know what causes pain, and what drugs it is better to choose for such pain.
