How do pain killers work? What are their side effects?

Painkiller, as indicated by the word itself, diminishes, eliminates or kills pain in body.  There can be various routes to administer painkillers. Few of them are mentioned as follows:
  1. Via injection, such as morphine,
  2. Orally in small quantities like NSAIDS. Oral forms can be syrups, capsules, or tablets.
  3. Sometimes these painkillers are injected rectally. In that case they are known as suppositories.
  4. Topically, in the form of an ointment, cream or gel. It is used mostly when the pain is superficially for example in muscles or skin
There are three types of painkillers. All three of them have different mechanisms and different means of activations. But how do they actually work, is a very common question.
  1. Paracetamol: Paracetamol’s effect is directed towards the brain. It blocks the pain origination and conduction from its source. It reduces prostaglandins formation, which is an inflammatory product responsible for pain origination. These inflammatory chemicals can be found throughout the body but are mainly found in brain. It can help relieve you from pain and also sidelines fever. Paracetamol is comparatively a safe drug to consume with minimum side effects if properly taken. Liver damage only occurs when the use is prolonged or the drug overdosed.
  2. NSAIDS:  Nsaids include ibuprofen and aspirin. They also inhibit the formation of inflammatory chemicals that are prostaglandins, but not by targeting in brain; instead they target its inhibition in the whole body. As they do not produce their effect in brain, they disturb various bodily functions and organs while they inhibit prostaglandins throughout the body. So if you are taking an NSAID for stomach pain, the target is your stomach lining. There are minor side effects from nsaids, which is not always necessary. Life threatening side effects are rare e.g. Stomach bleeding, Heart problems and Bleeding in gut.
  3. Opiods: Drugs belonging to this family, target their effects on the receptors located mainly in the brain and gut. They may also work on different receptors at different areas in the body. They not only reduce pain but also increase the pain threshold. If a person is addicted, consult your doctor. Common side effects are Nausea, Constipation, Vomiting, Dry mouth, Drowsiness and confusion.
