Painkillers or analgesics are pain relief medications that help get rid of pain either by reducing inflammation or by blocking pain signals. There are two basic types of pain relievers such as opioids (e.g., codeine, morphine) and non-opioids (e.g., acetaminophen, ibuprofen). Non-opioids work by preventing enzymes from causing inflammation, while opioids combine with receptors in the brain to change the sense of pain.

Painkillers are medicines used to lessen soreness and calm pain caused by injury, after surgery, a toothache, or a headache. They reduce pain by working in different ways, such as by inhibiting the body from producing pain-sensitive chemicals. They can also relieve pain by stopping pain signals in the spinal cord and brain. Common types of pain-soothing medicines include NSAIDs, such as ibuprofen, which reduce inflammation. They stop enzymes called cyclooxygenase (COX) from producing pain chemicals called prostaglandins.
And opioids work by blocking pain messages in the brain and spinal cord. This process changes how the brain understands pain signals, making the pain feel less intense. The mechanism of painkillers such as paracetamol is to reduce pain signals in the brain and is not an anti-inflammatory painkiller. This blog narrates what painkillers are, how they work, how they should be used safely, and what benefits and side effects they have. Let’s have an overview.
What are the Different Types of Pain Medicines?
A wide range of painkillers is available today for pain management and delivering comfort in a short time. There are primarily three types, and all of them work differently. They are as follows:
-
NSAIDS
-
Weak Opioids
-
Strong Opioids
Examples of NSAIDs are naproxen, diclofenac, and ibuprofen. Aspirin also belongs to the NSAID family, but it is mainly recommended in low doses. It helps prevent blood from clotting and is especially used by people experiencing heart attack issues.
Weak opioids and strong opioids (sometimes called opiates). Weak opioids are dihydrocodeine and codeine. Although commonly known as 'weak opioids', they are highly effective analgesics to manage your pain. However, they may cause severe dependence and ultimately adverse effects, so they should not be taken lightly.
The family of strong opioids comprises buprenorphine, pethidine, morphine, tramadol, and oxycodone.
Different types of painkillers are sometimes blended in one tablet, for instance, codeine and paracetamol, referred to as co-codamol.
Moreover, some antiepileptic medicines and antidepressants are also used to treat neuropathic pain.
Important Considerations
Types of Pain: Different pain relievers can heal different types of pain, such as chronic pain from a long-term condition or acute pain from an injury.
Availability: Many common painkillers are used to treat pain, such as over-the-counter medicines, while more potent medicines like opioids need a recommendation.
Side Effects: Opioids have a higher risk of dependency and other side effects, such as constipation, sleepiness, and slowed breathing, requiring careful monitoring. NSAIDs can upset the stomach lining, so they are often suggested to be taken with or after food.
Consult a Healthcare Provider: It is important to talk to your doctor or GP to recommend the most effective and safe type of pain medication for your particular needs.
How Do Painkillers Work in the Body?
The main function of NSAIDs is to block the effect of chemicals (enzymes) called cyclooxygenase (COX) enzymes. COX enzymes help produce other chemicals called prostaglandins. Prostaglandins are sensitive to pain and inflammation at sites of damage or injury. A reduction in prostaglandin production lessens both pain and inflammation. Not all NSAIDs are the same, and some work in slightly different ways from others.
The working principle of paracetamol is not yet known. But it is thought to work by inhibiting COX enzymes in the brain and spinal cord (central nervous system). Paracetamol is used to lower a high temperature and treat pain. However, it does not reduce inflammation.
The working mechanism of opioids is by combining with certain receptors (opioid receptors) in the central nervous system, the gut, and other parts of the body. It leads to a decrease in the way pain is felt and responded to, and it increases tolerance to pain.

Which Painkillers are Usually Recommended?
The type of painkiller a doctor will suggest is based on:
-
The type of pain
-
Any other health problems
-
The severity of the pain
-
The possible side effects of the medicines
Pain relief medicines, such as paracetamol, are normally advised if the pain is mild or moderate and there is no inflammation.
NSAIDs are usually recommended to people suffering from pain along with inflammation - for example, muscles (back pain) or arthritis (pain in the joints). Also, keep in mind that NSAIDs can cause several possible side effects, and they are not appropriate for everyone. For instance, they are not suitable for people who have or have had stomach ulcers. In this case, a doctor may recommend a safer medicine (paracetamol) even though it may not work as well. NSAIDs can be used with heat and ice treatment in ligament injuries, joints, or muscles.
Weak opioid painkillers are generally suggested for more severe pain or if other painkillers are not working.
Stronger opioids are usually advised to treat severe pain, such as pain after an operation, cancer-related pain, or after a serious injury.
Anti-inflammatory medicines used as a cream (topical painkillers) are specifically used to calm pain in the muscles and soft tissues.

Who Cannot Take Painkillers?
Anyone may suffer from pain at any stage of life, but painkillers are not for everyone. The primary reason why a painkiller might need to be avoided is following an allergic reaction to a particular type of pain reliever or some serious side effects. Even if it has happened, a different type of painkiller will usually be available.
Aspirin is never recommended for children under the age of 16 years, because there is a very small risk of the child developing a serious condition called Reye's syndrome. Similarly, painkillers are not for people who have:
-
A head injury.
-
A condition that causes fits or seizures.
-
Lung problems or breathing difficulties.
-
Adrenal gland problems.
-
Regularly drink more than the maximum recommended amount of alcohol.
