Analgésicos y medicamentos para el dolor

Pain is part of the body's natural response to infection or injury; it lets us know something is wrong. Pain is usually the result of inflammation somewhere in the body. There are many different types of pain relief; different in how they are given (eg, gels, sprays, tablets) and different in how strong they are. Mild to moderate pain can be treated with paracetamol or non-steroidal anti-inflammatory drugs (NSAIDs) like aspirina o ibuprofeno. Severe pain is usually treated with an opioid painkiller such as tramadol, morfina o fentanyl. Opioid painkillers work best when used for short periods of time only. Long-term use of opioid painkillers can result in tolerance and dependence on the medicine. Nerve pain can be harder to treat and medicines such as pregabalin y gabapentina are usually tried first.
