What Are Opiate / Opioid Painkillers?

What are Opiates?

Opiates are narcotic analgesics that act as central nervous system depressants. They are generally divided into two types – natural and synthetic. A natural opiate is one that has been made from the milky fluid of the poppy. This liquid is air-dried to produce what we know as opium. Synthetic opiates are man-made drugs that have a comparable chemical make up to natural opiates but are manufactured in industrial laboratories. The collective term for both natural and synthetic opiates is opioids. Heroin is the most commonly used opioid.

How Do Opioids Work?

Opioids connect with proteins in the brain, gastrointestinal tract and spinal cord, which we call opioid receptors, Different opioid drugs will attach to different receptors to stop pain messages getting to the brain. These drugs can also relieve stress and make users feel drowsy or content. This is because they induce euphoria in the parts of the brain that mediate pleasure, Other effects can include reduced heart rate, constipation, widened blood vessels and depressed coughing and breathing.

What Are Opiate / Opioid Painkillers?

Opioid painkillers include buprenorphine, codeine, dihydrocodeine, methadone, morphine and diamorphine (more commonly known as heroin). A lot of these drugs are only available on prescription from a doctor. Some are found in over-the-counter medicines in low doses, normally mixed with paracetamol, ibuprofen or aspirin.

Although opioid painkillers are generally safe to take, some people can become dependent on them and they are highly addictive. When they are used mainly to get high or to feel better, the chances of addiction will be much higher.
