Opiates
The term opiate refers to the alkaloids found in opium, an extract from the seed pods of the opium poppy (Papaver somniferum L.). It has also traditionally referred to natural and semi-synthetic derivatives of morphine. The term is often incorrectly used to refer to all drugs with opium- or morphine-like pharmacological action, which are more properly classified under the broader term opioid.
The main opiates derived from opium are morphine, codeine and thebaine. Papaverine and noscapine are also present, but have essentially no effect on the central nervous system, and are not usually considered to be opioids. Papaveretum is a standardised preparation of mixed opium alkaloids used on cardiac patients.
Withdrawal and Treatment
Opiate withdrawal refers to the wide range of symptoms that occur after stopping or dramatically reducing opiate drugs after heavy and prolonged use (several weeks or more).
Opiate drugs include heroin, morphine, codeine, Oxycontin, Dilaudid, methadone, and others.
About 9% of the population is believed to misuse opiates over the course of their lifetime, including illegal drugs like heroin and prescribed pain medications such as Oxycontin.
These drugs can cause physical dependence. This means that a person relies on the drug to prevent symptoms of withdrawal. Over time, greater amounts of the drug become necessary to produce the same effect.
The time it takes to become physically dependent varies with each individual.
When the drugs are stopped, the body needs time to recover, and withdrawal symptoms result. Withdrawal from opiates can occur whenever any chronic use is discontinued or reduced.
Some people even withdraw from opiates after hospitalization for painful conditions without realizing what is happening to them. They think they have the flu, and because they don't know that opiates would fix the problem, they don't crave the drugs.
Symptoms of withdrawal include:
- Abdominal pain
- Agitation
- Diarrhea
- Dilated pupils
- Goose bumps
- Nausea
- Runny nose
- Sweating
- Vomiting
