Methadone is an opioid medication sometimes referred as a narcotic. The drug is used to reduce withdrawal symptoms for people undergoing detoxification for heroin and other narcotic drugs. Methadone does not produce “high” sensation which often associated with drug addiction.
Also, methadone is commonly used as a pain reliever. It serves as an important medication in the detoxification process. Methadone is only available in selected certified pharmacies.
Quick Facts :
- In a study of the Drug Enforcement Administration:
- From the year 1999 to 2005, overdose deaths because of methadone increased around 460%
- In 2011, records shows that over 65,000 emergency room visits were related to methadone abuse.
- About 2.5 million people ages 12 years old and above abused methadone in some point in their life in 2012. The number grew from 2.1 million in just one year.
History
Scientists working in I.G. Farbenindustrie AG at Farbwerke Hoechst in Germany developed methadone in 1937. During those times, Germany suffers from opium shortage problem and scientists have to think a way to solve it.
Bockmühl and Ehrhart filed for a patent for a synthetic drug similar to morphine on September 11, 1941. They called the drug Hoechst 10820 or Polamidon. During the WWII, methadone was widely used in Germany.
After the war, the US Department of Commerce Intelligence under the Technical Industrial Committer of the US Senate brought methadone in the US. Their investigation revealed that even though methadone contains addictive properties, it offers less sedation and respiratory distress than morphine. After the war, ten years later, Eli Lilly introduced the drug into the US.
What causes addiction?
Like other opiates, methadone acts in the brain opioid receptors which control the reward system function. Even though methadone is used as a medical management treatment for heroin addiction, it also contains potential characteristics for addiction. The problem with patients is that from heroin addiction, they often develop methadone addiction.
What are the signs and symptoms of addiction?
Methadone which contains 22-hour half-life acts longer but is less potent than heroin. Because of these properties, experts use methadone to treat withdrawal symptoms.
The use of methadone for opioid addiction is called as Methadone Maintenance Therapy or MMT. The treatment only transpires in a certified methadone clinic. However, even if methadone is used for medical treatment of opiate addiction, it also contains properties that make it prone to abuse.
Signs of addiction include:
- Using the drug more that the prescribed dosage
- Taking the drug outside of prescriptions. Clinics generally require the user to take methadone inside their facility, but some can buy it elsewhere like on the black market
- “Doctor shopping”, a behavior for getting legal prescription from different doctors
- Skipping schedule drug intake to have a ‘stockpile’ for high-dose administration later
- Ignoring responsibilities at work, school, and even relationships
- Physical Signs of Methadone addiction include:
- Constipation
- Constricted pupils
- Increased pain
- Nausea
- Slowed breathing
- Sweating
- Vomiting
Short-Term Effects
The effects of methadone are somewhat similar to heroin but longer-lasting and less intense. It usually lasts up to 24 hours; heroin lasting effects reach up to 2-3 hours. Methadone also slows down a person’s reaction, which makes movements more exaggerated or lethargic. This makes the user prone to accidents since they cannot respond quickly enough.
- Feelings of euphoria
- Drowsiness
- Nausea
- Pinpoint pupils
- Relaxation
- Respiratory distress
- Sedation
Long Term Effects
Around 5,000 people die because of methadone abuse annually. This commonly happens when users mix the drug with other substances such as alcohol and benzodiazepines.
Health complications from methadone abuse vary because of the genetic make-up of each individual, length of time which they used the substance even the duration of the intake. Prolonged methadone abuse can result in devastating effects on the overall well-being of the user. Some of the long-term effects include:
- Impaired judgment
- Heart complications
- Sexual dysfunction
- Respiratory problems
Blood borne disease like HIV, Hepatitis C (related with multiple injection uses or in multiple doses as well as sharing of needles.)
Furthermore, long-term heavy use of the drug will build tolerance in the body. Users must take higher doses of methadone to get the same effect. This behavior often leads to overdose.
Overdose symptoms include:
- Breathing problems/shallow, slow breathing
- Hypotension or low blood pressure
- Twitching muscles
- Nausea
- Vomiting
- Cyanosis or bluish color of fingernails and lips
- Coma
