Physical dependence is usually managed by a slow dose reduction over a period of weeks, months or sometimes longer depending on the drug, dose and the individual. [6] A physical dependence on alcohol is often managed with a cross tolerant drug, such as long acting benzodiazepines to manage the alcohol withdrawal symptoms.
Substance dependence, also known as drug dependence, is a biopsychological situation whereby an individual's functionality is dependent on the necessitated re-consumption of a psychoactive substance because of an adaptive state that has developed within the individual from psychoactive substance consumption that results in the experience of withdrawal and that necessitates the re-consumption ...
drug sensitization or reverse tolerance – the escalating effect of a drug resulting from repeated administration at a given dose; drug withdrawal – symptoms that occur upon cessation of repeated drug use; physical dependence – dependence that involves persistent physical–somatic withdrawal symptoms (e.g., fatigue and delirium tremens)
Opioids cause physical dependence and treatment typically addresses both dependence and addiction. Physical dependence is treated using replacement drugs such as buprenorphine (sold as Suboxone in combination with naloxone) and methadone. [44] [45] Although these drugs perpetuate physical dependence, the goal of opioid maintenance is to provide ...
"Substance use pertains to using select substances such as alcohol, tobacco, illicit drugs, etc. that can cause dependence or harmful side effects."On the other hand, substance abuse is the use of drugs such as prescriptions, over-the-counter medications, or alcohol for purposes other than what they are intended for or using them in excessive ...
The expense of opioid replacement treatments in some countries has led some people to try treatments with limited evidence. At high doses, loperamide has been reported by some drug users to alleviate opioid withdrawal syndrome. [31] The doses reported in the literature are associated with a high risk of damage to the heart. [32]
Chemistry, not moral failing, accounts for the brain’s unwinding. In the laboratories that study drug addiction, researchers have found that the brain becomes conditioned by the repeated dopamine rush caused by heroin. “The brain is not designed to handle it,” said Dr. Ruben Baler, a scientist with the National Institute on Drug Abuse.
[4] [3] Responses to a drug cue can be physiological (e.g., sweating, salivation, brain activity), behavioral (e.g., drug seeking), or symbolic expressive (e.g., craving). [3] The clinical utility of cue reactivity is based on the conceptualization that drug cues elicit craving which is a critical factor in the maintenance and relapse to drug use.
