Drugs Acting on Autonomic Ganglia: Stimulants01:23

Drugs Acting on Autonomic Ganglia: Stimulants

1.5K

Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...

CNS Depressants: Alcohol and Nicotine

334
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

Drug Dependence

1.1K
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

Drug Abuse and Addiction: Pharmacological Phenomena

634
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Stimulants01:29

Stimulants

285
Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

212
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Area of Science:

  • Addiction Medicine
  • Behavioral Health

Background:

  • Nicotine addiction receives less attention than other substance use disorders.
  • Patients often feel discouraged by previous failed quit attempts, leading to reluctance in seeking treatment.

Purpose of the Study:

  • To highlight the low priority of nicotine addiction treatment.
  • To explain patient reluctance to quit due to discouragement.
  • To propose applying interventions from other substance use disorders to nicotine addiction.

Main Methods:

  • The study reviews current approaches to addiction treatment.
  • It analyzes psychological barriers to quitting nicotine.
  • It suggests adapting established clinical interventions for nicotine dependence.

Main Results:

  • Discouragement is a key factor in patients remaining in the Precontemplation stage of change.
  • Traditional interventions used for other substance use disorders can be effective for nicotine addiction.

Conclusions:

  • Prioritizing nicotine addiction treatment is crucial.
  • Addressing patient discouragement is essential for successful quitting.
  • Adapting existing SUD interventions can enhance nicotine addiction treatment outcomes.
