Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

558
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids01:24

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

605
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...

Drug Dependence01:17

Drug Dependence

1.4K
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...

Analgesia and Pain Management01:25

Analgesia and Pain Management

1.3K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Stimulants01:29

Stimulants

678
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...

Opioid Analgesics: Synthetic and Semisynthetic Opioids01:15

Opioid Analgesics: Synthetic and Semisynthetic Opioids

740
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

Area of Science:

  • Neuroscience
  • Psychiatry
  • Pharmacology

Background:

  • Cannabidiol (CBD) is increasingly recognized for its therapeutic potential in neuropsychiatric disorders.
  • Existing research highlights CBD's efficacy in managing psychotic symptoms, anxiety, and substance use disorders.
  • These conditions frequently co-occur with suicidality, yet dedicated suicide research involving CBD is notably absent.

Purpose of the Study:

  • To review the current evidence regarding cannabidiol's (CBD) effects on suicidality.
  • To explore potential factors contributing to the limited investigation of CBD in suicide research.
  • To propose directions for future research on CBD and suicidality.

Main Methods:

  • This study is a perspective piece, synthesizing existing literature.
  • It involves an overview of current research findings on CBD and related conditions.
  • Analysis of potential barriers to suicide-focused CBD research.

Main Results:

  • Significant research exists on CBD for psychosis, anxiety, and substance use disorders.
  • A considerable gap exists in the literature concerning CBD's direct impact on suicidality.
  • Potential reasons for this research gap are discussed.

Conclusions:

  • While CBD shows therapeutic promise for conditions linked to suicidality, its specific role in suicide prevention or treatment remains under-explored.
  • Further research is crucial to understand CBD's potential benefits and risks in the context of suicidality.
  • Recommendations are provided to guide future investigations into cannabidiol and suicide.
