CNS Stimulants: Cocaine, Amphetamines and Cannabinoids01:24

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

910
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...

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

793
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,...

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Continuing Care

2.0K
Continuing care describes the variety of health, personal, and social services provided over a prolonged period. The need for continuing care is increasing because people are living longer. Many people do not have families or others to care for them. Continuing care is mainly for patients who are disabled, functionally dependent, or suffering from a terminal disease. It is available within institutional settings or in homes. Examples include nursing centers or facilities, assisted living,...

Summary
This summary is machine-generated.

Medicinal cannabis shows potential for symptom relief in palliative care, but clinical data for pain and nausea remains inconclusive. Further clinical trials are needed to establish its efficacy and guide safe use.

Area of Science:

  • Palliative Care
  • Symptom Management
  • Medicinal Cannabis Research

Background:

  • Palliative care is increasingly integrated earlier in disease trajectories to improve survival and function.
  • Strong public interest exists for medicinal cannabis, especially in palliative diagnoses.
  • The endocannabinoid system offers potential for symptom modulation, but clinical evidence is limited.

Purpose of the Study:

  • To review the current evidence and considerations for using medicinal cannabis in palliative care.
  • To highlight the need for rigorous clinical trials to inform practice.
  • To discuss the safe use of unregistered products or off-label prescribing.

Main Methods:

  • Review of existing clinical data and evidence for medicinal cannabis in palliative symptom management.
  • Analysis of challenges in extrapolating data from other settings (e.g., chemotherapy-induced nausea).
  • Consideration of pharmacokinetic, pharmacodynamic, and drug-drug interactions for refractory symptoms.

Main Results:

  • Clinical data on medicinal cannabis for key palliative symptoms like pain and nausea is inconclusive.
  • Evidence from other settings is not readily transferable to palliative care populations.
  • Potential benefits require further investigation within controlled clinical trials.

Conclusions:

  • Exploration of medicinal cannabinoids should ideally occur within clinical trials to build a robust evidence base.
  • Use of unregistered products or off-label prescribing requires careful consideration of interactions and patient benefit.
  • Informed patient discussion and regular review are crucial for managing refractory symptoms with medicinal cannabis.
