  • Due to the high prevalence of depressive disorder, the antidepressant drugs have become one of the most common medications in western countries, with as an example of 6% of users in France [19]. (heraldopenaccess.us)
  • Traditionally, antidepressant research has focused on the development of drugs that bind to the serotonin transporter (SERT). (psychscenehub.com)
  • An enormous body of evidence reported particular neuroadaptations following chronic administration of antidepressant drugs. (heraldopenaccess.us)
  • A knowledge of the symptoms associated with each neurotransmitter can facilitate diagnostic evaluation in drug abuse and withdrawal states ( Table 2 ) . (aafp.org)
  • however, this weak serotonergic activity is not thought to be relevant with regard to the drug's analgesic activity. (medswow.com)
  • In this model, the signs and symptoms of drugs of abuse ( Figure 1 ) are organized around the activity of six neurotransmitters. (aafp.org)
  • While kratom or its related compounds have not been approved by the U.S. Food and Drug Administration as safe and effective for any medical use, people report using kratom products to alleviate drug withdrawal symptoms and cravings (particularly for opioids), to alleviate pain and to help manage mental health problems.

  • review drug interactions. (pdr.net)
  • These factors are further complicated by interactions related to multiple drug use, mixed intoxication-withdrawal states and idiosyncratic reactions. (aafp.org)
  • The multiple signs and symptoms of intoxication and withdrawal often are not consistent because of variable dosages and the adulteration of drugs. (aafp.org)
  • Like all drugs, kratom's effects may depend on the amount taken, potency (concentration and strength), formulation of the product, the way it is ingested, other drugs in a person's system, a person's underlying medical conditions, and a person's previous experience with the substance, among other factors. (nih.gov)
  • These opioidergic and noradrenergic activities are believed to account for the analgesic effects of the drug. (medswow.com)
  • [6] (Many of these symptoms may be side effects of the drug or drug interaction causing excessive levels of serotonin rather than an effect of elevated serotonin itself. (wikipedia.org)
  • These neurotransmitters act on their respective neuroreceptor sites to produce the clinical effects of the particular drug. (aafp.org)
  • The symptoms of drug abuse are frequently misdiagnosed. (aafp.org)
  • In this review, we describe major adaptive changes in pre- and post-synaptic 5-HT neurotransmission as well as alterations in gene transcription and neurotrophic factors in response to long-term treatment with conventional antidepressants, new putative ones or novel promising drug candidates, all acting via 5-HT system. (heraldopenaccess.us)
  • 5-HT is involved in descending inhibitory pathways in the CNS, and modulation of this system is the most likely mechanism of action of antidepressant drugs in analgesia. (researchgate.net)
  • There is little to choose between the different classes of antidepressant drugs in terms of efficacy, so choice should be based on the individual patient's requirements, including the presence of other existing disease and therapy, suicide risk, and previous response to antidepressant therapy. (pharmacologyeducation.org)
  • The mechanism of action of buspirone in treating sexual dysfunction may be reduction of serotonergic tone via stimulation of presynaptic autoreceptors or the alpha-2 antagonist effects of one of buspirone's major metabolites, 1-pyrimidinylpiperazine. (medscape.com)
