Objectives. To identify the medico-social and epidemiological peculiarities of HIV-infected people injecting drugs (PWID) at stage joining opioid substitution therapy (OST) program, who adopted it in 2019 city Minsk. Material methods. The data primary accounting documentation Health Care Institution «City Clinical Narcological Dispensary» Infectious Diseases Hospital» PWID patients were analyze...
In contrast to endogenous opioids, the highly addictive drug morphine activates the mu-opioid receptor without causing its rapid endocytosis. It has recently been reported that coapplication of low concentrations of [d-Ala(2),N-Me-Phe(4),Gly(5)-ol]-enkephalin (DAMGO) facilitates the ability of morphine to stimulate mu-opioid receptor endocytosis and prevents the development of morphine toleranc...
Pain is a common mode of manifestation of sickle cell disease (SCD) but there is limited information on pain management in this disorder. This study examines the use of opioids and non-opioid analgesia in the management of painful crisis in adult SCD patients; the routine use of antimalarials and antibiotics as adjunct therapy was also examined. A total of 87% of the patients had had a form of ...
Opioids modulate brain dopaminergic function in various experimental paradigms. This study used the rotational model of behavior in rats with unilateral 6-hydroxydopamine-induced lesions of the nigrostriatal pathway to investigate this interaction. Doses of two presynaptically acting dopaminergic drugs, amphetamine and cocaine, were coadministered with several doses of the mu opioid agonist, mo...
Opiates are indispensable for the treatment of moderate to severe pain. The gastrointestinal tract is one of the major victims of the undesired effects of opiates, because the enteric nervous system expresses all major subtypes of opioid receptors. As a result, propulsive motility and secretory processes in the gut are inhibited by opioid analgesics, and the ensuing constipation is one of the m...
The opioid system consists of three receptors, mu, delta, and kappa, which are activated by endogenous opioid peptides processed from three protein precursors, proopiomelanocortin, proenkephalin, and prodynorphin. Opioid receptors are recruited in response to natural rewarding stimuli and drugs of abuse, and both endogenous opioids and their receptors are modified as addiction develops. Mechani...
BackgroundSince the relief of pain in patients with acute myocardial infarction (AMI) is very important; we sought to assess the effect of Entonox as an analgesic drug in our subjects. Our goal was to compare the analgesic effect of Entonox with opioid drugs such as morphine and meperidine. MethodsThis study was a randomized clinical trial, which included 120 patients with wellestablished AMI a...
Rotation among opioids to minimize side effects and improve analgesia is a common clinical strategy in pain and palliative care. Methadone is frequently prescribed during opioid rotation, either by mouth or intravenously (IV) with patient-controlled analgesia (PCA) at home. However, there is a lack of consensus on rotation strategies from other opioids to methadone, as well as on conversion rat...
In this study, the activity of the delta-opioid receptor subtype-selective agonist, SB 227122, was investigated in a guinea pig model of citric acid-induced cough. Parenteral administration of selective agonists of the delta-opioid receptor (SB 227122), mu-opioid receptor (codeine and hydrocodone), and kappa-opioid receptor (BRL 52974) produced dose-related inhibition of citric acid-induced cou...
New effective analgesics are needed for the treatment of pain. Buprenorphine, a partial mu-opioid agonist which has been in clinical use for over 25 years, has been found to be amenable to new formulation technology based on its physiochemical and pharmacological profile. Buprenorphine is marketed as parenteral, sublingual, and transdermal formulations. Unlike full mu-opioid agonists, at higher...
