The side effects include a lack of control over the substance, compulsive use and the presence of problems medical and social. Abrupt withdrawal triggers opioid-abs syndrome incontinence (physical dependence). The abstinence is flu-like, with yawning, mydriasis, rhinorrhea, muscle pain, sweating, piloerection, nausea and vomiting, diarrhea, fever, insomnia. It causes anxiety. It also presents a desire very intense for the drug (depending on psychic dependence or craving).
Discuss the changes in the populations of opioid users. Include in this discussion the debate around the availability of Naloxone.
It is estimated that opioid overdose kills around 15,000 Americans every year (Szalavitz).
Naloxone is a competitive antagonist of opioid receptors. It blocks predominantly mu receptors and, to a lesser extent, affects the other opioid receptors and eliminates the effect of both endogenous opioid peptides and exogenous opioids. Naloxone prevents, reduces or eliminates (depending on the dose and time of administration), the effects of opioid analgesics, restores breathing, reduces sedation and euphoria and reduces the hypotensive effect. A continuous debate is in progress regarding whether naloxone would lead to a “false sense of security” which may result in a corresponding rise in the usage of heroin. However, from the limited evidence the reverse seems to be true.
