Common side effects of morphine include drowsiness, euphoria, nausea, dizziness, sweating, and constipation. [12] Potentially serious side effects of morphine include decreased respiratory effort, vomiting, and low blood pressure. [12] Morphine is highly addictive and prone to abuse. [12]
Metonitazene is an analgesic compound related to etonitazene, [2] [3] which was first reported in 1957, [4] and has been shown to have approximately 1000 times the potency of morphine by central routes of administration, [5] but if used orally it has been shown to have approximately 10 times the potency of morphine. [6] Its effects are similar ...
To the contrary, in rats, (+)-morphine acts as an antianalgesic and is approximately 71,000 times more potent as an antianalgesic than (−)-morphine is as an analgesic. [ 1 ] (+)-Morphine derives its antianalgesic effects by being a selective-agonist of the Toll-like receptor 4 (TLR4), which due to not binding to opioid receptors allows it to ...
Its effects last for about four to six hours. Codeine exhibits abuse potential similar to other opioid medications, including a risk of addiction and overdose. [4] Common side effects include vomiting, constipation, itchiness, lightheadedness, and drowsiness. [4] Serious side effects may include breathing difficulties and addiction. [4]
Opiates, like heroin and morphine, decrease the inhibitory activity of such neurones. This causes increased release of dopamine in the brain which is the reason for euphoric and rewarding effects of heroin. [80] Both morphine and 6-MAM are μ-opioid agonists that bind to receptors present throughout the brain, spinal cord, and gut of all mammals.
Nicomorphine's side effects are similar to those of other opioids and include itching, nausea and respiratory depression.It is considered by doctors to be one of the better analgesics for the comprehensive mitigation of suffering, as opposed to purely clouding the noxious pain stimulus, in the alleviation of chronic pain conditions.

Side effects of diacetyldihydromorphine are similar to those of other semi-synthetic opiates and fully synthetic opioids, and the most commonly reported side effects include drowsiness, nausea, and constipation. Compared to morphine, diacetyldihydromorphine produces far fewer side effects which are also often lower in intensity.
