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 ...
Activation of the μ-opioid receptor by an agonist such as morphine causes analgesia, sedation, slightly reduced blood pressure, itching, nausea, euphoria, decreased respiration, miosis (constricted pupils), and decreased bowel motility often leading to constipation. Some of these effects, such as analgesia, sedation, euphoria, itching and ...
"Since the drug is a synthetic, it is easier to produce — unlike heroin, which is dependent on a plant like opium." Carfentanil is 10,000 more times more potent than morphine and 100 times more ...

It is a strong μ-receptor agonist that is 80–100 times more potent than morphine, and has a fast onset with a shorter duration of action than morphine due to redistribution from CNS location to fatty tissue. When it is used as a continual drug (e.g. transdermal patches, longer term use of IV fentanyl in ICU patients) its elimination half ...

[3] [5] This preventable pathology can be fatal if it leads to respiratory depression, a lethal condition that can cause hypoxia from slow and shallow breathing. [3]
