Extended-release (or slow-release) formulations of morphine are those whose effect last substantially longer than bare morphine, availing for, e.g., one administration per day. Conversion between extended-release and immediate-release (or "regular") morphine is easier than conversion to or from an equianalgesic dose of another opioid with ...

Acute use (1–3 days) yields a potency about 1.5× stronger than that of morphine and chronic use (7 days+) yields a potency about 2.5 to 5× that of morphine. Similarly, the effect of tramadol increases after consecutive dosing due to the accumulation of its active metabolite and an increase of the oral bioavailability in chronic use.
After injection the used tube was often pinned to the receiving soldier's collar to inform others of the dose administered. [1] The syrette was adopted for use by the United States Army in 1940. [1] The US military also distributed atropine in syrettes. [citation needed] Chemical treatment was subsequently distributed in autoinjector form ...
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 ...
Fentanyl. 2 mg (white powder to the right) is a lethal dose in most people. [19] US penny is 19 mm (0.75 in) wide. Risk factors for opioid overdose include opioid dependence, injecting opioids, using high doses of opioids, and use together with alcohol, benzodiazepines, or cocaine. [1] [2] The risk is particularly high following detoxification. [1]
