[citation needed] Closely related to morphine are the opioids morphine-N-oxide (genomorphine), which is a pharmaceutical that is no longer in common use; [citation needed] and pseudomorphine, an alkaloid that exists in opium, form as degradation products of morphine. [citation needed]
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 ...
For example, the narcotic levorphanol is 4–8 times stronger than morphine, but also has a much longer half-life. Simply switching the patient from 40 mg of morphine to 10 mg of levorphanol would be dangerous due to dose accumulation, and hence frequency of administration should also be taken into account.

Opioid dose conversions may be necessary when switching medications given the differing pharmacodynamics between opioids. Generally, parenteral (IV or IM) morphine is used as the standard for converting between opiates to achieve equivalent analgesic effects.
Endogenous opioids (enkephalins, dynorphin, endorphin) do not bind specifically to any particular opioid receptor. Receptor binding of the opioid causes a cascade leading to the channel opening and hyperpolarization of the neuron. The opioid receptors have the following channel types: mu, K + channel; l delta, K + channel; kappa, Ca 2+ channel ...
Speedball, powerball, or over and under [1] is the polydrug mixture of a stimulant with a depressant, usually an opioid. The most well-known mixture used for recreational drug use is that of cocaine and heroin; however, amphetamines can also be mixed with morphine and/or fentanyl. A speedball may be taken intravenously or by nasal insufflation. [2]
