The most common adverse effects of tramadol include nausea, dizziness, dry mouth, indigestion, abdominal pain, vertigo, vomiting, constipation, drowsiness, and headache. [36] [37] Other side effects may result from interactions with other medications. Tramadol has the same dose-dependent adverse effects as morphine including respiratory ...
[3] [4] It is around half the potency of morphine as an analgesic, [5] [6] and has been widely used for the treatment of pain. [ 7 ] [ 8 ] Trimeperidine produces similar effects to other opioids, such as analgesia and sedation , along with side effects such as nausea , itching , vomiting , and respiratory depression which may be harmful or fatal.
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.
Few studies have investigated the effects of morphine on motor abilities; a high dose of morphine can impair finger tapping and the ability to maintain a low constant level of isometric force (i.e. fine motor control is impaired), [44] though no studies have shown a correlation between morphine and gross motor abilities.
Tramadol and tapentadol carry additional risks associated with their dual effects as SNRIs and can cause serotonin syndrome and seizures. Despite these risks, there is evidence to suggest that these drugs have a lower risk of respiratory depression compared to morphine.
Hydromorphone is extensively metabolized in the liver to hydromorphone-3-glucuronide, which has no analgesic effects. As similarly seen with the morphine metabolite, morphine-3-glucuronide, a build-up in levels of hydromorphone-3-glucuronide may produce excitatory neurotoxic effects such as restlessness, myoclonus and hyperalgesia. Patients ...
An opioid overdose is toxicity due to excessive consumption of opioids, such as morphine, codeine, heroin, fentanyl, tramadol, and methadone. [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]
