[10] [15] While not recommended in women who are breastfeeding, those who take a single dose should not generally have to stop breastfeeding. [16] Tramadol is converted in the liver to O-desmethyltramadol (desmetramadol), an opioid with a stronger affinity for the μ-opioid receptor. [10] [17]
Baclofen, sold under the brand name Lioresal among others, is a medication used to treat muscle spasticity, such as from a spinal cord injury or multiple sclerosis. [8] [9] It may also be used for hiccups and muscle spasms near the end of life [9], and off-label to treat alcohol use disorder [10] [11] or opioid withdrawal symptoms. [12]
Brotizolam [3] (marketed under brand name Lendormin) is a sedative-hypnotic [4] thienotriazolodiazepine [5] drug which is a benzodiazepine analog. [6] It possesses anxiolytic, anticonvulsant, hypnotic, sedative and skeletal muscle relaxant properties, and is considered to be similar in effect to other short-acting hypnotic benzodiazepines such as triazolam or midazolam.

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.
Nefopam is contraindicated in people with convulsive disorders, those that have received treatment with irreversible monoamine oxidase inhibitors such as phenelzine, tranylcypromine or isocarboxazid within the past 30 days and those with myocardial infarction pain, mostly due to a lack of safety data in these conditions.
(+)-Desmetramadol is a G-protein biased μ-opioid receptor full agonist. [4] It shows comparatively far lower affinity for the δ-and κ-opioid receptors. [5]The two enantiomers of desmetramadol show quite distinct pharmacological profiles; [6] both (+) and (−)-desmetramadol are inactive as serotonin reuptake inhibitors, [7] but (−)-desmetramadol retains activity as a norepinephrine ...
These tramadol variants have varying activities at the μ-opioid receptor, the norepinephrine transporter, and the serotonin transporter, and differing half-lives, with the metabolites having the best activity. Using tramadol as a starting point, the team aimed to discover a single molecule that minimized the serotonin activity, had strong μ ...
