The estimated median effective dose (ED 50) for SERT occupancy hence was 98.1 mg, which was associated with a plasma tramadol level of about 330 ng/mL (1,300 nM). [99] The estimated maximum daily dosage of tramadol of 400 mg (100 mg q.i.d. ) would result in as much as 78.7% occupancy of the SERT (in association with a plasma concentration of ...

Tramadol/paracetamol, also known as tramadol/acetaminophen and sold under the brand name Ultracet among others, is a fixed-dose combination medication used for the treatment of moderate to severe pain. [3] [4] It contains tramadol, as the hydrochloride, an analgesic; and paracetamol an analgesic. [3] [4] It is taken by mouth. [3] [4]
Celecoxib/tramadol sold under the brand name Seglentis, is a fixed-dose combination of the anti-inflammatory celecoxib and the opioid tramadol used for the management and treatment of pain. [ 1 ] Developed by Spanish pharmaceutical company Esteve , it was approved for medical use in the United States in October 2021.
Tramadol has several enantiomers, and each forms metabolites after processing in the liver. 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 ...
Paracetamol's bioavailability is dose-dependent: it increases from 63 % for 500 mg dose to 89 % for 1000 mg dose. [6] Its plasma terminal elimination half-life is 1.9–2.5 hours, [ 6 ] and volume of distribution is roughly 50 L. [ 132 ] Protein binding is negligible, except under the conditions of overdose, when it may reach 15–21 %. [ 6 ]
In pharmacology, a dirty drug is an informal term for drugs that may bind to many different molecular targets or receptors in the body, and so tend to have a wide range of effects and possibly adverse drug reactions.
