Ketobemidone (Cliradon, Ketogan, Ketodur, Cymidon) is a strong opioid analgesic, structurally related to pethidine, which has been in clinical use for more than 50 years. In the Scandinavian countries ketobemidone is only available in combination with a spasmolytic substance N,N-dimethyl-3,3-diphenyl-I-methylallylamine (A29). Ketobemidone has been shown to be a non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist. In spite of a relatively low mu-receptor affinity ketobemidone has a higher analgesic potency than morphine by systemic administration. It is probably due to its higher lipophilicity and consequently more easy penetration into the CNS. Ketobemidone is indicated for the treatment of all types of severe pain, such as postoperative, cancer, kidney stones and fractures.

Sample Use Guides

In Vivo Use Guide
Curator's Comment: The most commonly cited equalisation ratio for analgesic doses is 25 mg of ketobemidone hydrobromide to 60 mg of morphine hydrochloride or sulfate and circa 8 mg of ketobemidone by injection. https://www.drugbank.ca/drugs/DB06738
Oral Light 5mg Common 5-10mg Strong 10-15mg.
Route of Administration: Oral
In Vitro Use Guide
Curator's Comment: Affinities of ketobemidone and morphine for Mu, Delta and Kappa opioid receptors in bovine caudate nucleus were determined.
The affinity of ketobemidone to the mu-receptor is significantly lower than that of morphine considering Ki values of 5.5 and 2.4 nM respectively. At the delta-binding site the two opioids have equal affinity (Ki values 143 versus 136 nM), whereas ketobemidone has much lower affinity than morphine to the kappa-receptor (Ki 599 versus 130 nM).
