Cannabinoids and drug–drug pharmacokinetic interactions: Deciphering the risks

British Journal of Clinical Pharmacology, Volume 92, Issue 5, Page 1287-1308, May 2026.
The relationship between cannabinoids and mental health has become a major focus of scientific inquiry and public discourse. Cannabinoids are diverse chemical compounds from the Cannabis species that have been explored for their therapeutic applications in treating chronic pain, psychiatric and neurological conditions, such as depression, schizophrenia,

In Vitro and Clinical Evaluation of Potential Interactions of Bemnifosbuvir with Drug‐Metabolizing Enzymes

The Journal of Clinical Pharmacology, Volume 66, Issue 5, May 2026.
Abstract Bemnifosbuvir is a novel oral guanosine nucleotide prodrug with potent pan‐genotypic inhibitory activity against hepatitis C virus. In vitro studies assessing the inhibition or induction potential of bemnifosbuvir on the CYP450 and UGT1A1 enzymes demonstrated that bemnifosbuvir is a weak inducer and a reversible and time‐dependent inhibitor of

Phenacetin N-deacetylase and its non-identity with the serotonin sensitive aryl acylamidase of brain

, 1980
Phenacetin N-deacetylase was characterized in monkey brain. The enzyme needed Triton X-100 for maximal extraction and it had a high specific activity in cerebellum and in the nuclear fraction of whole monkey brain.

Comparative Protective Effects of N-Acetylcysteine, N-Acetyl Methionine, and N-Acetyl Glucosamine against Paracetamol and Phenacetin Therapeutic Doses–Induced Hepatotoxicity in Rats

International Journal of Hepatology, 2018
Background and Aims. Both paracetamol (PA) and phenacetin (PH) are analgesic and antipyretic agents. Part of phenacetin therapeutic activity is attributed to its metabolism into paracetamol. Paracetamol causes direct hepatic oxidative stress damage.

In vivo effect of diallyl sulfide and cimetidine on phenacetin metabolism and bioavailability in rat. [PDF]

, 2002
Numerous cytochrome P450 inhibitors have been described as effective modulators of cytochrome P450 isoforms activity in vitro. Their inhibitory efficiency may be considerably modified after in vivo application.

Phenacetin acts as a weak genotoxic compound preferentially in the kidney of DNA repair deficient Xpa mice.

, 2006
Chronic use of phenacetin-containing analgesics has been associated with the development of renal cancer. To establish genotoxicity as a possible cause for the carcinogenic effect of phenacetin, we exposed wild type and DNA repair deficient Xpa-/- and ...

Antiplasmodial Activity and Pharmacokinetic Profiling of Cryptolepine and 2,7‐Dibromocryptolepine With a View to Informing the Design of Novel Antimalarial Cryptolepine Analogues

Drug Development Research, Volume 87, Issue 2, April 2026.
ABSTRACT The roots of the climbing shrub Cryptolepis sanguinolenta are traditionally used in West Africa for the treatment of malaria. The principal constituent, cryptolepine (1), has been shown to have antimalarial activity but there are concerns regarding its toxicity on account of its DNA‐intercalating property.

The Effect of Acetylsalicylic Acid, Caffeine, and Codeine on the Excretion of Phenacetin Metabolites

, 1972
The urinary excretion of total N-acetyl-p-aminophenol and conjugates (NAPA) and total 2-hydroxyphenetidin and conjugates (2-OHP) was studied after ingestion of 2 g phenacetin alone and also in combination with acetylsalicylic acid, caffeine, and codeine

Metabolism of six CYP probe substrates in fetal hepatocytes

ADMET and DMPK, 2016
Cytochrome P-450 (CYP) are the most common drug metabolizing enzymes and are abundantly expressed in liver apart from kidney, lungs, intestine, brain etc. Their expression levels change with physiological conditions and disease states.
