BACKGROUND: Mefenamic acid (MFA), a common analgesic, causes central nervous system (CNS) toxicity at high doses with a proposed activity on the Gamma-aminobutyric acid (GABA) system. However, it remains unknown whether flumazenil (FMZ), a GABA type A receptor (GABAAR) antagonist, can reverse MFA toxicity. METHODS: The behavioral and neurophysiological effects of MFA were investigated in mice with and without FMZ pre-treatment. The elevated zero maze (EZM) and marble burying tests were used to assess anxiety-like behaviors and burying activities, respectively...

Cytochrome P450 4A11 (CYP4A11) has many endogenous and exogenous compounds containing a carboxyl group in their structure as substrates. If drugs with this characteristic potently attenuate the catalytic function of CYP4A11, drug-drug interactions may occur. Acidic non-steroidal anti-inflammatory drugs (NSAIDs) possess a carboxylic acid in their structure. However, it remains unclear whether these drugs inhibit CYP4A11 activity. The present study examined the inhibitory effects of acidic NSAIDs on CYP4A11 activity using human liver microsomes (HLMs) and recombinant CYP4A11...
