LU AE58054 + itraconazole

LU AE58054 + itraconazole is a combination of two drugs: - **LU AE58054 (idalopirdine)** is a potent and selective antagonist of the serotonin 6 receptor (5-HT6). It was developed primarily as an adjunctive therapy for cognitive dysfunction in Alzheimer's disease and has also been studied in schizophrenia. Idalopirdine acts by blocking the 5-HT6 receptor in the brain—regions involved in cognition such as the cortex and hippocampus—modulating neurotransmitter systems to potentially improve cognitive function. It has shown efficacy as an add-on to acetylcholinesterase inhibitors like donepezil. - **Itraconazole** is a triazole antifungal agent that inhibits fungal cytochrome P450-dependent enzyme lanosterol 14α-demethylase. This inhibition disrupts ergosterol synthesis and damages fungal cell membrane integrity. The combination "LU AE58054 + itraconazole" does not represent a marketed or clinically established fixed-dose product but may refer to co-administration for drug-drug interaction studies or research purposes.
