Observe Closely (1)modafinil will enhance the stage or outcome of citalopram by impacting hepatic enzyme CYP2C19 metabolism. Use Caution/Check. Citalopram 20 mg/day is the maximum proposed dose for patients using CYP2C19 inhibitors as a result of danger of QT prolongation.
Dose adjustments of such medication and other medications which have been substrates for CYP2C19 could be required if modafinil is coadministered
Also noteworthy may be the action of modafinil on other cytochromes, especially those in the cytochrome P450 procedure, which can be accountable for drug metabolism while in the liver and seems to possess a part from the brain (McFadyen et al 1998; Klose et al 1999; Voirol et al 2000; Gervasini et al 2001; Llerena et al 2003; Gervasini et al 2004). Modafinil inhibits CYP2C19, and it is a potent suppressor in hepatocytes of CYP2C9 (Robertson et al 2000), which by itself has not but been located to get existing in the brain, but other cytochrome P450 enzymes which includes CYP2C enzymes are located in the brain, and There exists evidence for a job of brain CYP 2C9 especially (Llerena et al 2003; Gervasini et al 2004). This distinct member on the cytochrome P450 relatives has been shown to generally be a functionally suitable source of reactive oxygen species in coronary artery ischemia and reperfusion personal injury, and inhibition of cytochrome P450 enzymes has been shown to reduce damage in coronary artery ischemia and reperfusion (Fleming et al 2001; Granville et al 2004).
Geriatric Use: In elderly sufferers, modafinil and metabolite elimination might be minimized, so think about using reduced doses and carefully observe patients.

mifepristone will boost the stage or influence of modafinil by influencing hepatic/intestinal enzyme CYP3A4 metabolism. Use Caution/Check.
The orexin neurons are identified completely within the lateral hypothalamus plus the orexin neurons in the hypothalamic location jobs to the whole central nervous technique [33]. Orexin neurons can be activated by modafinil. Thus modafinil may induce wakefulness by its action while in the anterior hypothalamus [34]. Nevertheless, the waking system of modafinil on orexin neurons nevertheless for being fully elucidated.
Modafinil appeared to generate a focus-linked suppression of CYP2C9 activity, as a result suggesting likely for CYP2C9 inhibition; caution if medications that have a narrow therapeutic index
Warfarin's significantly less potent R-enantiomer is metabolized in part by CYP3A4 (as well as CYP1A2 and CYP2C19). Keep an eye on INR far more usually if coadministered with inhibitors of those isoenzymes and alter warfarin dose if required.
Discontinue interfering medicine for at least five 50 percent-lives right before administration of both the dosimetry or an iobenguane dose. Don't administer these prescription drugs until eventually at the very least seven days after Just about every iobenguane dose.
Coadministration of encorafenib with sensitive CYP3A4 substrates may cause elevated toxicity or decreased efficacy of such agents.
Edgar and Seidel (1997) investigated the effects of modafinil on sleep-wake EEG and locomotor activity in Reside rats in comparison with the effects of methamphetamine. They identified that modafinil improved locomotor activity only somewhat in contrast to methamphetamine which induced profound raises in locomotor activity.
Stiripentol is really a CYP3A4 inhibitor and inducer. Keep an eye on CYP3A4 substrates coadministered with stiripentol for greater or decreased outcomes. CYP3A4 substrates may possibly have to have dosage adjustment.
