Affected person-Particular Elements
Affected person-specific components, akin to genetic polymorphisms, dietary standing, and concurrent diseases, may affect the time it takes for fluconazole to work. A research printed within the Journal of Pharmacogenetics and Genomics discovered that genetic polymorphisms within the CYP2C9 and CYP3A4 genes affected fluconazole metabolism and clearance.
“Genetic polymorphisms can have an effect on fluconazole metabolism and clearance.”
(6)
Dietary standing may impression fluconazole absorption and bioavailability. A research printed within the Journal of Medical Pharmacology discovered that sufferers with malnutrition skilled decreased fluconazole absorption and bioavailability in comparison with well-nourished sufferers.
