Why does a lipophilic drug, like diazepam, typically exhibit a larger volume of distribution compared to a hydrophilic drug, like furosemide, after intravenous administration?

💡 Explanation

Lipophilic drugs partition more readily into tissues with high lipid content because their structure favors interaction with these hydrophobic environments; therefore, the volume of distribution is higher, rather than being confined to the bloodstream like hydrophilic drugs, rather than first pass effect or renal handling.
