Significance of Metabolism of drug
Drug metabolism, a crucial process affecting drug bioavailability, occurs differently across species. While the nose offers limited metabolic activity, it still poses a significant barrier to nasal drug delivery. Topical applications bypass first-pass metabolism in the liver, a key advantage in drug administration. Understanding these variations is vital for effective drug development and delivery strategies.

The concept of Metabolism of drug in scientific sources
Drug metabolism, bypassed by topical preparations avoiding liver processing, significantly impacts bioavailability in nasal dosages despite the nose's low metabolic environment, and varies considerably across animal species.

(1) Although nose provides low metabolic environment, this in nasal cavity is considered as a major barrier for bioavailability of nasal dosage forms.[1] (2) Topical preparation avoids this in the liver, according to the text.[2]
