Direct Nasal Cavity Introduction
SPONTAN® (vardenafil HCL nasal spray) is administered directly into the nasal cavity.
Rich Vascular Network
The nasal mucosa is highly vascular, ensuring rapid and efficient drug absorption.
Avoidance of First-Pass Metabolism
Unlike oral medications that undergo liver metabolism (first-pass), intranasal delivery bypasses this step, leading to a more immediate and potent drug effect.
Uniform Distribution
The nasal spray formulation ensures a uniform distribution of the drug across the nasal mucosa, leading to consistent dosing and therapeutic effect.
