Product Overview

Product Description

Aminophylline / Arginine Description^1-5

Compounded Aminophylline / Arginine Gel is a topical formulation intended to support female sexual arousal and genital sensitivity. It contains two active ingredients: aminophylline, a phosphodiesterase inhibitor, and L-arginine, a precursor to nitric oxide. This combination may help improve blood flow to the genital tissues. The gel is typically applied to the vulvar or clitoral area before sexual activity to promote arousal, enhance lubrication, and support orgasmic response in women experiencing Female Sexual Arousal Disorder (FSAD) or other sexual dysfunctions.

Product Mechanism of Action

Mechanism of Action^1-5

Aminophylline

A complex of theophylline and ethylenediamine.
Inhibits phosphodiesterase (PDE), leading to increased intracellular cyclic AMP (cAMP) levels.
Elevated cAMP promotes smooth muscle relaxation and vasodilation, improving blood flow to applied areas.
Has mild lipolytic properties, though this effect is more relevant in cosmetic applications.

L-Arginine

A naturally occurring amino acid and precursor to nitric oxide (NO).
Nitric oxide may act as a vasodilator, increasing blood flow by relaxing vascular smooth muscle.
May enhance blood flow, which can increase clitoral and vulvar engorgement, contributing to improved sensitivity and sexual pleasure.

Combined Effect

The combination of aminophylline and L-arginine may synergistically enhance genital blood flow, improving sexual responsiveness and local tissue sensitivity in women.

Product Adverse Reactions

Common (local)^1-5
