PROPAFENONE.

Avoid CAS 54063-53-5

Propafenone is an FDA-approved prescription antiarrhythmic medication primarily utilized for treating serious, potentially life-threatening irregular heartbeats. Its application is strictly confined to medical settings for conditions such as atrial fibrillation and ventricular arrhythmias, with no established use or data for cosmetic purposes.

Summary

Science

Mechanism of Action

Propafenone acts as a Class 1C antiarrhythmic by blocking sodium channels, which are crucial for the heart's electrical activity. This action modulates abnormal cardiac rhythms. It also exhibits a minor local anesthetic effect and weak beta-blocking properties. Crucially, there is no researched or established mechanism of action for propafenone on the skin.

Dusting Analysis

Not commonly dusted

Propafenone is a potent prescription medication with no recognized cosmetic applications; therefore, the concept of 'dusting' (using sub-efficacious concentrations in skincare for marketing claims) does not apply to this ingredient in a cosmetic context.

Stability

Propafenone hydrochloride is slightly soluble in water, chloroform, and ethanol, and sparingly soluble in aqueous buffers; for maximum aqueous solubility, initial dissolution in DMSO may be required before dilution. Tablets and extended-release capsules should be stored at room temperature (20-25°C), with immediate-release tablets requiring light-resistant containers.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

Propafenone is an FDA-approved prescription drug with a boxed warning, indicating its use is restricted to life-threatening heart rhythm disorders due to increased mortality risk, particularly in patients with structural heart disease. Oral administration can lead to severe side effects including allergic reactions such as hives, respiratory difficulties, angioedema, and skin rash. There is no safety data available for its topical application in cosmetic formulations, and given its systemic risks, it is highly unsuitable for such use.
