4 Drug and Medication Information
4.1 Therapeutic Uses

In various "skin freezes" alone or with other agents by aerosol application. Recommended for spraying of snake & insect bites to retard absorption of venom. /Former/

5 Pharmacology and Biochemistry
5.1 Absorption, Distribution and Excretion

Human and animal studies indicate rapid excretion of inhaled CFC-114. In a study with radiolabeled CFC-114, 30 minute retention of the dose inhaled in a single breath was 12% versus 23%, 10%, and 20% for comparable doses of trichlorofluoromethane (CFC-11), dichlorodifluoro-methane (CFC-12), and trifluorotrichloroethane (CFC-113), respectively.

... Main factor affecting fate of fluorocarbons is body fat, where they are concentrated & slowly released into blood at concn that should not cause any risk of cardiac sensitization. /Fluorocarbons/

National Research Council. Drinking Water & Health Volume 1. Washington, DC: National Academy Press, 1977., p. 781


Abosrption of fluorocarbons is much lower after oral ingestion (35-48 times) than after inhalation. ... The lung generally has the highest fluorocarbon concentrations on autopsy. /Fluorocarbons/

Although fluorocarbons cause cardiac sensitization in certain animal species, rapid elimination prevents the development of cardiotoxic concentrations from aerosol bronchodilator use except at exceedingly high doses (12 to 24 doses in 2 minutes). /Fluorocarbons/
