propellant

(prŏ-pĕl′ănt) [L. propellere, to drive forward]
Any agent that forces another to move in a desired direction. Inhaled medications rely on propellants to improve drug delivery to patients. Hydrofluoroalkane propellants are used in metered dose inhalers, i.e., in canisters that deliver drugs such as beta-agonists or anticholinergic agents to patients with asthma or chronic obstructive lung disease.
