Transdermal spray
Device to a place a drug onto the skin
From Wikipedia, the free encyclopedia
A metered-dose transdermal spray delivers a drug to the skin surface for subsequent transdermal absorption. It functions similarly to other transdermal dosage forms such as patches and gels.[1]
In metered-dose transdermal sprays, a volatile solvent system rapidly dries after application, leaving the drug concentrated in or on the stratum corneum as a reservoir or depot from which it is released over time.[2]
An example of an approved transdermal spray is Evamist (estradiol transdermal spray), indicated for the treatment of moderate to severe vasomotor symptoms due to menopause.[3]
