A comparison of family physician and dermatologist topical corticosteroid prescriptions: A population-based cross-sectional study
2023, Journal of the American Academy of DermatologyOptimizing topical management of atopic dermatitis: Is it time for advancement to a systemic medication?
2022, Annals of Allergy, Asthma and ImmunologyCitation Excerpt :The National Eczema Association website (www.nationaleczema.org) provides tips toward proper use, including the use of “fingertip units (FTU)” for different body sites on the basis of age. For example, 1 FTU (approximately 0.4 g for adult women and 0.5g for adult men, defined as the amount of ointment or cream squeezed from a tube from the tip of an adult index finger to the first finger crease) suffices for the face and neck of a 4-month-old, but 2.5 FTUs would be necessary to cover the same area in an affected patient aged 10 years or older.31 Prescribing an insufficient amount will also compromise treatment results.
Development and validation of the fingertip unit for assessing Facial Vitiligo Area Scoring Index
2022, Journal of the American Academy of DermatologyCitation Excerpt :It is of less utility when evaluating skin lesions smaller than the size of the palm, however, especially in the case of vitiligo. The fingertip unit (FTU) in dermatology has been conventionally used as a tool to explain an appropriate amount of topical medication to be applied to prevent the patients from using excessive amount of topical steroid.12 In this study, we devised the FTU, conceptualized as the area between the joints of the phalanges, as a measurement unit to assess the extent of facial vitiligo more precisely.
Potential of biocompatible polymeric ultra-thin films, nanosheets, as topical and transdermal drug delivery devices
2019, International Journal of PharmaceuticsCitation Excerpt :When the nanosheet without BV was used as a controlled-release membrane, the nanosheet was first applied to a silicon membrane and nanosheet formulation was piled on it. A fingertip unit (1.90 µg/cm2) of commercial ointment was applied onto a silicone membrane that had previously set in a diffusion cell (Finlay et al., 1989). Immediately after applying the formulation, 6.0 mL of 40% (v/v) ethanol-water solution was added to the receiver chamber to initiate the BV-release experiment.
Common dermatologic conditions
2014, Medical Clinics of North AmericaCitation Excerpt :The concept of the fingertip unit (FTU) of topical medication (a single line of cream or ointment from a standard tube that extends along the distal phalanx of the patient’s index finger) can be useful in advising how much to apply. A single FTU is enough for one hand, 2 FTU enough for a foot, 3 FTU for an arm, and 6 FTU for a leg.83,84 Corticosteroids are among the most commonly prescribed class of topical medications.
