Dosage forms tackiness

Wesseling, M. Kuppler, F. Bodmeier, R. Tackiness of acrylic and cellulosic polymer films used in the coating of solid dosage forms. Eur. J. Pharm. Biopharm. 1999, 47, 73-78. 

There are a number of attributes of topical drug systems that may be classified as cosmetic that make patients more or less whHng to use their medications (comphant). These include the ease of appHcation, the feel of the preparation once it is on the skin, and the appearance of the applied film. Ideally, the appHcation should be undetectable to the eye and neither tacky nor greasy. Certain items, such as ointments and pastes, are of course intrinsically greasy, and suspensions of aU types tend to leave an opaque, easily detectable fHm. Thus, the extent to which the cosmetic features can be idealized is dependent on the nature and purpose of the dosage form.
