A support film for a tape material, includes a film-shaped support formed of polyurethane; and a barrier layer containing an aromatic isocyanate-based polyurethane and a layered inorganic compound and formed on one surface of the support.

Support film for tape material, and tape material

The present invention provides a topical preparation for treating hyperhidrosis, comprising water, an anticholinergic drug, and one or more salts selected from the group consisting of lactate, tartrate, acetate and phosphate. Such a topical preparation comprises the above certain salt, thereby facilitating the accumulation of the anticholinergic drug in skin appendages.

External agent for treating hyperhidrosis

A support film for tape which is used for a tape includes a film-shaped support formed of polyurethane, a barrier layer which includes polyvinyl alcohol and a layered inorganic compound and is formed on a surface of the support, and an undercoat layer which is disposed between the support and the barrier layer, and which causes the support and the barrier layer to adhere to each other.

Support film for tape and tape

By providing a non-liquid drug reservoir layerhaving first and second principal surfaces and containing a drug and a polymer that is to be a base, a drug permeation layerdisposed at the first principal surface side of the drug reservoir layerand being lower in permeability of the drug than the drug reservoir layer, and a first backingwith a bending resistance of 10 to 80 mm that is formed so as to cover a side surface of the drug reservoir layer, skin irritation can be reduced.

Transdermal preparation

Provided is a transdermal preparation, which is capable of long-term (1-day to 7-day) release of a basic drug from a preparation, continuously and at a consistent concentration; shows little reduction over time in the drug content, even if multiple drugs are contained in the preparation; and is produced by a simple process. The transdermal preparation comprises a substrate, and an adhesive layer containing a basic drug and a water-soluble polymer.
