A patch (10) comprising: a nonwoven fabric (1); and an adhesive layer (2) on the nonwoven fabric (1), wherein the adhesive layer (2) comprises a cool feeling agent, a local anesthetic and/or an anti-inflammatory analgesic, and water, and the adhesive layer (2) has a maximum thickness of 0.50 mm or more.

Intravesical drug delivery devices that include a device body, a number of solid drug tablets, and a retention frame. The device body includes a drug reservoir lumen and a retention frame lumen. The drug tablets is positioned in the drug reservoir lumen, and the retention frame is positioned in the retention frame lumen.

A polymeric bio-adhesive film forming topical spray formulation providing a modified, pulsatile (e.g., biphasic) release of the active agent(s) once the solvent evaporates and the film sets, e.g., on human skin is disclosed. In certain embodiments, the active agent is bupivacaine hydrochloride.

A quaternary ammonium salt compound of formula I is fast-acting and has a long-term local anaesthetic effect after a single administration, the sensory nerve block time being longer than the motor nerve block time, has both a long-acting local anaesthetic effect and a selective local anaesthetic effect, and also significantly reduces the side effects of quaternary ammonium salt compounds with the structural features of surfactants and is highly safe; thus, the compound of formula I and the pharmaceutically acceptable salt thereof can be used for the preparation of saft drugs having a long-term local anaesthetic effect and a selective local anaesthetic effect
