摘要:
Mast cell degranulation inhibitors having a carboxyl group have not been used as medicines for external application, because of their low transdermal permeatibility. If the inhibitors are administered through transdermal application, any adverse side effect on organs in the body which may be produced when administered via an oral route administration could be avoided. Further, some of the mast cell degranulation inhibitors have an extremely poor photostability. This contributes to the difficulty in the development of a medicine for external application comprising the inhibitor. The transdermal permeability and photostability of a mast cell degranulation inhibitor can be improved by using the inhibitor in the form of a salt with an organic amine. Thus, disclosed is a preparation for external application comprising a mast cell degranulation inhibitor. The mast cell degranulation inhibitor and a preparation comprising the mast cell degranulation inhibitor can be improved in photostability.
摘要:
An anti-inflammatory analgesic for external use containing etodolac as NSAID, which is excellent not only in skin permeability but also in the penetration into tissues present in the portions deeper than the skin and the diffusion in the tissues and which can act directly on the muscles or joint tissues with inflammation or pain and is little irritant to the skin, more specifically, an anti-inflammatory analgesic characterized by containing etodolac and a local anesthetic.

A jelly preparation containing biguanide medicine that at administration, suppresses bitterness and harsh taste and reduces discomfort, and that despite having stability, excels in medicine release in the gastrointestinal tract. There is provided a jelly preparation containing biguanide medicine characterized in that a biguanide medicine, an inorganic acid and a water soluble polymer are contained. By virtue of the particular action of the inorganic acid, the conflicting properties of excelling in jelly preparation stability and medicine release can be simultaneously realized.

It is intended to provide a liquid matrix for medicinal use in which a drug can be easily solubilized, dispersed or suspended and which can be easily swallowed because of being a liquid, has favorable working properties in sterilization and so on and a high stability, also exhibits an effect of masking bitterness, and gels in vivo so as to control the release speed, and liquid oral preparations using the same. Namely, a liquid matrix which is a liquid auxiliary facilitating the swallowing of a drug, characterized by containing a water-soluble polymer gelling under acidic conditions and the break stress of the gel being about 3.0x103 N/m2 or more. Liquid oral preparations having favorable slow release properties even though being a liquid.

The present invention provides a transdermal absorptive liquid preparation in which a medicament or a salt thereof is colloidally dispersed in propylene glycol or a propylene glycol-containing solvent, whose transdermal permeability of the medicament is excellent, problem of skin irritation is reduced. The liquid formulation of the present invention has a mode of particle diameter at around 100nm, and an average particle size of 50 to 500 nm. The liquid formulation of the present invention makes marked improvement in the transdermal permeability by further containing an absorption promoter such as triethanolamine.
摘要:
It is intended to provide an external medicine for wounds which has nonconventional convenience in treating skin damages accompanied by a large amount of an exudation such as bedsore, skin ulcer and burn and yet has such advantages as observed in conventional medicines having been employed in treating these wounds. The external medicine for wounds is characterized by containing a water-soluble polymer and a crosslinking agent and being in the form of a powder or an ointment. After absorbing an exudation, the medicine undergoes phase transition from a sol to a gel and thus exhibits effects of adsorbing and eliminating necrotic tissues and protecting the wound face. Subsequently, it can continuously absorb the exudation. After using, it can be easily separated substantially as a mass, thereby achieving high therapeutic effects and convenience.
