Definitions
- the present invention relates to a transdermal preparation containing testosterone which is excellent in skin permeability of testosterone and excellent in pharmaceutical properties.
- Testosterone is a male hormone (androgen) produced in the testis. Androgens are responsible for many important physiological functions, affecting muscles, bones, central nervous system, prostate, bone marrow, sexual function and so on. Diseases or symptoms due to age-related decline in testosterone concentration in addition to sexual dysfunction due to congenital or acquired testosterone deficiency, such as male menopausal disorder, metabolic syndrome, diabetes, insulin resistance, obesity, arteriosclerosis, osteoporosis, Testosterone replacement therapy is performed with injections, gels and reservoir-type preparations as treatments for muscle weakness, cognitive decline, memory impairment, and depression. However, in addition to the need for frequent visits, injections have difficulty maintaining physiological blood levels, and in the case of gels, the difficulty of accurately administering, and administration to the skin Issues such as secondary exposure to others of the
- the drug in the case of patch preparations, particularly matrix type transdermal preparations, the drug can be stably administered at a constant dose, and administration of the desired drug and interruption of administration can be performed simply by simple operations such as sticking and peeling. Or there is little possibility of contamination to others as it can be discontinued.
- matrix-type transdermally-administered preparations containing testosterone patches using a base such as an acrylic pressure-sensitive adhesive have been conventionally studied [Patent Document 1 and Patent Document 2].
- pressure-sensitive adhesives such as acrylic pressure-sensitive adhesives, rubber-based pressure-sensitive adhesives, or silicon-based pressure-sensitive adhesives have low drug release properties from the preparation, and therefore, when trying to enhance drug release properties, In addition, it is necessary to mix a large amount of a drug absorption enhancer, and as a result, there is a problem that the physical properties of the preparation are deteriorated.
- non-aqueous patches containing a water-soluble polymer such as polyacrylic acid as a main base and compounded with various drugs have been studied [Patent Document 3].
- a hydrophilic solvent such as a polyhydric alcohol can be blended in relatively large amounts, so It is considered to be suitable for incorporating relatively soluble drugs into sexual solvents.
- the absorption enhancer is generally an oily solvent, so the solvent itself separates from the preparation and the oily solvent exudes from the preparation, As a result, there is a problem that the physical properties of the preparation are impaired, such as the decrease in adhesive strength.
- a surfactant is added to the preparation in order to suppress the exudation of an oily solvent from the preparation, the influence thereof causes undesirable effects such as skin irritation.
- lactic acid ester is excellent as a testosterone absorption promoter [Patent Document 4].

製造後3日目における各実施例および各比較例の剥離ライナーを剥離し、剥離後のフィルムに付着していた液状成分の量を目視確認することにより、膏体物性を評価することで製剤物性を評価した。その結果を前記表1~表3に示す。なお、本試験の評価基準は以下の通りである。
〔物性評価基準〕
○:剥離ライナーには液状成分は付着していなかった。
△:ごく微量の液状成分が剥離ライナーに付着していた。
×:剥離ライナーのほぼ全面に液状成分が付着していた。
本発明の経皮投与製剤におけるテストステロンの経皮吸収性を検討するため、各実施例、ならびに比較例1、2、4および5の製剤について、ヘアレスラットにおけるインビトロ皮膚透過性試験を行った。雄性ヘアレスラット(HWY系、7週齢)の腹部摘出皮膚をフランツ型拡散セルにセットし、円形(φ28mm)に裁断した各試験製剤を貼付した。レセプター側には40%ポリエチレングリコールを溶解したリン酸緩衝生理食塩水を満たし、ウォータージャケットには、37℃の温水を還流した。経時的にレセプター液をサンプリングし、皮膚を透過したテストステロン量を液体クロマトグラフ法により測定し、その結果より、試験開始24時間後の累積透過量を算出した。その結果を、表4に示す。
上記の各試験結果より、各実施例の経皮投与製剤はテストステロンの経皮吸収性と製剤物性ともに優れた製剤であることが判明した。一方、乳酸エステルが含有されていない比較例1、ならびにアクリル系粘着剤を主基剤とした比較例4および比較例5は実施例の製剤と比較してテストステロンの経皮吸収性が大きく劣っていた。また、プロピレングリコールを配合していない比較例2および比較例3の製剤は、膏体表面からの液状成分の染み出しが見られ、製剤物性の低下が顕著であった。
