Abstract
Description
一方、病院では、入院患者が自ら食事がとれるようになることも退院を決定する一つの指標になっている。このため、亜鉛の補充療法は、入院期間を短縮するうえでも有効な手段である。
しかし、亜鉛は、併用薬や食物による相互作用を受けやすいため、経口的な摂取では吸収が安定せず、所期の効果が得られないという問題がある。また胃全摘やクローン病等消化管の疾患の患者や高齢者では吸収十分でないため、経口投与よりも、注射や点滴などによる非経口的な投与のほうが、一定期間内で所期の体内亜鉛濃度が得られ、またそれを安定に維持する方法として有用であると考えられる。
より詳細な課題は、使用時に生理食塩水で希釈して点滴静注した場合に生じ得る痛み(血管痛)が有意に抑制されており、しかも、生理食塩水で希釈した際に生じる得る点滴液の白濁(結晶の析出)が有意に抑制されてなる、亜鉛点滴静注用製剤を提供することである。
本発明は、かかる知見に基づいて、さらに研究を重ねて完成したものであり、下記の実施形態を包含するものである。
項2.前記亜鉛の酸付加塩が硫酸亜鉛である、項1に記載する点滴静注用製剤。
項3.亜鉛の含有量に換算して、亜鉛を1~10mg/mL濃度で含有する項1または2に記載する点滴静注用製剤。
項4.用時に、生理食塩水を用いて10倍以上に希釈して使用される、項1~3のいずれか1項に記載する点滴静注用製剤。
項5.用時に、生理食塩水を用いて希釈して亜鉛を0.5mg/mL濃度以下になるように調整して使用される、項1~4のいずれか1項に記載する点滴静注用製剤。
項6.亜鉛補充療法剤、または低亜鉛血症若しくは亜鉛欠乏症の治療剤である、項1~5のいずれか1項に記載する点滴静注用製剤。
本発明の点滴静注用製剤のpH条件によれば、亜鉛を1~10mg/mL濃度の割合で含有しながらも、少なくとも15-30℃の保存条件下で白濁化を有意に抑制することができる。また、本発明の点滴静注用製剤は、使用時に生理食塩水で希釈して、亜鉛濃度が0.5mg/mL以下になるように調整して使用することができ、こうすることで抹消血管に点滴投与した場合でも血管痛の発生が有意に抑制することができる。
なお、下記の実験は、社会医療法人近森会近森病院の院内倫理委員会審査を経て、使用許諾が得られた患者に対して実施されたものである。
硫酸亜鉛7水和物110mgを、注射用水5mLに溶解し、希硫酸でpHが5.0になるように調整し、5mL容量の滅菌ガラスアンプルに封入して、透明な点滴静注用製剤を調製した。これを、使用時に生理食塩水で全量が100mLになるように希釈して点滴液を調製した。生理食塩水で希釈した後も、白濁化(結晶の析出)は確認されなかった。
これを血中の亜鉛濃度が低下している患者10名に、1日1回100mLの静注点滴を4~7日間実施した。いずれの患者も、投与中及び投与後も血管痛を訴えることなく、投与により血中の亜鉛濃度が正常値になることが確認された。
100mL容量の有栓メスシリンダーを用いて、表1に記載する濃度になるように、硫酸亜鉛7水和物を注射用水100mLに溶解し、透明な水溶液を調製した。なお、硫酸亜鉛7水和物の量を4.4で除した値が亜鉛の量に相当する。例えば、硫酸亜鉛7水和物の含有量を亜鉛濃度に換算して、亜鉛0.5%(0.5g/100mL)の水溶液のpHは5.1であった。これに、水酸化ナトリウム水溶液をゆっくり滴下して、水溶液が白濁し始めたときのpHを測定した。水溶液中の亜鉛濃度と水溶液が白濁し始めたpHとの関係を表1及び図1に示す。なお、当該実験は、環境温度20-30℃のもと行った。pHの測定はコンパクトpH計LAQUAtowin(堀場製作所製)を使用した。
