慢性疾患の蔓延とドラッグデリバリーシステムに対する需要の高まりが、低分子注射薬市場に拍車をかけています。低分子医薬品は、生物製剤やバイオシミラーに比べて分子量が小さく、化学的・物理的性質が異なります。静脈注射、筋肉注射、皮下注射など、さまざまな経路で投与することができます。従来の注射剤と比較した場合の低分子注射薬の利点としては、薬物の放出制御、安定性の向上、バイオアベイラビリティの向上などが挙げられます。低分子注射薬の様々な治療用途には、がん、感染症、自己免疫疾患、心血管疾患などが含まれます。さらに、ドラッグデリバリー技術の進歩、特に難溶性薬剤や自己投与可能なデバイスの進歩が、この市場の範囲をさらに拡大しています。

市場力学：

低分子注射薬の世界市場は、様々な慢性疾患や生命を脅かす疾患の罹患率の増加、そのような疾患に罹患しやすい高齢者人口の増加、特定の治療における経口薬よりも注射薬への嗜好の高まりによって牽引されています。しかし、注射薬の承認に関する厳しい規制政策やプロセス、研究開発や臨床試験に関連する高コスト、注射による薬物投与に関連する安全性の問題などは、市場成長を抑制する要因の一部です。市場参入企業は、先進的で標的を絞ったドラッグデリバリーシステムを提供し、注射薬の選択肢が限られている治療法のための製剤を開発し、患者数の多い新興国経済に注力する機会があります。
