SUSTAINED-RELEASE INJECTABLE COMPOSITION CONTAINING DUTASTERIDE

原文（中国語）

An embodiment relates to a sustained-release injectable composition containing dutasteride, which may exhibit a sustained dutasteride release effect for 3 months or more even when the dose of dutasteride is equal to or less than that of existing AVODART®, which is taken once a day, thereby exhibiting a long-acting drug effect by a single injection. In addition, the injectable composition may exhibit a therapeutic effect on benign prostatic hyperplasia, prostate cancer, and hair loss continuously for 3 months or more, may maintain an effective concentration of the drug at a constant level by controlling the release of the drug due to the constant average diameter of the microparticles contained in the sustained-release injectable composition, and may reduce foreign body sensation and pain when administered by injection to a patient.
