Pasireotide L-aspartate salt is primarily used in the treatment of conditions related to hormonal imbalances. It is effective in managing Cushing's disease, a disorder caused by excessive cortisol production, by inhibiting the release of adrenocorticotropic hormone (ACTH) from the pituitary gland. This helps in reducing cortisol levels and alleviating symptoms such as weight gain, high blood pressure, and diabetes.

Additionally, it is utilized in the treatment of acromegaly, a condition characterized by excessive growth hormone production. By suppressing growth hormone and insulin-like growth factor-1 (IGF-1) levels, it helps control abnormal growth and related complications.

Pasireotide L-aspartate salt is also being explored for its potential in managing certain types of neuroendocrine tumors, where it may help slow tumor growth and reduce hormone-related symptoms. Its ability to target specific hormonal pathways makes it a valuable therapeutic option in these clinical settings.
