Note: Monitor patients with diabetes mellitus and optimize antidiabetic therapy prior to initiating therapy. Treat the patients with hypokalemia and hypomagnesemia before starting the therapy.
Initial IM dose:
40
mg
once every 4 weeks (dose can be adjusted according to levels of growth hormone to 60 mg once every 4 weeks after >3 months if levels are normalized. Decrease the dose to 20 mg if adverse effects occur.)
Do not administer missed dose 2 weeks prior to the next dose.
Initial SC:
0.6 - 0.9
mg
twice a day
Dose adjustment: Increase the dose in increments of 0.3 mg twice a day every 3 months depending on the normalization of urinary-free cortisol levels
Decrease the dose by 0.3 mg if an adverse reaction occurs
Maintenance dose SC: 0.3 to 0.9 mg twice a day
Initial IM: 10 mg once every 4 weeks
Dose adjustment: Monitor for 24-hour UFC levels, if not normalized increase the dose maximum up to 40 mg once every 4 weeks
Discontinue the therapy if adverse reactions occur
Do not administer missed dose 2 weeks prior to the next dose
Dose Adjustments
For Hepatotoxicity:
Moderate hepatotoxicity for IM dose: Initially 20 mg once every 4 weeks and maintain not more than 40 mg once every 4 weeks

Severe hepatic impairment for SC dose: Discontinue temporarily
when both drugs are combined, there may be an increased risk or severity of QTC prolongation
QTc interval is increased both by lenvatinib and pasireotide
when both drugs are combined may enhance the bradycardia effect and raise blood pressure

when both drugs are combined may enhance the bradycardia effect and raise blood pressure
It may diminish the effects when combined with copper CU 64 dotatate by the receptor binding mechanism
pasireotide exerts its influence on gallium ga 68 dotatate by engaging in receptor binding competition, thereby diminishing its effects
