Edotreotide Gallium Ga-68
Edotreotide Gallium Ga-68 Uses, Dosage, Side Effects, Food Interaction and all others data.
Edotreotide Gallium Ga-68 is an 8 amino acid peptide bound to the chelator 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA). Edotreotide Gallium Ga-68 is indicated for localizing somatostatin receptor positive neuroendocrine tumors by positron emission tomography. Dotatate gallium Ga-68 is used for a similar indication. Dotatate gallium Ga-68 has lower tumor uptake but this data is highly variable between patients.
Edotreotide Gallium Ga-68 was granted FDA approval on 21 August 2019.
Edotreotide Gallium Ga-68 binds to somatostatin receptors where it emits beta particle radiation for detection by positron emission tomography. The duration of action is short as it has short radioactive and biological half lives. Patients should hydrate before and after the administration of this medication to encourage frequent urination and rapid clearance.

Uses
Edotreotide Gallium Ga-68 is a radioactive diagnostic agent used in PET scans for somatostatin receptor positive neuroendocrine tumors in adult and pediatric patients.
Edotreotide Gallium Ga-68 is a radioactive diagnostic compound used in positron emission tomography (PET) for diagnose somatostatin receptor positive neuroendocrine tumors in pediatrics and adults.
Edotreotide Gallium Ga-68 is also used to associated treatment for these conditions: Neuroendocrine Tumors
How Edotreotide Gallium Ga-68 works
Edotreotide Gallium Ga-68 binds to somatostatin receptors, with higher affinity for somatostatin receptor type 2, where it emits beta particle radiation for detection by positron emission tomography (PET).
Toxicity
The LD50 of this medication is not readily available.
In the event of an overdose, give patients plenty of fluids and diuretics if necessary to encourage frequent urination. If possible, an estimation of radioactive dose should be performed.
Food Interaction
No interactions found.Volume of Distribution
Data regarding the volume of distribution of this medication is not readily available.
Elimination Route
Edotreotide Gallium Ga-68 reaches 80% activity in tumors within 30 minutes, and reaches its highest activity in tumors 70±20min post injection. Edotreotide is mostly taken up into the spleen, followed by kidneys, liver, pituitary, thyroid, and adrenal gland. Accumulation in non-tumor tissue reaches a maximum within 40 minutes.
Half Life
Edotreotide Gallium Ga-68 has a radioactive half life of 68 minutes. Edotreotide Gallium Ga-68 has two half lives, 2.0±0.3min and 48±7min for its removal from blood.
Clearance
Data regarding the clearance of this medication is not readily available.
Elimination Route
16% of a Edotreotide Gallium Ga-68 dose is eliminated in the urine within 2h. It is expected that Edotreotide Gallium Ga-68 is exclusively eliminated in the urine. In animal studies, edotreotide Y-90 was >80% eliminated in the urine within 24h, with 95.6±3.4% being unmetabolized. 5
