DRUG INTERACTIONS-
Androgen deprivation therapy (ADT) and other therapies targeting the androgen pathway, such as androgen receptor antagonists, can result in changes in uptake of flotufolastat F 18 in prostate cancer.
The effect of these therapies on performance of POSLUMA PET has not been established.
Indication:
U.S. FDA APPROVED DRUGS DURING 2023
Sr.No- 21
Adverse Reaction:
ADVERSE REACTIONS-
The most common adverse reactions (=0.4%) are diarrhea, blood pressure increase, and injection site pain.
Contra-Indications:
CONTRAINDICATIONS-
None.
WARNINGS AND PRECAUTIONS-
• Risk of Image Misinterpretation: Image interpretation errors can occur with POSLUMA imaging. Interpretation of POSLUMA PET may differ depending on imaging readers in patients with suspected recurrence of prostate cancer. Consider multidisciplinary consultation and histopathological confirmation.
• Radiation risk: POSLUMA contributes to a patient’s long-term cumulative radiation exposure. Ensure safe handling to protect patients and health care workers from unintentional radiation exposure.
Dosages/ Overdosage Etc:
DOSAGE AND ADMINISTRATION-
• Recommended amount of radioactivity of POSLUMA is 296 MBq (8 mCi) administered as an intravenous bolus injection.
• Initiate imaging approximately 60 minutes after administration. Scanning should start from mid-thigh and proceed to base of skull.
• See full prescribing information for additional preparation, handling, administration, imaging, and radiation dosimetry information.
DOSAGE FORMS AND STRENGTHS--
Injection: 296 MBq/mL to 5,846 MBq/mL (8 mCi/mL to 158 mCi/mL) as flotufolastat F 18 gallium in approximately 25 mL at end of synthesis in a multiple-dose vial.
Patient Information:
PATIENT COUNSELING INFORMATION
Adequate Hydration Instruct patients to drink a sufficient amount of water to ensure adequate hydration before their PET study and urge them to drink and urinate as often as possible during the first hours following the administration of POSLUMA, in order to reduce radiation exposure

Pharmacology/ Pharmacokinetics:
CLINICAL PHARMACOLOGY
1. Mechanism of action-
Flotufolastat F 18 binds to PSMA (IC50 = 4.4 nM) expressed on cells, including prostate cancer cells, and is internalized.
Prostate cancer cells usually overexpress PSMA. Fluorine-18 is a ß+ emitting radionuclide that can be detected using positron emission tomography.
2. Pharmacodynamics -
The relationship between flotufolastat F 18 plasma concentrations and image interpretation has not been fully characterized.
3. Pharmacokinetics-
Distribution -
Following intravenous administration, flotufolastat F 18 distributes to liver (15.8% of administered activity), heart blood pool (7.4%), and kidneys (3.2%) and is cleared from the blood.
Elimination Metabolism Flotufolastat F 18 does not undergo metabolism up to 50 minutes post injection.
Excretion Elimination is by urinary excretion. Approximately 7% of the administered activity was excreted in the urine in the first 2 hours post-injection with approximately 15% excreted by 4.5 hours post-injection.
Pregnancy and lactation:
USE IN SPECIFIC POPULATIONS-
1. Pregnancy Risk Summary-
POSLUMA is not indicated for use in females. There are no available data on the use of POSLUMA in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes.
Animal reproduction studies have not been conducted with flotufolastat F 18. Radioactive drugs, including POSLUMA, have the potential to cause fetal harm depending on the fetal stage of development and the magnitude of the radiation dose.
2. Lactation Risk Summary-
POSLUMA is not indicated for use in females. There are no data on the presence of flotufolastat F 18 in human milk, the effect on the breastfed infant, or the effect on milk production.
3.Pediatric Use-
The safety and effectiveness of POSLUMA have not been established in pediatric patients.
5. Geriatric Use-
Among the total number of patients receiving POSLUMA in clinical studies of prostate cancer, 463 (62%) were 65 years of age and older, while 118 (16%) were 75 years of age and older.
No overall differences in safety or effectiveness were observed between these patients and younger adult patients.
OVERDOSAGE-
In the event of an overdose of POSLUMA, maintain hydration of the patient and frequent voiding to minimize radiation exposure.
A diuretic might also be considered. If possible, an estimate of the radiation effective dose administered to the patient should be made.
