Flutemetamol (18F) API Manufacturers

General Description:

Flutemetamol (18F), identified by CAS number 765922-62-1, is a notable compound with significant therapeutic applications. Flutemetamol (18F) is a PET scanning radiopharmaceutical containing the radionuclide fluorine-18. It is indicated for Positron Emission Tomography (PET) imaging of the brain to estimate β amyloid neuritic plaque density in adult patients with cognitive impairment who are being evaluated for Alzheimer's disease (AD) or other causes of cognitive decline.

Indications:

This drug is primarily indicated for: Flutemetamol F18 is indicated for Positron Emission Tomography (PET) imaging of the brain to estimate β amyloid neuritic plaque density in adult patients with cognitive impairment who are being evaluated for Alzheimer's disease (AD) or other causes of cognitive decline. Its use in specific medical scenarios underscores its importance in the therapeutic landscape.

Metabolism:

Flutemetamol (18F) undergoes metabolic processing primarily in: The F 18 in circulation during the 30-120 minutes imaging window in plasma was principally associated with flutemetamol metabolites. This metabolic pathway ensures efficient processing of the drug, helping to minimize potential toxicity and side effects.

Absorption:

The absorption characteristics of Flutemetamol (18F) are crucial for its therapeutic efficacy: The time-activity curves for flutemetamol F 18 in the brain of subjects with positive scans shows continual signal increases from time zero through 30 minutes post administration, with stable values thereafter up to at least 120 minutes post-injection. Following intravenous injection of 185 MBq (5 mCi) of Vizamyl in humans, flutemetamol F 18 plasma concentrations declined by approximately 75% in the first 20 minutes post-injection, and by approximately 90% in the first 180 minutes. The drug's ability to rapidly penetrate into cells ensures quick onset of action.

Route of Elimination:

The elimination of Flutemetamol (18F) from the body primarily occurs through: Excretion was found to be approximately 37% renal and 52% hepatobiliary. Understanding this pathway is essential for assessing potential drug accumulation and toxicity risks.

Pharmacodynamics:

Flutemetamol (18F) exerts its therapeutic effects through: Following intravenous injection, flutemetamol F 18 diffuses across the human blood-brain barrier and produces a radioactivity signal detectable throughout the brain. Subsequently, cerebral perfusion decreases the brain flutemetamol F 18 content, with differential retention of the drug in cortical areas that contain β-amyloid aggregates compared to areas that lack the aggregates. The drug's ability to modulate various physiological processes underscores its efficacy in treating specific conditions.

Mechanism of Action:

Flutemetamol (18F) functions by: Fluorine-18 (F 18) is a cyclotron-produced radionuclide that decays by positron emission (β+ decay, 96.7%) and orbital electron capture (3.3%) to stable oxygen-18 with a physical half-life of 109.8 minutes. The positron can undergo annihilation with an electron to produce two gamma rays; the energy of each gamma ray is 511 keV. After flumetamol F18 is given intravenously, it accumulates in beta amyloid plaques in the brain, and thus becomes visible via positron emission tomography (PET). This mechanism highlights the drug's role in inhibiting or promoting specific biological pathways, contributing to its therapeutic effects.

Toxicity:

Classification:

Flutemetamol (18F) belongs to the class of organic compounds known as benzothiazoles.
