Identification

Summary

Technetium Tc-99m sestamibi is a radiopharmaceutical diagnostic agent used in nuclear medicine imaging tests to detect coronary artery disease and evaluate myocardial function.

Background

Technetium Tc-99m sestamibi (commonly sestamibi) is a pharmaceutical agent used in nuclear medicine imaging. The drug is a coordination complex consisting of the radioisotope technetium-99m bound to six methoxyisobutylisonitrile (MIBI) ligands, hence the name sesta (6) MIBI.. Following intravenous injection of the drug, Technetium Tc-99m sestamibi is taken up by the myocardium, parathyroid, and/or breast tissue. The mechanism by which sestamibi localizes to these tissues has not been established. Single photon emission computed tomography (SPECT) is then performed to detect the gamma ray emmitted by the decay of Technetium-99m to Technetium-99.

Currently available within a preparation kit for injection, Technetium Tc 99m Sestamibi is indicated for: 1) detecting coronary artery disease by localizing myocardial ischemia (reversible defects) and infarction (non-reversible defects); and 2) evaluating myocardial function and developing information for use in patient management decisions.

Pharmacodynamics

Not Available

Mechanism of action
Not Available
Absorption

At five minutes post injection about 8% of the injected dose remains in circulation. Myocardial uptake which is coronary flow dependent is 1.2% of the injected dose at rest and 1.5% of the injected dose at exercise.

Volume of distribution

Not Available

Protein binding

There is less than 1% protein binding of Technetium Tc 99m Sestamibi in plasma.

Metabolism

The agent is excreted without any evidence of metabolism.

Route of elimination

The major pathway for clearance of Tc 99m Sestamibi is the hepatobiliary system. Activity from the gall bladder appears in the intestines within one hour of injection. Twenty-seven percent of the injected dose is excreted in the urine, and approximately thirty-three percent of the injected dose is cleared through the feces in 48 hours.

Half-life

Technetium Tc 99m decays by isomeric transition with a physical half-life of 6.02 hours. Blood clearance studies indicate that the fast clearing component clears with a t½ of 4.3 minutes at rest, and clears with a t½ of 1.6 minutes under exercise conditions. The myocardial biological half-life is approximately six hours after a rest or exercise injection. The biological half-life for the liver is approximately 30 minutes after a rest or exercise injection.

Clearance

The effective half-life of clearance (which includes both the biological half-life and radionuclide decay) for the heart is approximately 3 hours, and for the liver is approximately 30 minutes, after a rest or exercise injection.

Toxicity

The following adverse reactions have been reported in > 0.5% of patients: signs and symptoms consistent with seizure occurring shortly after administration of the agent; transient arthritis; angioedema, arrhythmia, dizziness, syncope, abdominal pain, vomiting, and severe hypersensitivity characterized by dyspnea, hypotension, bradycardia, asthenia, and vomiting within two hours after a second injection of Technetium Tc 99m Sestamibi. A few cases of flushing, edema, injection site inflammation, dry mouth, fever, pruritis, rash, urticaria and fatigue have also been attributed to administration of the agent.

Translocates drugs and phospholipids across the membrane (PubMed:2897240, PubMed:35970996, PubMed:8898203, PubMed:9038218). Catalyzes the flop of phospholipids from the cytoplasmic to the exoplasmic leaflet of the apical membrane. Participates mainly to the flop of phosphatidylcholine, phosphatidylethanolamine, beta-D-glucosylceramides and sphingomyelins (PubMed:8898203). Energy-dependent efflux pump responsible for decreased drug accumulation in multidrug-resistant cells (PubMed:2897240, PubMed:35970996, PubMed:9038218)

Mediates export of organic anions and drugs from the cytoplasm (PubMed:10064732, PubMed:11114332, PubMed:16230346, PubMed:7961706, PubMed:9281595). Mediates ATP-dependent transport of glutathione and glutathione conjugates, leukotriene C4, estradiol-17-beta-o-glucuronide, methotrexate, antiviral drugs and other xenobiotics (PubMed:10064732, PubMed:11114332, PubMed:16230346, PubMed:7961706, PubMed:9281595). Confers resistance to anticancer drugs by decreasing accumulation of drug in cells, and by mediating ATP- and GSH-dependent drug export (PubMed:9281595). Hydrolyzes ATP with low efficiency (PubMed:16230346). Catalyzes the export of sphingosine 1-phosphate from mast cells independently of their degranulation (PubMed:17050692). Participates in inflammatory response by allowing export of leukotriene C4 from leukotriene C4-synthezing cells (By similarity). Mediates ATP-dependent, GSH-independent cyclic GMP-AMP (cGAMP) export (PubMed:36070769). Thus, by limiting intracellular cGAMP concentrations negatively regulates the cGAS-STING pathway (PubMed:36070769)
