The pharmacokinetics of indecainide in mice, rats, dogs, and monkeys

Drug Metabolism and Disposition : the Biological Fate of Chemicals
T D Lindstrom, G W Whitaker


The pharmacokinetics of indecainide, a new antiarrhythmic agent, were studied in mice, rats, dogs, and monkeys. The drug was well absorbed in all species tested resulting in peak plasma levels of drug within 2 hr. The plasma half-life of indecainide after acute oral administration was 3-5 hr in rats, dogs, and monkeys but considerably shorter in mice. The plasma half-life of indecainide was dose-dependent in dogs and increased slightly with chronic dosing. Peak plasma levels of drug were also dose-dependent in dogs and monkeys. Fecal elimination was the primary route of excretion of the drug in rats and mice after oral dosing. Fifty per cent of the dose was excreted in the bile of rats which was then subject to enterohepatic circulation. Urinary elimination was the predominant excretory route in the dog. Tissue distribution of radioactivity in rats showed that tissues which first encounter the drug have the highest levels of radioactivity. The highest concentrations were found in the stomach, intestine, liver, and kidney, whereas very low levels were observed in the fat and brain. Except for liver and kidney, only very low levels were present after 24 hr.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

The Tendon Seed Network

Tendons are rich in the extracellular matrix and are abundant throughout the body providing essential roles including structure and mobility. The transcriptome of tendons is being compiled to understand the micro-anatomical functioning of tendons. Discover the latest research pertaining to the Tendon Seed Network here.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.


Incretins are metabolic hormones that stimulate a decrease in glucose levels in the blood and they have been implicated in glycemic regulation in the remission phase of type 1 diabetes. Here is the latest research.

Chromatin Regulation and Circadian Clocks

The circadian clock plays an important role in regulating transcriptional dynamics through changes in chromatin folding and remodelling. Discover the latest research on Chromatin Regulation and Circadian Clocks here.

Long COVID-19

“Long Covid-19” describes illness in patients who are reporting long-lasting effects of the SARS-CoV-19 infection, often long after they have recovered from acute Covid-19. Ongoing health issues often reported include low exercise tolerance and breathing difficulties, chronic tiredness, and mental health problems such as post-traumatic stress disorder and depression. This feed follows the latest research into Long Covid.

Spatio-Temporal Regulation of DNA Repair

DNA repair is a complex process regulated by several different classes of enzymes, including ligases, endonucleases, and polymerases. This feed focuses on the spatial and temporal regulation that accompanies DNA damage signaling and repair enzymes and processes.
