One of the major limitations of radiotherapy is that the cells of solid tumors become deficient in oxygen. Solid tumors can outgrow their blood supply, causing a low-oxygen state known as hypoxia . Oxygen is a potent radiosensitizer, increasing the effectiveness of a given dose of radiation by forming DNA-damaging free radicals.
Radiopharmacology is radiochemistry applied to medicine and thus the pharmacology of radiopharmaceuticals (medicinal radiocompounds, that is, pharmaceutical drugs that are radioactive). Radiopharmaceuticals are used in the field of nuclear medicine as radioactive tracers in medical imaging and in therapy for many diseases (for example ...
Radiopharmaceuticals, or medicinal radiocompounds, are a group of pharmaceutical drugs containing radioactive isotopes. Radiopharmaceuticals can be used as diagnostic and therapeutic agents. Radiopharmaceuticals emit radiation themselves, which is different from contrast media which absorb or alter external electromagnetism or ultrasound.
Theranostics, also known as theragnostics, [1] is a technique commonly used in personalised medicine.For example in nuclear medicine, one radioactive drug is used to identify and a second radioactive drug is used to treat (therapy) cancerous tumors.
The concept of nuclear pharmacy was first described in 1960 by Captain William H. Briner while at the National Institutes of Health (NIH) in Bethesda, Maryland.Along with Mr. Briner, John E. Christian, who was a professor in the School of Pharmacy at Purdue University, had written articles and contributed in other ways to set the stage of nuclear pharmacy.
It was discovered in 1905 by T. Godlewski, [2] [3] [4] a Polish chemist from Kraków, and was historically known as actinium X (AcX). [ 5 ] [ 6 ] Radium-223 dichloride is an alpha particle-emitting radiotherapy drug that mimics calcium and forms complexes with hydroxyapatite at areas of increased bone turnover. [ 7 ]
Radiation therapy (RT) is in itself painless, but has iatrogenic side effect risks. Many low-dose palliative treatments (for example, radiation therapy to bony metastases) cause minimal or no side effects, although short-term pain flare-up can be experienced in the days following treatment due to oedema compressing nerves in the treated area ...
E. W. Kemble's "Death's Laboratory" on the cover of Collier's (June 3, 1905). A patent medicine, also known as a proprietary medicine or a nostrum (from the Latin nostrum remedium, or "our remedy") is a commercial product advertised to consumers as an over-the-counter medicine, generally for a variety of ailments, without regard to its actual effectiveness or the potential for harmful side ...
