Aspirin Aspirin Aspirin, also known as acetylsalicylic acid (ASA), is a medication used to treat pain, fever, or inflammation. Specific inflammatory conditions in which aspirin is used include Kawasaki disease, pericarditis, and rheumatic fever. Aspirin given shortly after a heart attack decreases the risk of death. Aspirin is also used long-term to help prevent further heart attacks, ischaemic strokes, and blood clots in people at high risk. It may also decrease the risk of certain types of cancer, particularly colorectal cancer. For pain or fever, effects typically begin within 30 minutes. Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) and works similar
Technetium (99mTc) medronic acid Technetium (99mTc) medronic acid Technetium (Tc) medronic acid (MDP) is a pharmaceutical product used in nuclear medicine to localize bone metastases as well as other diseases that can alter the natural turn-over in the bone by bone scintigraphy. The drug is a complex of medronic acid, the simplest bisphosphonate, with technetium-99m (Tc), a radionuclide that emits gamma rays. The exact structure of the complex is not known. Tc-MDP must be prepared in a radiopharmacy. It is usually supplied as a "cold kit" to which radioactive Tc from a generator is added. Kit composition may vary between suppliers, but contents typically
