Bortezomib, sold under the brand name Velcade among others, is an anti-cancer medication used to treat multiple myeloma and mantle cell lymphoma. [4] This includes multiple myeloma in those who have and have not previously received treatment. [3] It is generally used together with other medications. [3] It is given by injection. [4]
Bortezomib (Velcade) was approved in 2003. This was the first proteasome inhibitor approved for use in the U.S. Its boron atom binds the catalytic site of the 26S proteasome. [20] Carfilzomib (Kyprolis) was approved by the FDA for relapsed and refractory multiple myeloma in 2012 . [21]
Boronic acids are used extensively in organic chemistry as chemical building blocks and intermediates predominantly in the Suzuki coupling. A key concept in its chemistry is transmetallation of its organic residue to a transition metal. The compound bortezomib with a boronic acid group is a drug used in chemotherapy.
Bortezomib/dexamethasone is a combination drug against multiple myeloma. [1] When bortezomib is used by the trade name Velcade, the combination is called Vel/Dex (or Vel-Dex or Veldex ). Bortezomib is a proteasome inhibitor and dexamethasone is a corticosteroid .
Effervescent or carbon tablets are tablets which are designed to dissolve in water and release carbon dioxide. The carbon dioxide is generated by a reaction of a compound containing bicarbonate , such as sodium bicarbonate or magnesium bicarbonate , with an acid such as citric acid or tartaric acid .
A pastille is a type of sweet or medicinal pill made of a thick liquid that has been solidified and is meant to be consumed by light chewing and allowing it to dissolve in the mouth.

American soldiers were issued a first-aid kit containing sulfa pills and powder and were told to sprinkle it on any open wound. [15] The sulfanilamide compound is more active in the protonated form. The drug has very low solubility and sometimes can crystallize in the kidneys, due to its first pK a of around 10.
In its crystalline form it is a brittle, dark, lustrous metalloid; in its amorphous form it is a brown powder. As the lightest element of the boron group it has three valence electrons for forming covalent bonds , resulting in many compounds such as boric acid , the mineral sodium borate , and the ultra-hard crystals of boron carbide and boron ...
