Thalidomide has been used by Brazilian physicians as the drug of choice for the treatment of severe ENL since 1965, and by 1996, at least 33 cases of thalidomide embryopathy were recorded in people born in Brazil after 1965.  Since 1994, the production, dispensing, and prescription of thalidomide have been strictly controlled, requiring women to use two forms of birth control and submit to regular pregnancy tests. Despite this, cases of thalidomide embryopathy continue,   with at least 100 cases identified in Brazil between 2005 and 2010.  million thalidomide pills were distributed throughout Brazil in this time period, largely to poor Brazilians in areas with poor access to healthcare, and these cases have occurred despite the controls.
Peptides are defined as a compound of two or more amino acids in which a carboxyl group of one is united with an amino group of another. With the elimination of a water molecule, a peptide bond is formed. To put it more simply, peptides are just small proteins. When the number of amino acids are less than 50, these are peptides. When higher than 50, these are proteins. The peptides are therefore small chains of amino acid which are present in all cells of the body. There are several kinds of peptides: oligopeptides, polymers, proteins, neuropeptides and peptide hormones. These are synthesized naturally by the body. Peptides will therefore be used primarily to make a more abundant amount of hormones in the body. The latter will then produce new hormones such as Testosterone or corticosteroids. It is these two hormones that are considered anabolic or indirect anti-inflammatory.
