Treatment

ExcerptReference
"Pidotimod treatment was able of significantly reducing the number of children with upper and lower airways symptoms, and medications use, increasing school attendance, and reducing pediatric visits for RRI."( Artusio, L; Caimmi, S; De Amici, M; Licari, A; Marseglia, A; Marseglia, GL; Nigrisoli, S, 2014)

Drug Classes (1)

ClassDescription
peptideAmide derived from two or more amino carboxylic acid molecules (the same or different) by formation of a covalent bond from the carbonyl carbon of one to the nitrogen atom of another with formal loss of water. The term is usually applied to structures formed from alpha-amino acids, but it includes those derived from any amino carboxylic acid. X = OH, OR, NH2, NHR, etc.
