“…The samples were first crushed and sieved, when necessary, homogenized, weighed (approximately 200 mg) and placed into polyethylene tubes. The irradiation was performed at the TRIGA IPR-R1 reactor of CDTN (Jacimovic, Leal et al, 2008) according TO the conditions and parameters presented in Table II.…”

“…Uma das questões relativas à qualidade de medicamentos manipulados, evidenciadas em estudos recentes, é a presença de contaminantes inorgânicos incluindo metais [27][28] . Mesmo em baixas concentrações, da ordem de mg/g, a ingestão de elementos não essenciais pode ser prejudicial à saúde se consumidos por longo prazo [29][30][31] .…”

“…The prudent judgment of the pharmacist, who must be a qualified professional for this purpose, is another fundamental aspect. Additionally, an appropriate profile with a proven stability must be sought in the literature [11][12][13][14].…”

“…In order to evaluate the presence and concentration of chemical elements, the technique used in this study was neutron activation analysis (NAA), applying the k 0 -standardization method [23][24][25]. The neutron activation analysis is a very sensitive and reliable multielemental technique, suitable for determination of the elements such as: As, Ba, Br, Ca, Ce, Cl, Co, Cr, Eu, Fe, Hf, Mg, Mn, Na, Sb, Sc, Sm, Ti and Zn, in different drugs [14]. The technique is based on the principle that when the material is irradiated by neutrons, some elements with suitable nuclear characteristics become radioactive isotopes.…”
