AB  - European pharmacopoeia (Ph. Eur.) is unique reference for quality of medicines in
Europe (First issue, 1969). Collaboration of Serbia is done through expert groups,
participation at Ph. Eur. Commission, quality control of medicines in National Control
laboratory (NKL), and network of Official medicines control laboratories (OMCL). The aim of
work was to present historical data on the collaboration between Serbia, Ph. Eur. and OMCL,
by searching data from ALIMS database, which coordinates this collaboration. Collaboration
started in 1991. when Yugoslavia ratified Convention on Ph. Eur. As an independent state,
Serbia was participating in the work of Ph.Eur. Commission since 2003. Serbia has 7
representatives in expert groups: 10B,11 (Organic Chemistry), 15 (Human Vaccines and
Sera), P4 (Patent medicines), PaedF (Pediatric Formulas), POW (Powders) and ST (Standard
Terms). These experts have developed 16 new monographs, European Pediatric Formulas
and participated in revision of over 10 existing monographs. Representatives of Serbia chair
P4 and POW groups. NKL is a full member of the OMCL network since 2004, and in 2013 it
was certified against ISO 17025. Since 2006, NKL was participating in the development of
new chemical reference substances (CRS), monitoring their quality, doing laboratory
performance studies, European systematic drug quality control and studies of suspicious and
unknown samples. By active participation in development of monographs and quality
control of medicines, the competence of experts has been improved. By application of the
modern technologies this has enabled patients in Serbia to have available medicines of
equivalent quality as on the EU market.
AB  - Evropska farmakopeja (Ph. Eur.) je jedinstvena referenca za kontrolu kvaliteta lekova
u Evropi (prvo izdanje, 1969). Saradnja Srbije sa Ph. Eur. se sprovodi kroz članstvo u
ekspertskim grupama, učešće u Komisiji Ph. Eur. i kroz kontrolu kvaliteta lekova u
Nacionalnoj kontrolnoj laboratoriji (NKL) u okviru mreže nacionalnih kontrolnih
laboratorija za lekove (OMCL). Cilj rada je bio prikaz istorijskih podataka o saradnji Srbije sa
Ph. Eur. i OMCL, pretragom podataka iz baze ALIMS-a, koji koordiniše tu saradnju. Saradnja
počinje 1991. godine, kada je Jugoslavija ratifikovala Konvenciju o izradi Ph. Eur. Kao
samostalna država, Srbija od 2003.godine učestvuje u radu Komisije Ph. Eur. Srbija ima 7
predstavnika u sledećim ekspertskim grupama: 10B i 11 (Organska hemija), 15 (Humane
vakcine i serumi), P4 (Lekovi pod patentnom zaštitom), PaedF (Evropske pedijatrijske
formule), POW (Karakterizacija praškova) i ST (Standardni termini). Ovi eksperti su do sada
razvili 16 novih monografija Ph. Eur. i Evropskih pedijatrijskih formula i učestvovali u
reviziji preko 10 postojećih monografija. Predstavnici Srbije predsedavaju grupama P4 i
POW. NKL je punopravna članica OMCL mreže od 2004. godine, a 2013. je sertifikovana o
usklađenosti sa standardom ISO 17025. Od 2006. godine NKL učestvuje u razvoju novih
hemijskih referentnih supstanci (CRS), praćenju kvaliteta postojećih CRS, studijama provere
performansi laboratorije, evropskoj sistematskoj kontroli kvaliteta lekova i studijama
ispitivanja sumnjivih i nepoznatih uzoraka. Aktivnim učešćem Srbije u razvoju monografija i
ispitivanju kvaliteta lekova, poboljšana je kompetentnost eksperata i uz primenu
najsavremenijih tehnologija je omogućeno da pacijenti u Srbiji imaju dostupne lekove
ekvivalentnog kvaliteta lekovima na tržištu EU.

AB  - Torasemide was subjected to forced degradation studies. Stress conditions were varied concerning hydrolysis (acid, base, and neutral), oxidation, photolysis, and thermal degradation in order to identify the potential degradation products and consequently establish the possible degradation pathways and intrinsic stability of the drug. The study was performed according to ICH guidelines and drug was found to be relatively stable in the solid form. It showed that torasemide degraded significantly under acidic, neutral and alkaline conditions and resulted in formation of degradation product R2. When temperature was increased the degradation was accelerated. Also, the drug showed slight instability under extreme oxidative stress conditions which resulted in formation of two degradation products in total. The drug and degradation products have been separated employing gradient elution method on Zorbax SB C-18 analytical column. To characterize the degradation products LC-MSn was applied. The mass fragmentation pattern was established using single quadrupole and ion trap mass analyzers. Finally, the most possible degradation mechanism of torasemide in different experimental conditions was proposed.

AB  - Ziprasidone is known as a novel "atypical" or "second-generation" antipsychotic drug. A sensitive and reproducible method was developed and validated for determination of ziprasidone and its major impurities, which are significantly different in polarity. The separation is performed on a Waters Spherisorb (R) octadecylsilyl 1 column (5.0 mu m particle size, 250 x 4.6 mm id) using a gradient with mobile phase A [buffer acetonitrile (80+20, v/v)] and mobile phase B [buffer acetonitrile (10+90, v/v)] at a working temperature of 25 degrees C. The buffer was 0.05 M KH(2)PO(4) solution with an addition of 10 mL triethylamine/L solution, adjusted to pH 2.5 with orthophosphoric acid. The flow rate was 1.5 mL/min, and the eluate was monitored at 250 nm using a diode array detector. Optimization of the experimental conditions was performed using partial least squares regression, for which four factors were selected for optimization: buffer concentration, buffer pH, triethylamine concentration, and temperature. The proposed validated method is convenient and reliable for the assay and purity control in both raw materials and dosage forms.
