Opis:
Low drug loading efficiency is the limiting factor in the use of pre-fabricated filaments for 3D printing of pharmaceuticals. The aim of present study was to modify the material properties of pre-fabricated filament by incorporating the suitable solubilizing aids in order to enhance the drug loading efficiency. Loratadine was loaded into PVA filaments by using solubilizers (Soluplus®, Sodium lauryl sulphate) and plasticizers (glycerin and Polyethylene glycol-400) and the printability of filaments was investigated. The treated filaments were characterized for morphology and diameter changes, drug content, FTIR and thermal properties and printed into tablets of suitable dimensions. The printed tablets were also characterized for drug assay and drug release. The results have shown that the surface of different drug loaded filaments become rough with almost no change in diameter hence, these filaments remained printable. However, there was 7 to 24 times enhancement in drug content of filaments treated with particularly those pretreated with glycerin and soaked in drug solution containing Soluplus. The printed tablets have also shown almost similar drug content as their precursor filaments and the release followed diffusion mechanism in most of the formulations. The study concludes that the treatment of PVA filament with solubilizer aids has significantly improved the drug loading entrapment without compromising the printability.

Opis:
Viral gastroenteritis and other water-borne diseases are the most neglected areas of research in Pakistan. To determine the quality of water, 4 enteric viruses were studied from different localities of Peshawar, Pakistan. The study validates the viral detection method for Rotavirus (RV), Human adenovirus (HAdV), Enterovirus (EV) and Hepatitis A virus (HAV), directly from water sources of rural areas of Peshawar, KPK, Pakistan. Overall, 95 five water samples were tested; among them, 9.47% were positive for RV, 38.94% for HAdV, 48.42% for EV and 12.63% for HAV. The presence of these viruses in water was directly correlated with meteorological data. High prevalence of EV and HAdV was detected frequently in the wet season from May – September, which can be the potential cause of spreading of gastroenteritis in the population. Environmental surveillance is an additional tool to evaluate the epidemiology of enteric viruses circulating in a given community.
