Methods: Sixty seven PIs for prescription—only medications were evaluated against a set of safety criteria published from the Ministry of Health. Results: Analyzed PIs showed many deficiencies with regard to the Ministry of Health (MOH) Investigation New Drug Application (INDA) requirements. Particularly of concern were side effects, warnings, use in pregnancy, lactation, and the storage conditions for the product. Conclusions: This study indicated that information relevant to the safe and appropriate use of medications was not uniformly mentioned in the PIs analyzed. To avoid medication errors due to deficits in the current PIs, we recommend regulatory oversight and regulator audits from pharmaceutical company, followed by enhancement of regulations requiring companies to also create patient information leaflets.展开更多

The correlation between HI and Tmax as result from rock eval pyrolysis shows that the shale of the Warukin Formation is immature while the correlation between HI and OI shows oil prone. The vitrinite (Ro) reflectance of Central Wara coal is between 0.48% up to 0.5% (immature), the content of the vitrinite group is 68.0 - 84.8 (% Vol.), Liptinite 3.0 - 14.0 (% Vol.) and inertinite 0.48 - 25.0 (% Vol.). The high content of liptinite mineral groups (14% Vol.) and the presence of exsudatinite maceral are as an initial indication of bitumenization of oil formation when there is a change in reflectance and fluorescence. Therefore, Central Wara coal plays an important role as the source rock of the Warukin Formation, although the maturity level is immature, the presence of exsudatinite maceral is believed to be the source of origin for producing oil, where the organic material comes from terrestrial.展开更多
