Novel landmarks on the journey from natural products to pharmaceutical formulations: Phytochemical, biological, toxicological and computational activities of Satureja hortensis L.

This study examined the ethanolic extract of the Satureja hortensis L. plant's aerial parts to describe its phytochemical makeup, biological functions, toxicity tests, and in-silico molecular docking tests. The GC-MS analysis was used to evaluate the phytochemical composition of the tested extract, and the ABTS and hydrogen peroxide antioxidant assays were used to measure antioxidant activity. Aspergillus fumigatus, Candida albicans, Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Proteus vulgaris were tested for antimicrobial potential. On cell lines such as HepG-2, MCF-7, A-549, and Panc-1, the in-vitro toxicity was also examined. The A-549 cell line was also used for flow cytometry analysis of apoptosis and cell cycle. Additionally, the compounds discovered by the GC-MS analysis were used in silico tests against biological targets. Eight different phytocompounds were tentatively identified as a result of the GC-MS analysis. The compounds also demonstrated significant antioxidant potential for the ABTS and H2O2 assays (IC50: 2.44 and 28.04 µg/ml, respectively). The tested extract was found to have a range of inhibition zones and to be significantly active against the tested bacterial and fungal strains. Apoptosis and cell cycle analysis for the A-549 cell line showed that the cell cycle was arrested at S-phase, and the extract was also found to be most active against this cell line with an IC50 value of 113.05 µg/ml. The docking studies have emphasized the compounds' interactions and binding scores with the EGFR-TK target as determined by the GC-MS.

Assessment of the Quality of Saudi Patient Information Leaflets (PILs) Based on the Accuracy of Physical Description and Frequency of Solid Dosage Forms.

The physical description of dosage forms is one of the most important considerations in avoiding patient confusion and minimizing medication errors. This study aimed to determine the quality and accuracy of the physical descriptions in patient information leaflets (PILs). This cross-sectional study constituted a total of 200 drugs and PILs that were randomly selected, by pharmacy students, from Al-Dawaa community pharmacies in the Hail region of Saudi Arabia, from January 2021 to July 2021. The drugs and PILs were thoroughly evaluated in accordance with the Gulf Cooperation Council (GCC) guidelines for PILs. The accuracy screening of the total solid dosage forms (capsules + tablets) revealed that 45% showed complete accuracy and compliance, 1.5% showed poor accuracy and compliance, and 53% showed no accuracy and no compliance with the GCC guidelines and the Saudi Food and Drug Authority (SFDA) guidelines. In the frequency test, color, shape, and imprints accounted for 95.6%, 79.1%, and 73.6%, respectively. However, the size of the dosage form was the least (2.2%) used physical description feature. These findings recommend pharmaceutical companies to pay more attention to the written physical description in their PILs. Additionally, the process of PIL approval should be optimized, evaluated, and updated systematically to ensure that they contain the essential information.
