    Background: In Malaysia, community pharmacies play an important and vital role in both urban and rural areas with approximately 30% of 12,000 registered pharmacists with annual retention certificate practicing in community pharmacies. The main objective of this study was to find the perception of respondents on the value and necessity of pharmacists.

    Materials and Methods: The questionnaire was divided into two sections: the first section assessed the visits to community pharmacies, purpose, interaction with pharmacy staffs, professional fee, and improvements to pharmacy practices; the second section evaluated the characteristics of respondents including an e-consent form. Data were analyzed using the Statistical Package for the Social Sciences software (version 11.5).

    Results: The highest number of respondents (66.1%) consulted with the pharmacists for cough and cold, 33.1% for gastric and stomach ailments, and 28.9% for diarrhea and constipation. Only 34% of cases were handled by the pharmacists, whereas 52.1% by the sales assistant. Approximately 88.5% showed satisfaction with the counseling provided. A total of 46.3% did not know whom they dealt with, whereas 51.2% wanted personal attention of the pharmacists instead of the sales assistants. However, 66.9% of respondents preferred to a private consultation room. Records of only 32.2% of respondents were secured by the pharmacies, whereas 42.1% showed interest to pay a professional fee. Moreover, 83.3% agreed the fee of RM5 only, whereas 20.8% agreed to RM10. Among the respondents, majority agreed to pay a fee willingly, but approximately 30% stayed neutral.

    Conclusion: There is a need for the community pharmacists to play vital roles firsthand at the front desk to serve the patients professionally instead of handing over the responsibilities to the sales assistant.

    Cancer management presents multifarious problems. Triple negative breast cancer (TNBC) is associated with inaccurate prognosis and limited chemotherapeutic options. Betulinic acid (BA) prevents angiogenesis and causes apoptosis of TNBC cells. NIH recommends BA for rapid access in cancer chemotherapy because of its cell-specific toxicity. BA however faces major challenges in therapeutic practices due to its limited solubility and cellular entree. We report lactoferrin (Lf) attached BA nanoparticles (Lf-BAnp) for rapid delivery in triple negative breast (MDA-MB-231) and laryngeal (HEp-2) cancer cell types. Lf association was confirmed by SDS-PAGE and FT-IR analysis. Average hydrodynamic size of Lf-BAnp was 147.7 ± 6.20 nm with ζ potential of -28.51 ± 3.52 mV. BA entrapment efficiency was 75.38 ± 2.70% and the release mechanism followed non-fickian pattern. Impact of Lf-BAnp on cell cycle and cytotoxicity of triple negative breast cancer and its metastatic site laryngeal cancer cell lines were analyzed. Lf-BAnp demonstrated strong anti-proliferative and cytotoxic effects, along with increased sub-G1 population and reduced number of cells in G1 and G2/M phases of the cell cycle, confirming reduced cell proliferation and significant cell death. Speedy intracellular entry of Lf-BAnp occurred within 30 min. Lf-BAnp design was explored for the first time as safer chemotherapeutic arsenals against complex TNBC conditions.

    Transdermal Drug Delivery Systems (TDDS) have emerged as a promising method for administering therapeutic agents due to their non-invasive nature and patient-friendly approach. However, the effectiveness of this system is limited to drugs with specific physicochemical properties that allow for transdermal delivery as the skin acts as a barrier. To address this limitation, researchers have been exploring alternative approaches to improve drug delivery through the stratum corneum, ensuring consistent drug distribution at controlled rates. Thirdgeneration delivery systems have been developed to facilitate the delivery of various drugs across the skin barrier by disrupting the stratum corneum while protecting deeper skin tissues from injury. This review has explored various approaches that have gained popularity in enhancing drug delivery through TDDS, including microneedle-mediated, nanoparticle-enabled, thermal ablation-enhanced, and electroporation-driven delivery systems. It has discussed the mechanisms of drug delivery and potential applications for different types of drugs and detailed the clinical studies. This review has also highlighted the significant advancements in TDDS, offering valuable insights into both the pharmaceutical field and biomedical applications. The continued exploration and refinement of these delivery systems, particularly with the incorporation of Internet-of-Things (IoT) technology, Artificial Intelligence (AI), and machine learning, hold promise for expanding the scope of therapeutic interventions.
