RESUMO
BACKGROUND: The use of natural products in skin care has been valued for their tremendous therapeutic benefits since ancient times. The current study was aimed at exploring the Leptadenia pyrotechnica plant extract and development of a stable emulgel loaded with the same extract to assess its cosmeceutical potentials. METHODOLOGY: A stable emulgel loaded with methanolic plant extract along with its control gel was prepared by homogenization. The antioxidant potential of extracts prepared in different solvents (methanol MLP, ethanol ELP, n-hexane nLP, ethyl acetate EALP, and petroleum ether PLP) was determined by DPPH scavenging activity. The presence of phytochemicals was confirmed by total phenolic and flavonoid content analysis (TPC/TFC). HPLC was used for quantification of bioactive components. FTIR analysis was performed for confirmation of functional groups. SPF was calculated via spectroscopic analysis for extract, control gel, and extract loaded emulgel. Stability studies included physical evaluation, pH, conductivity, spreadability, and rheological testing of both control and test emulgels at different temperatures, i.e., 8 °C ± 1, 25 °C ± 1, 40 °C ± 1, 40 °C ± 1 with RH of 75% for a period of 90 days. RESULTS: DPPH radical scavenging activity showed the highest antioxidant activity of 85.5% ± 2.78 for MLP. TPC and TFC were also found to be highest for the methanolic fraction, i.e., 190.98 ± 0.40 mgGAE/g and 128.28 ± 2.64 mgQE/g, respectively. The SPF of methanolic extract, placebo gel, and LPEG was 13.43 ± 0.46, 2.37 ± 0.33, and 7.28 ± 0.56, respectively. HPLC assay confirmed the presence of catechin, vanillic acid, caffeic acid, and sinapinic acid. Rheological analysis showed that formulation has pseudo-plastic flow behavior. Other stability tests also revealed that prepared emulgel is a stable one. CONCLUSION: A stable emulgel loaded with Leptadenia pyrotechnica plant extract was successfully prepared and characterized for its cosmetic effects.
RESUMO
OBJECTIVE: Drug promotion is a factor that promotes the irrational use of drugs and sometimes negatively influences the prescribing/dispensing pattern. So there was a need to assess the views about accepting gifts and attitudes/influence towards drug promotion among community pharmacists in Punjab, Pakistan. SETTING: Adopting a preused questionnaire, we conducted a cross-sectional multiple-site survey study. We distributed questionnaires to pharmacists in the community pharmacies to investigate the exposure, scepticism and acceptance to drug promotion as well as their perception about the appropriateness of gifts and to check if they had been taught about dealing with medical representatives. Data were analysed in simple percentages, and the χ2 test was used to evaluate association with demographics. All the analysis was done using SPSS V.23.0. RESULTS: A total 86.9% (463/533) pharmacists completed the survey. One out of four pharmacists reported being taught about the ethics of drug promotion (26.8%) and about how to interpret drug promotional material (25.0%) and were significantly associated with higher age (age 31%-35 years, 81.9%; p<0.05). More than two-thirds of the respondents found it appropriate to accept stationery (73.4%) and textbooks (70.6%) as gifts, and only 17.5% felt it was appropriate to accept direct money. Less than half of the pharmacists (47.3%) perceived drug companies were useful for gaining knowledge about new drugs. Majority (76.2%) thought these drug promotions play a role in the irrational prescribing of antibiotics and 18.6% dispensed antibiotics due to these promotions. CONCLUSION: The majority of pharmacists participating in this study felt it was appropriate to receive small value gifts from pharmaceutical companies. Only a small proportion of the respondents was given ethical training and education about drug promotion. Improving the syllabus and updating the pharmacist's knowledge after graduation, as part of continued pharmacy education, will eventually improve the healthcare professionals' capability to act for the patients' welfare.
