Methyl and ethyl ester showed potent peripheral analgesia with 82.09% and 82.59% writhing inhibition, respectively compared to that of naproxen (64.68% inhibition) at equivalent dose of 25 mg/kg bw. In antiinflammatory study, all the three esters generated 96.75%, 91.54% and 90.65% inhibition of inflammation at 5th hour, similar to that obtained by naproxen (95.12% inhibition). Molecular docking study suggested that methyl ester had the highest binding energy towards COX-2 enzyme, while isopropyl ester possessed the lowest energy, and also exhibited the lower Vander Waals interaction that might affect COX inhibition. Moreover, all the compounds had satisfactory ADME profile. Again, methyl ester satisfied the safety issues, while other compounds might have cardio toxicity.\u0000Dhaka Univ. J. Pharm.

So, the purpose of the study was to develop and characterize pitavastatin-loaded liposomes to achieve sustained release of the drug by increasing the solubility as well as bioavailability in treating hyperlipidemia. All formulations were prepared using the ether injection method (EIM) to determine the effect of three independent factors lecithin, cholesterol, and chitosan/PEG-6000 on two dependent variables of percent drug entrapment efficiency (% DEE) and percent cumulative drug release (% CDR) at low (-1) and high (+1) levels, respectively. The prepared liposomes were analyzed using various techniques, including percent DEE, percent CDR, FTIR, S0EM, and zeta potential. After 8 hours of dissolution, the lowest and highest drug releases were 78.01 and 88.70 percent, 68.12 and 80.19 percent, and 66.22 and 78.91 percent, for FCH-4 and FCH-2, FLE-1 and FLE-3, and FPEG-4 and FPEG-3, respectively. Additionally, permeability experiments were conducted by in vitro and ex vivo methods. The particle size of liposomes was between 3.51 μm to 4.19 μm that gave evidence of the formation of uni-lamellar vesicles. The release kinetics were investigated using a variety of mathematical models. SEM and FTIR analyses indicated that liposomes have a spherical and smooth surface with no interaction between medications and excipients. Comparative in vitro and ex vivo studies demonstrated that pitavastatin calcium-loaded liposomes may be viable for patients with hyperlipidemia due to their enhanced solubility and bioavailability.\u0000Dhaka Univ.

However, it does not always support a suitable dose regimen due to its low bioavailability and half-life. The purpose of this study was to develop and analyze repaglinide loaded control release liposomes to provide suitable dosage form to treat diabetes. Repaglinide loaded liposomes were prepared by modified ether injection method. According to the USP-II paddle method, in vitro dissolution studies of liposomes were performed for 8 hours in phosphate buffer (pH 7.4). The stability study was executed according to ICH guidelines under three different environmental conditions for 14 days. Additionally, the presence and size of liposomal vesicles was confirmed by microscopic observation. The formulations containing phosphatidylcholine and cholesterol at a molar ratio of 1:0.4 revealed the highest drug entrapment efficiency of 73.1% with an optimum stirring rate of 300 RPM. The pegylated liposomes (PEG400/1500) prolonged the drug loading capacity for the formulations compared to non-pegylated liposomes. On the contrary, the addition of nigella oil caused a decrease in entrapment efficiencies of the liposomes. Most of the formulations followed zero order kinetic model and supper class II release mechanism. In vitro dissolution showed controlled release pattern of the liposomes and maximum drug release after 8 hours was 92.64%. Additionally, all the liposomal formulations were found to be more stable at refrigeration temperature (5 ± 2ºC) where pegylated liposomes were most stable over 14 days at three different environmental conditions. Visual observation under an optical microscope, the vesicular structure of liposomes was confirmed.\u0000Dhaka Univ. J. Pharm.

Pharmacists may offer service in this regard to strengthen pharmacovigilance if given the appropriate opportunity. To evaluate their preparedness, the current cross-sectional study aims to assess the knowledge, attitude and perception (KAP) of pharmacy students about the ADR reporting system. A validated self-administered and structured questionnaire was filled out online upon informed consent by 400 final-year and master-level participants from 22 public and private universities. Data analysis was done using the Statistical Package for Social Science (SPSS, v.23.0) and Microsoft Excel. The average knowledge score of the students came out as 2.93 (SD=0.6) out of 5. While fundamental knowledge regarding ADR was displayed well by the participants such as agreeing to ‘side effects and ADRs are different’ (85%), advanced conceptual understanding exhibited lacking. For example, variable like ‘distinguishing between ADR and an adverse drug event’, ‘not all ADRs are known before a drug is marketed’, and ‘before ADR reporting, drug’s association needs no confirmation’ showed 14%, 41% and 5% correctness, respectively. However, 98% of the participants emphasized the need for ADR reporting, in both serious and non-serious cases, 85% knew that anybody can report ADR and approximately the same percentage of students could identify the organization receiving reports. Less than half (47%) were familiar with the authorized ADR reporting form and 40% reportedly claimed that they knew when and how to report. The need for more relevant education about this was supported by most of the students (91.8%). Participants mostly agreed about the need for reporting and gaining more overall awareness about the ADR reporting procedure. The findings suggest that increased knowledge, training, assertiveness and practice among all stakeholders are necessary for a spontaneous ADR reporting system in the country.\u0000Dhaka Univ. J.

The objective of the present work was to develop a formulation of an oral controlled-release (CR) metformin tablet, using hydrophilic hydroxylpropylmethylcellulose (HPMC) grades K4M and K100M polymers at different concentrations utilizing computational simulatory tools. Intestinal membrane permeability of the drug has been assayed using 2 hours simulation run with MembranePlus Software. Simulated environment generated for in silico dissolution study, using DDDPlus software, of the prepared formulations used USP Apparatus Type 2 rotating at 100 rpm. The simulation run was for 2 hours using 0.1N HCl phase followed by 8 hours with 6.8 USP Phosphate buffer phase. The results showed that drug release from the higher viscosity grade, K100M was slower as compared to the lower viscosity grade K4M at a fixed polymer concentration level. Furthermore, plasma concentration-time curves for the formulations have been generated using GastroPlus software.\u0000Dhaka Univ. J. Pharm.
