Objectives: To evaluate the effect of nicorandil in prevention of reperfusion injury during primary percutaneous coronary intervention by thrombolysis in myocardial infarction flow grade scoring. Methods: A total of 140 patients from Rawalpindi Institute of Cardiology were enrolled in this study conducted from 7th September to 10th of October 2021. These participants were allocated into two major groups. Control group received conventional acute coronary syndrome protocol regimen only whereas experimental group was given nicorandil along with conventional acute coronary syndrome protocol. During primary percutaneous coronary intervention, thrombolysis in myocardial infarction flow grade scoring was analyzed and compared. Results: Majority of participants in nicorandil group achieved thrombolysis in myocardial infarction Grade-3 scoring which indicated reduced rate of no reflow phenomenon as compared to control group. A statistically significant difference was noted in score of both groups (p value = 0.001) signifying prophylactic use of nicorandil before primary percutaneous coronary intervention along with conventional acute coronary syndrome protocol is superior to only conventional acute coronary syndrome protocol regimen to cases in the control group. Conclusion: Use of nicorandil in ST elevated myocardial infarction patients before primary percutaneous coronary intervention prevents reperfusion injury thus decreasing the risk of post percutaneous coronary intervention complications and reducing mortality rate in cardiac patients suggesting its significant cardio protective role. doi: https://doi.org/10.12669/pjms.39.1.6034 How to cite this: Ilyas M, Noor M, Khan HS, Haroon S, Farhat K, Ali S.

B Background: This study aimed to evaluate the impact of Insulin Degludec Aspart on daily insulin dose in comparison with premixed insulin aspart. Methods: It was a Quasi-Experimental study conducted in the Department of Pharmacology, Army Medical College, National University of Medical Sciences, Rawalpindi and the Department of Medicine, Pak Emirates Military Hospital, Rawalpindi. One hundred and twenty participants with documented type 2 diabetes, taking premixed insulin aspart therapy were enrolled in the study. Sixty participants were substituted with insulin degludec aspart from premixed insulin aspart. Daily units of insulin were recorded for 12 weeks and compared for both groups. SPSS version 26 was used for analysing the study results. Results: Participants of the insulin degludec aspart group showed a significant reduction in the daily insulin dose compared to the premixed insulin aspart group. Fifty-two units per day were administered in the participants of the premixed insulin aspart patients while insulin degludec aspart participants received 40 units of median daily insulin dose (p-value<0.001). Conclusion: Insulin degludec aspart proved superior to premixed insulin aspart in a reduction in the daily dose of insulin with insulin degludec aspart
Objectives: To evaluate and compare the Ondansetron and Granisetron in preventing spinal anaesthesia induced hemodynamic instability in obstetric patients Methods: The comparative analytical study was conducted at Combined Military Hospital, Rawalpindi, from September to October, 2021. One hundred and twenty pregnant women undergoing cesarean section, were enrolled in the study via non probability convenience sampling, and divided into three groups containing 40 participants each based on the type of antiemetic premedication they received, if any: Group N were those not requiring antiemetic premedication, Group O consisted of those given ondansetron 4mg, and Group G had those receiving 3mg granisetron, 15 minutes prior to administration of spinal anaesthesia. Systolic blood pressures and heart rates were recorded before and at multiple intervals after spinal anaesthesia was administered. Episodes of hypotension and bradycardia were recorded. Requirement of phenylephrine and atropine as rescue drugs was recorded for each participant. Results: There was a statistically significant difference in incidence of hypotension among the three groups (p value <0.001), with both drugs being superior to the control group (p value <0.001 for both), and 3mg granisetron being superior to 4mg ondansetron (p value <0.001). As for incidence of bradycardia, ondansetron and granisetron were superior to control group (p value 0.03 and <0.001 respectively), but there was no significant difference between the two drug groups (p value 0.094). Conclusion: High dose granisetron (3mg) is superior to low dose ondansetron (4mg) in preventing hemodynamic fluctuations induced by spinal anaesthesia. doi: https://doi.org/10.12669/pjms.38.7.5585 How to cite this:Wahid M, Ali S, Yasin B, Farhat K, Noor M, Syed FT.

Objectives: To evaluate and compare the pharmacokinetic parameters, especially bioavailability, of annatto-based tocotrienol with palm tocotrienol-rich fraction in healthy human volunteers for better therapeutic outcome. Method: The systematic review was conducted between April and August 2021 in accordance with the Preferred Reporting Items for Systematic Review and Meta Analysis guidelines, and comprised search on PubMed, Google Scholar, Pakmedinet and Google search engines for open-label or double-blind randomised controlled trials involving healthy human volunteers published till January 2021. Key words used included annatto-based tocotrienol, palm tocotrienol-rich fraction, absorption and bioavailability. Boolean operators were also used, like tocotrienol AND bioavailability, annatto tocotrienol AND pharmacokinetics. Results: Of the 230 articles identified, 50(21.7%) articles met the eligibility criteria. Of them, 7(14%) were selected for data extraction and detailed analysis. Pharmacokinetic parameters of annatto-based tocotrienol were better than palm-derived tocotrienol. Oral administration of all the isomers of annatto-based tocotrienols resulted in dose-dependent increase in area under curve and plasma levels. Amongst all the isomers of annatto-based and palm-derived tocotrienol, delta isomer of annatto-based tocotrienol had the highest bioavailability with area under curve 7450±89 ng/ml, time to reach peak plasma levels 4 hours, maximum plasma concentration 1591±43 ng/nl and elimination half-life 2. 68 ±0.29 hrs. Pharmacokinetic parameters of delta isomer of annatto-based tocotrienol was greater than palm tocotrienol-rich fraction. Conclusion: Bioavailability of annatto-based tocotrienol was better than that of palm-derived tocotrienol-rich fraction. Delta isomer of annatto-based tocotrienol had the highest bioavailability amongst all isomers of tocotrienol.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
