The present research was envisaged on the development of dry powder to treat asthma. Terbutaline sulphate (a bronchodilator) and Itraconazole (an antifungal) were used in the present study for bronchodilation and allergy to Aspergillus fumigatus (fungi) using lactose and trehalose as excipients. Dry powder insufflations were prepared by physical mixing (milling) and spray drying, out of which spray dried formulations with lactose as excipient gave the best results in-vitro. Hence, spray dried formulations were preceded for further pharmacokinetic and stability studies. The pulmonary concentrations of Terbutaline sulphate and Itraconazole from TER – A (sd), ITR – A (sd), TER: ITR – A (sd) monotonically decreased (Tmax = 0 min). However, Itraconazole showed higher AUC0-α in individual and combined formulation when compared to Terbutaline sulphate showing slower elimination of Itraconazole. From plasma pharmacokinetic data Tmax of Itraconazole formulations ITR – A (sd), TER: ITR – A (sd) was high when compared to the formulations of Terbutaline sulphate TER – A (sd), TER: ITR – A (sd) showing lower systemic bioavailability...

Arylpropionic acid derivatives are an important class of NSAIDs. Ibuprofen, 2- (4-isobutylphenyl) propionic acid, is known as NSAIDs. Arylpropionic acid derivatives have a broad biological activity, including antibacterial, anticonvulsant and anticancer activity, analgesic, and anti-inflammatory. In addition to the most powerful ingredients used in analgesic and antipyretic fields, such as ibuprofen, Oxaprozin, Ketoprofen, and Phenoprofen, aryl propionic acid derivatives play an important role in treating other symptoms. The possible improvements in the activity can be further achieved by slight modifications in the substituent on the basic aryl propionic acid. According to Grigoryan et al., 2019 studies reveal that the replacement of the carboxyl group by tetrazole ring, hydroxamate, ester, alcohol, and amide groups forms compound showing lower activity (anti-inflammatory, anti-nociceptive, ulcerogenic activity). The presence of a carboxyl group in the parent molecule of aryl propionic acid is important for broad-spectrum pharmacological activity. This review focused on recent advances and recent research on aryl propionic acid derivatives compared to medicinal...

The late December of 2019 witnessed an outbreak of viral pneumonia of unknown etiology (VPUE) in the Wuhan city of Hubei province, China. Later it was identified as a novel strain of β-genus Coronavirus, which is similar to the Severe Acute Respiratory Syndrome (SARS) virus, which was a global pandemic during 2002-03. This novel coronavirus is rapidly spreading with an R0 of 2 and has an incubation period of 2-14 days. It spreads through human-to-human transmission and by fomites (articles and surfaces contaminated by affected persons). The World Health Organization acted immediately to prevent the spread of the virus by declaring it as a Public Health Emergency of International Concern (PHEIC). It has been declared as a pandemic, and several sets of guidelines have been issued by WHO, including social distancing norms and hygiene practices yet, this novel coronavirus continues to spread at an alarming rate leading to many fatalities across the globe. Since this novel coronavirus shares similar characteristics with other coronaviruses, some of the known treatment options...

Background: Cardiovascular disease (CVD) is the leading cause of death worldwide. Management of behavioral risk factors is recommended for primary and secondary prevention of CVDs. There is evidence that the involvement of community pharmacies in health promotion activities is successful. Objectives: This study was conducted to assess community pharmacists’ perception and current practice in providing lifestyle assistance to patients with cardiovascular disease and to identify potential barriers to the provision of lifestyle assistance in Klang Valley, Malaysia. Method: A cross-sectional study was conducted among community pharmacists in Klang Valley using convenience sampling. A self-administered 54-item questionnaire was used to collect information on the current practice and perception of community pharmacists, and potential barriers in providing lifestyle assistance to patients with cardiovascular disease. Results: The response rate was 62.8%. Most of the services investigated were available in the pharmacy except for advice on alcohol consumption (52.7%) and screening and/or monitoring services for obesity (57.7%), which are less likely to be available. For most of the listed activities in relation to...

Rumex obtusifolius, belonging to the Polygonaceae family, commonly known as ‘broad-leaf-dock’ is one of the most important medicinal plants. It is common wayside weeds and uses as an antidote to nettle, depurative, astringent, laxative, and tonic and in the treatment of sores, blisters, jaundice, burns, cancer, and tumors. In this study, we design to synthesize silver nanoparticles from silver nitrate via a green route using the aqueous leaf extracts of Rumex obtusifolius. This biogenic reduction of metal ion to base metal is quite rapid, readily conducted at room temperature and pressure, and easily scaled up. The use of silver nanoparticles is gaining popularity due to its antibacterial properties. The silver nanoparticles formation in the solution was monitored by UV-Vis spectroscopy, and further characterization was carried out by FT-IR (Fourier Transform Infrared Spectroscopy), XRD (X-ray Diffraction), SEM (Scanning Electron Microscopy) and TEM (Transmission Electron Microscopy) analysis. To optimize the biosynthesis of silver nanoparticles, the effect of process variables such as extract concentrations, the mixing ratio of the reactants, time, and...
