ABSTRACT

A new type of coronavirus (severe acute respiratory syndrome coronavirus 2; SARS-CoV-2) that has began in Wuhan, China in late 2019 has grasped the whole world. Since then, there are approximately 2.59 million deaths has been caused by Covid-19. After numerous attempts and hard work from healthcare system, this deadly virus is in control by using vaccines like Covaxin and Covishield. But new problems are emerging even after the  discovery of vaccines. Patients have been experiencing various health problems after recovering from Covid-19. This review article discussed about different sequalae and syndromes that are emerging in patients after postcovid recovery.

Keywords: Covid-19, Sequalae, Syndrome, Postrecovery symptoms.

ABSTRACT

Anticoagulant therapy being the most conventional form of therapeutic intervention is the cornerstone for the treatment and prevention of various ailments including Atrial Fibrillation (AF), Acute Coronary Syndrome (ACS), Venous Thromboembolism (VTE) and patients undertaking cardiac procedures¹. Bleeding is the principal complication of anticoagulants even though used within its therapeutic limit. An innovative tool HAS-BLED score come up with the assessment of bleeding risk among patients under anticoagulant therapy supporting the physicians in a better clinical decision making^2,3. The objective is to evaluate drug use and bleeding risk of anticoagulant drugs using HAS-BLED Score among geriatric patients. A prospective observational study was conducted in a tertiary care hospital among hundred patients for a period of six months. It was found that 61% were males and 49% were females. Most of the patients were from the age group of 65-70 (53%), 71-75 (31%) and least less than 75 (16%). The most commonly prescribed dosage form was parenteral (79%) and drug was heparin (52%). The bleeding risk of twenty patients taking warfarin was assessed using HAS- BLED Score, the risk categories shows greater than or equal to 3 (60%) high risk and score between 1-2 (40%) moderate risk. Drug use pattern of anticoagulants needs uninterrupted and repeated surveillance not only to discern therapeutic efficacy but also to scrutinize potential adverse drug reaction. From the HAS-BLED score distribution of patients taking warfarin conveys the need to monitor the parameters especially INR before and after initiation of anticoagulant therapy.

ABSTRACT

This research work was carried out on the species Nephrolepis biserrata (Sw.) Schott (Nephrolepidaceae), a fern from Côte d’Ivoire with the aim of establishing its phytochemical, antioxidant and biological profile. The results obtained from the phytochemical screening show that said species contains alkaloids, coumarins, flavonoids, polyphenols, sterols, terpenes, and tannins. The antioxidant activity was evaluated spectrophotometrically against the DPPH radical in comparison with that of vitamin C. The determination of the antibacterial parameters indicates that N. biserrata doesn’t exhibit any bactericidal action against the bacterial strains tested. Regarding the vermicidal activity against earthworms, decocts of N. biserrata showed an anthelmintic effect, which however remains less pronounced than that of albendazole, the anthelmintic antiparasitic taken as a reference.

ABSTRACT

Hepatorenal syndrome (HRS) is a potentially reversible renal impairment where the kidney function is stopped due to renal vasoconstriction resulting from extreme vasodilation. This case report describes a 64 year old female with Decompensated Chronic Liver Disease. Her clinical history and physical findings shows a decreased renal function secondary to chronic liver disease and was later diagnosed as HRS. HRS can be managed effectively with Terlipressin, Midodrine, Albumin. Such combination therapy at the early stage of diagnosis can prevent further complications.

Keywords: HRS, CLD, Albumin, Terlipressin, Midodrine.

ABSTRACT

The entire world is facing a worst situation of pandemic ever. It’s been more than 18 months after the initial reports on Covid from China, and the pandemic is still going.  As per the data available over the WHO website as of 23 June 2021, there have been 178,837,204 confirmed cases of COVID-19, including 3,880,450 deaths, reported to WHO. As of 21 June 2021, a total of 2,414,347,324 vaccine doses have been administered. Despite of having more than 15 vaccines for Covid-19; the challenge to treat a patient with a define line of treatment remains the same. In the present review we have made an attempt to summarize the various medicines which are being used by medical practitioner in India and overseas. Use of different drug molecules like Remdesivir, Tocilzumab, Hydroxychloroquine, Azithromycine, Ivermectin, Steroids, Doxicycline, Ecosprine, Low molecular weight Heparin, Lopinavir and Ritonavir, Nitazoxanide, Baricitinib etc. were highlighted; although the list is long. A focus is made on the different types of vaccines available till date and their status in various countries.

ABSTRACT

Recently, solid lipid Nano-particles have received much attention by the researchers owing to its biodegradability, biocompatibility and the ability to deliver a wide range of drugs. The aim of the present study was to design Diltiazem solid lipid Nano-particles and to evaluate them. Diltiazem solid lipid Nano-particles were prepared by hot homogenization technique using different lipids (Tristearin, GMS and Comprital), soy lecithin as stabilizers and tween 80, Poloxamer as surfactants. The Nano-particles were evaluated for particle size & PDI, zeta potential, entrapment efficiency and in vitro drug release. The particle size ranged from 49.7 to 523.7 nm. PDI of all formulations were good within the range of 0.189 to 0.427. The zeta potential ranged from -10.5 to -29.6 Mv, Entrapment efficiency of all formulations were observed was in the range of 78.68 to 95.23 %. The cumulative percentage release of Diltiazem from different Diltiazem Nano-particles varied from 53.36 to 88.74% depending upon the drug lipid ratio and the type of lipid used. The average percentage of drug released from different SLNs after 24 hours showed in the following order: F9 (53.35%) < F6 (56.75%) < F4 (61.74%) < F7 (63.8%) < F5(67.77%) < F8(69.04%) < F3(75.31%) < F1(79.36%)

ABSTRACT

Bilayer floating tablets of Dothiepin HCL were developed by direct compression method. Immediate release layer contains 30 mg of drug and super disintegrant sodium starch glycolate, serves the purpose of loading dose. Sustained release layer contained HPMC K4M, natural polymers like xanthan gum, guar gum, karaya gum release the drug for 12 hours’ time. Sodium bicarbonate and citric acid are used to produce effervescence. Floating lag time of optimized tablet is 92 sec, whereas floating duration is more than 12 hours. FTIR results revealed that there was no interaction between drug and HPMC K4M / xanthan gum. The post compression parameters of developed tablets were found to be satisfactory. In this study, it was confirmed that the formulations containing HPMC K4M, have shown better floating properties and finally the formulation containing a combination of HPMC K4M and xanthan gum in 3:1 ratio, has exhibited decent sustained drug release properties. The release kinetics of optimized formulation prepared with the combination of HPMC K4M and xanthan gum followed zero order kinetics.
