RESUMO

BACKGROUND: A Liposomal delivery system is a novel and distinguishing way of organized medicine administration. The advancements in liposomal technology allow for controlled drug distribution to treat rheumatoid arthritis effectively. Liposomes are microscopic lipid-based vesicles that have shown promise in transporting substances, such as superoxide dismutase, hemoglobin, erythrocyte interleukin-2, gamma interferon, and smaller compounds. OBJECTIVE: Liposomes are biocompatible, nontoxic, biodegradable, non-immunogenic, and flexible, with sizes ranging from 0.025 to 2.5 micrometers. LDS is normally employed to distribute drugs through topical conduits, but fresh investigation has shown that it offers promise for oral, ocular, and parenteral administration. Our major objective is to gather information about liposomes, focusing on their applicability in rheumatoid arthritis treatment. METHODS: In the current review, we have tried to cover the preparation techniques, clinical trials, patents, marketed formulations, vesicle types, formulations used to treat rheumatoid arthritis and other ailments, and layered liposomal formulations with improved characteristics. CONCLUSION: Research has established LDS as a biocompatible, sustainable, non-toxic, adaptable material. Researchers working on LDS technology in rheumatoid arthritis will find this review particularly useful as it may unclutter novel ways for therapeutic intercessions in treating the disease.

RESUMO

Fruits and vegetables (like apples, citrus, grapes, onions, parsley, etc.) are the primary dietary sources of quercetin. In addition, isolated quercetin is also available on the market as a dietary supplement with a daily dose of up to 1000 mg/d. The objective of the present study is to explore the therapeutic potential and clinical efficacy of quercetin as a dietary supplement. The present paper highlights the safety parameters and clinical trial studies with several targets reviewed from the data available on PubMed, Science Direct, ClinicalTrails. gov, and from many reputed foundations. The results of the studies prove the unique position of quercetin in the treatment of various disorders and the possibility of using phytochemicals such as quercetin for an efficient cure. As evidenced by the numerous published reports on human interventions, it has been concluded that quercetin intake significantly improves disease conditions with minimal adverse effects.

RESUMO

Inflammatory Bowel Disease (IBD), including Ulcerative Colitis (UC) and Crohn's Disease (CD), is a continuously increasing healthcare problem mainly characterized by chronic relapsing intestinal inflammation. The common symptoms of UC and CD include inflammation, diarrhea, abdominal pain, bleeding, and weight loss. IBD is generally caused by an interaction between genetic and environmental or microbial factors that influence the body's immune response and is responsible for digestive disorders and inflammation of the intestinal tract. However, a complete understanding of the pathophysiology and work-up of IBD is necessary to ensure appropriate treatment for the management of this complex disease. This review enlightens herbal therapeutics and drug delivery systems for the management of IBD, and thus provides new insights into this field and facilitates access to new treatments.

RESUMO

BACKGROUND: Hemorrhoid disease (HD) is an anal-rectal ailment that is commonly painful or may be painless and causes rectal bleeding with or without prolapsing anal tissue. It is generally associated with bleeding, prolapse, pruritus, and discomfort, which results in a diminished quality of life and well-being. OBJECTIVE: To highlight the recent developments in terms of safety, clinical efficacy, and marketed formulation for the effective management of hemorrhoids. METHOD: Reported literature available on Scopus, PubMed, Science Direct, Clinicaltrails.gov, and from many reputed foundations has been studied to summarize the recent development and clinical studies for the management of hemorrhoids. RESULTS AND CONCLUSION: The high incidence of hemorrhoids obliges the development of new molecules; therefore, safe and efficient drugs to confer protection against hemorrhoids are urgently needed. This review article mainly focuses on the newer molecules to overcome hemorrhoids and also emphasizes various studies carried out in the past.

RESUMO

BACKGROUND: Escitalopram, a selective serotonin reuptake inhibitor (SSRI), acts by increasing the serotonin level in the brain and is used widely for the management of depression and anxiety disorders. However, the poor dissolution rate of escitalopram due to less water solubility is a consequential problem confronting the pharmaceutical industry in developing pharmaceutical dosage forms for oral delivery systems. OBJECTIVE: The present work aims to deliver a novel formulation for improving the dissolution profile and, thus, the bioavailability of escitalopram. METHODS: Fast Dissolving Tablets (FDT) are expected to enable quick drug release, which will improve the drug's dissolving profile, allowing for the initial increase in plasma concentration mandatory in an acute depression attack. The use of co-processed excipients in tablets has been shown to increase the compressibility and disintegration properties of the tablets, resulting in improved in-vitro drug release and bioavailability. As co-processed excipients, a mixture of banana powder (a natural super disintegrant with nutritional value) and microcrystalline cellulose (a highly compressible substance with good wicking and absorption capacity) was used. RESULTS: The tablets were made using a response surface, randomised central composite design, and a direct compression technique. The manufactured tablets were found to be released more than 95% of the drug within 10 minutes and showed an improved drug release profile than the available marketed formulation. CONCLUSION: After confirming in-vivo potential, the fast release formulation exhibited impressive in-vitro findings and may prove to be a boon in treating acute depression attacks.

RESUMO

In search of novel effective potent therapeutic agents delivered by oral route for inflammation treatment, some novel O-propargylated-N-acetylpyrazole analogs (5a-j) were prepared by treating N-acetylpyrazole (4a-j) derived from 1,3-diarylpropenones (3a-j) with propargyl bromide. Claisen-Schmidt condensation of a series of substituted aryl ketones 1 and benzaldehydes 2 in glacial acetic acid afforded 1,3-diarylpropenones which on further treatment with hydrazine hydrate in acetic acid under reflux conditions afforded 1-acetyl-3,5-diaryl-4,5-dihydro(1H)pyrazoles (4a-j). The products were characterized by using spectroscopic techniques such as IR and NMR. In addition, the in vivo anti-inflammatory activity of the synthesized compounds was determined using the carrageenan-induced paw oedema method in rats.

RESUMO

Inflammation is a protective attempt by the organism to remove the injurious stimuli and to initiate the healing process. Also, it has been reported to be associated with the onset of various cancers. An effective anti-inflammatory drug should be able to inhibit the development of inflammation without interfering in normal homeostasis. Current approaches to overcome the inflammation include the use of immune selective anti-inflammatory derivatives, selective glucocorticoid receptor agonist, resolvins and protectins and TNF inhibitors. A number of herbal drugs have been identified in the past that can target inflammatory cytokines. This review mainly focuses on the newer molecules to combat the inflammation and also emphasise on various studies carried out in the past. Thus, the high prevalence of inflammation obliges the development of new drugs; therefore, a safe and efficient drug molecule to confer protection against inflammation is urgently needed.

RESUMO

6-Chloro-3-hydroxy-2-(5'-methylfuryl)-4H-chromene-4-one (CHMFC) has been used as an analytical reagent for the spectrophotometric determination of molybdenum. Molybdenum(VI) in the presence of several cations, anions and complexing agents forms a yellow 1:2 complex with CHMFC. The complex is quantitatively extractable into 1,2-dichloroethane from 1 mol dm(-3) acetic acid medium and is stable for more than 6 h. The complex shows an absorption maximum at 438 nm with a molar absorptivity of 5.36 x 10(4) dm3 mol(-1) cm(-1) and Sandell's sensitivity equal to 0.0017 microg Mo cm(-2). The method obeys Beer's law up to 1.9 microg Mo ml(-1). The relative standard deviations are 0.2% for solutions and 0.5-1.5% for solid samples. The method is simple, selective, precise and rapid, and has been satisfactorily applied to the micro determination of molybdenum in various synthetic and standard samples.
