A Clinical Insight on New Discovered Molecules and Repurposed Drugs for the Treatment of COVID-19.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began churning out incredulous terror in December 2019. Within several months from its first detection in Wuhan, SARS-CoV-2 spread to the rest of the world through droplet infection, making it a pandemic situation and a healthcare emergency across the globe. The available treatment of COVID-19 was only symptomatic as the disease was new and no approved drug or vaccine was available.

A Comprehensive Investigation Regarding the Differentiation of the Procurable COVID-19 Vaccines.

COVID-19 caused by coronavirus SARS-CoV-2 became a serious threat to humankind for the past couple of years. The development of vaccine and its immediate application might be the only to escape from the grasp of this demoniac pandemic. Approximately 343 clinical trials on COVID-19 vaccines are ongoing currently, and almost all countries are motivating ongoing researches at warp speed for the development of vaccines against COVID-19.

Lipids for Taste masking and Taste assessment in pharmaceutical formulations.

Pharmaceutical products often have drawbacks of unacceptable taste and palatability which makes it quite difficult for oral administration to some special populations like pediatrics and geriatrics. To curb this issue different approaches like coating, granulation, extrusion, inclusion complexation, ion-exchange resins, etc for taste masking are employed and among them use of lipids have drawn special attention of researchers. Lipids have a lower melting point which is ideal for incorporating drugs in some of these methods like hot-melt extrusion, melt granulation, spray drying/congealing and emulsification.

Lipid Drug Carriers for Cancer Therapeutics: An Insight into Lymphatic Targeting, P-gp, CYP3A4 Modulation and Bioavailability Enhancement.

In the treatment of cancer, chemotherapy plays an important role though the efficacy of anti-cancer drug administered orally is limited, due to their poor solubility in physiological medium, inability to cross biological membrane, high Para-glycoprotein (P-gp) mediated drug efflux, and pre-systemic metabolism. These all factors cumulatively reduce drug exposure at the target site leading to multidrug resistance (MDR). Lipid based carriers systems has been explored to overcome solubility and permeability related issues of anti-cancer drugs.

Fast Dissolving/Disintegrating Dosage Forms of Natural Active Compounds and Alternative Medicines.

Fast Dissolving/Disintegrating Dosage Forms (FDDFs) are a group of dosage forms which dissolve or disintegrate quickly, leading to fast distribution of active ingredients at the site of administration; thereby providing ease of oral ingestion of solid unit dosage forms and have the potential to enhance transmucosal absorption. With time, the use of FDDFs in alternative systems has significantly increased. Homeopathic systems and traditional Chinese medicine have embraced FDDFs for the delivery of active compounds.

The Solubility-Permeability Interplay for Solubility-Enabling Oral Formulations.

The Biopharmaceutical classification system (BCS) classifies the drugs based on their intrinsic solubility and intestinal permeability. The drugs with good solubility and intestinal permeability have good bioavailability. The drugs with poor solubility and poor permeability have solubility dependent and permeability dependent bioavailability, respectively.

Transdermal applications of ethosomes - a detailed review.

Skin, the largest organ of the body serves as a potential route of drug delivery for local and systemic effects. However, the outermost layer of skin, the stratum corneum (SC) acts as a tough barrier that prevents penetration of hydrophilic and high molecular weight drugs. Ethosomes are a novel phospholipid vesicular carrier containing high ethanol concentrations and offer improved skin permeability and efficient bioavailability due to their structure and composition.

A Comparative Study of Different Proportions of Superdisintegrants: Formulation and Evaluation of Orally Disintegrating Tablets of Salbutamol Sulphate.

Objectives: Superdisintegrants play important role in disintegration of orally disintegrating tablets (ODTs). Action of three different superdisintegrants, viz. croscarmellose sodium, sodium starch glycolate and Indion 414, were studied individually or in their binary combinations for their fast disintegrant action in ODTs of salbutamol sulphate prepared by direct compression.

Formulation and characterization of taste masked ondansetron-magnesium aluminum silicate adsorption systems.

Context: Taste masking greatly influences the acceptability of bitter tasting formulation; moreover, it governs the commercial and therapeutic success of drug products.

Objective: This work is directed toward masking the bitter taste of ondansetron HCl (ONS) utilizing the excipient, which can delay the reach of drug to the taste buds.

Material And Methods: Magnesium aluminum silicate (Veegum F), a clay material having capability to adsorb the drugs onto it, was used.

Formulation and evaluation of lipid based taste masked granules of ondansetron HCl.

Introduction And Aim: Various taste masking approaches comprising the excipients which delay the reach of the drug to taste buds are reported. Lipidic substances can act as release retarding agent and provides a matrix base responsible for suppressing the bitter taste of drug. This work was aimed to study the influence of different proportions of a lipid carrier on the inhibition of bitterness of the drug vis-a-vis in vitro release of drug from the granules.

Pharmacognostic standardization with various plant parts of Desmostachya bipinnata.

Context: Desmostachya bipinnata (L.) Stapf [Gramineae (Poaceae)] has been traditionally used to treat various disorders such as asthma, kidney stone, diarrhea, wound healing, etc.

Objective: The present study involves pharmacognostic, botanical, and preliminary phytochemical examination of various plant parts and powders of D.

Formulation, evaluation and 3(2) full factorial design-based optimization of ondansetron hydrochloride incorporated taste masked microspheres.

Context: Masking the bitter taste of Ondansetron hydrochloride (ONS) may improve palatability, acceptance and compliance of ONS products.

Objective: ONS-loaded, taste-masked microspheres were prepared with a polycationic pH-sensitive polymer and 3(2) full factorial design (FFD) was applied to optimize microsphere batches.

Materials And Methods: Solvent evaporation, in acetone--methanol/liquid paraffin system, was used to prepare taste-masked ONS microspheres.

Dissolution rate enhancement of piroxicam by ordered mixing.

Micronized piroxicam was mixed with lactose, mannitol, sorbitol, maltitol and sodium chloride to produce ordered mixture in a glass vial by manual hand shaking method. The effect of excipients, surfactant, superdisintegrant, drug concentration and carrier particle size on dissolution rate was investigated. Dissolution rate studies of the prepared ordered mixtures revealed that all water soluble excipients increased the dissolution rate of piroxicam when compared to the dissolution rate of piroxicam or its suspension.

Strychnos nux-vomica seeds: Pharmacognostical standardization, extraction, and antidiabetic activity.
