Nanotechnology has brought about a significant change in the drug delivery system. A plethora of BCS class II drugs are formulated as solid lipid nanoparticles (SLN) due to its poor solubility and bioavailability and has potential applications in drug delivery system. The formulation of SLN involves use of a different type of surfactants and lipids in different concentrations which has shown a greater impact on various physicochemical parameters such as entrapment efficiency, drug release, particle size, zeta potential, storage and stability of the drug. Apart from its unique size-dependent property, merits and demerits, different excipients characterization technique, scale up, storage and stability are...

Conventional oral dosage forms posses low bioavailability problems due to their rapid gastric transition from the stomach. Especially some drug which is less soluble in alkaline pH and producing local action in the stomach gets rapidly emptied and do not get enough residence time in the stomach. As a result, there is a requirement of increased frequency of dose. To overcome such type of problems various efforts have been made by developing the gastro-retentive drug delivery system. The gastro-retentive drug delivery system comprised mainly of floating, mucoadhesive, swellable and high-density systems have emerged as a current approach of enhancing the bioavailability and controlled delivery of drugs that exhibit an absorption window. So, oral controlled release and site-specific drug delivery system has been of great interest in the pharmaceutical field to achieve an improved therapeutic advantage. In this review, we have discussed the various approaches to produce gastro retention of drug delivery system, with special discussion on floating in-situ gel system for stomach specific drug delivery. As it offers several...

Multifunctional excipients are class of excipients that includes pre-processed and co-processed excipients that provide added functionalities to the formulation. Functionality is a desirable property of the material that aids manufacturing and improves the quality and performance of the material. This review article reveals with the functionality evaluation of excipients that include surrogate functionality and explicit functionality of excipient. The surrogate functionality gives information that predicts whether or not a particular excipient is likely to have the requisite functionality to produce a product that will meet finished product specifications in all respects. The explicit functionality means the ability of excipient to develop an appropriate formulation of a drug and a useful manufacturing process to create a tablet. Compactibility of excipient is a capability of the material to form coherent agglomerates after compression, has been analyzed by compact density, tensile strength, solid fraction, bonding index, etc. The compatibility mainly depends upon the material property like plastic and...

Proteins interact in the cellular arena to carry out a majority of the vital functions of the cells. After exploring the transcriptome, the researchers are now targeting to investigate the interactome of a cell. This can help to design more efficient drug and vaccine formulations and therapeutic targets benefiting humankind in every possible way. Advancement in protein and protein networking databases gives the first insight to study such macromolecular interactions paving the way for their in-vitro and in-vivo analysis. However, none of the technique can promise 100% efficiency alone due to some limitations like time, cost, and false positive results. Combination of one or more techniques can enhance data quality and reliability. Recent advancements in the studies of the protein-protein interaction using computational methods have led the identification of different signaling pathways and protein complex involved in various specific diseases. However, the major challenge faced is to verify the results obtained from the virtual prediction software’s. In this review, we have focused on how different techniques have been accustomed...
