For a long time, drug delivery systems (DDS) have been targeted to get expected results. With nanotechnology-based DDS, a wide assortment of flawless challenges can be tackled at present. Known as a nanosponge, a nanosponge is a modern division of material consisting of tiny particles that transmit only a few nanometers. The nano-formulations are highly effective for the delivery of low-solubility drugs. Many drugs with narrow therapeutic windows can benefit from improving water solubility. It has even been claimed they can be utilized to target and control delivery. In addition, huge amounts of money have been spent on developing new formulations of the DDS in recent times. Learn how nanosponges are prepared, its advantages, and its disadvantages. Resources were consulted to comprehend recent enhancements and patents in the domain. The ideal DDS has been developed by combining many different formulations; nano sponges are one of them. Analysts have examined them and found that they produce positive results and can improve the stability of poorly water-soluble drugs. The drug will be released at the precise target site when it reaches the body and sticks to the surface of the target site. As medication maximum action declines, it is more difficult to formulate impotent drugs. Considering this, nanosponges are organized and examined to determine whether they are problematic. Nanosponges in drug delivery can be characterized by their characteristics, preparation, factors, and applications. The article was written based on research articles about nanosponges. Data on nanosponges drug delivery systems from the past decade was collected using a factorial design. Study authors report that factor design plays an imperative role in optimizing drug dosage forms. Researchers will save time by reviewing the literature on nanosponges via factorial designs instead of searching for it.

Abstract Low oral bioavailability as a consequence of low water solubility of drugs is a growing challenge to the development of new pharmaceutical products. One of the most popular approaches of oral bioavailability and solubility enhancement is the utilization of lipid-based drug delivery systems. Their use in product development is growing due to the versatility of pharmaceutical lipid excipients and drug formulations, and their compatibility with liquid, semi-solid, and solid dosage forms. Lipid formulations, such as self-emulsifying (SEDDS), self-microemulsifying SMEDDS) and self- -nanoemulsifying drug delivery systems (SNEDDS) were explored in many studies as an efficient approach for improving the bioavailability and dissolution rate of poorly water-soluble drugs. One of the greatest advantages of incorporating poorly soluble drugs into such formulations is their spontaneous emulsification and formation of an emulsion, microemulsion or nanoemulsion in aqueous media. This review article focuses on the following topics. First, it presents a classification overview of lipid-based drug delivery systems and mechanisms involved in improving the solubility and bioavailability of poorly water-soluble drugs. Second, the article reviews components of lipid-based drug delivery systems for oral use with their characteristics. Third, it brings a detailed description of SEDDS, SMEDDS and SNEDDS, which are very often misused in literature, with special emphasis on the comparison between microemulsions and nanoemulsions.

Lipid-based drug delivery systems are extensively reported in literature for enhancing the drug solubility, permeability and bioavailability. These systems include   simple oil solutions, coarse, multiple and dry emulsions, complex self-emulsifying, microemulsifying or nanoemulsifying drug delivery systems. Self-emulsifying systems are further classified as self-microemulsifying drug delivery systems (SMEDDS) and self-nanoemulsifying drug delivery systems (SNEDDS) are most prevailing and commercially viable oil based approach for drugs that exhibit low dissolution rate and inadequate absorption. Ever since the progress of SNEDDS, they drew the interest of researchers in order to deal with the challenges of poorly water-soluble drugs. SNEDDS is a proven method for enhancing solubility and bioavailability of lipophilic compounds. Considering the ease of large-scale production and the robustness of SNEDDS, several formulations techniques are commercially available. The stability of SNEDDS can be further enhanced by solidifying liquid SNEDDS. Controlled release and supersaturated SNEDDS received patient compliance with larger drug loading. Presence of biodegradable ingredients and ‘drug-targeting opportunities’ facilitate SNEDDS a clear merit and distinction amongst available solubility enhancement techniques. In this article attempt was made to present an overview of SNEDDS, their mechanism, formulation excipients and potentials of SNEDDS, recent advancements, advantages and disadvantages of SNEDDS formulations. The article also focuses on reviewing the application of SNEDDS in enhancing bioavailability of antihypertensive drugs.

Ease of administration and painless approach made oral route the most preferred. Poor oral bioavailability is pronounced with the majority of recent active ingredients because of dissolution rate limited absorption. Failure to attain intended therapeutic effect of the poor water soluble drugs by this route led to development of novel drug delivery systems which will fulfill therapeutic needs with minimum dose. Although many formulation approaches like solid dispersions, complexation, pH modification, and cocrystals exist, lipid based delivery systems finding increased appliance with the apparent increase in absorption of drug. Among lipid based formulations, self-microemulsifying formulations (droplet size < 100 nm) are evident to improve the oral bioavailability of hydrophobic drugs primarily due to their efficiency in facilitating solubilization and in presenting the hydrophobic drug in solubilized form whereby dissolution process can be circumvented. Various components that are used to formulate these dosage forms like surfactants and lipids contribute to the overall improvement in oral bioavailability via promoting the lymphatic transport; thereby hepatic first pass metabolism can be surmounted. The present paper gives exhaustive information on the formulation design and characterization of SMEDDS along with the probable mechanisms by which the bioavailability can be improved with SMEDDS.

Principle Objective

The principle objective of formulation of lipid-based drugs is to enhance their bioavailability. The use of lipids in drug delivery is no more a new trend now but is still the promising concept. Lipid-based drug delivery systems (LBDDS) are one of the emerging technologies designed to address challenges like the solubility and bioavailability of poorly water-soluble drugs. Lipid-based formulations can be tailored to meet a wide range of product requirements dictated by disease indication, route of administration, cost consideration, product stability, toxicity, and efficacy. These formulations are also a commercially viable strategy to formulate pharmaceuticals, for topical, oral, pulmonary, or parenteral delivery. In addition, lipid-based formulations have been shown to reduce the toxicity of various drugs by changing the biodistribution of the drug away from sensitive organs. However, the number of applications for lipid-based formulations has expanded as the nature and type of active drugs under investigation have become more varied. This paper mainly focuses on novel lipid-based formulations, namely, emulsions, vesicular systems, and lipid particulate systems and their subcategories as well as on their prominent applications in pharmaceutical drug delivery.
