This article describes current strategies to enhance aqueous solubility and dissolution rate of poor soluble drugs. Most drugs in the market are lipophilic with low or poor water solubility. There are various methods to enhance solubility: co-solvency, particle size reduction, salt formation and Self Nanoemulsifying drug delivery systems, SEDDS is a novel approach to enhance solubility, dissolution rate and bioavailability of drugs. The study involves formulation and evaluation of solid self-Nano emulsifying drug delivery system (S-SNEDDS) to enhance aqueous solubility and dissolution rate. Oral route is the most convenient route for non-invasive administration. S-SNEDDS has more advantages when compared to the liquid self-emulsifying drug delivery system. Excipients were selected depends upon the drug compatibility oils, surfactants and co surfactants were selected to formulate Liquid SNEDDS these formulated liquid self-nano emulsifying drug delivery system converted into solid by the help of porous carriers, Melted binder or with the help of drying process. Conversion process of liquid to solid involves various techniques; they are spray drying; freeze drying and fluid bed coating technique; extrusion, melting granulation technique. Liquid SNEDDS has a high ability to improve dissolution and solubility of drugs but it also has disadvantages like incompatibility, decreased drug loading, shorter shelf life, ease of manufacturing and ability to deliver peptides that are prone to enzymatic hydrolysis.

Pass Metabolism

In the recent days about 75% of the drugs taken orally are does not show the desired therapeutic effect. Oral conventional dosage forms have several disadvantages such as poor bioavailability due to hepatic first pass metabolism and tendency to produce rapid blood level spikes (Both high and low). Thus, rapid drug levels in the plasma leads to a need of high and/or frequent dosing, which can be both uneconomical and inconvenient. To overcome such disadvantages transdermal drug delivery system was developed. TDDS is such a delivery system which has been explored extensively over the last two decades, with therapeutic success. Transdermal drug delivery systems (TDDS) are the drug delivery systems which involves transportation of drug to epidermal and dermal tissues of the skin for local therapeutic action while major fraction of the drug is transported into the systemic blood circulation. Topical administration of therapeutic agents offers vast advantages over conventional oral and invasive methods of drug delivery. Some of the advantages of transdermal drug delivery include limitation of hepatic first pass metabolism, enhancement of therapeutic efficiency and maintenance of steady state plasma level concentration of the drug. This study includes a brief overview of TDDS, its advantages over conventional dosage forms, drug delivery routes across human skin, permeation enhancers, and classification, formulation, methods of preparation and evaluation of transdermal patches.

Microsponges (MSPs) are at the forefront of the rapidly developing field of novel drug delivery systems which are gaining popularity due to their use for controlled release and targeted drug delivery. The microsponge delivery system (MDS) is a patented polymeric system consisting of porous microspheres typically 10-25 microns in diameter, loaded with an active agent. They are tiny sponge-like spherical particles that consist of a myriad of interconnecting voids within a non-collapsible structure with a large porous surface through which active ingredient is released in a controlled manner. Microsponge also hold a certification as one of the potential approaches for gastric retention where many oral dosage forms face several physiological restrictions due to non-uniform absorption pattern, inadequate medication release and shorter residence time in the stomach. This type of drug delivery system which is non-irritating, non-allergic, non-toxic, can suspend or entrap a wide variety of substances, and can then be incorporated into a formulated product such as gel, cream, liquid or powder that is why it is called as a “versatile drug delivery system”. It overcomes the drawbacks of other formulations such as frequency of dosing, drug reaction, incompatibility with environmental condition. These porous microspheres were exclusively designed for chronotherapeutic topical drug delivery but attempt to utilize them for oral, pulmonary and parenteral drug delivery were also made. The present review elaborates about the multifunctional microsponge technology including its preparation, characterization, evaluation methods along with recent research and future potential.

AbstractNanoparticles as drug delivery systems can alter the drugs' hydrophilicity to affect drug uptake and efflux in tissues. They prevent drugs from non-specifically binding with bio-macromolecules and enhance drug accumulation at the lesion sites, improving therapy effects and reducing unnecessary side effects. Metal–organic frameworks (MOFs), the typical nanoparticles, a class of crystalline porous materials via self-assembled organic linkers and metal ions, exhibit excellent biodegradability, pore shape and sizes, and finely tunable chemical composition. MOFs have a rigid molecular structure, and tunable pore size can improve the encapsulation drug's stability under harsh conditions. Besides, the surface of MOFs can be modified with small-molecule ligands and biomolecule, and binding with the biomarkers which is overexpressed on the surface of cancer cells. MOFs formulations for therapeutic have been developed to effectively respond to the unique tumor microenvironment (TEM), such as high H2O2 levels, hypoxia, and high concentration glutathione (GSH). Thus, MOFs as a drug delivery system should avoid drugs leaking during blood circulation and releasing at the lesion sites via a controlling manner. In this article, we will summary environment responsive MOFs as drug delivery systems for tumor therapy under different stimuli.

General Method

Nanoparticulate drug delivery system are the rapidly developing system, and nanoparticles are present in the size range of 1-100nm. Nanoparticles composed of various thermal, electrical, and optical property. Nanoparticles offers the potential advantages over the traditional dosage forms it is ascribable to the properties of nanoparticles. Nanoparticulate drug delivery system ensures the site-specific delivery of a drug(Targeting drug delivery) and aids in improving the efficacy of the new as well as old drugs and has the potential in crossing the various physiological barriers and also improves the therapeutic index of the drugs and increases the patient compliance. The objectives of this review is to classify the nanoparticles based on the different groups, surface properties of nanoparticles, describe the strategies of drug targeting, the necessity of nanoparticles their general method of preparation, different methods used in characterization, self- assembly and mechanism of drug release in a systemic manner.
