OBJECTIVE: Curcumin exhibits many beneficial health-promoting characteristics. However, its poor oral absorption precludes its general use. This study assessed the bioavailability of a novel curcumin formulation compared to 95% curcumin and published results for various other curcumin formulations. METHODS: A randomized, crossover, double-blind, comparator-controlled pharmacokinetic study was performed in 12 healthy adult subjects to determine the appearance of free curcumin and its metabolites curcumin sulfate and curcumin glucuronide in plasma after a single dose of a novel proprietary curcumin liquid droplet micromicellar formulation (CLDM) and unformulated 95% curcumin powder in capsule form...

Curcuminoids are the major bioactive molecules in turmeric, and poor bioavailability deters them from being the major components of many health and wellness applications. This study was conducted to assess the bioavailability of a completely natural turmeric matrix formulation (CNTMF) and compare its bioavailability with two other commercially available formulations, namely, curcumin with volatile oil (volatile oil formulation) and curcumin with phospholipids and cellulose (phospholipid formulation) in healthy human adult male subjects (15 each group) under fasting conditions...

Parkinson's disease (PD) pathology is characterized by the abnormal accumulation and aggregation of the pre-synaptic protein α-synuclein in the dopaminergic neurons as Lewy bodies (LBs). Curcumin, which plays a neuroprotective role in various animal models of PD, was found to directly modulate the aggregation of α-synuclein in in vitro as well as in in vivo studies. While curcumin has been shown to exhibit strong anti-oxidant and anti-inflammatory properties, there are a number of other possible mechanisms by which curcumin may alter α-synuclein aggregation which still remains obscure...

Amorphization has been widely recognized as a useful solubilization technique for poorly water-soluble drugs, such as curcumin. We have recently reported the novel finding that the membrane transport of curcumin was markedly enhanced when amorphous solid particles of curcumin came into direct contact with the lipid membrane surface, but this was not true for crystalline solid particles. The increase in the permeation of curcumin was found to be independent of the improvements in aqueous solubility brought about by amorphization...

A supersaturatable self-microemulsifying drug delivery system (S-SMEDDS) with a reduced amount of surfactant and incorporation of a polymer precipitation inhibitor, Eudragit® E PO was developed. The optimized S-SMEDDS formulation (SS-15) consisted of 55% surfactants, 40% oils, and 5% Eudragit® E PO (curcumin at 44.4 mg/g of the formulation). The precipitation profiles from the supersaturation assay revealed that the curcumin S-SMEDDS performed as a better inhibitor of curcumin precipitation in simulated gastric fluid over a 240-min study than the normal curcumin SMEDDS and an aqueous curcumin suspension...

The potential application of curcumin was heavily limited in biomedicine because of its poor solubility in pure water. To circumvent the detracting feature, two novel water-soluble amino acid modified curcumin derivatives (MLC and DLC) have been synthesized through the condensation reaction between curcumin and N(α)-Fmoc-N(ε)-Boc-l-lysine. Benefiting from the enhanced solubility of 3.32×10(-2)g/mL for MLC and 4.66×10(-2)g/mL for DLC, the inhibition effects of the as-prepared derivatives on the amyloid fibrillation of lysozyme (HEWL) were investigated detaily in water solution...

Mesoporous silica particles have recently been used in the preparation of solid oral as well as dermal pharmaceutical formulations. In this work, the use of mesoporous silica of different particle size, pore size and pore volume as carrier for curcumin in hydrogels for dermal use was investigated. Oil absorption capacity of the silica, in vitro release of curcumin from formulations and chemical stability of curcumin during three months storage were evaluated. It was found that the silica particles did not alter in vitro release of curcumin compared to an emulsion...

In order to realize a combination of chemotherapy and selective drug release into tumor cells, novel pH-sensitive prodrugnanoparticles were designed and prepared via the self-assembly of a synthetic amphiphilic macromolecular prodrug for the selective co-delivery of doxorubicin (Dox) and curcumin (Cur). Dox was covalently conjugated to the oxidized sodium alginate through a Schiff base reaction to produce an amphiphilic macromolecular prodrug, and the prodrug was subsequently self-assembled into nanoparticles (Dox-NPs) in an aqueous solution, which were responsive to the acidic environment in tumor cells...

Curcumin was found to be beneficial in treating several skin pathologies and diseases, providing antioxidant protection due to its reducing properties and its electrophilic properties (the ability to activate the Nrf2 pathway and induce phase II cytoprotective enzymes). Nevertheless, clinical applications of curcumin are being hampered by its insufficient solubility, chemical instability, and poor absorption, leading to low efficacy in preventing skin pathologies. These limitations can be overcome by using a nanotechnology-based delivery system...

The lipophilic phytocannabinoids cannabidiol (CBD) and Δ(9)-tetrahydrocannabinol (THC) show therapeutic efficacy in various medical conditions. Both molecules are poorly water soluble and subjected to extensive first pass metabolism in the gastrointestinal tract, leading to a limited oral bioavailability of approximately 9%. We have developed an advanced lipid based Self-Emulsifying Drug Delivery System termed Advanced Pro-NanoLiposphere (PNL) pre-concentrate. The PNL is composed of lipid and emulsifying excipients of GRAS status and are known to increase solubility and reduce Phase I metabolism of lipophilic active compounds...

An advanced oral drug delivery system that can effectively deliver drugs with poor oral bioavailability is strongly desirable. Herein, a multifunctional nano-in-micro structured composite is developed by encapsulation of the mucoadhesive poly(methyl vinyl ether-co-maleic acid) modified halloysite nanotubes (HNTs) with the pH-responsive hydroxypropyl methylcellulose acetate succinate by the microfluidics to control the drug release, increase cell-particle interaction, and improve drug absorption. The microparticles show spherical shape, homogeneous particle size distribution (58 ± 1 µm), and pH-responsive dissolution behavior at pH > 6, and they prevent the premature release of curcumin in simulated pH conditions of the stomach and immediately release the curcumin in simulated pH conditions of the small intestine...

Curcumin, the bioactive component of turmeric also known as "Indian Yellow Gold," exhibits therapeutic efficacy against several chronic inflammatory and infectious diseases. Even though considered as a wonder drug pertaining to a myriad of reported benefits, the translational potential of curcumin is limited by its low systemic bioavailability due to its poor intestinal absorption, rapid metabolism, and rapid systemic elimination. Therefore, the translational potential of this compound is specifically challenged by bioavailability issues, and several laboratories are making efforts to improve its bioavailability...

Oxidative damage and inflammation have been identified, through clinical and preclinical studies, as the main causes of nonhealing chronic wounds. Reduction of persistent chronic inflammation by application of antioxidant and anti-inflammatory agents such as curcumin has been well studied. However, low aqueous solubility, poor tissue absorption, rapid metabolism and short plasma half-life have made curcumin unsuitable for systemic administration for better wound healing. Recently, various topical formulations of curcumin such as films, fibers, emulsion, hydrogels and different nanoformulations have been developed for targeted delivery of curcumin at wounded sites...

Deltamethrin (DLM) is a well-known pyrethroid insecticide which is widely used in the agriculture and home pest control due to restriction on the sale of organophosphate. DLM induced apoptosis is well known but its mechanism is still unclear. This study has been designed to find out its mechanism of apoptosis with the help of computational methods along with in vivo methods. The QikProp and ProTox results have shown that DLM has good oral absorption. The docking results reveal that DLM has a strong binding affinity toward the CD4, CD8, CD28 and CD45 receptors...

Many types of bioactive molecules found in foods ("nutraceuticals") have been shown to exert anticancer activities, including curcumin, resveratrol, polyphenols, sulforaphane, anthocyanins, genistein, quercetin and lycopene. The potential health benefits of nutraceuticals are often not realized because of their poor water solubility, chemical instability, adverse taste profile, and low oral bioavailability. Carefully designed food matrices are being developed to overcome these problems. Nutraceuticals can be isolated from their natural environment, and then incorporated into functional foods, often with the help of delivery systems (such as emulsions, nanoemulsions, liposomes, biopolymer nanoparticles, and microgels)...
