Pharmacokinetic and pharmacodynamic evaluation of Solid self-nanoemulsifying delivery system (SSNEDDS) loaded with curcumin and duloxetine in attenuation of neuropathic pain in rats.

The present investigation is focused on improving oral bioavailability of poorly soluble and lipophilic drugs, curcumin (CRM) and duloxetine (DXH), through the solid self-nanoemulsifying drug delivery system (S-SNEDDS) and identifying their potential against attenuation of NP in chronic constriction injury (CCI)-induced rats through the solid self-nanoemulsifying drug delivery system (S-SNEDDS). The optimized batch of S-SNEDDS reported was containing CRM and DXH (30 mg each), castor oil (20% w/w), tween-80 (40% w/w), transcutol-P (40% w/w), and syloid 244 FP (1 g). The high dose of each of naïve CRM (NCH), naïve DXH (NDH), physical mixture of DXH and CRM (C-NCM-DXH), S-SNEDDS-CRM (SCH), S-SNEDDS-DXH (SDH), and S-SNEDDS-CRM-DXH (C-SCH-SDH) was subjected for MTT assay.

Flavonoids as Potential Therapeutic Agents for the Management of Diabetic Neuropathy.

Flavonoids are secondary metabolites that are widely distributed in plants. These phenolic compounds are classified into various subgroups based on their structures: flavones, flavonols, isoflavones, flavanones, and anthocyanins. They are known to perform various pharmacological actions like antioxidant, anti-inflammatory, anticancer, antimicrobial, antidiabetic and antiallergic, etc.

Comparison of sildenafil, fluoxetine and its co-administration against chronic constriction injury induced neuropathic pain in rats: An influential additive effect.

Current drug treatment available for neuropathic pain (NP) provides meager and partial pain relief due to incomplete efficacy and dose-dependent adverse effect. Hence, combination therapy can provide prolongation in analgesic effect with milder side effects. The present investigation aimed at observing the effects of sildenafil (SD) on Fluoxetine (FLX) in attenuation of chronic constriction injury (CCI) induced NP in rats.

A three-pronged formulation approach to improve oral bioavailability and therapeutic efficacy of two lipophilic drugs with gastric lability.

The aim of present study was to co-administer curcumin (CRM) liquisolid pellets and coated duloxetine hydrochloride (DXH) pellets in rats to treat neuropathic pain (NP) associated with chronic constriction injury (CCI). To formulate liquisolid pellets of CRM, it was first dissolved in Tween-80 and then adsorbed on the porous surface of MCC PH102 and Syloid XDP that were used as carrier and coating materials, respectively. Central composite design was used to optimize the liquisolid formulation.

Solidification of liquid Modified Apple Polysaccharide by its adsorption on solid porous carriers through spray drying and evaluation of its potential as binding agent for tablets.

In the present study application of Modified Apple Polysaccharide (MAP) as tablet binder was evaluated. Liquid MAP was extracted from apple and solidified by adsorbing it on porous surface of Aerosil-200 and trehalose and this dispersion was dried using spray dryer. The concentration of excipients as well as spray drying conditions was optimised by using Box Behnken Design to achieve desirable powder characteristics.
