There is considerable interest in the skin as a site of drug application for both local and systemic effect. However, the skin, in particular the stratum corneum, possesses a formidable barrier to drug penetration thereby limiting topical and transdermal bioavailability. Skin penetration enhancement techniques have been developed to improve bioavailability and to increase the range of drugs for which topical and transdermal delivery is a viable option. The permeation of drug through skin can be enhanced by both chemical penetration enhancement and physical methods. In this review, we have discussed the physical and chemical penetration enhancement technology for transdermal drug delivery as well as the probable mechanisms of action.

Objective: Malaria is the deadliest infectious diseases affecting millions of people worldwide. Several strategies have been under extensive research since decades including chemoprophylaxis and other disease antimalarial interventions like malaria vaccine. The vaccine development is more difficult to predict than drug development and presents a unique challenge as already there has been no vaccine effective against a parasite. For development and screening of malaria vaccine, a suitable animal model is the prime requirement. Non-human primate models are considerably a good choice to mimic human malarias, but due to various reasons like ethical, cost effective, maintenance and relative ease of conducting experiments. Rodent’s malaria vaccination models remain the preferred choice.Methods: To develop such model we required 100% lethal host/parasite system that would be an ideal system for experimental vaccination studies. Such a rigorous model is particularly required for the identification and development of suitable adjuvant/co-adjuvant(s) for future human malaria vaccines.Results: Because, P. yoelii nigeriensis invariably causes a 100% lethal fulminating infection in Swiss mice, so in present studies, we vaccinate Swiss mice with P. yoelii nigeriensis total P. yoelii nigeriensis - Soluble antigen (Pyn-SA)and saponin as adjuvant, following 100% lethal study homologous challenge and then followed by passive transfer of experiment.Conclusion: P. yoelii nigeriensis caused a fulminant 100% lethal infection in mice (as saw in the control groups). The protection observed in the vaccinated group of mice can be unambiguously ascribed to vaccine-induced protective immunity only. © 2014, IJPPS. All rights reserved.

Background Increase in expression of eIF4E (Eukaryotic translation initiation factor 4E) protein is mediated by oncogenic proteins of Human Papilloma Virus (HPV). Increased expression of eIF4E plays an important role in HPV induced carcinogenesis. Ribavirin and Indinavir are known inhibitors of eIF4E activity. Methods The effect of the drugs on HeLa cells was assessed by in vitro assays including cell viability using MTT and Neutral red assay, apoptotic potential using Caspase-3, Caspase-8 and Caspase-9 activity assays and MMP-2 and MMP-9 secretion by determination of Gelatinase activity. The in vivo effect of Ribavirin treatment on tumor volume was assessed in human xenograft in immunocompromised C57BL/6 mice. Results In vitro analyses indicate that Ribavirin and Indinavir reduce viability of HeLa cells, induce apoptosis and decrease secretion of MMPs. Treatment with Ribavirin at a dose of 50 mg/kg and 100 mg/kg daily led to significant decrease in tumor volume in vivo. Conclusion The study thus provides evidence that Ribavirin and Indinavir can be explored as therapy against HPV-18 induced cervical cancer. © 2016 Institute of Pharmacology, Polish Academy of Sciences

Systemic drug delivery in schizophrenia is a major challenge due to presence of obstacles like, blood-brain barrier and P-glycoprotein, which prohibit entry of drugs into the brain. Quetiapine fumarate (QF), a substrate to P-glycoprotein under goes extensive first pass metabolism leading to limited absorption thus necessitating frequent oral administration. The aim of this study was to develop QF based microemulsion (ME) with and without chitosan (CH) to investigate its potential use in improving the bioavailability and brain targeting efficiency following non-invasive intranasal administration. QF loaded ME and mucoadhesive ME (MME) showed globule size, pH and viscosity in the range of 29–47 nm, 5.5–6.5 and 17–40 cP respectively. CH-ME with spherical globules having mean size of 35.31 ± 1.71 nm, pH value of 5.61 ± 0.16 showed highest ex-vivo nasal diffusion (78.26 ± 3.29%) in 8 h with no sign of structural damage upon histopathological examination. Circular plume with an ovality ratio closer to 1.3 for CH-ME depicted ideal spray pattern. Significantly higher brain/blood ratio of CH-ME in comparison to QF-ME and drug solution following intranasal administration revealed prolonged retention of QF at site of action suggesting superiority of CH as permeability enhancer. Following intranasal administration, 2.7 and 3.8 folds higher nasal bioavailability in brain with CH-ME compared to QF-ME and drug solution respectively is indicative of preferential nose to brain transport (80.51 ± 6.46%) bypassing blood-brain barrier. Overall, the above finding shows promising results in the area of developing non-invasive intranasal route as an alternative to oral route for brain delivery. © 2016 Elsevier B.V.

In the present investigation, Quality by Design (QbD) approach was applied on the development and optimization of solid lipid nanoparticle (SLN) formulation of hydrophilic drug rivastigmine (RHT). RHT SLN were formulated by homogenization and ultrasonication method using Compritol 888 ATO, tween-80 and poloxamer-188 as lipid, surfactant and stabilizer respectively. The effect of independent variables (X1 - drug: lipid ratio, X2 - surfactant concentration and X3 - homogenization time) on quality attributes of SLN i.e. dependent variables (Y1 - size, Y2 - PDI and Y3 - %entrapment efficiency (%EE)) were investigated using 33 factorial design. Multiple linear regression analysis and ANOVA were employed to indentify and estimate the main effect, 2FI, quadratic and cubic effect. Optimized RHT SLN formula was derived from an overlay plot on which further effect of probe sonication was evaluated. Final RHT SLN showed narrow size distribution (PDI- 0.132 ± 0.016) with particle size of 82.5 ± 4.07 nm and %EE of 66.84 ± 2.49. DSC and XRD study showed incorporation of RHT into imperfect crystal lattice of Compritol 888 ATO. In comparison to RHT solution, RHT SLN showed higher in-vitro and ex-vivo diffusion. The diffusion followed Higuchi model indicating drug diffusion from the lipid matrix due to erosion. Histopathology study showed intact nasal mucosa with RHT SLN indicating safety of RHT SLN for intranasal administration. © 2015 Elsevier B.V. All rights reserved.

Objective: To investigate the gastroprotective activity of hydroalcoholic extract leaves of Ficus religiosa (F. religiosa) in different experimental models of gastric ulcer in rats. Methods: The hydroalcoholic extract leaves of F. religiosa were studied at two dose levels (250 and 500 mg/kg, oral) in rats against absolute ethanol (0.2 mL oral), aspirin (200 mg/kg) and pyloric ligation induced gastric ulcer. Ranitidine (50 mg/kg, oral) was used as a standard drug. Mean ulcer indices and oxidative stress were measured. Phytochemical tests and acute toxicity tests were also carried out. Results: Administration of F. religiosa to rats significantly decreased the ulcer index value when compared with the control treated group. Ranitidine (50 mg/kg, oral) also produced a significant decrease the ulcer index value when compared with the control treated group. Phytochemical analysis revealed the presence of tannins, sterols, saponins, flavonoids, carbohydrates and proteins. Conclusions: The results suggest that the leaves of the F. religiosa possess significant anti ulcer activity. © 2010 Hainan Medical College.

This study aims to evaluate the impact of surface area of silica particles on in vitro release of poorly soluble drug aceclofenac and their in vivo performances. Mesoporous silicas of different surface area and porosity were synthesized and characterized. Aceclofenac loaded silicas were prepared by solvent evaporation technique and characterized for surface area, pore size, DSC, FTIR and p-XRD. The dissolution efficiency (DE) of the mesoporous and nonporous silica was ∼2 times more than that of plain drug and marketed tablets in acidic discriminating media. A significant enhancement of 189% and 164% in oral bioavailability (AUC0-8) was observed for optimized aceclofenac loaded mesoporous formulation (MS11/72) and nonporous silica (NP), respectively, when compared to plain aceclofenac in male Wistar rats. However, no correlation could be established between the enhancements in their oral bioavailability and their corresponding surface area. The surface area of MS11/72 was 5 times more (∼1011 m2/g) when compared to NP (∼200 m2/g) and the enhancement in the oral bioavailability was only 1.15 times. This could be due to the limiting value of effective surface area of the drug available for in vitro dissolution beyond which, any further increase in surface area fails to improve the release rate or its bioavailability. © 2013 Elsevier B.V.

Purpose: A new, injectable, drug-loaded composite graft was developed to enable infection free wound healing. Methods: The graft was fabricated using gentamicin and biomimetic microparticulate scaffolds in gelatin gel and characterized for biologically relevant properties like fluid uptake, evaporative water loss (EWL), water vapor transmission rate (WVTR), Young's modulus and degradation. It was evaluated for drug release, cytocompatibility and antimicrobial efficacy against Staphylococcus aureus and Pseudomonas aeruginosa. Results: Graft exhibited fluid uptake of 13.79%, EWL of 60-70% in 10 h, WVTR of 5480.31 g/m2/d, and Young's modulus as 2.1-10.8 kPa. It exhibited 99.36% degree of crosslinking and a dual degradation behavior wherein, the carrier gel, gelatin, degraded rapidly leaving the microparticulate scaffolds intact. Drug release studies showed a sustained release of gentamicin for 13 days sufficient to inhibit the infection at the wound site. Cytocompatibility assessment of the graft revealed that graft supported cell adhesion, proliferation and migration. The antibacterial efficacy of the graft was assessed using Kirby-Bauer method and time kill assay, wherein results indicated a quick, effective (≥5-log reduction in CFU/ml) and long lasting antimicrobial effect. Conclusions: These results as a whole indicate that the graft represents an effective alternative for infection-free healing of full thickness wounds.

The study was carried out to investigate the anti-obesity effects of Aegle marmelos leaves extracts and its phytochemical constituents in vitro and in vivo. The dichloromethane (DCM), ethyl acetate (EtOAc) and n-butanol extracts of A. marmelos leaves were studied for their lipolytic effect. Lipolysis was measured by determining the amount of glycerol released at 12 h and 24 h at 50 μg/ml and 100 μg/ml concentrations. Phytochemical investigation of the most active DCM extract yielded 14 compounds. The isolated compounds were evaluated for their lipolytic effects at 50 μM and 100 μM. The most active compounds, umbelliferone and esculetin were further screened for their antiobesity effects in vivo in the high fat diet (HFD) induced obese rat model. Umbelliferone and esculetin reduced body weight, total triglyceride (TG), total cholesterol (TC) and glucose level in their respective HFD groups. A. marmelos DCM extract and compounds isolated from it have the potential of counteracting the obesity by lipolysis in adipocytes. © 2013 Elsevier GmbH. All rights reserved.
