In an attempt to improve the low oral bioavailability of Diacerein (DCN), the combination of a ternary solid dispersion and an asymmetric osmotic pump system had been designed to enhance solubility and to control DCN delivery. Ternary DCN solid dispersion was prepared by melting fusion method using surfactant polymers, and carrier (Pluronic® PF127, Solutol® HS15, and PEG 35K) and this DCN solid dispersion powder with the proper amount of excipients were compressed and coated with Opadry® CA to develop a Semi-Permeable and Asymmetric Osmotic Pump tablets...

In The present project, a variety of MnFe2 O4 (Mn) and Cr2 Fe6 O12 (Cr)-based nanocarriers (NCs) were synthesized as photosensitizer and NCs for delivery of chemotherapeutic curcumin (CUR) and provide a new structure for Photodynamic Therapy (PDT). For determining efficiency of NCs release study, MTT assay, lethal dose test and hemolysis assay were carried out. The release study showed the release of CUR from NCs was pH-dependent, but, every NCs had its own behavior for releasing the drug. The data acquired from the release study showed the CUR release from Mn can reach to over 90% at acidic media instead of 41% at neutral media...

The purpose of this study was to investigate the nasal absorption rate and nasal mucosal toxicity of thermosensitive ketamine in situ gels containing various absorption enhancers. The optimal composition ratio for the gel matrix was determined to be 17.2% Poloxamer 407 and 2% Poloxamer 188, as this combination resulted in solutions with a gelation point within the range found in the nasal cavity. Ketamine gels containing the tested enhancers, namely ethylenediaminetetraacetic acid disodium salt, hydroxypropyl-β-cyclodextrin, propylene glycol, or Tween-80, were compared with enhancer-free counterparts to determine the absorption of the drug, in vivo by measuring its plasma levels in rats and in vitro using a Franz diffusion cell...

It is estimated that 80% of the world's population consumes caffeine from beverages and food every day. The traditional form of caffeine intake is oral, but more recently people have been inhaling caffeine using nasal sprays. However, the effects of caffeine inhalation are not well understood. The purpose of this study was to determine whether caffeine inhalation affects mouse behavior. To test this, we compared spontaneous activity of mice following inhalation and intraperitoneal administration of caffeine...

We studied three lactose-based formulations in terms of bulk powder properties and capsule-filling behavior in a tamping pin capsule filling system, to which several mechanical adaptions were made for process optimization in light of future continuous production. The model formulations were thoroughly characterized and filled into size 1 capsules according a well-defined design of experiments (DoE). Overall, the three entirely different formulations were successfully filled within the selected design space...

The aim of present study is to develop Darunavir pro-liposome powder for oral delivery. Darunavir-loaded oral pro-liposome powder (OPP) was prepared by a solvent evaporation technique with varying independent variables at three different levels. Based on different levels pro-liposome powder formulation was optimized by using Box-Behnken design. The formulations were analyzed for its size distribution, entrapment efficiency and surface morphology. Optimized pro-liposome batch A was evaluated for physical parameter, morphological parameters, entrapment efficiency, followed by in vitro, ex- vivo and in-vivo studies...

Objective: Glaucoma is a leading cause of irreversible blindness worldwide. Whereas latanoprost is one of the most effective drugs in glaucoma treatment, its eye drops need frequent application leading to lack of patient adherence. This study aimed to develop a patient-friendly niosome-in-gel system for the sustained ocular delivery of latanoprost. Methods: Niosomes were prepared by the reverse-phase evaporation technique and optimized for different formulation parameters, such as cholesterol/surfactant and drug/surfactant ratios...

Ondansetron HCl is a (5-HT3) serotonin receptor antagonist, used as anti-emetic drug in combination with anticancer agents. Conventional dosage forms have poor bioavailability and patient compliance. These problems can be reduced by the use of nasal niosomal thermo reversible in situ gelling system; Niosomes were formulated using various surfactants (Span 60, Span 80, Tween 20 and Tween 80) in different ratios using thin film hydration technique. Niosomes were evaluated for particle size, zeta potential, Transmission Electron Microscopy (TEM) imaging, drug entrapment efficiency and in-vitro drug release...

Even so, the metal nanoparticles (Metal NPs) have attractive optical and biomedical applications, the translation of metal NPs into the clinical practice remains a challenge due to their severe accumulation in the body. Active targeting to renal podocytes opens the door for enhancing kidney targeting and clearance. The goal of this study was to asses the excretion of larger particle size through kidney podocyte via active targeting. To reach this goal, PEGylated quantum dots (QDs) were coated with vapreotide (VAP) for selectively reaching somatostatin receptors (sstrs) expressed in the podocyte...

Objectives: L-Glutathione (GSH) is an endogenous tripeptide with super antioxidant properties. In this study, preformulation parameters of GSH and its degradation products were fully investigated. Significance: To date, no experimental preformulation data is available for GSH. Therefore, to the author's knowledge, this is the first study to experimentally determine the preformulation parameters of GSH, which can be considered more reliable for further studies. Methods: An HPLC method for GSH was optimized and validated to accurately quantify the GSH amount in solution, used to investigate GSH's solubility and Log P...

Linear and star-like redox-sensitive amphiphilic block copolymers have been studied as anticancer drug delivery systems. However, few reports directly compared the properties of those two structures especially when they are used as nanocarriers for antitumor drugs. To address this, a novel star-like copolymer and its linear counterpart were synthesized with a hydrophobic/redox-responsive/hydrophilic structure. The overall molecular weight of the star-shaped copolymer was nearly equal to that of the linear counterpart...

Soluble Microneedles (MNs) of four different hydrophilic polymers namely Sodium Carboxymethyl Cellulose ( CMC), Polyvinylpyrrolidone (PVP) K30, PVP K90 and Sodium Hyaluronate (HU) were fabricated by mold casting technique. When exposed to gamma radiation, a dose of 25 Kilogray (kGy) was found to render the microneedle (MN) sterile. However, CMC was found to form MN with poor mechanical properties whereas PVP K30 MNs were drastically deformed upon exposure to applied dose as observed in bright field microscopy...
