Oral films, a promising novel drug delivery system, are a strip of single or multilayered, mucoadhesive or non-mucoadhesive, thin polymeric films that are intended to deliver active therapeutic moieties either locally or systemically in oral cavity through sublingual, buccal, palatal, or gastrointestinal absorption [1-3]. In general, films are known by several names including but not limited to...

The growing demand for rayon and cellulosic products has resulted in the conversion of a number of kraft pulp mills into dissolving pulp mills in recent years. In fact, kraft-based dissolving pulp production fits well into the concept of an integrated forest biorefinery, in particular, the utilization of dissolved organics in the pre-hydrolysis liquor (PHL) for bio-materials and bio-energy purp...

San Carlos forsterite was dissolved in initially pure H2O in a batch reactor in contact with the atmosphere for five years. The reactive fluid aqueous pH remained relatively stable at pH 6.7 throughout the experiment. Aqueous Mg concentration maximized after approximately two years time at 3x10 mol/kg, whereas aqueous Si concentrations increased continuously with time, reaching 2x10 mol/kg afte...

A series of polyvinylpyrrolidone fibers loaded with paracetamol (PCM) and caffeine (CAF) was fabricated by electrospinning and explored as potential oral fast-dissolving films. The fibers take the form of uniform cylinders with smooth surfaces, and contain the drugs in the amorphous form. Drug-polymer intermolecular interactions were evidenced by infrared spectroscopy and molecular modeling. Th...

Sildenafil citrate is one of the most effective agents for treatment of erectile dysfunction which acts by inhibiting the cGMP-specific phosphodiesterase type 5. Extensive research work is focused on flash release dosage forms and especially fast dissolving films are successful to attract pharma-industry due to ease of preparation and opportunity to extend patent life. Films are widely acceptab...

The intention of present research is to formulate and develop the meclizine hydrochloride fast dissolving tablets using sublimation method to enhance the dissolution rate. In this study an attempt was made to fasten the drug release from the oral tablets by incorporating the superdisintegrants and camphor as sublimating agent. The prepared fast dissolving tablets were subjected to precompressio...

In the present work, Flunarizine hydrochloride, an anti-migraine drug has been formulated into fast dissolving tablets by sublimation method using camphor and menthol as sublimating agents and treated agar as superdisintegrant. Concentrations of the sublimating agents were varied keeping the concentration of superdisintegrant fixed. The aim of the study was to prepare fast dissolving tablets wi...

Dissolving microneedle patches offer promise as a simple, minimally invasive method of drug and vaccine delivery to the skin that avoids the need for hypodermic needles. However, it can be difficult to control the amount and localization of drug within microneedles. In this study, we developed novel microneedle designs to improve control of drug encapsulation and delivery using dissolving micro...

A Ni–Pt alloy porous layer was formed by electrodepositing Pt using Ni as the substrate sample, followed Al-depositing and Al-dissolving. The electrolyzed an aqueous solution medium, Al-dissolving were treated a molten salt medium. used NaCl–KCl with 3.5 mol% AlF3 added. It found that electrodeposition on surface had finer structure. Furthermore, it clarified lower potential, thicker Ni-Pt laye...

Asphaltene precipitation occurs in petroleum fluids under certain unfavorable conditions, but can be controlled by tuning composition. Aromatic solvents in large quantities can prevent precipitation entirely and can dissolve already precipitated asphaltenes. Some polymeric surfactants can dissolve asphaltenes when added at much lower concentrations than required by aromatic solvents. Other disp...
