Using a strain-controlled rheometer, rhelogical characterization of carbopol 940 has been made in steady shear and start-up flow fields. In this study, aqueous carbopol 940 solutions with different concentrations were used to provide a fundamental information in application of pharmaceutical and cosmetic areas.

Sustained release tablets of Diclofenac Sodium were fabricated using Cashew nut tree gum, HPMC and Carbopol . The tablets were evaluated for preformulation studies like angle of repose, bluk density, compressibility index and physical characteristics like hardness, weight variation, fraibilty and drug content. In-vitro release of drug was performed in PBS pH 7.2 for twelve hours. All the physic...

The aim of this study was to investigate the effects of polyacrylic acid polymers (Ultrez 10, Ultrez 20, Carbopol 980, and Carbopol 940) on the viscosity and the in vitro permeation of phenolic compounds from the gel prepared from natural horse chestnut seed extract. Experiments were performed in the presence and in the absence of peppermint oil (Mentha piperita). Our results showed that pepper...

Controlled release (CR) Ciprofloxacin (CFX) matrix tablets were prepared using Ciprofloxacin betaine as a model drug and Kollidon SR as a core matrix former. Kollidon SR embedded CFX matrix tablets were then characterized with Carbopol 974P NF, Cetyl alcohol, Hydroxypropyl methyl cellulose (HPMC 4.5 cps). CFX release was 74% after 10 hours dissolution in 0.01 N HCl solution from the tablets con...

Floating matrix tablets of domperidone were developed to prolong gastric residence time and thereby increased drug bioavailability. Domperidone was chosen as a model drug because it is poorly absorbed from the lower gastrointestinal tract. The tablets were prepared by wet granulation technique, using polymers such as hydroxypropylmethylcellulose K4M, carbopol 934P, and sodium alginate, either a...

Ketoprofen is a potent non-steroidal anti-inflammatory drug which is used for the treatment of rheumatoid arthritis. The oral administration of ketoprofen can cause gastric irritation and renal adverse effects. Topical application of the drug can bypass gastrointestinal disturbances and provide relatively consistent drug levels at the site of action. Since the efficacy of gels depends on the ty...

Semi-synthetic hydrogels made of carboxymethyl hyaluronic acid (CMHA) and polyacrylic (PAA) were synthesized using electron beam irradiation. CMHA, with a degree substitution 0.87 molecular weight 149 kDa, was mixed linear PAA slightly crosslinked (Carbopol). The equal ratio the CMHA-Carbopol blends (10% 10% Carbopol) successfully crosslinked, even at low irradiation dose 20 kGy, producing hydr...

Polydimethylsiloxane (PDMS) elastomer is used in a wide range of biomaterial applications including microfluidics, cell culture substrates, flexible electronics, and medical devices. However, it has proved challenging to 3D print PDMS in complex structures due to its low elastic modulus and need for support during the printing process. Here we demonstrate the 3D printing of hydrophobic PDMS pre...
