Co-transfection of hepatocyte growth factor and truncated TGF-β type II receptor inhibit scar formation

Braz. j. med. biol. res; 53 (1), 2020
Wound scarring remains a major challenge for plastic surgeons. Transforming growth factor (TGF)-β plays a key role in the process of scar formation. Previous studies have demonstrated that truncated TGF-β type II receptor (t-TGF-βRII) is unable to continue signal transduction but is still ...

Solid dispersion-based pellet for colon delivery of tacrolimus through time- and pH-dependent layer coating: preparation, in vitro and in vivo studies

The intent of the present investigation is to develop and evaluate colon-specific coated tacrolimus solid dispersion pellet (SDP) that retards drug release in the stomach and small intestine but progressively releases in the colon. Tacrolimus-SDP was prepared by extrusion-spheronization technology and op...

Use of solid dispersions to increase stability of dithranol in topical formulations

Braz. j. pharm. sci; 50 (3), 2014
The present study was planned to improve the stability of dithranol using solid dispersions (SD). Two different SD at a 1:9 ratio of dithranol/excipient were prepared: one of them using glyceryl behenate as excipient and the other using a mixture of argan oil with stearic acid (1:8 ratio) as excipient. P...

Development of fast dispersing tablets of nebivolol: experimental and computational approaches to study formulation characteristics

Braz. j. pharm. sci; 50 (4), 2014
Formulation of FDT (fast dispersing tablets) of nebivolol was optimized and evaluated using simplex lattice design (SLD). The influence of type and concentration of three disintegrants viz., Ac-Di-Sol, Primojel and Polyplasdone XL on hardness, friability and disintegration time of tablet was studied. Res...

Development and evaluation of ofloxacin orally disintegrating tablets

Braz. j. pharm. sci; 48 (2), 2012
Bitter taste of ofloxacin, a broad spectrum bactericidal agent, is masked and orally disintegrating tablets were formulated. The bitter taste is masked by forming complex between drug and weak cation exchange resins, Tulsion 335 and Indion 204. Effect of pH and drug:resin ratio on the drug loading was st...

Comparative study of sustained-release lipid microparticles and solid dispersions containing ibuprofen

Braz. j. pharm. sci; 48 (3), 2012
Ibuprofen is one of the most important non-steroidal anti-inflammatory drugs used in the treatment of inflammatory diseases. In its pure state, ibuprofen presents poor physical and mechanical characteristics and its use in solid dosage forms needs the addition of excipients that improve these properties....
