The colon is a promising site for drug targeting owing to its long transit time and mild proteolytic activity. The aim of this study was to prepare new low methoxy amidated pectin/NaCMC microspheres cross-linked by a mixture of Zn(2+) and Al(3+) ions and test their potential for colonic targeting of progesterone. A 2(4) factorial design was carried out to optimize the preparation conditions. Hi...

Postpartum hemorrhage is an obstetrical emergency that represents the leading cause of maternal mortality. Severe hemorrhagic complications that could appear postpartum are the abdomino-pelvic hematomas, which result from the rupture of the pelvic vessels. We reported a very rare case of puerperal retroperitoneal subserosal hematoma of sigmoid colon following vaginal delivery, which was success...

The purpose of this research was to develop and evaluate multiparticulates of alginate and chitosan hydrogel beads exploiting pH sensitive property for colon-targeted delivery of theophylline. Alginate and chitosan beads were prepared by ionotropic gelation method followed by enteric coating with Eudragit S100. All formulations were evaluated for particle size, encapsulation efficiency, swellab...

The design, synthesis and delivery potential of a new type of benzenesulfonamide cyclo-oxygenase-2 (COX-2) inhibitor prodrug is investigated using celecoxib. The approach involves a double prodrug that is activated first by azoreductases and then by cyclization triggering drug release. We studied the intramolecular aminolysis of the acylsulfonamide. The cyclization was surprisingly rapid at phy...

Nanosponge and Microsponge delivery System was originally developed for topical delivery of drugs can also be used for controlled oral delivery of drugs using water soluble and bioerodible polymers. It holds a promising future in various pharmaceutical applications in the coming years like enhanced product performance and elegancy, extended release, reduced irritation, improved thermal, physica...

A 3-day-old term male child weighing 2.1 Kg, born by spontaneous vaginal delivery, was admitted with complaints of abdominal distention, meconuria and absent anal opening. This was the first child of the couple who had a non-consanguineous marriage. On examination, there was abdominal distention, poorly developed gluteal folds and an absent anal opening. Plain X-ray abdomen showed two large air...

Ulcerative colitis (UC) is a chronic, immunologically-mediated disorder which affects the gastrointestinal tract. This disease is characterized by inflammation of the colonic or rectal mucosa, leading to rectal bleeding, diarrhea, and abdominal pain. UC, along with Crohn’s disease, is referred to as inflammatory bowel disease. The specific cause of this disease is unknown, but research has sugg...

Mesalamine is a gold standard anti-inflammatory drug used to treat inflammatory bowel illnesses. It's usually and keep Ulcerative Colitis in remission mild moderate cases. rapidly cleared from circulation after being consumed orally, with an elimination half-life of only one hour. Oral intake delayed or slow released matrix formulations can acquire therapeutic concentration the intestines. The ...
