Calcium butyrate: Anti-inflammatory effect on experimental colitis in rats and antitumor properties.

Butyric acid is a physiological component of the colonic environment that possesses anti-inflammatory and antitumor properties, among others. However, little is known regarding its effects following direct application on the colonic surface. This study was conducted to investigate the topical anti-inflammatory effect of calcium butyrate in chemically-induced colitis in rats and to evaluate its antitumor properties and .

Anti-inflammatory and immunomodulatory activities of rifamycin SV.

There have been several reports showing convincing evidence for non-bactericidal activities of the rifamycin antibiotics. In particular, the parent compound rifamycin SV has been employed in a limited number of cases to treat rheumatoid arthritis. Moreover, rifamycin SV and its derivative rifaximin have been found to be effective in experimental animal models of gut inflammation.

Cortexolone 17α-propionate 1% cream, a new potent antiandrogen for topical treatment of acne vulgaris. A pilot randomized, double-blind comparative study vs. placebo and tretinoin 0·05% cream.

Background: Acne vulgaris is a disorder of the pilosebaceous unit in which the androgens contribute to its onset and persistence. The use of antiandrogens is therefore potentially effective; however, antiandrogens for topical use are not available on the market. Cortexolone 17α-propionate (CB-03-01; Cosmo S.

In vitro activity and single-step mutational analysis of rifamycin SV tested against enteropathogens associated with traveler's diarrhea and Clostridium difficile.

Rifamycin SV is a broad-spectrum, poorly absorbed antimicrobial agent that, when coupled with MMX technology, is being targeted for the oral treatment of traveler's diarrhea (TD) and Clostridium difficile-associated disease (CDAD). Rifamycin SV was tested for activity against 911 TD-associated enteropathogens and 30 C. difficile isolates collected from several global surveillance studies.

Clinical trial: oral colon-release parnaparin sodium tablets (CB-01-05 MMX) for active left-sided ulcerative colitis.

Background: The administration of parnaparin sodium as oral colon-release tablets (CB-01-05 MMX) has been proposed as a novel approach for the treatment of ulcerative colitis (UC).

Aim: To assess the efficacy and the tolerability of 8 weeks' oral daily administration of 210 mg of parnaparin sodium compared with placebo in subjects treated with stable-doses of oral aminosalicylates.

Methods: This multicenter, randomized, double-blind proof of concept trial compared the efficacy of CB-01-05 MMX 210 mg tablets to placebo in 141 subjects with mild to moderately active left-sided UC treated with stable-doses of aminosalicylates.
