This study was conducted to elucidate the mechanism underlying the hypolipidemic action of karaya saponin or Rhodobacter (R.) capsulatus. A total of 40 laying hens (20-week-old) were assigned into four dietary treatment groups and fed a basal diet (as a control) or basal diets supplemented with either karaya saponin, R. capsulatus, or both for 60 days. The level of serum low-density-lipoprotein...

Dietary karaya saponin and Rhodobacter capsulatus (R. capsulatus) are known to have hypocholesterolemic actions, as reported in our previous studies. This study examined possible synergistic hypocholesterolemic effects of karaya saponin and R. capsulatus in broilers. A total of 150 broilers were allocated into 10 treatments: control, saponin 25 mg, saponin 50 mg, saponin 75 mg, saponin 25 mg+R....

The aim of the current investigation is to study the kinetics of drug release pattern from buccal swellable, controlled release tablets of amoxicillin trihydrate. Buccal tablets were prepared with modified gum karaya in 5-20% concentration. Drug release from the formulated amoxicillin trihydrate loaded buccal tablets followed Zero order kinetics resulting in regulated and controlled release for...

BACKGROUND We investigated an outbreak involving 2 patients hospitalized at hospital A with cutaneous Rhizopus arrhizus (oryzae) infections of surgically created stomas. METHODS A cohort study involving all patients having ileostomy or colostomy surgery during the outbreak period (January-April 2005) was performed. Environmental samples, including samples obtained from nonsterile karaya (a pl...

The present study investigates the effect of crystalline and amorphous carriers for the improvement of dissolution profile of broad spectrum antifungal agent Itraconazole. A comparative study was performed to estimate the ability of Poloxamer-407 (crystalline carrier) and modified Gum Karaya (amorphous carries) for enhancing the dissolution profile of Itraconazole (BCS class II). Solid dispersi...

Purpose: To develop sustained release matrix tablets of diltiazem hydrochloride (DTZ) using modified karaya gum (MK). Methods: MK was prepared by cross-linking karaya gum with tri-sodium tri-metaphosphate (STMP) which was used as a cross-linker. Matrix tablets of DTZ were prepared using varying ratios of unmodified karaya gum (K) and MK by direct compression. The matrix tablets were evaluated f...

The present study outlines a systematic approach for designing and development of Ofloxacin floating tablets to enhance the bioavailability and therapeutic efficacy of the drug. Floating tablets of Ofloxacin have shown controlled release thereby proper duration of action at a particular site and are designed to prolong the gastric residence time after oral administration. Floating tablets of Of...

Purpose: Albendazole is a poorly soluble drug which limits its oral bioavailability. The study was focussed to enhance the solubility by in-situ micronization. Methods: Albendazole microcrystals were prepared by solvent change method using gum karaya and hupu gum as stabilizing agents and the effect of each stabilizer on the prepared microcrystals were studied. FT-IR, DSC, XRD and SEM analysis ...

Purpose: To develop orally disintegrating tablets of ondansetron HCl using natural Superdisintegrants. Method: Tablets containing the drug were prepared by dry granulation method using different concentrations of superdisintegrants such as modified gum karaya, modified natural agar, crosscarmellose sodium and sodium starch glycollate. The formulations were evaluated for weight variation, hardne...

Purpose: To develop sustained release matrix tablets of diltiazem hydrochloride (DTZ) using karaya gum (K) alone or in combination with locust bean gum (LB) and hydroxypropyl methylcellulose (H). Methods: Matrix tablets of DTZ were prepared at different ratios of drug:gum (1:1, 1:2, and 1:4) and of the gum blends (K, K/LB, K/H and K/LB/H) by direct compression. The matrix tablets were evaluated...
