- Degradation of raw or film-incorporated beta-cyclodextrin by enzymes and colonic bacteria.
- Fetzner A, Böhm S, Schreder S, Schubert R.Author information Merck KGaA, Department of Pharmaceutical Development, Darmstadt, Germany.Abstractbeta-cyclodextrin (beta-CD) is a suitable excipient for peroral use, which improves the solubility of lipophilic drugs, as well as for colon-specific drug release when it is mixed with coating polymers. The first aim of this work was to examine the suitability of various enzymes as a simple in vitro model for the glycolytic activity in the human colon. alpha-Amylase (source Aspergillus oryzae) and taka diastase (source A. oryzae) showed remarkable degradation capacity of free beta-CD, whereas other alpha-amylases (sources Bacillus subtilis or Hog pancreas) were found to be unsuitable. The next aim was to find out if film-incorporated beta-CD is also degraded by these enzymes. Therefore, diffusion studies of 5-aminosalicylic acid (5-ASA) through Eudragit RS or Eudragit NE films containing beta-CD were performed with taka diastase present in the buffer medium. Pronounced diffusion of the drug through the Eudragit RS film was found only when swelling excipients like crosslinked sodium carboxymethylcellulose (CMC-CL sodium) or polyvinylpyrrolidone (PVP 25) were present in the film, indicating enhanced accessibility of beta-CD by the enzyme. Films containing CMC-CL without beta-CD showed even higher permeability, which also points to enzymatic degradation of CMC-CL. Permeabilization by taka diastase of Eudragit NE films without swelling agents correlated with the beta-CD content, whereas control films containing talcum remained impermeable upon enzyme action. Furthermore, the beta-CD degradation capacity of colonic bacteria like Escherichia fergusonii, Serratia odorifera or Proteus mirabilis was examined with beta-CD coatings on tablets, which contained bisoprolol as a model drug. Tablets with beta-CD-containing Eudragit RS coatings showed the highest drug release upon incubation with P. mirabilis. The moderate drug release by E. fergusonii could be increased almost to the same level when the bacteria were pre-incubated for 24 h in medium containing 2.5 mg/ml beta-CD, indicating the induction of glycolytic enzymes by beta-CD in this colonic bacteria strain.

- Reversed-phase liquid chromatography on an amide stationary phase for the determination of the B group vitamins in baby foods.
- Viñas P, López-Erroz C, Balsalobre N, Hernández-Córdoba M.Author information Department of Analytical Chemistry, Faculty of Chemistry, University of Murcia, E-30071 Murcia, Spain.AbstractA liquid chromatographic method for the separation and determination of several water-soluble vitamins of the B group is proposed. The procedure is based on the use of a new amide-based stationary phase, which avoids the need of using the ion-pair technique, leading to narrower peaks and a simpler mobile phase. Analyses were performed by gradient elution with acetonitrile-phosphate buffer as mobile phase and using a photodiode array detector. Specificity was demonstrated by the retention characteristics, UV spectra and by comparing the peak purity index with commercial standards. Linearity, precision, recovery and sensitivity were satisfactory. The vitamins are extracted from the baby food using a single digestion with hydrochloric acid followed by enzymatic digestion with taka-diastase. The method was successfully applied to the determination of nine vitamins: thiamine, riboflavin, nicotinamide, nicotinic acid, pyridoxine, pyridoxal, folic acid, cyanocobalamine and inosine in different baby foods as infant formulas, cereals and fruit products. Validation was performed using two certified reference materials.

- Drug eruption (erythema multiforme type) due to a digestive enzyme drug.
- Miyoshi H, Kanzaki T.Author information Department of Dermatology, Kagoshima University Faculty of Medicine, Japan.AbstractAn 84-year-old Japanese male had pruritic indurated erythema on his upper limb and left lower abdomen, which had developed abruptly two months before visiting our hospital. Hematological examination showed eosinophilia, 550/mm3. Histopathological findings were suggestive of erythema multiforme in response to a drug. By means of patch tests and a p.o. challenge test, Aczym, a digestive enzyme drug, was shown to be the cause of his condition. Further study revealed that the specific ingredients involved were pancreatin and Taka-diastase. An eruption resulting from ingestion of a digestive enzyme drug has not previously been reported.
