Evaluation of Sugar Content and Erosive Potential of the Commonly Prescribed Liquid Oral Medications

Abstract Objective: To assess the total sugar content, endogenous pH, total soluble solids content (TSSC) and titratable acidity of the commonly prescribed long-term and short-term liquid oral medicines (LOM) for children and to compare the erosive potential with the total sugar content and total soluble solids of the LOM. Material and Methods: Twenty-three most commonly prescribed pediatric LOM were evaluated in-vitro for the cariogenic and erosive potential. Manufacturers' information on labels, endogenous pH, titratable acidity, TSSC, and the total sugar content was determined. Descriptive statistics and the Mann-Whitney U test were applied. Results: Overall, 22 LOM contained sugar. Only 3 LOM revealed the sugar content of the formulation but did not disclose the quantity (Cheston, Ventorlin and Eptoin). None of the samples revealed the sugar content as well as endogenous pH in their labels. The overall mean total sugar content was 6.92 ± 3.49 g/100ml, ranging from 3.40 ± 0.00 (corticosteroids) to 9.67 ± 0.61 (antitussive/expectorant). The mean endogenous pH for the total sample of medicines was 5.91 ± 1.51 (range of 3.5 to 10.3). Eptoin (0.013%) presented the lowest titratable acidity and Imol (1.171%) presented the highest titratable acidity with an overall mean of 0.40 ± 0.73. Omnacortil and Epilex presented the highest TSS content (19.3%), and Ventorlin presented the lowest TSS content (18.7%) with an overall mean of 18.97 ± 0.19. Over twelve medicines were identified to have the potential to cause dental erosion. No significant differences were seen in the total sugar content, total soluble solids, titratable acidity, and the endogenous pH between the short-term and long-term LOMs (p=0.145, p=0.263, p=0.067 and p=0.107), respectively. Conclusion: The pediatric LOMs showed the presence of the sugar, low endogenous pH, high titratable acidity and high total soluble solids.

A comparitive study on iodination of normal and diabetic serum.

It is a well known fact that iodine is a very important trace element for normal growth and metabolism. Iodination of biomolecules has many important functions in the field of research, assay procedures, investigation and diagnosis of diseases. The present study is done to compare the iodine uptake by the serum of diabetes mellitus cases and healthy controls. Methods: The study was carried out on 50 cases of known diabetes mellitus with mean fasting blood glucose level of 324 mg/dl and 25 healthy controls with mean fasting blood glucose level of 78 mg/dl. The modified version of the colorimetric method was employed for the assay of iodine uptake. The data’s were analyzed using SPSS version 10. Results: Serum total iodine uptake was decreased significantly in cases as compared to healthy controls (p <0.01). Conclusion: The results of our study indicate that there is decreased iodine uptake by diabetic serum. The cause for decreased iodine uptake may be related to high blood sugar level which possibly may be causing some alteration in the structure of biomolecules by glycation leading to decrease in the binding sites of iodine.
