Abstract

This invention is concerned with the use of date syrup used as a binder (agglutinant) for solid dosage forms, such as tablets. The features of the granules and the tablets have been studied in comparison with granules and tablets which use different types of agglutinants such as starch paste and sucrose syrup and the results have shown that the use of date syrup as a binder for tablets yields results superior to other kinds of binders. In addition, date syrups gives the granules and tablets a fair color, good taste, distinct and pleasant odor, and it is favorable in regards to shape and taste by patients.

Claims (18)

1. A method for producing a composition wherein the method comprises the use of an agglutinant for granulation of water-soluble substances and water-insoluble substances, wherein the agglutinant consists essentially of a date syrup having only soluble date components.

2. The method according to claim 1 , used to manufacture a solid dosage form.

3. The method according to claim 1 , wherein said date syrup is used at a concentration in the range of from 40% to 60% (w/w date syrup:water).

4. The method according to claim 1 , wherein the agglutinant is an agglutinant for a solid dosage form selected from tablets, pills, lozenges, capsules, suppositories, powders, and granules.

5. The method according to claim 1 , wherein said date syrup is used as agglutinant in an agglutinant solution, and-wherein the specific gravity is 0.8-1.3 g/ml, and/or the viscosity is 4-20 cP, and/or the pH value is in a range of from 3-5.

6. The method according to claim 1 , wherein said water-soluble substances and said water-insoluble substances are assessed by their average molecular size, apparent density, pitting density and rest angle.

7. The method according to claim 4 , wherein said water-soluble substances and water-insoluble substances are granulized separately using date syrup as tablet agglutinants to prepare solid dosage form granules and tablets.

8. The method according to claim 7 , wherein the shape and structure of the granules and tablets of said water-soluble and water-insoluble substances prepared are studied using an electron microscope in order to differentiate and obtain granules and tablets based on their average molecular size, strength of molecule, apparent density, pitting density and rest angle.

9. The method according to claim 1 , wherein tablets are manufactured from the granules prepared, using a tablet machine.

10. The method according to claim 9 , wherein the manufactured tablets are assessed and studied according to the American Pharmaceutical Constitution, Article 22, in relation to weight symmetry, time of disintegration, fragility test, and hardness test.

11. The method according to claim 1 , wherein the taste and flavor of the tablets manufactured is tested on a sample of volunteers.

12. A solid dosage form, comprising an agglutinant, wherein the agglutinant consists essentially of date syrup having only soluble date components.

13. The dosage form according to claim 12 , selected from the group comprising tablets, pills, lozenges, capsules, suppositories, powders and granules.

14. The dosage form comprising date syrup as an agglutinant, wherein said dosage form has been prepared using the method in accordance with claim 1 .

15. The method, according to claim 1 , wherein the water-soluble substance is sodium bicarbonate.

16. The method, according to claim 1 , wherein the water-insoluble substance is calcium carbonate.

17. The method, according to claim 5 , wherein the pH is 4.5.

18. The method, according to claim 1 , further comprising the step of adding at least one additional ingredient selected from the group consisting of: lubricants, agents influencing release profile, binder substances and humectants.
