Description
"PROCESS FOR THE PREPARATION OF A GRANULAR ORAL COMPOSITION"
TECHNICAL FIELD
The present invention relates to a process for the preparation of a granular oral composition having a low dissolution time.
BACKGROUND
Iodine has long been used in various pharmaceutical forms (solution, tincture) for disinfection of small wounds. Despite this efficacy, it has number of side effects.
Povidone-iodine (Merck Index 13th edition, 2001) is a complex of polyvinylpyrrolidone as a polymer of l-vinyl-2-pyrrolidone and iodine, and has been widely used all over the world as a safe medicament having a bactericidal action for an agent for treating bedsore, sterilization of fingers and hands, disinfection of oral cavity, pharynx and the like. A gargle which is diluted with water before use has been generally used as a povidone-iodine agent for disinfection of the oral cavity and pharynx.
Owing to its complexation with Polyvinylpyrrolidone, iodine is released slowly and gradually thus reducing its side effects. It has long been used in the prophylactic and therapeutic field during the management of various infections. Free iodine, slowly liberated from the povidone-iodine (PVPI) complex in solution, kills eukaryotic or prokaryotic cells through iodination of lipids and oxidation of cytoplasm and membrane compounds. This compound is a broad spectrum antiseptic and exhibits a broad range of microbicidal activity against bacteria, fungi, protozoa, and viruses.
US 5846564 discloses an effervescent composition for the extemporaneous preparation of iodinated polyvinylpyrrolidone solutions, employs at-least one disintegrant, apart from
iodinated polyvinylpyrrolidone and at- least one effervescent agent. It claims to have dissolution time of around 3 to 10 minutes.
Thus there is a rising need for the development of an iodinated polyvinylpyrrolidone composition having a low dissolution time. The inventors of the present invention have tried to overcome this problem by providing a process for the preparation of a granular oral composition having a low dissolution time.
SUMMARY
The present invention relates to a process for the preparation of a granular oral composition comprising polyvinylpyrrolidone-iodine complex in granular form and involves the following steps: i. mixing 5 to 10% polyvinylpyrrolidone iodine powder, a soluble diluent with 20 to 25% effervescent agent and 17 to 25% acidifying agent having moisture content less then 0.2% w/w and particle size less then 250 micron; ii. granulating the above mixture with 80% isopropyl alcohol;
iii. granulating with 1 : 1 hydro alcoholic solution;
iv. drying the granules obtained at a temperature not exceeding 40°C; and v. Micronizing the granules to size less than 175 micron.
The invention will now be discussed with reference to the accompanying examples. DESCRIPTION
The present disclosure provides a process for the preparation of a granular oral composition comprising polyvinylpyrrolidone-iodine complex in granular form.
The process comprises the following steps: i. mixing 5 to 10%> polyvinylpyrrolidone iodine powder, a soluble diluent with 20 to 25% effervescent agent and 17 to 25% acidifying agent having moisture content less then 0.2% w/w and particle size less then 250 micron;
ii. granulating the above mixture with 80% isopropyl alcohol; iii. granulating with 1 : 1 hydro alcoholic solution;
iv. drying the granules obtained at a temperature not exceeding 40°C; and v. Micronizing the granules to size less than 175 micron.
The entire manufacturing process is to be carried out at relative humidity less then 30% and a temperature below 25 °C. The controlled granulation process employed, results in characteristic granules which have faster solubilization. Further, the composition prepared by the process of the present invention has a dissolution time of less than 3 minutes and does not employ any disintegrant. This results in a faster and complete solubilization of Polyvinylpyrrolidone-Iodine (PVP-I), when the granules are dissolved in water. In one of the embodiments the effervescent agent is selected from sodium and potassium carbonate, sodium and potassium bicarbonate, sodium glycine carbonate and calcium carbonate.
In another embodiment the acidifying agent is selected from anhydrous citric acid, carbonic acids, monohydrated or anhydrous malic acid, fumaric acid or tartaric acid.
The sweetener is selected from sodium saccharine, sucralose, aspartame, acesulfame - K and tagatose The composition of the present invention, is useful in oral care, providing extemporaneous production of Iodinated - Polyvinylpyrrolidone (PVP-I) in solution form. It is very handy, economical and reproducible drug delivery system, having less storage and handling space requirement. EXAMPLE
