Description

RAPIDLY DISPERSING PHARMACEUTICAL FORMULATION WITH
CEFDINIR
Present invention relates to water dispersible pharmaceutical dosage forms comprising cefdinir as active agent and methods for preparation thereof
Background of the invention
Cefdinir molecule which is shown with Formula I was first disclosed in the patent numbered BE897864 and its chemical name is (6R,7R)-7-[[(2Z)-(2-amino-4- thiazolil)(hydroxyimino)acetyl] amino]-3-ethenyl-8-oxo-5-thia-l-azabicyclo[4.2.0]oct-2-en-2- carboxylic acid. The molecule which is a third generation cephalosporin, is indicated for the treatment of several illnesses caused by gram positive and gram negative bacteria.
ormii
Cefdinir which physically appears as a white powder has very poor solubility in common organic solvents such as methanol, ethanol, and acetonitrile and in water. Due to this property there are some problems while developing formulations comprising this molecule and in the bioavailability of the finished product.
Cefdinir do not dissolve in water and also its wettability is very low, this causes problems while developing water dispersible formulations and also for this reason sefdinir has low bioavailability.
The product sold in the market under the trade name OMNICEF® is present in capsule and suspension forms. Clinic studies show that the bioavailability of the suspension product is 120% more than the bioavailability of the product in capsule form.
Although the suspension forms have higher bioavailability, use of this dosage form especially for pediatric and geriatric patients brings about .the possibility of taking high and/or uncontrolled dose. Additionally, the fact that the suspensions have physical and chemical stability problems, they have short shelf life and high production costs and the fact that they cause problems while transporting and use are disadvantageous for the manufacturers.
Due to the reasons stated above it is necessary to provide new dosage forms in antibiotic theraphy in order to provide effective dosing, meet patient requirements and to offer different alternatives to patients having special conditions, such as pediatric and geriatric patients. Subject of the present invention is related to cefdinir formulations that disperse in water in less than 10 minutes and that do not comprise dispersing agent or effervescent agent. This way it was aimed to develope cefdinir formulations which disperse in water and provide ease of use for the patients without using dispersing agent and acidic and basic effervescent couple which increases the cost of manufacture. Accordingly present invention relates to cefdinir formulations wherein at least 90% of the formulation dissolve in water in less than 10 minutes.
Said formulations dissolve in water without requiring any physical intervention such as stirring, shaking etc. and without effervescence.
Formulations according to present invention are preferably in sachet form. Cefdinir formulations according to present invention have
• Higher bioavailability since they are used by dissolving in water
• Higher stability since they are packed in solid form in single dose units
• Dose accuracy since they are packed in single dose units,
• Lower cost since they do not comprise effervescent couple and dispersing agent For these reasons, cefdinir formulations according to present invention provide formulating cefdinir, which is a compound that hardly disperse in water and dissolving of at least 90% of said formulation in water in less than 10 minutes.
In another aspect present invention relates to cefdinir formulations wherein at least 90% of said formulation dissolve in water in less than 10 minutes. Accordingly said formulations may comprise pharmaceutically acceptable excipients in addition to cefdinir that is used as active agent.
