Fast acting orally disintegrating film
First Claim
1. A fast acting orally disintegrating film, comprising:
- ondansetron or a pharmaceutical acceptable salt thereof in an amount of about 2 to about 24 mg;
a first hydrophilic film forming polymer comprising hydroxylpropylmethylcellulose (HPMC) in a total amount of from about 15% to about 50% by weight of said film, wherein said first hydrophilic film forming polymer is characterized by having a molecular weight of about 5000Da to about 50000Da and viscosity of about 3 cps or about 6 cps;
a second hydrophilic film forming polymer comprising HPMC characterized by having a molecular weight between about 50000Da to about 60000Da and viscosity of about 15 cps, and said first hydrophilic film forming polymer is mixed with said second hydrophilic film forming polymer in a ratio from about 0.3;
1 to about 7;
1; and
a water soluble excipient comprising polyethylene glycol (PEG) in an amount of about 10% to about 30% by weight of said film;
wherein the fast acting orally disintegrating film disintegrates within about 30 seconds in about 20 cc of water at about 37 degrees Celsius and lightly shaken.

Abstract
A fast acting orally disintegrating film (ODF) for treatment of various medical conditions including emesis that has a simple formulation, easy to manufacture and has similar pharmacokinetic profile to currently commercially available orally administered drug products is provided. The ODF comprises an active pharmaceutical ingredient such as ondansetron or a pharmaceutical acceptable salt thereof in an amount of 2 to 24 mg, at least one hydrophilic film forming polymer in an amount of at least 8% by weight of the film, wherein the at least one hydrophilic film forming polymer is characterized by having a molecular weight of 5000 to 50000 Da, and a water soluble excipient in an amount of 10 to 30% by weight of the film. The present invention also provides a method for preparing the ODF that remains stable over a period of time under a normal pharmacologically storage condition and a method for treating or preventing various medical conditions such as nausea or vomiting or a treatment method mediated through antagonizing action of 5HT at 5-HT3 receptor by administering the ODF to a patient in need thereof.
