PHARMACEUTICAL COMPOSITIONS OF DRONEDARONE AND ESSENTIAL FATTY
ACIDS Field of Invention
The present invention relates to a pharmaceutical composition comprising dronedarone or a pharmaceutically acceptable salt in combination with essential fatty acids or their esters or mixtures thereof and at least one pharmaceutically acceptable excipient.
The background of the invention
Dronedarone is a noniodinated benzofuran derivative with antiarrhythmic properties. It is an amiodarone analog that differs structurally from amiodarone in that the iodine moiety was removed and a methane sulfonyl group was added. These modifications reduce thyroid and other adverse effects and makes dronedarone less lipophilic, with a shorter half-life. The chemical name of dronedarone is N-[2-butyl-3-[4-[3-(dibutylamino)propoxy]benzoyl]-1 - benzofuran-5-yl]methanesulfonamide and it has the structure shown in the following formula I.
Figure imgf000002_0001
Formula I : Dronedarone Formula II: Dronedarone hydrochloride Dronedarone hydrochloride (shown in formula II) is an antiarrhythmic drug indicated to reduce the risk of hospitalization for atrial fibrillation (AF) in patients in sinus rhythm with a history of paroxysmal or persistent AF. It was approved by the FDA on 2009 and marketed under the brandname MULTAQ™. Recommended dose is one tablet of 400 mg twice a day with morning and evening meals. Following oral administration in fed conditions, dronedarone is well absorbed (at least 70 %) from intestines to blood. Because of presystemic first pass metabolism the absolute bioavailability of dronedarone without food is low, about 4%. It increases to approximately 15% when dronedarone is administered with a high fat meal.
In prior art, dronedarone and pharmaceutically acceptable salts thereof are described in EP 0 471 609 B1 . US 7 323 493 B1 discloses tablet formulations of dronedarone HCI. There are also several patent applications which dronedarone composition formulations, but none of them includes essential fatty acids.
Essential fatty acids (EFAs) are carboxylic acids that humans cannot synthesize but requires for the health. The term "essential fatty acid" refers to fatty acids required for biological processes. Because they cannot be synthesized within the human body, they must be obtained from the diet. There are two families of essential fatty acids: omega-3 (n-3) and omega-6 (n-6) fatty acids. As these fatty acids are not saturated with hydrogen (H) atoms (and contain more than one double bond between the atoms) they are also called ' polyunsaturated fatty acids ' (PUFAs).
The European Food Safety Authority, the American Heart Association, and other scientific and regulatory bodies confirm that essential fatty acids, especially omega 3 fatty acids are important for cardiovascular health. Omega 3 fatty acid consumption lowers plasma triglycerides, blood pressure, slows growth rate of atherosclerotic plaque and decreases risk of arrhythmias and also improves myocardial filling, efficiency and vascular function and also lower inflammation.
Especially, fish and fish oils contain essential fatty acids and in the treatment of cardiac arrhythmia especially in atrial fibrillation, fish or fish oil or essential fatty acid capsules are recommended in combination with antiarithmics. However, in prior art, there is no formulation which combines dronedarone and essential fatty acids in one dosage form. Instead of one per se use, combining more than one molecule in one dosage form increases the patients' quality of life and patients' compliance. Therefore, a composition of dronedarone and essential fatty acids in one suitable pharmaceutical dosage form is needed in the art.
On the other side, there are many challenges while combining two or more molecules in a dosage form such as dissolution, compatibility and stability problems. Each drug molecule has different dissolution and solubility properties. They may follow different absorption and distribution pathways after administration. For that reason, it is not easy to combine drug molecules in a same dosage form with desired dissolution profiles. They also may react with each other or with other used excipients and that may cause undesired instability problems. Moreover, due to solubility differences, many problems may be encountered during the process. Therefore, it is well known that even drugs used in the same therapeutic area or even for treating the same indication cannot always be combined into safe and efficacious dosage forms with the expectation of at least additive therapeutic effects.
Thus, a need occurs in the art which combines fatty acids and dronedarone in a same dosage form and overcome all problems above. In this present invention, dronedarone and essential fatty acids are combined in one dosage form and an effective and safe treatment of cardiovascular diseases is achieved.
Detailed description of the invention
The present invention relates to a pharmaceutical composition comprising dronedarone or a pharmaceutically acceptable salt thereof in combination with essential fatty acids or their esters or mixtures thereof and at least one pharmaceutically acceptable excipient.

According to one embodiment, dronedarone or a pharmaceutically acceptable salt used in this present invention is dronedarone hydrochloride (HCI).
According to this embodiment, dronedarone hydrochloride is present in an amount of between 3.0 to 95.0 %, preferably between 10.0 to 90.0 % and more preferably it is 15.0 to 70.0 % by weight of total formulation.
In this embodiment, dronedarone hydrochloride present in an amount of between 50 to 1200 mg, preferably 100 to 800 mg and more preferably it is 200 to 800 mg. In this present invention, dronedarone HCI is used as an antiarrithmic in combination with omega 3 fatty acids, for use in the treatment of cardiovascular diseases, especially for cardiac arrhythmia and to prevent serious or life-threatening side effects in patients.
In one embodiment, a pharmaceutical dosage form comprising dronedarone HCI in combination with omega 3 fatty acid has been developed providing a stable pharmaceutical combination with safe and effective dissolution profiles for each drug molecule.
In this embodiment, it has been found that in spesific ratio of dronedarone HCI to omega 3 fatty acid which is between 0.010 - 35.0(w/w), preferably 0.1 - 30.0 (w/w) and more preferably 0.1 - 25.0 (w/w) helps the formulation easily processed into a dosage form, in desired weight which can easily be swallowed by the patients.
According to this embodiment, in this present invention, pharmaceutical composition formulated in one dosage form provides desired dissolution profile for both dronedarone HCI and omega 3 fatty acid.
