Description

[0001] THE PHARMACEUTICAL COMBINATION COMPRISING DAPOXETINE, PHOSPHODIESTERASE TYPE-5 INHIBITOR AND PANAX GINSENG

[0002] Field of the Invention

[0003] The present invention relates to a pharmaceutical combination comprising dapoxetine, a PDE5 inhibitor and furthermore panax ginseng.

[0004] Background of the Invention

[0005] Selective serotonin reuptake inhibitors (SSRI) are used in the long-term prophylaxis of many types of depression, including the endogenous type, recurrent depression, and in the treatment of obsessive-compulsive disorders, panic attack, social phobias, and the bulimia nervosa disease. Dapoxetine was first disclosed in the European patent publication EP0288188B1 is a selective serotonin reuptake inhibitor. Dapoxetine is used for the treatment of depression and premature ejaculation. The IUPAC name of dapoxetine is (S)-N, N-Dimethyl-3-(naphthalen-1- yloxy)-1-phenylpropan-1-amine and has a chemical structure shown with Formula I.

[0006] Formula I: Dapoxetine

[0007] Following oral administration, dapoxetine is rapidly absorbed and rapidly enters the circulation by almost completely binding to plasma proteins. Therefore, it achieves the peak plasma concentration (Cmax) in 1 hour following oral administration. Orally-administered tablets of dapoxetine are commercially available under the name Priligy®, comprising 30 mg or 60 mg dapoxetine per tablet, as well as excipients including lactose monohydrate, microcrystalline cellulose, croscarmellose sodium, colloidal anhydrous silica, magnesium stearate, hypromellose, titanium dioxide (E171), triacetin, black iron oxide (E172) and yellow iron oxide (E172).

[0008] On the other hand, phosphodiesterase type 5 inhibitors (PDE5 inhibitor) are used in the treatment of erectile dysfunction (ED). PDE5 inhibitors block the phosphodiesterase enzyme in a selective and efficient manner, thus increasing the level of cyclic guanosine monophosphate in the corpus cavernosum smooth muscle cells. Most frequently used PDE5 inhibitors are avanafil, lodenafil, mirodenafil, sildenafil, tadalafil, vardenafil, udenafil, zaprinast, benzamidenafil, dasantafil.

[0009] Tadalafil is a PDE-5 inhibitor used in the treatment of ED and pulmonary arterial hypertension (PAH). It has a longer half life as compared to other PDE-5 inhibitors (mean, 17,5 hours). Orally-administered tablets of Tadalafil are commercially available under the name Cialis®, in the strength of 2.5 mg, 5 mg, 10 mg and 20 mg, as well as excipients including lactose monohydrate, microcrystalline cellulose, croscarmellose sodium, hydroxypropylcellulose, sodium lauryl sulfate, magnesium stearate, hypromellose, titanium dioxide (E171), triacetin, yellow iron oxide (E172), talc. The IIIPAC name of tadalafil is (6R-trans)-6-(1 ,3-benzodioxol- 5-yl)- 2,3,6,7,12,12a-hexahydro-2-methyl-pyrazino [1',2':1 ,6] pyrido[3,4-b] indole-1 , 4-dione, with the chemical structure illustrated below with Formula II. Tadalafil is a water-insoluble molecule. As a result, the problem of fluidity and content uniformity is seen.

[0010] Formula II: Tadalafil

[0011] Formulations comprising a combination of selective serotonin reuptake inhibitors with PDE5 inhibitors are known in the prior art. The patent publication W003000343, for example, discloses the use of a formulation comprising a combination of phosphodiesterase inhibitors and dapoxetine.

[0012] In the prior art, there are also several patents which disclose combination with dapoxetine and tadalafil mostly in oral pharmaceutical dosage forms. However, while this combination is increasing the patients’ quality of life, combining more than one molecule in one dosage form may also cause undesired side effects which is nausea, vomiting, emesis, syncope, muscle, back and headache, fatigue, diarrhea, dizziness and hypotension. Panax ginseng also known as Asian ginseng, Chinese ginseng, or Korean ginseng is a species of plant whose root is the original source of ginseng. It is a perennial plant that grows in the mountains of East Asia. It is among the most extended living plants. Studies show that Panax ginseng improves learning ability, has an antidepressant effect, improves neurological functions, reduces DNA, protein and lipid damage, balances blood pressure and increases blood circulation. It is also reported that it is effective on the protection and healing of the liver, has a positive effect on men with erectile dysfunction, can inhibit cell growth in various cancer cells, and reduces the viability of various cancer cells by preventing the vascularization of cancer.

[0013] Therefore, there is a need in the prior art for a new combination of dapoxetine and tadalafil that will provide the elimination of the mentioned side effects and problems of fluidity and content uniformity with panax ginseng extract. In this present invention, panax ginseng is used to overcome the disadvantages and side effects of the combinations of dapoxetine and tadalafil meanwhile increasing the therapeutic effect and patient compliance in the desired manner.
