20110201624 | Pharmaceutical Composition for Prevention and Treatment of Diabetes or Obesity Comprising a Compound that Inhibits Activity of Dipeptidyl Peptidase-IV, and other Antidiabetic or Antiobesity Agents as Active Ingredients - The present invention relates to a pharmaceutical composition for the prevention and treatment of diabetes or obesity comprising as active ingredients a compound which inhibits the activity of dipeptidyl peptidase-IV (DPP-IV), a pharmaceutically acceptable salt thereof, a hydrate thereof, or a solvate thereof, and one or more other antidiabetic or antiobesity agents. The pharmaceutical composition exhibits excellent glucose tolerance and may be useful in the prevention and treatment of diabetes, obesity, and the like by effectively inhibiting blood glucose levels and reducing fat mass. | 08-18-2011 |
20100240725 | NOVEL 1,3-DIHYDRO-5-ISOBENZOFURANCARBONITRILE DERIVATIVES AND PHARMACEUTICAL COMPOSITION THEREOF FOR THE TREATMENT OF PREMATURE EJACULATION - Disclosed herein are novel 1,3-dihydro-5-isobenzofurancarbonitrile derivatives represented by Formula 1, or pharmaceutically acceptable salts thereof. Also disclosed is a pharmaceutical composition for treating or preventing premature ejaculation including the compound. The 1,3-dihydro-5-isobenzofurancarbonitrile derivatives have a short half-life and inhibit the ejaculation process by selectively inhibiting serotonin reuptake via a serotonin reuptake transporter present in a presynaptic neuron. Thus, the compounds are useful in the treatment and prevention of premature ejaculation. | 09-23-2010 |
20100173915 | PHARMACEUTICAL COMPOSITIONS FOR THE TREATMENT OF CHRONIC HEART FAILURE COMPRISING PYRAZOLOPYRIMIDINONE DERIVATIVE COMPOUND - Disclosed herein is a therapeutic agent for chronic heart failure comprising, as an effective ingredient, 5-[2-propyloxy-5-(1-methyl-2-pyrrolidinyl-ethylamidosulfonyl)phenyl]-1-methyl-propyl-1,6-dihydro-7H-pyrazolo(4,3-d)pyrimidine-7-one. The compound inhibits phosphodiesterase-5 (PDE-5), which catalyzes the intracellular degradation of cyclic guanosine monophosphatase (cGMP), thereby mitigating several signs of chronic heart failure, that is, thereby preventing left ventricular dilatation, decreasing ventricular wall thinning, lowering elevated cardiac and circulating levels of atrial natriuretic peptide (ANP), and inhibiting ventricular fibrosis. Also, the compound has advantages in that it reaches the maximal plasma level in a short time, has an in vivo half-life longer than conventional PDE-5 inhibitors, allowing decreased administration frequency, and has fewer side effects, thus ensuring safety. Thus, the compound is useful as a therapeutic agent for chronic heart failure. | 07-08-2010 |
20100129459 | BIODEGRADABLE MICROSPHERE COMPOSITION SUITABLE FOR THE CONTROLLED RELEASE OF GLUCOSE CONTROLLING PEPTIDE AND FORMULATION THEREOF - Disclosed are biodegradable microspheres, capable of releasing a glucose-regulating peptide in a controlled manner, comprising a biodegradable polymer carrier with the glucose-regulating peptide encapsulated therein, and methods for the preparation thereof. In addition to ensuring high encapsulation efficiency and high stability of the encapsulated drug, the microspheres shows neither an initial burst effect nor incomplete release and allows the zero-order release of drugs over a prolonged period of time, thus improving the therapeutic effect of the drug. | 05-27-2010 |
20090099357 | AGENT FOR THE PREVENTION AND TREATMENT OF PROSTATIC HYPERPLASIA COMPRISING PYRAZOLOPYRIMIDINONE COMPOUND - The present invention relates to an agent for preventing and treating benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS) associated with BPH and a relaxant for relaxing urethral smooth muscle or prostatic smooth muscle comprising a pyrazolopyrimidinone compound as an effective ingredient. The agent in accordance with the present invention can provide nitric oxides by inhibiting the activity of PDE-5 that decomposes c-GMP, and the provided nitric oxides relax the urethral smooth muscle or the prostatic smooth muscle to lower the intraurethral pressure (IUP), thus treating BPH and LUTS associated with BPH. Furthermore, the time required for reaching a maximum blood concentration is shorter and the half-life is longer than the other PDE-5 inhibitors, thus reducing the frequency of administration. Moreover, the agent of the invention causing few side effects can be efficiently used as a safe drug. | 04-16-2009 |
20080207646 | Agent For the Prevention and Treatment of Liver Diseases Containing Pyrazolopyrimidine Derivative - The present invention relates to the pharmaceutical composition for prevention and treatment of liver diseases containing pyrazolopyrimidine derivative as all active ingredient. According to the present invention, pyrazolopyrimidine derivative has an excellent effect on inhibiting collagen synthesis in hepatic stellate cells and acts directly on the portal vein. Particularly, it may increase the diameter and the amount of blood flow of the portal vein, and finally decrease the pressure thereof. Therefore, pyrazolopyrimidine derivative can be used advantageously for prevention and treatment of hepatic fibrosis, liver cirrhosis caused by hepatic fibrosis, portal hypertension and various complications caused by portal hypertension. In addition, pyrazolopyrimidine derivative according to the present invention can reduce dosing frequency because of its long half-life, and therefore, has an advantage to improve the drug compliance of patients suffering from chronical liver diseases. | 08-28-2008 |
