  • Patent number: 8242159
    Abstract: 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.

  • Publication number: 20110250279
    Abstract: This invention relates to a controlled-release composition for producing a sustained-release preparation containing udenafil, including (A) udenafil and a pharmaceutically acceptable salt, (B) a solubility modulator, (C) an adsorbent, and (D) a hydrophilic polymer. This controlled-release composition for producing a sustained-release preparation containing udenafil releases drugs constantly regardless of the pH level in the gastrointestinal tract, and thus freely controls the drug release time within the range of 3˜24 hours, and reduces the variability in the effect of drugs among individuals. Also, this composition can be produced into a sustained-release preparation which has an optimum condition for expressing the effect of drugs in the treatment of diseases including pulmonary arterial hypertension, hepatic portal vein hypertension, benign prostatic hyperplasia, and the like, which can be treated by udenafil and which requires the long-term drug administration.

  • Publication number: 20100267818
    Abstract: This invention relates to a single-liquid pharmaceutical composition for injection containing docetaxel. The composition includes (A) docetaxel and pharmaceutically acceptable salts thereof, (B) a surfactant selected from the group consisting of polysorbate, polyoxyethylene glycol ester and polyoxyethylene castor oil derivatives, (C) a solvent comprising anhydrous ethanol in a concentration range of 100 to 800 mg/ml, in an injectable solution, and (D) a pH adjuster of an amount suitable for adjusting the pH of the liquid composition to 5 or less. The composition may be directly diluted in a perfusion liquid even without the use of an intermediary dilute solution in case the composition is used for injectable preparations since the composition is in a single liquid phase. Furthermore, the composition is suitable for effective administration of docetaxel since the pharmaceutical stability of the composition is significantly improved.

  • Publication number: 20100173915
    Abstract: 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.
