  • Publication number: 20190110994
    Abstract: Present invention discloses the stable pharmaceutical composition comprising premix of dapagliflozin with at least one pharmaceutically acceptable excipient(s) and process for preparation thereof. Dapagliflozin is highly hygroscopic and hence it is difficult to formulate dapagliflozin as stable pharmaceutical composition. Present invention discloses the stable pharmaceutical composition of dapagliflozin comprising premix of dapagliflozin with lactose.

  • Patent number: 10130624
    Abstract: A stable pharmaceutical composition consisting of (a) benazepril, in free or pharmaceutically acceptable salt form; and (b) amlodipine, in free or pharmaceutically acceptable salt form. The composition is free of alkali and alkaline earth metal carbonates and phosphates. The composition is also free of excipients which increase the pH of microenvironment above 5. It is therefore not required to physically separate the two drugs from each other.

  • Publication number: 20170258749
    Abstract: The present invention relates to pharmaceutical composition comprising two different populations with first population comprising oseltamivir or a pharmaceutical acceptable salt thereof and one or more pharmaceutically acceptable excipients and second population comprising one or more pharmaceutically acceptable excipients. Preferably, the compositions wherein the second population does not contain oseltamivir or a pharmaceutically acceptable salt thereof. The invention also disclose new method of filing the composition into container. The inventors of the present invention surprisingly found that the composition are stable in real-time and long-term stability conditions. Further, the compositions are bioequivalent to marketed suspension formulation of Oseltamivir phosphate.

  • Publication number: 20130115246
    Abstract: The invention relates to reduced dose oral pharmaceutical composition of fenofibrate which exhibits substantial bioequivalence to Antara® Capsules under fasting condition and also capable of reducing the food effect on bioavailability of fenofibrate. Provided is a pharmaceutical composition comprising about 90 mg of fenofibrate particles having a D90 particle size of less than about 600 nm and a pharmaceutically acceptable carrier, wherein the pharmaceutical composition is a solid dosage form suitable for oral administration and is substantially free of food effect such that when administered orally to a human provides an AUC0-t value for fenofibric acid in the blood plasma of the human under a fed state which is higher than the AUC0-t value under a fasted state by up to 12%, wherein t is 96 hours from the administration of the pharmaceutical composition.

  • Publication number: 20130039957
    Abstract: The present invention relates to controlled release pharmaceutical compositions comprising Brivaracetam or its pharmaceutically acceptable derivatives thereof. Further disclosed is a controlled release pharmaceutical composition comprising a core and a coating surrounding the core, wherein the core comprises Brivaracetam or pharmaceutically acceptable derivative thereof and the coating comprises hydrophobic release controlling agent. The controlled release pharmaceutical composition comprises Brivaracetam or pharmaceutically acceptable derivatives thereof and hydrophobic release controlling agent, wherein said composition has dissolution of Brivaracetam at least 80% between about 7 to about 24 hours when measured in 900 ml of pH 6 phosphate buffer solution using USP apparatus type II, at 50 rpm and at 37° C.
