  • Publication number: 20220202795
    Abstract: The present disclosure relates to a pharmaceutical composition containing esomeprazole or a pharmaceutically acceptable salt thereof and with a dual release profile, and particularly to a pharmaceutical composition which exhibits a dual release profile of immediate release and sustained release so that long-term efficacy can be sustained. The pharmaceutical composition containing esomeprazole or a pharmaceutically acceptable salt thereof and with a dual release profile, according to the present disclosure, can secure bioavailability equivalent to that of existing esomeprazole immediate-release/enteric-release formulations, and can maintain long-term efficacy due to the dual release profile thereof even when administered once a day, thus preventing the occurrence of nocturnal acid breakthrough, and accordingly, can be effectively used as a therapeutic agent for nocturnal acid breakthrough.

  • Publication number: 20200368219
    Abstract: Provided are a pharmaceutical composition including a core in a form of a multi-unit spheroidal tablet (MUST) containing esomeprazole or a pharmaceutically acceptable salt thereof, wherein the pharmaceutical composition is dissolved by 50 percent (%) or more within 15 minutes of an in vitro dissolution test; and a method of preparing the pharmaceutical composition. According to this, in case that the pharmaceutical composition is developed as the multi-unit spheroidal tablet, the dissolution may be accelerated in a condition of a slow stirring rate than that of a conventional pellet formulation or single tablet. Also, proton pump inhibitors (PPI)-based drugs including esomeprazole may be dissociated by gastric acid having a low pH, consequently inducing a decrease in bioavailability of the drug, but the pharmaceutical composition according to this may be minimize this.

  • Patent number: 9833413
    Abstract: Disclosed is a pharmaceutical combination formulation comprising a first discrete part containing amlodipine and rosuvastatin and a second discrete part containing losartan, which exhibits improved dissolution rate and stability. The inventive combination formulation comprising amlodipine, losartan and rosuvastatin having different action mechanisms from one another can be effectively used to prevent or treat a cardiovascular disorder. Designed to minimize an interaction among active ingredients, the pharmaceutical combination formulation exhibits excellent storage stability and dissolution rates of amlodipine, losartan and rosuvastatin, and thus can be useful in pharmaceutical industries.
