Sustained Release Dosage Forms

Sustained release dosage forms are designed to release a drug at a predetermined rate in order to maintain a constant drug concentration for a specific period of time with minimum side effects. This can be achieved through a variety of formulations, including liposomes and drug-polymer conjugates (an example being hydrogels). Sustained release's definition is more akin to a "controlled release" rather than "sustained".

Famous quotes containing the words forms, sustained and/or release:

    A strange effect of marriage, such as the nineteenth century has made it! The boredom of married life inevitably destroys love, when love has preceded marriage. And yet, as a philosopher has observed, it speedily brings about, among people who are rich enough not to have to work, an intense boredom with all quiet forms of enjoyment. And it is only dried up hearts, among women, that it does not predispose to love.
    Stendhal [Marie Henri Beyle] (1783–1842)

    The usual derivation of the word Metaphysics is not to be sustained ... the science is supposed to take its name from its superiority to physics. The truth is, that Aristotle’s treatise on Morals is next in succession to his Book of Physics.
    Edgar Allan Poe (1809–1849)

    We read poetry because the poets, like ourselves, have been haunted by the inescapable tyranny of time and death; have suffered the pain of loss, and the more wearing, continuous pain of frustration and failure; and have had moods of unlooked-for release and peace. They have known and watched in themselves and others.
    Elizabeth Drew (1887–1965)
