TGA investigates reports received by it to determine any necessary regulatory action. · To report a problem with a medicine or medical device, please see the information on the TGA website <http://www.tga.gov.au>. About AusPARs · An Australian Public Assessment Record (AusPAR) provides information about the evaluation of a prescription medicine and the considerations that led the TGA to approve or not approve a prescription medicine submission. · AusPARs are prepared and published by the TGA. · An AusPAR is prepared for submissions that relate to new chemical entities, generic medicines, major variations, and extensions of indications. · An AusPAR is a static document, in that it will provide information that relates to a submission at a particular point in time. · A new AusPAR will be developed to reflect changes to indications and/or major variations to a prescription medicine subject to evaluation by the TGA.
