How does Granpidam work?
PAH is a debilitating disease where there is severe constriction (narrowing) of the blood vessels of the lungs. This leads to high blood pressure in the vessels taking blood from the heart to the lungs and reduces the amount of oxygen that can get into the blood in the lungs, making physical activity more difficult. The active substance in Granpidam, sildenafil, belongs to a group of medicines called
How has Granpidam been studied?
Because the effectiveness and safety of sildenafil in PAH is already well established, studies in people have been limited to tests to determine that it is bioequivalent to another authorised sildenafil- containing tablet. Two medicines are bioequivalent when they produce the same levels of the active substance in the body. In this case Granpidam was not compared with the reference product Revatio, but with Viagra. This was considered acceptable since Revatio and Viagra have the same composition and are made in the same way by the same manufacturer.
What are the benefits and risks of Granpidam?
Because Granpidam is a generic medicine, its benefits and risks are taken as being the same as the reference medicine’s.
Why is Granpidam approved?
The Agency’s Committee for Medicinal Products for Human Use (CHMP) concluded that, in accordance with EU requirements, Granpidam was considered to be comparable to Revatio. Therefore, the CHMP’s view was that, as for Revatio, the benefit of Granpidam outweighs the identified risk. The Committee recommended that Granpidam be approved for use in the EU.
What measures are being taken to ensure the safe and effective use of Granpidam?
Recommendations and precautions to be followed by healthcare professionals and patients for the safe and effective use of Granpidam have been included in the summary of product characteristics and the package leaflet.
