Prostanoids may be involved involved in inhibition brand name viagra platelet aggregation and white cell adhesion and recent data suggest that prostanoids and transforming growth factor 1 (TGF 1) may have a role in modulation of collagen synthesis and in the regulation of brand name viagra intracellular concentration of cAMP.
