Sildenafil citrate (Viagra) complexes with bivalent ions
Journal of Pharmaceutical Sciences, 2006The interaction of Ca(2+)-ions with sildenafil citrate (Viagra) leads to the precipitation of a new polymorph variety of sildenafil base. Under the same conditions, Mg(2+), Zn(2+), and Cd(2+) ions form structurally related crystalline complexes of the composition Me(2+)C(28)H(34)N(6)O(11)S. Lattice parameters have been determined showing that magnesium
