Vigora is an Indian tablet brand of sildenafil citrate, dosed at 100 mg and supplied in strips of four. Like the rest of this group it is an oral PDE5 inhibitor and not a hormone: the class was developed for erectile dysfunction and acts on the smooth muscle of blood vessels.
Where it differs from the Kamagra-branded items is only in origin and presentation, meaning a separate manufacturer, separate foil and separate registration. The choice between them usually comes down to which name a buyer already recognises. The tablet itself is the familiar coated type, swallowed whole.
