Not really. Dragons get unique versions of all of the Shouts that act as spells, so if you can drain a Dragon of all it's Magicka it becomes incapable of Shouting. That's what makes Shock Magic particularly effective against Dragons, it forces them into melee range and for a Mage, well that's fine as long as you aren't anywhere near it. Here's the UESP page description just because it says it better thann I do.
Dragons have their own unique "dragon" versions of the Fire Breath, Frost Breath, Unrelenting Force, and Drain VitalityDG shouts, and their Fireball and Ice Storm spells are treated like shouts as well. Dragons rely on their magicka reserves to use these shouts, which means that if a dragon's magicka is drained, it will not be able to use its shouts. The base damage for all the dragons detailed below is 25 (with the exception of the Skeletal Dragon), and their tail swipe attacks will stagger all enemies in a large area. - UESP, Dragons
