Magic Bullet Suppositories are water soluble and allow the active ingredient (bisacodyl) to disperse within minutes of insertion. The Magic Bullet suppository formulation does not use an oil base (hydrogenated vegetable oil) as found in other bisacodyl-based laxatives. The oil base in these other suppositories has to melt before the bisacodyl can stimulate the bowel to contract and push out the stool. The Magic Bullet acts quickly and contains a full 10mg of bisacodyl USP.
