Lazanda (fentanyl) nasal spray is a liquid formulation of fentanyl citrate intended for intranasal transmucosal administration. The product consists of a practically clear to clear, colorless, aqueous solution of fentanyl citrate in a glass multidose container to which is attached a metered-dose nasal spray pump with a visual and audible spray counter. Each actuation is designed to deliver a spray of 100 mcL of solution containing 100 mcg or 400 mcg fentanyl base, respectively. This enables doses of 100 mcg or 400 mcg to be administered using a single spray into one nostril (1 spray) and 200 mcg or 800 mcg to be administered using a single spray into both nostrils (2 sprays).
