Figure 7From: Hydrogels containing redispersible spray-dried melatonin-loaded nanocapsules: a formulation for transdermal-controlled deliveryProfiles of melatonin release. These profiles are from (a) nanocapsule suspension in comparison to the melatonin solution, (b) hydrogels (G-M or G-NC), (c) spray-dried powders (D-NC-L and D-NC-M), and (d) hydrogels prepared with spray-dried powders (G-NC-L and G-NC-M).Back to article page
