Compatibility Assessment of Novel Orodispersible Film Vehicle for Personalized Medicine with Selected Active Pharmaceutical Ingredients

Orodispersible films (ODFs) are solid pharmaceutical forms for rapid local or systemic release of active ingredients. They are formed by a water-soluble polymer film that hydrates rapidly, adhering and dissolving immediately when placed on the tongue or in the oral cavity. In this paper, we describe the compatibility and disintegration times of compounded ODFs using OrPhyllo(TM), a new ready-to-use-vehicle, and APIs from different pharmacological classes, such as 5-hydroxytryptophan (5-HTP) 50 mg, bromopride 5 mg, coenzyme Q10 20 mg, melatonin 3 mg, resveratrol 5 mg, tadalafil 10 mg, vitamin B12 1 mg, or vitamin D3 2000 UI. ODFs were compounded and, subsequently, the samples were assayed using HPLC at initial (t = 0), 7 days (t = 7), 14 days (t = 14), 30 days (t = 30), 60 days (t = 60), 90 days (t = 90), 120 days (t = 120), 150 days (t = 150), and 180 days (t = 180) after compounding. Given the percentage of recovery of the APIs within the films, the beyond-use date of the final products (API + vehicle) was at least 90 days for vitamin D3, 150 days for bromopride and 5-HTP, and 180 days for coenzyme Q10, tadalafil, vitamin B12, resveratrol, and melatonin, when stored at room temperature. The average disintegration time was 46.22 s. This suggests that the OrPhyllo(TM) vehicle is suitable for compounding ODFs with APIs from different pharmacological classes, with good compatibility and fast disintegration.
