Pharmaceutical Considerations of Translabial Formulations for Treatment of Parkinson’s Disease: A Concept of Drug Delivery for Unconscious Patients

The goal of the present research was to isolate a biopolymer from Phaseolus vulgaris (P. vulgaris) and Zea mays (Z. mays) plants and used it to construct Resveratrol (RES)-loaded translabial films.Biopolymers were extracted from P. vulgaris and Z. mays seeds using a simple process. Separated biopolymers, sodium carboxymethylcellulose (SCMC) and tragacanth were subjected to formulation development by incorporating RES-loaded translabial films. The Fourier-transform infrared spectroscopy (FTIR), physical appearance, weight, thickness, folding endurance, swelling index, surface pH, percent moisture absorption, percent moisture loss, vapor transfer rate, and content uniformity of the translabial films were examined. The mucoadhesive, ex-vivo permeation, in vivo and stability studies, were performed.The results showed that RES-loaded translabial films produced from P. vulgaris and Z. mays biopolymers exhibited exceptional mucoadhesive, stability, and permeation properties. Results revealed that the best formulations were prepared from a combination of biopolymer (P. vulgaris C or Z. mays C) with tragacanth. Formulations with tragacanth revealed good swelling and thus permeation profiles. In vivo release of TL 11 was found to be 24.05 ng/ml in 10 hours and it was stable enough at 45°C.This research suggested that RES-loaded translabial formulations can be potentially used for the treatment of Parkinson's disease with good patient compliance to geriatric and unconscious patients.
