Abstract:
Background: Oral strip is very similar to thin strip of postage stamp in shape, size and
thickness. The strip is designed to be placed on the tongue or any oral mucosal tissue which immediately
gets wet and hydrated after being in contact with the saliva. Desloratadine is one of the better-
known second-generation antihistamines that has been studied for being effective in relieving
the allergic nasal and skin symptoms.
Objective: The aim of this study is to develop desloratadine orodispersible film (ODF) with fast
disintegration time and suitable mechanical strength to treat allergic symptoms in geriatric patients
in order to increase compliance and convenience.
Methods: Solvent casting method using hydroxypropyl methylcellulose (HPMC) as the film forming
polymer was applied. Polyethylene glycol 400 (PEG 400) and glycerol (Gly) were used as the
plasticizers and citric acid (CA) was used as saliva stimulating agent. The resultant films were
evaluated for disintegration time, folding endurance, surface pH, weight variation, thickness, surface
morphology using scanning electron microscopy, drug content, content uniformity, moisture
loss, moisture uptake, and drug-excipient compatibility using DSC and FT-IR.
Results: All the selected films started to disintegrate in less than 14 seconds. Selected optimum
films exhibited good mechanical properties with a folding endurance value greater than 100. The
uniformity in weight, thickness, and drug content in the selected films was obtained. Surface pH
was within the normal range (6.4 - 6.8). A smooth surface of the films was obtained and drugexcipient
compatibility was proved using DSC and FT-IR. The dissolution test was done for optimum
film formulations by simulating the oral cavity physiological conditions using the conventional
dissolution test apparatus. More than 87% of the drug was released by the 4th minute.
Conclusion: Orodispersible film of desloratadine was successfully prepared by solvent casting
method in order to improve the disintegration/dissolution of the drug in oral cavity and hence better
patient compliance and effective therapy.
