Nausea and vomiting are symptoms associated with a lot of diseases and oral tablets may be unprofitable for patients especially those suffering from nausea and vomiting. Therefore, this study aimed to formulate a new meclizine and pyridoxine combination formula for chewable tablets and provide rapid drug absorption and decrease motion sickness. The new chewable formulation has been prepared to provide fast action, is more acceptable, and could be used for all age categories. Seven trials haves been carried out to prepare to find the suitable one where formula 7 of the chewable gum preparation exhibited good taste and hardness, while the gelatin formulation give an accepted formula after four trials with better taste and good acceptance. The prepared formulations give a dissolution profile of meclizine (95.53–102.8%) and pyridoxine (99.25 ± 115%) and assay (98 + 0.05–99.3 ± 0.8%) for meclizine and (97 ± 0.9–100.0 ± 0.08%) for the pyridoxine in three prepared formulations of chewable tablets. Followed by the evaluation, the formulation and testing them on human volunteers are carried out to confirm their effect to ensure acceptance and fast actions. The finding is promising for preparing a new route of administration of meclizine and pyridoxine combination to be used in the market. [ABSTRACT FROM AUTHOR]

Meclizine is antihistamine and is used in combination with pyridoxine to treat motion sickness. The in-silico study of meclizine prediction studied showed that meclizine has anti-eczema activity with possible activity 95. This research aimed to explore the anti-eczema activity of meclizine. Therefore, five formulations of meclizine ointment have been prepared using different bases (white base, simple ointment base, hydrophilic petrolatum base, hydrophilic, and emulsifying ointment bases). The efficiency of meclizine ointment has been evaluated by testing the physical compatibility and stability, homogeneity and irritant effect, absorbance and spreadability, chemical identification, calibration curve, drug content (assay), and dissolution test. This is followed by evaluating the ointment's effectiveness on volunteers and molecular docking. Five creams trials have been prepared, and two formulas (F3, and F5) have been selected for further evaluation. The formulas three and five (F3, F5) have passed the physical and chemical tests and showed compatibility, homogenous, absorbed, non-irritant, and stable with calibration curve (R = 0.9999). Then, the F3 formula was selected by testing them on seven volunteers after evaluating the irritant test. Four of the volunteers showed excellent recovery, and three of the volunteers suffered from uncomforting feelings and the formation of new pills. Therefore, F5 has been tested by eight volunteers that contain high oleaginous activity; five showed an excellent recovery, while three of the volunteers showed no difference. According to that, F5 is more efficient for eczema patients than F3, and Meclizine showed promising activity as an anti-eczema that requires further evaluation in the future. [ABSTRACT FROM AUTHOR]
