This research aims is to create a promethazine HCl patch transdermal drug delivery systems with the most excellent penetration. Transdermal drug delivery can be efficiently used for the active agents which undergo rapid first pass metabolism and oral absorption is often disrupted by nausea and vomiting, hence the transdermal patches of promethazine HCl were prepared by using different penetration enhancers,  propylene glycol, oleic acid and isopropyl alcohol. The prepared formulations were evaluated for thickness, weight variation, moisture content, drug content, morphology, and in vitro permeation studies. The patch morphology studies were performed by Scanning Electron Microscopy (SEM). The amount of promethazine HCl transfered by propylene glycol  25.77 ± 3.0396 ug, isopropil alcohol 25.758 ± 2.9022 ug and oleic acid 25.017 ± 8.1300 ug. The penetration of promethazine HCl patch with oleic acid enhancer, produce the highest penetration than isopropil alcohol and propylene glycol. there was no difference in penetration using propylene glycol and isopropyl alcohol. Oleic acid is the best enhancer for preparations patch containing promethazine HCl although the amount of promethazine HCl contained is the least. The whole formulations comply with the  patch dosage requirements

Objective: The present work was aimed at preparation of transdermal patches by a solvent casting method using a varying concentration of polymers i.e. methocel (K15 and K100), ethocel (4 and 10), gelatin, chitosan, eudragit (RL and RS) grade using plasticizer (glycerin and propylene glycol).Methods: The ratio of drug to polymers and plasticizer was varied and the effect of formulation variables was studied. Prepared transdermal patches were evaluated for physicochemical properties, in-vitro permeation studies, content uniformity, primary skin irritation studies and FT-IR studies.Results: The formulated transdermal patch by using Methocel K 100 M showed good physical properties. The average weight of patches prepared using glycerin as a plasticizer were ranged from 42.33-67.00 mg and propylene glycol as a plasticizer were ranged from 40.67-67.67 mg. The percentage moisture absorption varies from 1.76 to 10.73 for patches formulated using glycerin and 2.28 to 7.97 for propylene glycol patches. The percentage moisture loss from patches prepared using glycerin was ranged from 2.75 to 11.54 and 2.87 to 12.02 from propylene glycol. The water vapour transmission rate from patches prepared using glycerin was ranged from 0.25 to 0.92 and 0.41 to 1.76. The formulated patch showed the acceptable quantity of medicament ranged from (100.20-101.05%). This result met the test content uniformity as per BP (85% to 115%). According to that, the drug was consistent throughout the patches. The formulation PGD is considered as the best formulation, since it shows a maximum in vitro drug release as 43.75 % at 24 h. The drug release kinetics studied showed that the majority of formulations was following zero order.Conclusion: In conclusion, controlled release transdermal drug delivery system patches of aliskiren can be prepared using polymer combinations, with a different plasticizer. The release rate of drug depends upon the polymer. However, release kinetics followed zero order.

Microemulsion (ME) systems are now considered of the most successful transdermal drug delivery systems. This is due to their nanodroplets size in the one hand and to their composition that enables the use of several mechanistically penetration enhancers in the same formulation on the other hand. This work summarizes the types, properties, and the merits of the use of MEs for transdermal delivery and reviews the successful studies that were performed to deliver several drugs through this important route during the past 10–12 years.
