The recent approval of lidocaine hydrochloride and epinephrine combined iontophoretic patch (Lidosite Vysteris Inc.) for localized pain treatment by FDA has invigorated the gaining interest in iontophoretic drug delivery systems for the transdermal delivery of drugs. This technique of facilitated movement of ions across a membrane under the influence of an(More)
The aim of the present study is to develop and evaluate microemulsion formulations for Terbinafine (TB) with a view to enhance its permeability through the skin and provide release for 24 h. Various o/w microemulsions were prepared by the spontaneous emulsification method. Oleic acid was chosen as the oil phase, Caprylo caproyl macrogol-8- glyceride(More)
The purpose of the present study is to develop and evaluate the potential of nanoemulsions for increasing the solubility and the in vitro transdermal delivery of carvedilol. Pseudoternary phase diagrams were developed and various nanoemulsion formulations were prepared using oleic acid and isopropyl myristate (IPM) (1:1) as the oil, Tween 80 as surfactant,(More)
Silymarin, a flavonolignan from the seeds of ‘milk thistle’ (Silybum marianum), has been widely used from ancient times because of its excellent hepatoprotective action. It is a mixture of mainly three flavonolignans, viz, silybin, silidianin, and silychristine, with silybin being the most active. Silymarin has been used medicinally to treat liver(More)
By many estimates, up to 40 percent of new chemical entities discovered by the pharmaceutical industry are poorly soluble or lipophilic compounds. Solubilization of hydrophobic drugs with low aqueous solubility has been a major area of interest in recent years. Various solubilization techniques involve the use of co-solvents and surfactants along with pH(More)
