The apical layer of the skin called the <i>stratum corneum</i> is the most dominant obstacle in the transdermal drug delivery, which restricts the passage of drugs across the skin.

Various vesicular systems have been developed and utilized for the transdermal delivery of many drugs.

The combined presence of ethanol and terpenes provides exceptional flexibility to the vesicles and improves the permeation across the barrier offered due to the <i>stratum corneum</i> as both ethanol and terpenes act as permeation enhancers.

The oral bioavailability of Pemigatinib is constricted due to its limited solubility at physiological pH. It is essential to develop a novel formulation of Pemigatinib to improve the intrinsic solubility and to reduce the pharmacokinetic variability. Self-nanoemulsifying drug delivery system is an effective, smart and more adequate formulation approach for poorly soluble drugs.

The composition of oil, surfactant and co-surfactant was identified using phase diagrams and further adjusted by simplex-lattice design.

The drug release rate is directly proportional to the concentration of the drug. The drug release from the insoluble matrix is a square root of time-dependent Fickian diffusion process.
