Transdermal Drug Delivery of Antihypertensive Drugs Using Ethosomal Gels

Abstract

A naturally occurring polyphenolic flavonoid with limited water solubility and bioavailability, silymarin (SM) has lipid-lowering and antidiabetic properties. The goal of the current study was to create an anti-psoriatic gel formulation using silymarin. The goal of this research project is to lessen the suffering and distress experienced by psoriasis sufferers. To get over these issues, SM-incorporated ethosomes (ETO) were created and refined using the cold approach with a 32 complete factorial design in the present study. The physical appearance, size distribution, negative charge potential, morphological study, powder crystallinity, phase transition behavior, and percentage of drug entrapment were all assessed during the synthesis and evaluation of the SM-ETO. After optimization, SM-ETO was added to a carbapol 934p-containing gel and tested for drug content, rheology, pH, and in vitro drug release. The findings showed that at 2–8°C, SM-ETO batches did not exhibit phase separation. The batch E8 had a vesicular size of 168 nm, a 0.367 polydispersity index, a -0.49 mV zeta potential, and an 89.67% drug entrapment rate. A morphological analysis showed lengthy, round vesicles. X-ray diffraction analysis shows that SM powder is amorphous. A large pH range of 6.94 to 7.18 was found in a prepared gel. Additionally, it showed 96.32 to 98.45% drug content and 9.187 (cp) viscosity. 96, 97, 94, and 98 percent SM release from gel batches was shown by in vitro drug release. The thorough results examined the created gel's improved solubility and bioavailability, indicating that it may be used as a nanocarrier to deliver SM for upcoming therapeutic applications. In summary, it can be said that: Ethosomal gel formulation of Silymarin has been effectively created with the use of formulation development technique.
