The aim of the present study was to develop a transdermal system for controlled delivery of melatonin combining three strategies: nanoencapsulation of melatonin, drying of melatonin-loaded nanocapsules, and incorporation of nanocapsules in a hydrophilic gel. Nanocapsules were prepared by interfacial deposition of the polymer and were spray-dried using water-soluble excipients. In vitro drug rel...
Alaptide, (S)-8-methyl-6,9-diazaspiro[4.5]decan-7,10-dione, is an original Czech compound; in this paper it is used as an excipient. The investigation deals with the affection of the permeation of indomethacin through full-thickness pig ear skin using a Franz diffusion cell from the donor vehicle of propylene glycol/water (1:1) using nanonized alaptide as a potential transdermal permeation enha...
Elastic liposomes (EL) are some of the most versatile deformable vesicular carriers that comprise physiologically biocompatible lipids and surfactants for the delivery of numerous challenging molecules and have marked advantages over other colloidal systems. They have been investigated for a wide range of applications in pharmaceutical technology through topical, transdermal, nasal, and oral ro...
Clinical benefits, industry interest, regulatory precedence, and strong market potential have made transdermal research the fastest growth area in drug delivery. As most drugs permeate poorly through skin, a major challenge is achieving the therapeutic level by enhancement of permeation rate. Iontophoresis, utilizing a minimal amount of current, is found to affect the skin permeation process dr...
An ibuprofen-loaded nanostructured lipid carrier (IBU-NLC) was developed for enhanced skin penetration to improve the treatment of osteoarthritis and other musculoskeletal diseases. The mean particle size was 106 nm, with a spherical morphology, a smooth surface, and a zeta potential of -18.4 mV. X-ray diffraction studies revealed the amorphous state of the lipid matrix. Both Raman spectroscopy...
oral epigallocatechin gallate supplementation in hairless rats. Mitriaikina and Müller-Goymann (Skin Pharmacol Physiol 2009; 22: 142–150) report about the permeation of non-diluted and diluted betamethasone valerate in different formulations. They were able to show that the permeation rate can be differentiated in isolated human stratum corneum and artificial skin constructs. The differences in...
The present study was undertaken to develop a suitable transdermal matrix patch of Metoprolol tartrate with different proportions of polyvinyl pyrrolidone (PVP) and chitosan crosslinked with glutaraldehyde (GA). The prepared transdermal patches were subjected to different physicochemical evaluations such as thickness, tensile strength, folding endurance, drug content, swellability, surface pH, ...
Transdermal drug delivery system is a non-invasive and an efficient method that provides sustained release and delivers therapeutics to target site. This system can improve the therapeutic efficacy and safety of the drugs, keep the plasma level of the drug constant, prevent the hepatic first pass metabolism and is convenient and pain-free self-administration for patients. Despite the many advan...
The combination of calcipotriol with methotrexate can strengthen the topical therapy for psoriasis. The aim of the present study was to evaluate the potential of nanostructured lipid carriers (NLCs) loaded with lipophilic calcipotriol and hydrophilic methotrexate as topical therapy. NLCs composed of Precirol ATO 5 with various amounts of squalene as the liquid lipid were prepared. The particle ...
In vitro permeation studies were done using modified Franz diffusion cell through rabbit skin and silicone membrane utilizing different ratios of oleic acid with diclofenac diethylamine (DDA) in normal saline and methanol mixture during present study. Solubility studies indicated linear increase in drug solubility with carrier concentration. The enhancing effect of all the enhancer’s ratios was...
