Topical excipients play a crucial role in the formulation of pharmaceutical products intended for external use, such as creams, ointments, gels, and transdermal patches. These excipients serve various purposes, including enhancing drug solubility, ensuring stability, improving drug release, and providing desirable sensory properties.
Pharma Excipients
Topical Excipient
Transcutol® P Containing SLNs for Improving 8-Methoxypsoralen Skin Delivery
Topical psoralens plus ultraviolet A radiation (PUVA) therapy consists in the topical application of 8-methoxypsoralen (8-MOP) followed by the skin irradiation with ultraviolet A radiation. The employment of classical 8-MOP vehicles in topical PUVA therapy is associated with poor skin deposition and…

Film forming systems for topical and transdermal drug delivery
Methyl ester derivatives of alginic acid have been evaluated as potential multifunctional excipients for pharmaceutical direct compression. The use of alginic acid as an excipient in tablet formulation is limited because of certain drawbacks such as low tablet hardness and poor compressibility. The…

Transdermal delivery of peptide and protein drugs
Peptide and protein drugs (PPDs) that possess the advantages of high specificity and tolerance, and low immunogenicity can effectively treat diabetes, osteoporosis, cancer, and genetic defects. However, the high molecular weight and poor stability of PPDs lead to low bioavailability in oral delivery…

Effects of Formulation Excipients on Skin Barrier Function in Creams Used in Pediatric Care
Semisolid dosage forms are recommended for the dermal care of babies and children.
If we look at the ingredients of these preparations, there are still many cases in which there are
substances (occlusive agents, preservatives) that no longer meet certain requirements of the modern
age, so it is…
