# Magistral Galenic Preparations in Modern Dermatology: Our Top 10 Picks for Bridging Therapeutic Gaps

## TL;DR

This paper highlights the importance of customized magistral formulations in dermatology for treating conditions where standard products fall short.

## Contribution

The paper identifies ten magistral formulations that address therapeutic gaps in dermatology not covered by commercial products.

## Key findings

- Benzyl benzoate and precipitated sulfur show superior efficacy in pediatric scabies compared to permethrin.
- Hoffmann Paste and Lime Liniment effectively manage acute inflammatory dermatoses by neutralizing acidity.
- Customized formulations like Burow’s and Silver Nitrate provide targeted biocidal activity absent in standard topicals.

## Abstract

Background/Objectives: Topical treatment efficacy is fundamentally dependent on effective delivery of the active pharmaceutical ingredient and its compatibility with the compromised skin barrier. Many commercially available industrial formulations contain poorly tolerated excipients or lack essential therapeutic combinations, frequently leading to complex polypharmacy and reduced patient adherence. In contrast, magistral galenic preparations offer a degree of therapeutic personalization unmatched by standardized products, positioning the compounding laboratory as a strategic resource in dermatological care. This analysis aims to identify and evaluate ten indispensable magistral formulations selected based on their high clinical frequency and the absence of equivalent, globally available commercial alternatives. Materials and Methods: Each formulation was according to four strategic pillars: (i) dosage customization, (ii) excipient modification (removing allergens like parabens or fragrances), (iii) synergistic ingredient association, and (iv) vehicle optimization. The dermatological conditions addressed include pediatric scabies, melasma, hidradenitis suppurativa, and autoimmune mucosal diseases. Key selections include Kligman’s formula for hyperpigmentation and personalized trichological preparations. Results: The identified “top 10” magistral formulation reveals significant gaps within the standardized pharmaceutical market. In pediatric scabies (specifically patients < 15 kg), benzyl benzoate and precipitated sulfur demonstrate superior efficacy over permethrin, addressing emerging resistance patterns. For acute inflammatory dermatoses, Hoffmann Paste and Lime Liniment provide effective protective barriers while neutralizing local acidity. Antiseptic and astringent solutions, including Burow’s and Silver Nitrate (AgNO3) offer targeted mechanisms and biocidal activity, often absent in standardized topicals. Furthermore, specialized adhesive oral pastes for autoimmune conditions minimizing systemic absorption and associated risks. Conclusions: Magistral compounding represents a cornerstone of precision medicine in dermatology enabling tailored therapies that bridge critical gaps left by standardized formulations, particularly in complex cases and vulnerable populations.
