The paper summarizes the present state of standard prescriptions for the formulation of suspensions for dermal administration in the Czech Republic and compares it with the NRF (Neues Rezeptur-Formularium in Deuscher Arzneimittel-Codex) standard prescriptions. The analysis of medical prescriptions for suspensions for dermal administration dispensed in the pharmacies of the Czech Republic has revealed that 18.8 % of the prescriptions were for 50% suspension of zinc(II) oxide in sunflower oil. This preparation should therefore become a candidate for standardization as a monograph in the national part of the Czech Pharmacopoeia.

Human mesenchymal stromal cells (MSCs) are attractive for both medical practice and biomedical research. Nonfreezing short-term storage may provide safe and simple transportation and promote the practical use of MSCs. We aimed to determine the duration of efficient storage at ambient temperature (22°C) of human dermal MSCs in different three-dimensional organization and to investigate the role of cell metabolic mode in the resistance to the ambient storage damaging factors.

Adhesiveness of dermal patches can be modified in the presence of active substances. The effect is more complex when liquid components are also present in the matrix. Commercial grade pressure sensitive adhesive (PSA) polyacrylates (three types) and silicones (two types) were used to prepare adhesive matrices and liquid additives were propylene glycol, polyoxyethylene glycol, isopropyl myristate, triacetin, triethyl citrate or low viscosity silicone oil.

Ablative fractional laser-assisted drug delivery has gained attention as a promising method for enhancing dermal drug absorption and improving therapeutic outcomes in dermatological conditions, particularly for hypertrophic and keloid scars. However, despite the growing number of clinical trials and case reports supporting its efficacy, there remains a scarcity of robust evidence on the topical bioavailability and dermato-pharmacokinetics of drugs in human subjects. This study aimed to examine the enhancement of triamcinolone acetonide (TAC) bioavailability following treatment with a fractional Erbium-Doped Yttrium Aluminum Garnet (Er: YAG) laser.

Hard-to-heal wounds represent a global and growing medical and economic burden. Skin autografting is a useful treatment option but is often limited by donor site morbidity, logistical considerations, and grafting success in compromised wound beds. Combining autologous skin cell suspension (ASCS) technology with minced dermal grafts can allow for dermal elements and epithelial healing as well as closed donor sites.

Introduction: The combination of hyaluronic acid (HA) fillers and polydioxanone (PDO) thread lifting is gaining popularity for mid-face rejuvenation, especially among the Asian population. Despite the common use of these techniques, there is a paucity of long-term studies assessing their combined efficacy and safety. This study aims to evaluate the efficacy and safety of combined HA filler and PDO thread treatment for mid-face rejuvenation over a 24-month period in a Korean population.
