Promoting Activity of Terpenes on Skin Permeation of Famotidine.

Famotidine (FMT) is a competitive histamine-2 (H2) receptor antagonist that inhibits gastric acid secretion for the treatment of Gastroesophageal reflux disease. To study the promoting effect and mechanism of terpenes, including l-menthol, borneol, and geraniol, as chemical enhancers, FMT was used as a model drug. Attenuated total reflectance-Fourier transform IR spectroscopy (ATR-FTIR) and differential scanning calorimetry (DSC) were used to explore the effects of terpenes on the skin.

MRI Monitoring of the Mixed State of Admixtures Consisting of Moisturizing Cream and Steroid Ointment during the Mixing Process by a Revolution/Rotation-Type Hybrid Mixer.

The admixture of a steroid ointment and a moisturizing cream is frequently prescribed to patients suffering from atopic dermatitis. For the mixing operation, a revolution/rotation-type hybrid mixer is widely used in pharmacy. The purpose of this study was to monitor the mixed state of the admixtures during the mixing process of the hybrid mixer.
