Topical medications derived from traditional medicines play a crucial role in dermatological treatment, often serving as the primary therapeutic approach. The underlying causes of dermatological conditions may include external factors such as wind, cold, dampness, heat, parasites, or internal imbalances such as stagnation of qi, blood stasis or deficiencies in liver and kidney function. Treatment methods in traditional medicine may incorporate remedies, surgical interventions, or a combination of both.

This study outlines a nanotechnology-based method to enhance its solubility and absorption of rosuvastatin. The process entails the formulation of rosuvastatin nanoparticles through a combination of precipitation and ultrasonic techniques. Rosuvastatin is initially dissolved in an organic solvent, such as acetone, and subsequently mixed with an aqueous phase containing stabilizers like Poloxamer 407 or PVP to induce precipitation. Ultrasound reduces particle size to 50-200 nm.

OECD guidelines were applied. Mice were divided into 7 groups consisting of 30 females and 10 males each. In which, the control group received the solvent, only females or males in 4 other groups were taken the testing samples (32), and both females and males of 2 remain groups were given those samples. Mice were given oral samples at a dose of 288 or 576 mg/kg/day × 7 consecutive days depending on individual group.
