This study found that two eco-friendly analytical methods for quantifying Finasteride and Tadalafil in a new dosage form were effective, green, and suitable for quality control.

This study found that a modest increase in dietary zinc over six months resulted in a detectable increase in sulfur and zinc counts in individual hairs, suggesting a non-invasive method to monitor zinc intake effects.

In this study, researchers developed an in-situ gel formulation of antibacterial Levofloxacin for the eye, which showed prolonged drug release, increased residence time, and effective antibacterial action, suggesting it may be a safe and effective ocular delivery system for antibiotics.

This study demonstrated that FT-Raman spectroscopy is effective for identifying finasteride polymorphs in tablets and detecting the presence of alternative polymorphs down to about 15% concentration.

This study found that increasing a drug's lipophilicity and adding ethanol to the donor phase can enhance its delivery to the hair follicle, although the precise transport mechanism remains unclear.

This study successfully used noninvasive bioluminescence imaging to monitor hair generation in vivo after transplanting hair follicle stem cells in mice.

In this case series, four adults developed severe, disabling multisymptom illness potentially linked to fluoroquinolone use, which persisted and progressed even after discontinuation of the drug.
