Background: Androgenetic alopecia (AGA) is the most common cause of hair loss in men. Topical minoxidil solutions can help to treat AGA but have to be applied continuously to be effective., Objectives: A new minoxidil formulation with improved cosmetic characteristics (DC0120, Pierre-Fabre Dermatologie) was tested for noninferiority vs a comparator minoxidil product (ALOSTIL ® , Johnson & Johnson) in stimulating hair growth in men with AGA., Methods: Two 10 cm 2 areas on the scalp of each subject were randomized to receive DC0120, the comparator, or one of their corresponding vehicles, applied twice per day for 16 weeks. Nonvellus target area hair count (TAHC) was measured within treatment areas at baseline (day 1) and after 8 and 16 weeks by digital phototrichogram., Results: Two hundred and twenty subjects were included and randomized, of which 210 completed the study. The mean change in nonvellus TAHC between baseline and week 16 was +22.0 hairs/cm 2 (95% CI: 18.1; 25.9) in the DC0120 group and +20.5 hairs/cm 2 (95% CI: 16.6; 24.4) in the comparator group. The adjusted mean difference in TAHC changes between the two treatments was +1.5 hairs/cm 2 (95% CI -2.3; 5.2), with the lower 95% confidence interval above the noninferiority threshold of -7 hairs/cm 2 . This indicated that DC0120 was noninferior to the comparator. Both minoxidil treatments also increased nonvellus TAHC compared to vehicle groups at 8 and 16 weeks. No new safety signals were observed., Conclusions: DC0120 was as safe and effective as a similar marketed minoxidil product for stimulating hair growth in men with AGA., (© 2018 Wiley Periodicals, Inc.)

Numerous iron-containing preparations are available on the market; these vary in dosage, salt, chemical state of iron (ferric or ferrous) and in the iron delivery process (immediate or prolonged-release). Tardyferon® is a prolonged-release tablet containing 80 mg ferrous sulphate. The formulation has recently been modified; changes to the excipients which constitute the inert formulation matrix have allowed a decrease in tablet size for easier swallowing. The aim of this multicenter open-label study was to characterize the serum pharmacokinetics of iron in non-pregnant women aged 23-45 years with iron deficiency anaemia (IDA) following single oral administration of 160 mg Tardyferon® under fasting conditions. Blood samples were collected from the 29 participants before dosing and until 24 h post-dosing. Serum iron concentrations were determined using a routine colorimetric analytical method; pharmacokinetic parameters were derived using a non-compartmental approach. In these patients, median time to maximum serum concentrations (Tmax) was 4 h. Serum profiles were consistent with prolonged release; iron levels were elevated up to 12 h after dosing, with mean C 12h still more than 7 times higher than baseline (C T0 ), and mean C 2h and C 8h representing 69.7% and 81.9% of the C max , respectively. In vitro dissolution testing performed on the clinical batch also demonstrated prolonged release of iron from this formulation. A single oral dose of 160 mg Tardyferon® administered under fasting conditions to this target population resulted in a long-lasting release of iron in the gastrointestinal tract, leading to optimal iron absorption. Moreover, Tardyferon® was well tolerated., Competing Interests: Conflict of Interest: Dr A.
