Droxidopa
Based on 1 Customer Validation
Droxidopa (L-DOPS; SM5688) is a potent, orally active norepinephrine precursor. Droxidopa increases standing blood pressure, ameliorates symptoms of orthostatic hypotension and improves standing ability. Droxidopa has the potential for the research of neurogenic orthostatic hypotension (nOH) and alternative ADHD (attention deficit hyperactivity disorder).

Animal Model:250-380g male Sprague-Dawley rats[2]
-
Dosage:200 mg/kg (10 mg/kg, i.p. benserazide was given to the animals at 20 or 30 min prior to L-DOPS injection)

Result:Significantly decreased hyperactivity of BZ-pretreated SHR/NCrl at 30 (P < 0.01) and 40 min (P < 0.05) post-injection, improved inattention-like behavior of SHR/NCrl, and ameliorated impulsive-like behavior of SHR/NCrl and Wistar rats.
