ADQUEY vs ORTHO-NOVUM 7/14-21
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ADQUEY (aducanumab) is a human monoclonal antibody that selectively targets aggregated forms of amyloid beta (Aβ), including soluble oligomers and insoluble fibrils, reducing Aβ plaques in the brain. The exact mechanism linking Aβ reduction to clinical improvement is not fully established.
Combination estrogen-progestin contraceptive: suppresses gonadotropin release, inhibits ovulation, thickens cervical mucus, alters endometrial receptivity.
