Key differences
Addyi belongs to Women's Sexual Health while Tadalafil belongs to Erectile Dysfunction (ED). Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Addyi: Sexual desire is modulated by complex central nervous system pathways involving serotonin (generally inhibitory) and dopamine and norepinephrine (generally excitatory). Tadalafil: The mechanism is identical to original Cialis: tadalafil selectively inhibits PDE5 in penile and vascular smooth muscle, allowing cyclic GMP produced during sexual arousal to accumulate.
When Addyi is preferred
Addyi is indicated for the treatment of acquired, generalised hypoactive sexual desire disorder (HSDD) in premenopausal women.
When Tadalafil is preferred
Generic tadalafil shares the indications of the originator: erectile dysfunction in adult men, lower urinary tract symptoms associated with benign prostatic hyperplasia, and pulmonary arterial hypertension at adapted doses.
