Aygestin and Tadalafil are used in very different patients, and the points in common are limited. The main shared element is that both meet regulatory standards for efficacy and safety and benefit from pharmacist oversight.
Key differences
Aygestin 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
Aygestin: Norethindrone binds to progesterone receptors and exerts progestational effects: thickening cervical mucus, suppressing the LH surge, thinning the endometrium and reducing endometrial implant activity in endometriosis. 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 Aygestin is preferred
Aygestin is approved for endometriosis-associated pain, abnormal uterine bleeding due to hormonal imbalance, and secondary amenorrhoea.
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.
