Mechanisms compared
Lumigan: Bimatoprost is a prostamide analogue that increases aqueous humour outflow through both the trabecular meshwork and the uveoscleral pathway, lowering intraocular pressure. Norethindrone: Norethindrone binds to progesterone receptors and exerts progestational effects: thickening cervical mucus, suppressing the LH surge, thinning the endometrium and inhibiting ovulation (at sufficient doses).
When the comparison makes sense
