METHODS USING COMBINED ORAL CONTRACEPTIVE COMPOSITIONS WITH REDUCED CARDIOVASCULAR EFFECTS
Described are combined oral contraceptive compositions with reduced cardiovascular effects and methods using them. In some embodiments, the methods relate to contraceptive methods or methods for treating dysmenorrhea with reduced cardiovascular effects, such as reduced venous thromboembolism (VTE) risk. The methods comprise administering to a female subject an effective amount of an estetrol component and a progestogenic component. The methods enjoy a favourable profile for thromboembolism compared to currently available methods which employs contraceptives from the so-called second, third or fourth generation.
1 . A contraceptive method having a reduced risk of venous thromboembolism (VTE), comprising administering to a female subject an amount of estetrol and drospirenone, to reduce the risk of venous thromboembolism associated with the use of drospirenone.
2 . The method of claim 1 , wherein the estetrol is administered at a daily dose of from 1 mg to 40 mg.
3 . The method of claim 1 , wherein the estetrol is administered at a daily dose of from 5 mg to 25 mg.
4 . The method of claim 1 , wherein the drospirenone is administered at a daily dose of from 0.5 mg to 10 mg.
5 . The method of claim 1 , wherein the drospirenone is administered at a daily dose of from 1 mg to 4 mg.
6 . The method of claim 1 , wherein the method is a combined administration method with an administration-free interval of about 7 days.
7 . The method of claim 1 , wherein the method is a combined administration method with an administration-free interval of about 4 days.
8 . The method of claim 1 , wherein the estetrol component is estetrol monohydrate.
9 . The method of claim 1 , wherein the estetrol is administered at a daily dose of about 15 mg.
10 . The method of claim 9 , wherein the drospirenone is administered at a daily dose of about 3 mg.
11 . The method of claim 1 , wherein the estetrol is formulated in an oral dosage unit that optionally further comprises the drospirenone.
12 . The method of claim 11 , wherein the oral dosage unit is formulated to provide a daily dose of the estetrol, and drospirenone, if present.
13 . The method of claim 1 , wherein the VTE risk is lower than the VTE risk associated with a combination of 20 μg ethinylestradiol and 3 mg drospirenone.
