Effects of an oral contraceptive containing drospirenone on bone turnover and bone mineral density.
To compare the effects of a new 21-day combined oral contraceptive containing 30 microg ethinyl/estradiol plus 3 mg drospirenone with a 21-day preparation containing 30 microg ethinyl/estradiol plus 75 microg gestodene on bone turnover and bone mineral density in young fertile women.. A randomized, controlled trial was conducted with healthy fertile women treated with 30 microg ethinyl/estradiol plus 3 mg drospirenone (group A; n = 24), 30 microg ethinyl/estradiol plus 75 microg gestodene (group B; n = 24) and healthy controls (group C, n = 23). At 3, 6, 9, and 12 months of the study, serum and urinary calcium, osteocalcin, urinary pyridinoline, and deoxypyridinoline were measured. At baseline and after 12 months, lumbar bone mineral density was determined by dual-energy X-ray absorptiometry.. In groups A and B, urinary pyridinoline and deoxypyridinoline at 6, 9, and 12 months were significantly reduced in comparison with basal values and group C (P < .05). Pyridinoline and deoxypyridinoline levels were lower in group A than in group B throughout the study, but not significantly. In group A serum calcium levels were significantly increased after 6 months. At 12 months, no significant difference was detected in lumbar bone mineral density values among the 3 groups and in comparison with basal values.. Both combined oral contraceptives exert a similar positive influence on bone turnover and bone-sparing effect in young postadolescent women.

Effects of a low-dose and ultra-low-dose combined oral contraceptive use on bone turnover and bone mineral density in young fertile women: a prospective controlled randomized study.
In this prospective, controlled, randomized study, we compared the effect of a low-dose 21-day combined oral contraceptive (COC) containing 20 microg ethinyl estradiol (EE) and 75 microg gestodene (GTD) (Group A; n = 19) with an ultra-low-dose 24-day COC containing 15 microg EE and 60 microg GTD (Group B; n = 18) on bone turnover and bone mineral density (BMD) in young, fertile women. Nineteen healthy fertile women were used as untreated controls (Group C). At 3, 6, 9 and 12 months of the study serum osteocalcin (BGP), urinary pyridinoline (PYD) and deoxypyridinoline (D-PYD) were measured in all subjects. At baseline and after 12 months BMD was determined at lumbar spine by dual-energy X-ray absorptiometry in all patients. In both Groups A and B, urinary levels of PYD and D-PYD at 6, 9 and 12 months, were significantly reduced in comparison with basal values and with control subjects (p < 0.05). No significant differences in urinary PYD and D-PYD levels were observed between Groups A and B during the entire period of treatment. At 12 months, no statistically significant difference in spinal BMD values was detected between the three groups and in comparison with basal values. The present study suggests that the two COCs could exert a similar positive effect on bone turnover in young postadolescent women, without any significant and appreciable modification of BMD.

Evidence that treatment with monophasic oral contraceptive formulations containing ethinylestradiol plus gestodene reduces bone resorption in young women.
The aim of the study was to evaluate if a pill containing the same dose of the same type of progestin compound (gestodene, GES, 75 microg) but different doses of ethinylestradiol (EE2) (20 or 30 microg) differently influences specific markers of bone resorption (urinary levels of pyridinoline (PYR) and dexoxypyridinoline (D-PYR)). During the 12 months of the study a significant decrease of urinary levels of PYR and D-PYR was found in 2 groups of young post-adolescent women taking the pills with 20 and 30 microg of EE2 in comparison with control women (subjects of the same age group with normal menstrual cycle who did not use contraception). In women taking pills with 20 or 30 microg EE2, the levels of sex hormone-binding globulin (SHBG) significantly increased during treatment in comparison with baseline, whereas in the same time period no changes occurred in control women. These findings suggest that similar to the pill containing 30 microg EE2, the lower dosage of the EE2 pill (20 microg) is also capable of reducing bone resorption. Twenty and 30 microg EE2 pills exert the same biological estrogenic effect. In fact, SHBG levels significantly increased with both pills. However, an additional effect of the progestin compound that could act directly on progestin or estrogen receptors of bone cannot be excluded. Since contraception with a pill containing the lowest estrogen dose is associated with the lowest incidence of side effects, these findings further suggest a pill containing 20 microg EE2 for young post-adolescent women would be the best choice..
