Oral contraceptive steroids

Since the development of the oral contraceptive steroids in the 1960s, various steroids and procedures have been used. Synthetic steroids are now used since their half-hves in the body are longer than the natural steroids. Combined oestrogen-progesterone contraception involves taking one piU each day which contains a synthetic progestogen plus an oestrogen. The pill is taken for 21 dyas, with a break for... [Pg.447]

Some antibiotics can reduce the efficacy of oral contraceptives. However, there is pharmacokinetic evidence that plasma concentrations of oral contraceptive steroids are unchanged by co-administration of ciprofloxacin (75). Furthermore, ciprofloxacin (500 mg bd) did not interfere with the ovarian suppression produced by the oral contraceptive Marvelon (30 micrograms of ethiny-lestradiol plus 150 micrograms of desogestrel) in 24 healthy women in a randomized, double-blind, placebo-controlled, crossover trial (76).
