CLINICAL PHARMACOLOGY
Combination oral contraceptives act by suppression of gonadotropins.
Although the primary mechanism
of this action is inhibition of ovulation, other alterations include
changes in the cervical mucus (which
increase the difficulty of sperm entry into the uterus) and the
endometrium (which reduce the likelihood
of implantation).
INDICATIONS AND USAGE
Oral contraceptives are indicated for the prevention of pregnancy in
women who elect to use this
product as a method of contraception.
Oral contraceptives are highly effective. Table I lists the typical
accidental pregnancy rates for users
of combination oral contraceptives and other methods of contraception.
The efficacy of these
contraceptive methods, except sterilization and the IUD, depends upon
the reliability with which they
are used. Correct and consistent use of methods can result in lower
failure rates.
