What LETROZOLE ACTAVIS
is used for
LETROZOLE ACTAVIS is used to
treat breast cancer in women who
are post-menopausal that is,
women who no longer have
periods, either naturally due to
their age or after surgery or
chemotherapy.
LETROZOLE ACTAVIS belongs to a
group of medicines called
aromatase inhibitors also called
‘antioestrogens’. These medicines
work by reducing the production of
oestrogen in your body.
Oestrogen stimulates the growth of
certain types of breast cancer.
These cancers are called
"oestrogen-dependent." Reducing
the production of oestrogen may
help to keep the cancer from
growing.
This may be the first time you are
taking an "antioestrogen" such as
letrozole or you may have taken
another "antioestrogen" such as
tamoxifen in the past.
Your doctor may have prescribed
LETROZOLE ACTAVIS for another
reason. Ask your doctor if you have
any questions about why
LETROZOLE ACTAVIS has been
prescribed for you.
LETROZOLE ACTAVIS is available
only with a doctor's prescription.
There is no evidence that
LETROZOLE ACTAVIS is addictive.

PHARMACOLOGY
PHARMACOTHERAPEUTIC GROUP
Non-steroidal aromatase inhibitor (inhibitor of oestrogen
biosynthesis); antineoplastic agent.
PHARMACODYNAMICS
The elimination of oestrogen-mediated stimulatory effects is a
prerequisite for tumour response
in cases where the growth of tumour tissue depends on the presence of
oestrogens. In
postmenopausal women, oestrogens are mainly derived from the action of
the aromatase enzyme,
which converts adrenal androgens - primarily androstenedione and
testosterone - to oestrone (E1)
and oestradiol (E2). The suppression of oestrogen biosynthesis in
peripheral tissues and the
cancer tissue itself can, therefore, be achieved by specifically
inhibiting the aromatase enzyme.
Letrozole is a non-steroidal aromatase inhibitor. Data suggest it
inhibits the aromatase enzyme
by competitively binding to the haem of the cytochrome P450 subunit of
the enzyme, resulting in
a reduction of oestrogen biosynthesis in all tissues.
In healthy postmenopausal women, single doses of 0.1, 0.5 and 2.5 mg
letrozole suppressed
serum oestrone and oestradiol by 75-78% and 78% from baseline,
respectively. Maximum
suppression was achieved in 48-78 h.
