`NOLVADEX®
`[nol ’va-ciexl
`tamoxifen citrate
`
`DESCRIPTION
`NOLVADEX® (tamoxifen citrate) Tablets, a nonsteroidal
`antiestrogen, are for oral administration. NOLVADEX Tab-
`lets are available as:
`10 mg Tablets. Each tablet contains 15.2 mg of tamoxifen
`citrate which is equivalent to 10 mg of tamoxifen.
`20 mg Tablets. Each tablet contains 30.4 mg of tamoxifen
`citrate which is equivalent to 20 mg of tamoxifen.
`Inactive Ingredients: carboxymethylcellulose calcium, mag-
`nesium stearate, mannitol and starch.
`Chemically, NOLVADEX is the trans-isomer of a triphenyl-
`ethylene derivative. The chemical name is (Z)2-[4-(1,2-di-
`phenyl-lebutenyl) phenoxyl-N, N-dimethylethanamine
`2~hydroxy-I,2,3-propanetricarboxylate (1:1). The structural
`and empirical formulas are:
`.
`
`(CH3)2N(CH2)2O<1
`
`:3: c\
`
`- csnao,
`
`(C3gH37NO_.3)
`Tamoxifen citrate has a molecular weight of 563.62, the
`pKa’ is 8.85, the equilibrium solubility in water at 37°C is
`0.5 mg/mL and in 0.02 N HCl at 37°C, it is 0.2 mg/mL.
`CLINICAL PHARMACOLOGY
`NOLVADEX is a nonsteroidal agent which has demon-
`strated potent antiestrogenic properties in animal test sys-
`tems. The antiestrogenic eifects may be related to its ability
`to compete with estrogen for binding sites in target tissues
`such as breast. Tamoxifen inhibits the induction of rat
`mammary carcinoma induced by dimethylbenzanthracene
`(DMBA) and causes the regression of already established
`DMBA-induced tumors. In this rat model, tamoxifen ap-
`pears to exert its antitumor effects by binding the estrogen
`receptors.
`In cytosols derived from human breast adenocarcinomas,
`tamoxifen competes with estradiol for estrogen receptor pro-
`tein.

`WARNINGS
`Visual disturbance including corneal changes, cataracts and
`retinopathy have been reported‘ in patients receiving
`NOLVADEX.
`As with other additive hormonal therapy {estrogens and an.
`dragons), hypercalcemia has been reported in some breast
`cancer patients with bone metastases within a few weeks of
`starting treatment with NOLVADEX. If hypercalcemia does
`occur, appropriate measures should be taken and, if severe,
`NOLVADEX should be discontinued.
`An increased incidence of endometrial cancer has been re-
`ported in association with NOLVADEX treatment. The un-
`derlying mechanism is unknown, but may be related to the
`estrogen-like effect of NOLVADEX. Any patients receiving
`or having previously received NOLVADEX, who report ab-
`normal vaginal bleeding should be promptly evaluated. Pa-
`tients receiving or having previously received NOLVADEX
`should have routine gynecological care and they should
`promptly inform their physician if they experience any ab-
`normal gynecological symptoms, eg, menstrual irregulari-
`ties, abnormal vaginal bleeding, changes in vaginal dis-
`charge, or pelvic pain or pressure.
`An increased incidence of eudometrial changes including
`hyperplasia and polyps have been reported in association
`with NOLVADEX treatment. The incidence and pattern of
`' this increase suggest that the underlying mechanism is re-
`lated to the estrogenic properties of NOLVADEX.
`In a large randomized trial
`in Sweden of adjuvant
`NOLVADEX 40 mg/day for 2-5 years, an increased inci-
`dence of uterine cancer was noted. Twenty-three of 1,372
`patients randomized to receive NOLVADEX versus 4 of
`1,357 patients randomized to the observation group devel-
`oped cancer of the uterus IRR = 5.6 (1.9-16.2), p<.0O1l. One
`of the patients with cancer of the uterus who was random- .
`ized to receive NOLVADEX never took the drug. After ap-
`proximately 6.8 years of follow-up in the NSABP B-14 trial,
`15 of 1,419 women randomized to receive NOLVADEX 20
`mg/day for 5 years developed uterine cancer and 2 of the
`1,424 women randomized to receive placebo, who subse-
`quently were treated with NOLVADEX, also developed uter-
`ine cancer. Most of the uterine cancers were diagnosed at an
`early stage, but deaths from uterine cancer have been re-
`ported.
`NOLVADEX has been associated with changes in liver en-
`zyme levels, and on rare occasions, a spectzum of more se-
`vere liver abnormalities including fatty liver, cholestasis,
`hepatitis and hepatic necrosis. A few of these serious cases
`included fatalities. In most reported cases the relationship
`to NOLVADEX is uncertain. However, some positive rechal-
`lenges and dechallenges have been reported.
`In the Swedish trial using adjuvant NOLVADEX 40 mg/day
`for 2-5 years, 3 cases of liver cancer have been reported in
`the NOLVADEX-treated group versus 1 case in the ob-
`servation group.
`In other clinical
`trials evaluating
`NOLVADEX, no other cases of liver cancer have been re-
`ported to date.
`Data from the NSABP B-14 study show no increase in other
`(non-uterine)
`cancers
`among
`patients
`receiving
`NOLVADEX. However, a number of second primary tumors,
`occurring at sites other than the endometrium, have been
`reported following the treatment of breast cancer with
`NOLVADEX in clinical trials. Whether an increased risk for
`other (non-uterine) cancers is associated with NOLVADEX
`is still uncertain and continues to be evaluated.
`Pregnancy Category D: NOLVADEX may cause fetal harm
`when administered to a pregnant woman. Women should be
`advised not to become pregnant while taking NOLVADEX
`and should use barrier or nonhormonal contraceptive meas-
`ures if sexually active. Effects on reproductive functions are
`expected from the antiestrogenic properties of the drug, In
`reproductive studies in rats at dose levels equal to or below
`the human dose, nonteratogenic developmental skeletal
`changes were seen and were found reversible. In addition,
`in fertility studies in rats and in teratology studies in rab-
`bits using doses at or below those used in humans, a lower
`incidence of embryo implantation and a higher incidence of
`fetal death or retarded in utero growth were observed, with
`slower learning behavior in some rat pups when compared
`to historical controls. Several pregnant marmosets were
`dosed during organogenesis or in the last halfof pregnancy
`No deformations were seen and, although the dose was high
`enough to terminate pregnancy in some animals, those that
`did maintain pregnancy showed no evidence of teratogenic
`malformations.
`In rodent models of fetal reproductive tract development,
`tamoxifen (at doses 0.3 to 2.4-fold the human maximum rec-
`ommended dose on a mg/rnz basis) caused changes in both
`sexes that are similar to those caused by estradiol, ethy-
`nylestradiol and diethylstilbestml. Although the clinical rel-
`evance of these changes is unknown, some of these changes,
`especially vaginal adeuosls, are similar to those seen in
`young women who were exposed to diethylstilbestrol in
`were and who have a 1 in 1000 risk of developing clear-cell
`adenocarcinoma of the vagina or cervix. ’Ib date, in utera
`exposure to tamoxifen has not been shown to cause vaginal
`adenosis, or clear-cell adenocarcinoma of the vagina or cer-

`vix, in young women. However, only a small number of
`young women have been exposed to tamoxifen in utero, and
`a smaller number have been followed long enough {to age
`l5~20) to determine whether vaginal or cervical neoplasia
`could occur as a result of this exposure.
`There are no adequate and well conlrolled trials of tamox-
`ifen in pregnant women. There have been a small number of
`reports ofvagioal bleeding, spontaneous abortions, birth do
`feots, and fetal deaths in pregnant women. If this drug is
`used during pregnancy, or the patient becomes pregnant
`while taking this drug, or within approximately two months
`after discontinuing therapy, the patient should be apprised
`of the potential risks to the fetus including the potential
`long term risk of a DES-like syndrome.
`PRECAUTIONS
`General: Decreases in platelet counts, usually to 50,000~
`100,000/mmg, infrequently lower, have been occasionally re-
`ported in patients taking NOLVADEX. for breast cancer. In
`patients. with significant thrombocytopenia, rare hemor-
`rhagic episodes have occurred, but it is uncertain if these
`episodes are due to NOLVADEX therapy Leukopenia has
`been observed, sometimes in association with anemia
`and/or thrombocytopenia. There have been rare reports of
`neutropenia and pancytopenia in patients receiving
`NOLVADEX; this can sometimes be severe.
