Bicalutamid-Teva
Bicalutamid-Teva Uses, Dosage, Side Effects, Food Interaction and all others data.
Bicalutamid-Teva is a non-steroidal androgen receptor inhibitor. It competitively inhibits the action of androgens by binding to cytosol androgen receptors in the target tissue. Prostatic carcinoma is known to be androgen sensitive and responds to treatment that counteracts the effect of androgen and/or removes the source of androgen.
When Bicalutamid-Teva is combined with luteinizing hormone releasing hormone (LHRH) analog therapy, the suppression of serum testosterone induced by the LHRH analog is not affected. However, in clinical trials with Bicalutamid-Teva as a single agent for prostate cancer, rises in serum testosterone and estradiol have been noted.
In a subset of patients who have been treated with Bicalutamid-Teva and an LHRH agonist, and who discontinue Bicalutamid-Teva therapy due to progressive advanced prostate cancer, a reduction in Prostate Specific Antigen (PSA) and/or clinical improvement (antiandrogen withdrawal phenomenon) may be observed.
Bicalutamid-Teva is an antineoplastic hormonal agent primarily used in the treatment of prostate cancer. Bicalutamid-Teva is a pure, nonsteroidal anti-androgen with affinity for androgen receptors (but not for progestogen, estrogen, or glucocorticoid receptors). Consequently, Bicalutamid-Teva blocks the action of androgens of adrenal and testicular origin which stimulate the growth of normal and malignant prostatic tissue. Prostate cancer is mostly androgen-dependent and can be treated with surgical or chemical castration. To date, antiandrogen monotherapy has not consistently been shown to be equivalent to castration.

How Bicalutamid-Teva works
Bicalutamid-Teva competes with androgen for the binding of androgen receptors, consequently blocking the action of androgens of adrenal and testicular origin which stimulate the growth of normal and malignant prostatic tissue.

Bicalutamid-Teva Disease Interaction
Elimination Route
Bicalutamid-Teva is well-absorbed following oral administration, although the absolute bioavailability is unknown.
Half Life
5.9 days
Clearance
- Apparent oral cl=0.32 L/h [Normal Males]
Pregnancy & Breastfeeding use
Pregnancy category X. Studies in animals or human beings have demonstrated foetal abnormalities or there is evidence of foetal risk based on human experience or both, and the risk of the use of the drug in pregnant women clearly outweighs any possible benefit. The drug is contraindicated in women who are or may become pregnant.
Nursing Mothers: Bicalutamid-Teva is not indicated for use in women.
Contraindication
Females, children, Pregnancy and lactation. Concomitant use of terfenadine, astemizole or cisapride.
Special Warning
Renal Impairment: No dosage adjustment is necessary for patients with renal impairment.
Hepatic Impairment: No dosage adjustment is necessary for patients with mild to moderate hepatic impairment. In patients with severe liver impairment (n=4), although there was a 76% increase in the half-life (5.9 and 10.4 days for normal and impaired patients, respectively) of the active enantiomer of bicalutamide no dosage adjustment is necessary.
Pediatric Use: The safety and effectiveness of Bicalutamid-Teva in pediatric patients have not been established.
Geriatric Use: In two studies in patients given 50 or 150 mg daily, no significant relationship between age and steady-state levels of total bicalutamide or the active R-enantiomer has been shown.
Women: Bicalutamid-Teva has not been studied in women.
Acute Overdose
Long-term clinical trials have been conducted with dosages up to 200 mg of Bicalutamid-Teva daily and these dosages have been well tolerated. A single dose of Bicalutamid-Teva that results in symptoms of an overdose considered to be life threatening has not been established. There is no specific antidote; treatment of an overdose should be symptomatic.
In the management of an overdose with Bicalutamid-Teva, vomiting may be induced if the patient is alert. It should be remembered that, in this patient population, multiple drugs may have been taken. Dialysis is not likely to be helpful since Bicalutamid-Teva is highly protein bound and is extensively metabolized. General supportive care, including frequent monitoring of vital signs and close observation of the patient, is indicated.
Storage Condition
Store at controlled room temperature, 20° to 25° C.
