Bicalutamida Tiefenbacher
Bicalutamida Tiefenbacher Uses, Dosage, Side Effects, Food Interaction and all others data.
Bicalutamida Tiefenbacher 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 Bicalutamida Tiefenbacher 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 Bicalutamida Tiefenbacher 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 Bicalutamida Tiefenbacher and an LHRH agonist, and who discontinue Bicalutamida Tiefenbacher therapy due to progressive advanced prostate cancer, a reduction in Prostate Specific Antigen (PSA) and/or clinical improvement (antiandrogen withdrawal phenomenon) may be observed.
Bicalutamida Tiefenbacher is an antineoplastic hormonal agent primarily used in the treatment of prostate cancer. Bicalutamida Tiefenbacher is a pure, nonsteroidal anti-androgen with affinity for androgen receptors (but not for progestogen, estrogen, or glucocorticoid receptors). Consequently, Bicalutamida Tiefenbacher 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.

Elimination Route
Bicalutamida Tiefenbacher 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: Bicalutamida Tiefenbacher 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 Bicalutamida Tiefenbacher 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: Bicalutamida Tiefenbacher has not been studied in women.
Acute Overdose
Long-term clinical trials have been conducted with dosages up to 200 mg of Bicalutamida Tiefenbacher daily and these dosages have been well tolerated. A single dose of Bicalutamida Tiefenbacher 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 Bicalutamida Tiefenbacher, 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 Bicalutamida Tiefenbacher 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.
