Bicalutamide SUN

Bicalutamide SUN Uses, Dosage, Side Effects, Food Interaction and all others data.

Bicalutamide SUN 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 Bicalutamide SUN 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 Bicalutamide SUN 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 Bicalutamide SUN and an LHRH agonist, and who discontinue Bicalutamide SUN therapy due to progressive advanced prostate cancer, a reduction in Prostate Specific Antigen (PSA) and/or clinical improvement (antiandrogen withdrawal phenomenon) may be observed.

Bicalutamide SUN is an antineoplastic hormonal agent primarily used in the treatment of prostate cancer. Bicalutamide SUN is a pure, nonsteroidal anti-androgen with affinity for androgen receptors (but not for progestogen, estrogen, or glucocorticoid receptors). Consequently, Bicalutamide SUN 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.

Uses

Bicalutamide SUN 50 mg daily is used for use in combination therapy with a luteinizing hormone-releasing hormone (LHRH) analog for the treatment of Stage D2 metastatic carcinoma of the prostate.

Bicalutamide SUN 150 mg daily is not approved for use alone or with other treatments

Bicalutamide SUN is also used to associated treatment for these conditions: Stage D2 Prostatic carcinoma

How Bicalutamide SUN works

Bicalutamide SUN 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.

Dosage

Bicalutamide SUN dosage

The recommended dose for Bicalutamide SUN therapy in combination with an LHRH analog is one 50 mg tablet once daily (morning or evening), with or without food. It is recommended that Bicalutamide SUN be taken at the same time each day. Treatment with Bicalutamide SUN should be started at the same time as treatment with an LHRH analog.

Side Effects

Anaemia; angioedema, urticaria; decreased appetite, DM, wt gain, dehydration, gout; decreased libido, depression, anxiety, hypertonia, confusion, neuropathy, nervousness, dizziness, somnolence; hot flush; abdominal pain, constipation, nausea, dyspepsia, flatulence, anorexia, rectal haemorrhage, dry mouth, melaena; hepatotoxicity, jaundice, hypertransaminasaemia; alopecia, hirsutism, dry skin, pruritus/rash, photosensitivity; haematuria, dysuria, urinary retention, impaired urination, urinary frequency; gynaecomastia, breast tenderness, erectile dysfunction; asthenia, oedema, chest pain, neck pain, fever, sepsis, chills, neoplasm; cough, pharyngitis, bronchitis, pneumonia, rhinitis.

Precaution

Patient with decreased bone density, history of or risk factors for QT prolongation, diabetes, Moderate to severe hepatic and severe renal impairment (CrCl <30 mL/min).

Interaction

May induce torsade de pointes or QT prolongation if co-administered with class IA (e.g. quinidine) or class III (e.g. amiodarone) antiarrhythmic agents, methadone, antipsychotics, moxifloxacin. Enhanced anticoagulant effect of warfarin. Increased adverse effects when used with drugs that may inhibit oxidation (e.g. cimetidine, ketoconazole). May increase serum levels of ciclosporin and Ca channel blockers.

Food Interaction

  • Take at the same time every day.
  • Take with or without food. Food does not significantly affect absorption.

Bicalutamide SUN Disease Interaction

Moderate: hepatic dysfunction

Elimination Route

Bicalutamide SUN 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: Bicalutamide SUN 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 Bicalutamide SUN 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: Bicalutamide SUN has not been studied in women.

Acute Overdose

Long-term clinical trials have been conducted with dosages up to 200 mg of Bicalutamide SUN daily and these dosages have been well tolerated. A single dose of Bicalutamide SUN 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 Bicalutamide SUN, 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 Bicalutamide SUN 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.
