Bypro

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

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

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

Bypro 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.

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

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

How Bypro works

Bypro 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

Bypro dosage

The recommended dose for Bypro 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 Bypro be taken at the same time each day. Treatment with Bypro 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.

Bypro Disease Interaction

Moderate: hepatic dysfunction

Elimination Route

Bypro 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: Bypro 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 Bypro 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: Bypro has not been studied in women.

Acute Overdose

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