RAPACT 5MG

RAPACT DESCRIPTION

Rapact 5mg containing an active ingredient known as Everolimus which is intercedes with cancer cell growth and slows down its process.

Rapact 5mg tablets are not used as curable medicine, which is used to slow their spreading in to the body.

RAPACT 5MG PRESCRIBING INFORMATION

Rapact 5mg tablets are mainly indicated in;

Renal carcinoma

Breast carcinoma

Brain carcinoma

Everolimus is also used in various advanced stage cancer in stomach, intestines or pancreas.

RAPACT 5MG MECHANISM

Everolimus is an mTOR prohibitor, binds at high compatibility to FK506 binding protein 12, through producing drug complex that prohibits the effective of mTOR.

This prohibition decreases the activity of effectors downstream, which may causes blockage of cell progression from G1 into S phase, subsequently causes cell growth arrest and apoptosis

Absorption

The peak plasma concentration time of Everolimus reaches within 1 to 2 hours.

The effect of food with Rapact is given below; With heavy meal: Reduction of systemic exposure to Rapact, and the peak blood plasma concentration by 54%.

Distribution

The blood plasma ratio of Rapact with the range of 5 to 5000ng/ml is 17% to 73%. Rapact human plasma protein bound with the range of 74%.

Metabolism

The metabolism of Everolimus is occurred in liver, which is a substrate of CYP3A4.

The metabolites of Everolimus;

 Three monohydroxylated metabolite,

Two hydrolytic rings opened products, &

 Phosphatidylcholine conjugate of Everolimus.

Excretion

The terminal half-life period of Everolimus is relatively 30 hours

The major route of elimination;

5% in urine; the parent compound has been detected in urine or feces.

DOSAGE REGIMEN AND ADMINISTRATION OF RAPACT

In breast cancer, renal cell cancer, pancreatic cancer, Neuro endocrine cancer:

The recommended dosage is 10mg should be taken as a single dose.

In Brain or intracranial cancer

The recommended dosage of Rapact is 4.5mg/m² orally as a single dose.

In pediatric

The usual pediatric dosage of Rapact in brain or intracranial tumor is 4.5mg/m² should be taken orally as a single dose. 

Rapact tablets should be administered with or without food.

OVER DOSAGE;

The over dosage of Everolimus is rarely occur, in case of over dosage patient must be provide with supportive measures. The acute toxicity of Everolimus over dosage should be monitored.

RAPACT 5MG CAUSED SIDE EFFECTS

• Hypersensitivity reactions
• Lymphomas & other malignancy
• Serious infections
• Kidney graft thrombosis
• Hepatic artery thrombosis
• Nephrotoxicity
• Hyperlipemia
• Angioedema
• Interstitial lung disease
• Thrombocytopenia
• Male infertility
• Proteinuria
• New commencement of diabetes

DRUG – DRUG INTERACTION

• Rapact 5mg is metabolized hepatically, a substrate of CYP3A4.
• Rapact 5mg combined with strong inhibitor of CYP3A4, or P-gp, leads to cause decreasing the efflux of Everolimus and increase the plasma concentration of Everolimus.
• Rapact 5mg with strong CYP3A4 inducers, causes increasing the exposure of Everolimus.
• Co administration of Rapact 5mg with cyclosporine causes increasing the AUC level of Everolimus frequently.
• Rapact 5mg tablet is combined with ketaconazole or other CYP3A4 inhibitors causes increasing the plasma concentration and AUC of Everolimus.
• Concomitant of Rapact 5mg with erythromycin causes increasing in AUC of Everolimus.
• Co administration of Rapact 5mg with verapamil leads to increasing the plasma concentration of Everolimus.
• Co administration of Rapact 5mg with Atorvastatin or pravastatin causes rhabdomyolysis, due to increasing concentration of lipid lowering agents.

CONTRAINDICATION

Some anaphylactic reaction occurs, if patients are contraindicated to the components present in the Rapact 5mg tablets.

SAFETY MEASURES

Lymphomas

Increased exposure of skin cancers, patient may protect from UV light

Serious infections

Patients receiving Rapact 5mg have high risk of acquiring various infections related to bacteria, virus, and fungi.

Anti-microbial agents are preferred for the suspected patients.

Hepatic artery thrombosis

In liver transplant patients, Rapact 5mg therapy should not be recommended.

Nephrotoxicity

Renal function should be monitored frequently; caution should be taken while using Rapact 5mg in renal impaired patients.

Angioedema

This may have occurred in the patients receiving concomitantly Rapact 5mg with Angiotensin converting enzyme agents

Hyperlipidemia

Patient getting Rapact 5mg with lipid lowering drugs causes increasing in plasma concentration of these drugs causes hyperlipidemia

Interstitial lung disease: Occurred in Rapact 5mgtherapy

Thrombocytopenia: Using Rapact 5mg with cyclosporine causes thrombocytopenia

Outbreak of diabetes: Blood glucose level should be monitored

Embryo fetal toxicity: Causes fetal damage using Rapact 5mg in pregnancy condition

Immunization: Using live vaccines in Rapact 5mg therapy

Hereditary disorders: In the conditions like galactose intolerance, glucose-galactose malabsorption, Rapact 5mg should not be used may results in diarrhea & malabsorption.

Interact with grape juice: Causes increasing blood levels of Everolimus; avoid these concomitants.

PREGNANCY AND LACTATION

Pregnancy category of Everolimus C

Rapact 5mg is used only by the patients after knowing the benefits to the mother outweighs the risk to fetus.

Breast feeding should not be suggested

On the other hand, the missed dose should be avoiding and follow the regular dosing schedule.

OVER DOSAGE

The over dosage of Everolimus is rarely occur, in case of over dosage patient must be provide with supportive measures. The acute toxicity of Everolimus over dosage should be monitored.
