Warnings
Contraindications
Severe hepatic Impairment
Cautions
Congenital long QT syndrome, drugs/conditions that prolong QT interval; correct hypokalemia or hypomagnesemia before commencing treatment
Thrombocytopenia and anemia may require dose modification or discontinuation; monitor blood counts every 2 weeks during first 2 months of therapy and monthly thereafter
Severe thrombocytopenia with gastrointestinal bleeding reported with other HDAC inhibitors (e.g., valproic acid); monitor platelet counts more frequently
Monitor for pertinent signs and symptoms of pulmonary embolism and deep vein thrombosis
Potential for hyperglycemia; caution in diabetes; monitor blood glucose every 2 weeks during first 2 months of therapy and monthly thereafter
Dose related anemia and thrombocytopenia may occur; modify dose or discontinue if reduction in platelets or Hgb
Concomitant valproic acid
May cause dizziness or fatigue
Concomitant coumarin-derived anticoagulants
Hepatic/renal impairment
Nausea, vomiting and diarrhea; patients may require antiemetics, antidiarrheals, and fluid and electrolyte replacement to prevent dehydration
Avoid pregnancy
Drink at least 2 L of fluids daily
Measure and correct abnormal electrolytes, creatinine, magnesium and calcium at baseline; monitor every 2 weeks during first 2 months of therapy and at least monthly during treatment
Pregnancy & Lactation
Pregnancy
Based on mechanism of action and findings from animal studies, therapy can cause fetal harm when administered to a pregnant woman
There are insufficient data in pregnant women to inform a drug-associated risk of major birth defects and miscarriage
Advise pregnant women of potential risk to fetus
Animal data
- In animal reproduction studies, administration of drug to pregnant rats and rabbits during period of organogenesis caused adverse developmental outcomes at maternal exposures approximately 0.5 times the human exposure based on AUC0-24 hours
Reproductive potential
- Can cause fetal harm when administered to a pregnant woman
Pregnancy testing
- Perform pregnancy testing in females of reproductive potential within 7 days prior to initiating therapy
Contraception
- Females: Advise patients of reproductive potential to use effective contraception during treatment and for at least 6 months after the last dose
- Males: Advise males with female partners of reproductive potential to use effective contraception and to avoid fathering a child during treatment with ZOLINZA and for at least 3 months after the last dose
Infertility
- Based on findings in animals, therapy has the potential to affect female fertility
Lactation
There are no data on presence of drug or its metabolites in human milk, effects on a breastfed child, or on milk production; because many drugs are excreted in human milk and because of potential for serious adverse drug reactions in a nursing child, advise lactating women not to breastfeed during treatment and for at least 1 week after last dose
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Histone deacetylase inhibitor for enzymes HDAC1, HDAC2, HDAC3, and HDAC6, which in turn alters chromatin structure and transcription factor activation; as a result, cell growth is terminated and apoptosis occurs

Peak plasma concentration (400 mg dose): 1.2±0.62 umol/L
Fasted state has quicker peak time, but lower AUC and peak concentration
Taken with a high fat meal increases extent of absorption by 33%
Bioavailability: 43%

VORINOSTAT - ORAL
(vor-IN-oh-stat)
COMMON BRAND NAME(S): Zolinza
USES: Vorinostat is used to treat a certain type of cancer (CTCL-cutaneous T-cell lymphoma). It works by slowing or stopping the growth of cancer cells.
HOW TO USE: Read the Patient Information Leaflet if available from your pharmacist before you start taking vorinostat and each time you get a refill. If you have any questions regarding the information, ask your doctor or pharmacist.Take this medication by mouth with food as directed by your doctor, usually once daily. Swallow the capsules whole. Do not crush, chew, or open the capsules. To prevent dehydration while taking this medication, drink at least 8 glasses of water (8 ounces/240 milliliters each) throughout the day unless your doctor directs you otherwise.Do not use capsules that are opened or crushed. If your skin or eyes come in contact with the powder inside the capsule, wash the area well with plenty of water and call your doctor.The dosage is based on your medical condition and response to treatment. Do not increase your dose or take this medication more often than prescribed. Your condition will not improve any faster, and the risk of serious side effects may be increased.Since this drug can be absorbed through the skin and lungs, women who are pregnant or who may become pregnant should not handle this medication or breathe the dust from the capsules.Tell your doctor if your condition does not improve or if it worsens.
SIDE EFFECTS: Tiredness, loss of appetite, weight loss, dizziness, dry mouth, change in the sense of taste, hair loss, headache, or cough may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.Nausea, vomiting, and diarrhea can also occur and may be severe. Tell your doctor right away if these effects occur. In some cases, your doctor may prescribe medication to prevent or relieve them. Eating several small meals, not eating before treatment, or limiting activity may help to lessen the nausea and vomiting.People using this medication may have serious side effects. However, you have been prescribed this drug because your doctor has judged that the benefit to you is greater than the risk of side effects. Careful monitoring by your doctor may decrease your risk.Vomiting/diarrhea that doesn't stop may result in dehydration. Contact your doctor promptly if you notice any symptoms of dehydration, such as unusual decreased urination, unusual dry mouth/thirst, fast heartbeat, or dizziness/lightheadedness.This medication may rarely make your blood sugar rise, which can cause or worsen diabetes. Tell your doctor right away if you have symptoms of high blood sugar such as increased thirst/urination. If you already have diabetes, check your blood sugar regularly as directed and share the results with your doctor. Your doctor may need to adjust your diabetes medication, exercise program, or diet.This medication decreases bone marrow function, an effect that may lead to a low number of blood cells such as red cells, white cells, and platelets.
