August 13, 2009 | Leave a Comment
Generic Name
Fenofibrate (fen-oe-Flli-brace) IM
Brand Names
Antara TriCor
Lipoten Triglide Lofibra
Type of Drug
Anti-hyperlipidemic (blood-fat reducer).
Prescribed For
High blood cholesterol and/or triglycerides; also prescribed for syndrome X, a condition which increases the risk of type 2 diabetes.
General Information
Fenofibrate works by interfering with the body’s ability to make triglyceride and by increasing its breakdown by enzymes in the body. It also reduces levels of uric acid, total cholesterol, low-density lipoprotein (LDL) cholesterol—the “bad” cholesterol—and other blood lipids. High-density lipoprotein (HDL) cholesterol—the “good” cholesterol—levels are increased. This drug should only be used in people with very high triglyceride levels who are at risk for pancreatitis (inflammation of the pancreas) and have not responded to other treatments, including statin drugs. Generic fenofibrate is not equivalent to the TriCor brand because of a new product formulation and should not be substituted for the brand unless your doctor approves of the switch.
Cautions and Warnings
Do not take fenofibrate if you are allergic or sensitive to any of its ingredients.
People taking fenofibrate and other triglyceride-lowering drugs are mate WOV to die from causes unrelated to triglyceride levels. Fenofibrate reduces the risk of a heart attack or other cardiac event in people with high triglyceride levels and low levels of HDL cholesterol, especially among people with diabetes. The evidence for this benefit is not as strong as it is for the statin drugs.
People taking fenofibrate and gemfibrozil may develop pancreatitis (inflammation of the pancreas).
People with liver or severe kidney disease should avoid fenofibrate. People with less severe kidney disease require reduced
dosage.
People taking fenofibrate are more likely to develop gallstones.
Fenofibrate can destroy muscle cells, leading to kidney failure, especially when combined with a statin cholesterol-lowering drug see “Drug Interactions”).
Possible Side Effects
• Most common: abnormal liver function, abdominal pain, and respiratory disorders.
♦ Common: rash, headache, upset stomach, pain, weakness, tiredness, and flu-like symptoms.
♦ Less common: joint pain, abnormal heart rhythms, reduced sex drive, dizziness, increased appetite, sleeplessness, tingling in the hands or feet, nausea, vomiting, diarrhea, abdominal pain, constipation, stomach noise or gas, frequent urination, vaginal irritation, runny nose, cough, sinus irritation, eye irritation, blurred vision, conjunctivitis (pinkeye). earache, and tiny particles inside the eye (”floaters”).
♦ Rare: allergic reactions including severe rash, itching, liver inflammation or enlargement, gallstones, gallbladder disease, muscle aches, and increased sensitivity to the sun. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Combining fenofibrate and a statin cholesterol-lowering drug (atorvastatin, cerivastatin, fluvastatin, lovastatin, pravastatin, or simvastatin) can lead to severe muscle pain, muscle cell destruction, and kidney failure. If you have extremely high blood-fat levels, the potential benefits of this combination may outweigh the risks. In people taking this combination, the health of muscles and kidneys must be monitored regularly via blood tests.
• Fenofibrate increases the effects of anticoagulant (blood-thinning) drugs. Your anticoagulant dosage may need an adjustment.
• Combining fenofibrate and cyclosporine can increase the risk of kidney toxicity. This combination should only be used if it is absolutely necessary and the lowest possible dosage is
taken.
• If you are taking cholestyramine or colestipol (both are used
to reduce blood-fat levels) as well as fenofibrate, take the
fenofibrate at least 1 hour before or 4-6 hours after these
drugs.
Food Interactions
All forms of fenofibrate, except TriCor, should be taken with food to get the best effect. TriCor may be taken without regard to food or meals.

Generic Name
Finasteride (fin-ASS-ter-ide) 19
Brand Names
Proscar Propecia
The information in this profile also applies to the following drug:
Generic Ingredient: Dutasteride Avodart
Type of Drug
Alpha-reductase inhibitor and androgen hormone inhibitor.
Prescribed for
Benign prostatic hyperplasia (BPH) and male-pattern baldness. May also play a role in preventing prostrate cancer.
General Information
Finasteride works by interfering with the action of the enzyme alphareductase, which converts testosterone into 5-dihydrotestosterone (DHT). By suppressing DHT levels, finasteride reduces the size of the prostate in most men who take the drug for BPH. You may need to take finasteride for 6-12 months before its effects can be
assessed.
Urine flow improves in about 60% of men taking finasteride for BPH and symptoms improve in about 30%. In one study, men experienced a significant regression in prostate size after 3 months, and the reduction was maintained through the 12-month study period: these men experienced a significant improvement in urine flow that could be maintained up to 36 months.
Studies of finasteride for hair loss on the top and back-middle of the scalp show new hair growth in 65-80% of men taking the drug continuously for 2 years. The drug must be taken for 3 months or more before it begins to have an effect and must be taken continuously to maintain hair growth. Once you stop taking this drug, any new hair you have grown is likely to fall out in the next 12 months. Between 14-17% of men taking the drug continued to lose hair throughout the study period.
Finasteride has been studied as therapy following radical prostatectomy surgery and in the prevention of first-stage prostate cancer, acne in women, and unusual hairiness.
Cautions and Warnings
Do not take finasteride if you are allergic or sensitive to any of its ingredients.
This drug should not be used in women or children. Pregnant women must not handle the tablets and capsules because of the risk to the fetus.
People who do not respond to finasteride may have a condition that causes BPH-like symptoms, such as prostate cancer, bladder or nerve disorders, or physical obstruction of the urinary tubes. Finasteride cannot be used to treat these conditions.
Because it is broken down in the liver, finasteride must be used with caution by people with liver disease.
Finasteride may mask symptoms of prostate cancer by causing a reduction in the level of prostate-specific antigen (PSA), an increasingly acknowledged indicator of prostate cancer.
Possible Side Effects
Side effects are generally mild and often subside with continued use of the drug.
Drug Interactions
• Finasteride may reduce the effectiveness of theophylline and aminophylline, although dosage adjustments usually are not required.
• Finasteride affects the PSA blood test used for prostate cancer screening. Be sure your doctor knows you are taking this drug if you have a PSA test done or are being tested for prostate cancer.
• Dustasteride blood levels may increase when mixed with ritonavir, ketoconazole, cimetidine, and ciprofloxacin, all of which are inhibitors of a liver enzyme called CYP3A4. Blood levels of dutasteride also increase with verapamil and diltiazem.
Food Interactions
You may take finasteride with food if it upsets your stomach.
Usual Dose
Outasteride
Adult: 0.5 mg (1 capsule) once a day. Child: not recommended.
Finasteride
Adult: BPH-5 mg once a day. Male-pattern baldness-1 mg once a day.
Child: not recommended.
Women should not take finasteride. Overdosage
S%’& Ptecls are unlikely. Doses of dutasteride as high as 400 mg a day have been taken with no adverse side effects. Call your local poison control center or a hospital emergency room for more information. If you seek treatment, ALWAYS bring the prescription bottle or container.
Possible Side Effects (continued)
v Common: impotence, loss of sex semen, breast tenderness an
• and drug sensitivity reaction
• rash.
x drive, decreased amount nd enlargement, testicular ions including lip swelling Special Information
Women who are or might be pregnant should not handle crushed finasteride tablets because small amounts of the drug may be absorbed into the blood, possibly affecting the fetus.
If your sexual partner is or might be pregnant and you start taking finasteride, you must wear a condom during sex to avoid directly exposing her to finasteride in the semen.
Semen volume may decrease while on finasteride. Impotence or reduced sex drive is also a risk.
If you forget a dose, take it as soon as you remember. If it is almost time for your next dose, skip the one you forgot and continue with your regular schedule. Do not take a double dose. Call your doctor if you miss a dose for 2 or more days.
Special Populations
Pregnancy/Breast-feeding: This drug is not intended for women. Finasteride will harm the fetus if taken during pregnancy. It is not known if finasteride passes into breast milk.
Seniors: Seniors with liver disease should use this drug with caution.

Efalizumab (ef-ah-LIZ-u-mab)
Brand Name Raptiva
Type of Drug
Immune system suppressant.
Prescribed For
Chronic to severe plaque psoriasis.
General Information
Efalizumab is a manmade antibody that works by binding to specific areas of certain white blood cells called leukocytes. This prevents the leukocytes from interacting with other cells and interrupts inflammation that is involved in the development of patches of psoriatic skin. The molecule that efaluzimab interacts with is found on many other key cells found in the immune system, and this is the source of many of the drug’s more serious side effects.
Cautions and Warnings
Do not use this drug if you are allergic or sensitive to any of its ingredients.
People taking efalizumab are at a greater risk of infection because it suppresses the immune system. Contact your doctor if you develop any kind of infection, including a common cold. Serious infections may require hospitalization.
The chances of malignancy may be increased by efalizumab because it suppresses the immune system. People with any type of cancer should not use this drug.
Efalizumab may lead to bleeding because it can cause a drastic reduction in blood-platelet counts. People with a history of low blood-platelet counts should be extremely cautious about using efalizumab.
Psoriasis can get worse or recur during or after efalizumab treatment in a small number of people. Call your doctor immediately if your condition worsens while you are taking efalizumab.
Possible Side Effects
Headache, fever, nausea, and vomiting are common alter taking the very first dose of elaki7umab. A “conditioning” dose of about 0.3 mg per lb. of body weight is often given to minimize these reactions.
V Most common: headache, infections, chills, nausea, and pain.
V Common: muscle aches, flu-like symptoms, itching, and fever.
Possible Side Effects (continued)
✓ Less common: back pain, arthritis, lung inflammation, and
acne.
♦ Rare: psoriasis, arthritis, joint pain, malignancy, low blood-platelet count, and drug allergy or sensitivity. Other rare side effects can occur in almost any part of the body. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Efalizumab is an immune system suppressant and should not be combined with other immune suppressant drugs because of the increased risk of infection and malignancy.
• Combining vaccines (live and acellular) with efalizumab may exaggerate the body’s response to the vaccine and increase the risk of developing the disease against which the vaccination is being administered. People taking etalizurnab should not receive vaccines.
Food Interactions None known.
Usual Dose
Adult: 0.3 mg per lb. of body weight to start. Then about 0.5 mg per lb. of body weight once a week on the same day. The maximum dose is 200 mg by subcutaneous injection. Mix your dose immediately before it is to be injected and throw away any unused medicine.
Child: not recommended.
Overdosage
Doses up to 4 times the recommended dose have been taken for 10 weeks without additional side effects. However, overdose victims should be taken to a hospital emergency room for observation. ALWAYS bring the prescription bottle or container.
Special information
See your doctor regularly while you are taking efaluzima6. Regular blood tests are required to make sure your blood platelets are not unusually low.
Tell your doctor if you gain or lose weight, since doses of efaluzimab are based on how much you weigh.Tell your doctor about all medicines you are taking including other medicines for psoriasis, non-prescription drugs, vitamins,
and herbal supplements.
Store unused medicine in the refrigerator. Throw away medicine that has been mixed but not used.
Call your doctor immediately if you develop bleeding gums, black-and-blue marks, any kind of infection, begin to bruise easily, or if you are told by another doctor that you have any kind of cancer.
This drug is given by injection under the skin. For more information on how to properly administer this drug, see page 1242.
Special Populations
Pregnancy/Breast-feeding: It is not known how efaluzimab will affect a growing fetus. Animal studies using doses equal to 30 times the human dose showed no adverse effects. While animal studies of efaluzimab reveal no damage to the fetus, this drug should be used only during pregnancy after carefully weighing its potential benefits against its risks.
It is not known if efaluzimab passes into breast milk, although it might affect the nursing infant’s developing immune system. Nursing mothers who must take this drug should use infant formula.
Seniors: Seniors should be cautious about using efaluzimab because of the increased risk of infection.

Generic Name
Enalapril (uh-NAL-uh-pril)
Brand Name
Vasotec
Combination Product
Ggner;c Ingredients: Enalapril + Hydrochlorothiazide RE Vaseretic
Type of Drug
Angiotensi n -converting enzyme (ACE) inhibitor.
Prescribed For
Hypertension (high blood pressure), heart failure, diabetic kidney disease, and heart attack treatment when the function of the left ventricle has been affected. Also prescribed for kidney failure, kidney hypertension, managing people with a high risk of heart disease, chronic kidney disease, and preventing a second stroke.
General Information
Enalapril maleate and other ACE inhibitors work by preventing the conversion of a hormone called angiotensin I to another hormone called angiotensin II, a potent blood-vessel constrictor. Preventing this conversion relaxes blood vessels, thus reducing blood pressure and relieving symptoms of heart failure. Enalapril also affects the production of other hormones and enzymes that participate in the regulation of blood-vessel dilation. Enalapril begins working about 1 hour after you take it and continues to work for 24 hours.
Cautions and Warnings
Do not take enalapril if you are allergic or sensitive to any of its ingredients. Severe sensitivity reactions can occur in hemodialysis patients taking enalapril or those undergoing venom immunization.
Swelling of the face, extremities, or throat has been known to occur with enalapril, which can be dangerous (see “Special Information”).
Enalapril occasionally causes very low blood pressure.
Enalapril may affect your kidney function, especially if you have congestive heart failure. Your doctor should check your urine for protein content during the first few months of treatment. Dosage adjustment of enalapril is necessary if you have reduced kidney function.
Enalapril can affect white-blood-cell counts, possibly increasing your susceptibility to infection. Your doctor should monitor your blood counts periodically.
Enalapril may cause serious Injury or death to the fetus if taken duriRcA pregnancy. Pregnant women should not take enalapril.
ACE inhibitors may be less effective in some black patients with high blood pressure, especially when dietary salt intake is high. Nevertheless, they should still be considered useful blood pressure treatments. Swelling beneath the skin to form welts is more common among black patients.
Possible Side Effects
♦ Most common-. dizziness, fatigue, headache, and chronic cough. The cough usually goes away a few days after you stop taking the medication.
♦ Less common: chest tightness or pain, dizziness when rising from a sitting or lying position, fainting, abdominal pain, nausea, vomiting, diarrhea, bronchitis, urinary tract infection, breathing difficulties, weakness, and rash.
♦ Rare: Rare side effects can occur in almost any part of the body. Contact your doctor if you experience any side effect not listed above.
For additional information about enalapril + felodipine, see Felodipine, page 471.
Drug Interactions
• The blood-pressure-lowering effect of enalapril is additive with diuretic drugs and beta blockers. Any other drug that causes a rapid drop in blood pressure should be used with caution if you are taking enalapril.
• Enalapril may increase the effects of lithium; this combination should be used with caution.
• Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) reduce the blood-pressure-lowering effects of enalapril and other ACE inhibitors. The combination may cause reductions in kidney function.
• Enalapril may increase blood-potassium levels, especially when taken with dyazide or other potassium-sparing diuretics.
• Antacids and enalapril should be taken at least 2 hours apart.
• Capsaicin may trigger or aggravate the cough associated with enalapril therapy.
• Indomethacin may reduce the blood-pressure-lowering effects of enalapril.
• Phenothiazine sedatives and antiemetics may increase the ef - feZIS of enalapril.
• Rifampin may reduce the effects of enalapril.
• The combination of allopurinol and enalapril increases the chance of side effects. Avoid this combination.
• Enalapril affects blood levels of digoxin. More digoxin in the blood increases the chance of digoxin-related side effects, while less digoxin in the blood can compromise its effectiveness.

Generic Name
Entacapone (in-TACK-a-pohn)
Brand Name Comtan
Type of Drug Antiparkinsonian.
Prescribed For
Parkinson’s disease patients for whom levodopa + carbidopa loses its effectiveness between doses.
General Information
Entacapone is always used in combination with levodopa + carbidopa. Some patients experience signs and symptoms of an end-of-dose “wearing-off” effect with these drugs. Entacapone enhances the effect of levodopa + carbidopa by reversing the action of an enzyme known as catechol-O-methyltransferase (COMT), which is primarily responsible for breaking down levodopa in the body.
Cautions and Warnings
Do not take entacapone If yOU are allergic or sensitive to any of At *Ingredients.
Do not take entacapone with phenelzine or tranyleypromine, as a very serious reaction may occur.
People with liver disease should use entacapone with caution as they may accumulate twice as much of this drug in their blood as people with normal liver function.
Entacapone has been rarely associated with the formation of fibrous tissues in unusual places such as the urinary tract and lungs. It has also caused fluid in the lungs.
Entacapone may cause kidney toxicity.
Entacapone may increase the risk of dizziness or fainting when rising from a sitting or lying down position.
Hallucinations have been reported with other Parkinson’s disease drugs.
Possible Side Effects
♦ Most common: difficulty performing voluntary muscle functions, excessive muscle activity, nausea, urine discoloration, and diarrhea.
♦ Common: reduced muscle activity, dizziness, fatigue, constipation, and abdominal pain.
✓ Less common: low blood pressure and fainting when rising from a sitting or lying position, hallucinations, anxiety, agitation, gastritis or other stomach disorders, dry mouth, vomiting, increased sweating, back pain, taste changes, shortness of breath, easy bruising, weakness, and bacterial infection.
♦ Rare: muscle damage or death, high fever, and confusion. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Do not mix entacapone with the monoamine oxidase inhibitor (MAGI) antidepressants phenelzine or tranylcypromine. Entacapone may be taken with the MAGI selegiline.
• Other drugs broken down by COMT will also be affected by entacapone. Isoproterenol, epinephrine, ephedrine, norepinephrine, isoetharine, and others will interact with entacapone, even when taken by inhalation. The result may be increased heart rate, wybylh m ias, and excessive changes in Uwd pressure.
• Cholestyramine, probenecid, erythromycin, rifampin, ampicillin, and chloramphenicol may interfere with the elimination of entacapone from the body.
• Entacapone may enhance the effects of sedatives and other nervous system depressants.
Food Interactions
This drug may be taken with or without food.
Usual Dose
Adult: 200 mg with each levodopa + carbidopa dose, up to
1600 mg a day.
Child: not recommended.
Overdosage
Theoretically, a massive entacapone overdose could prove lethal by completely inhibiting COMT throughout the body. There have been no reports of significant entacapone overdose. Doses up to 800 mg have been taken and side effects were mainly abdominal pain and loose stools. Other effects that might be expected include difficulty breathing, loss of muscle coordination, reduced level of activity, and convulsions. Overdose victims should be taken to a hospital emergency room as soon as possible. ALWAYS bring the prescription bottle or container.
Special Information
Always take your entacapone dose together with your levodopa + carbidopa dose. If you forget a dose, take it as soon as you remember. If it is within 2 hours of your next dose, skip the dose you forgot and continue with your regular schedule.
This drug can cause dizziness, nausea, sweating, or fainting when rising quickly from a sitting or lying position, especially at the beginning of treatment.
Increased body movements and twitching, twisting, or uncontrolled tongue, lip, face, arm, or leg movement may occur. If this happens, your doctor may need to adjust your dose of levodopa + carbidopa.
Exercise caution when performing tasks, such as driving, that require coordination and concentration until your body has become accustomed to the effects of entacapone.
Gradually reducing the dose of entacapone decreases some drug side effects.
Rapid withdrawal can cause high fever, sweating, unstable blood pressure, stupor, and muscular rigidity. Patients who stop using entacapone should be monitored.
Entacapone can cause your urine to turn a brownish-orange color. This change is harmless.
