Aliskiren
July 16, 2009 | Leave a Comment
Generic Name
Aliskiren (ah-LISS-kih-ren)
Brand Name Tekturna
Combination Product
Generic Ingredients: Aliskiren + Hydrochlorothiazide Tekturna HCT
Type of Drug
Direct renin inhibitor. Prescribed For
High blood pressure.
General Information
Renin is produced by the kidney in response to a reduction in blood volume and the amount of blood passing through the kidney. Once in the blood, renin reacts with other hormones to forma very powerful blood vessel constrictor called angiotensin E that directly raises blood pressure. Renin also works with a hormore called aldosterone to raise blood pressure and it prevents sodium from being eliminated from the body. This increases the amount of water in the system, raising blood volume and increasing blood pressure. Aliskiren inhibits renin and all of its actions, thereby !owering blood pressure. The blood pressure lowering is usually seen with 2 weeks of starting on treatment. When aliskiren treatment is stopped, blood pressure gradually rises to pre-treatment levels. Only about 21/2% of any dose is absorbed into the blood and it takes about a week to reach a steady level in the blood. Most of the drug that is absorbed is broken down in the liver. The rest passes out of the body unchanged in the urine. Aliskiren may be used alone or with other hypertensives, however its use with maximum doses of an ACE inhibitor has not been adequately studied.
Cautions and Warnings
Do not take aliskiren if you are allergic or sensitive to any of its ingredients.
Angioedema swelling of the face, hands or feet, tongue, or throat can occur at any time during aliskiren treatment. If this happens, stop taking the medicine and go to your doctor’s office or a hospital emergency room for treatment. This reaction can interfere with your breathing.
The safety of aliskiren in people with moderate to severe kidney disease is not known.
The combination of aliskiren and an ACE inhibitor can lead to high blood levels of potassium.
Aliskiren may be less effective in some black patients with high blood pressure, especially when dietary salt intake is high. Nevertheless, it should still be considered a useful blood pressure treatment.
Possible Side Effects
✓ Common: nausea, dizziness, and sleeplessness.
✓ Less common: diarrhea, abdominal pain, upset stomach, GERD, cough, rash high blood uric acid levels, gout, kidney stones, headache, nose and throat irritation, fatigue, upper respiratory infection, and back pain.
✓ Rare: difficulty breathing; swelling of the hands, face, eyes, or whole body; and seizures. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Mixing aliskiren with irbesartan can reduce the amount of aliskiren into the blood by 50%. This may reduce the effectiveness of aliskiren.
• Aliskiren has been studied together with both hydrochlorothiazide and valsartan and can be combined with them in blood pressure management. It has been used with amlodipine but may not be better than high dose amlodipine alone.
• Aliskiren’s interaction with ACE inhibitors is not yet fully known.
• Atorvastatin and ketoconazole slow the breakdown of aliskiren, resulting in an increase of aliskiren blood levels by 50% or more. Dosage adjustment may be necessary.
Aliskiren can reduce blood levels of the diuretic furosemide, reducing the diuretic’s effect.
Food Interactions
Aliskiren can be taken without regard to food or meals. Avoid taking it with high fat meals because they can drastically reduce the amount of aliskiren absorbed into the blood.
Usual Dose
Adult (age 18 and over)
Tekturna: 50-300 mg at the same time every day. Tekturna HCT. 1 tablet a day.
Child: not recommended. Overdosage
The most likely symptom of overdose is low blood pressure (symptoms include dizziness and fainting). If you think you have taken an overdose, call your doctor or go to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Call your doctor at once if you develop swelling of the face, eyes, lips, tongue, or throat; difficulty swallowing or breathing; hoarseness; or other signs of a drug reaction or allergy.
If you forget a dose, take it as soon as you remember. If you do not remember until it is almost time for your next dose, skip the dose you forgot and continue with your regular schedule. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: Aliskiren can injure or kill a developing fetus. Pregnant women should not take aliskiren. Women who suspect they are pregnant must call their doctor at once and stop taking aliskiren when pregnancy is confirmed. In those rare cases where aliskiren is considered life-saving for the mother and there is no substitute for aliskiren, your doctor may advise that you continue on the medicine and then check your baby’s development with periodic ultrasound examinations.
It is not known if this drug passes into breast milk. Nursing mothers should use infant formula.
Seniors: Seniors may have higher blood levels of aliskiren and be more susceptible to drug side effects, but starting dose adjustment is not required.

Adefovir
July 16, 2009 | Leave a Comment
Generic Name
Adefovir (ah-deh-FOE-veer)
Brand Name Hepsera
Type of Drug Antiviral.
Prescribed For
Chronic active hepatitis B in adults.
General Information
Hepatitis B is one of several different types of hepatitis, a viral infection of the liver. Adefovir is an antiviral drug that can reduce the amount of hepatitis B virus in the bloodstream and slow its spread to healthy liver tissue, however, it cannot cure chronic hepatitis B. People with chronic hepatitis B may develop liver cirrhosis or liver cancer and it is not known if adefovir can prevent these conditions from occurring. Like other viruses and bacteria, the hepatitis B virus can become resistant to the effects of adefovir.
Adefovir works against the hepatitis C virus in a way similar to that of certain human immunodeficiency virus (HIV) drugs. It interferes with an enzyme called reverse transcriptase, which is an essential component of the viral reproduction process. Almost half of each dose is eliminated via the urine within 24 hours of taking it.
Cautions and Warnings
Do not take adefovir if you are allergic or sensitive to any of its ingredients.
Adefovir can be toxic to the kidneys, especially in people who already have some kidney problems. Since it is eliminated from the body through the kidneys, people with kidney disease are often given lower doses of adefovir.
In some cases, hepatitis can become severely aggravated upon discontinuation of adefovir. Your doctor should check your liver for’ 2 weeks after the drug is stopped. it is possible that antiviral therapy may have to be re-started.
Adefovir has some activity against the human immunodeficiency virus (HIV). An HIV blood test is recommended before starting adefovir treatment. If you are HIV positive, adefovir could make the HIV virus resistant to future antiviral drugs.
People taking adefovir can develop liver disease, liver enlargement, fat degeneration, and lactic acidosis (potentially fatal metabolic imbalance). This may be a reason for your doctor to stop your adefovir treatment. This occurs most frequently in obese women.
Possible Side Effects
In studies, side effects reported in the treated group were similar in frequency to placebo.
✓ Most common: weakness, headache, stomach pain, and nausea.
✓ Less common: intestinal gas, diarrhea, and upset stomach.
Drug Interactions
This drug was studied extensively in an attempt to predict possible drug interactions. No major interaction problems have been revealed.
• Taking drugs that can be toxic to the kidneys (such as amino-glycosides, cyclosporine, nonsteroidal anti-inflammatory drugs (NSAIDs), tacrolimus, and vancomycin) together with adefovir can lead to the more rapid appearance of kidney damage.
• Ibuprofen, when taken in dosages of 800 mg 3 times a day, will increase adefovir blood levels by about 20 %, however the importance of this finding is unknown.
Food Interactions
Adefovir may be taken without regard to food or meals.
Usual Dose
Adults: 10 mg once a day. People with kidney disease requiring dialysis may take only 10 mg a week. The exact dosage is based on the severity of kidney disease.
Child: not recommended.
Overdosage
Gastrointestinal symptoms are the most likely outcome of an adefovir overdose. Take the victim to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Practice safe sex and safe needle use. People taking adefovir may still spread hepatitis B through sexual contact or by sharing needles. Practice safe sex using condoms and dental dams.
Do not share personal items that can have blood or body fluids on them, such as toothbrushes or razor blades.
Try to take adefovir at the same time every day.
Adefovir must be taken continuously to maintain its effectiveness. Be sure to keep enough adefovir on hand so that you do not run out of medicine.
If you take adefovir on a regular schedule and forget a dose, take it as soon as you remember. If it is almost time for your next dose, skip the forgotten dose and continue with your regular schedule. Do not take a double dose of this medicine. Call your doctor if you forget 2 or more doses in a row. Skipping or forgetting too many doses can make the hepatitis C virus resistant to adefovir.
Call your doctor at once if you feel very weak or tired, cold (especially in your arms and legs), dizzy or lightheaded, have unusual muscle pain, trouble breathing, stomach pain with nausea and vomiting, or have a fast or irregular heartbeat. These could be signs of lactic acidosis.
Call your doctor if you experience jaundice (symptoms include yellowing of the skin or whites of the eyes), appetite loss for a few days or more, lower stomach pain, nausea, dark urine, or bowel movements that are light in color. These could be signs of liver toxicity.
Special Populations
Pregnancy/Breast-feeding: Animal studies with adefovir have revealed a tendency for some birth defects when the dosage administered was more than 20 times the average human dose. There is no information on the effect of adefovir during pregnancy. The company that produces adefovir has established a registry to collect information on pregnant women who take this drug. When this drug is considered crucial by your doctor, its potential benefits may be carefully weighed against its risks.
It is not known if adefovir passes into breast milk. Nursing mothers who must take it should use infant formula.
Seniors: Seniors may be more sensitive to adefovir’s side effects because of the natural loss of kidney function that occurs with advancing age.

Brand Name
Adderall
Generic Ingredients
Dextroamphetamine Sulfate + Dextroamphetamine Saccharate + Amphetamine Aspartate + Amphetamine Sulfate
Other Brand Names Adderall XR
The information in this profile also applies to the following drugs:
Generic Ingredient.* Dextroamphetamine Sulfate RE Dexedrine Dextrostat
Generic Ingredient., Lisdexamfetamine Dimesylate Vyvanse
Type of Drug
Central-nervous-system (CNS) stimulant.
Prescribed For
Attention-deficit hyperactivity disorder (ADHD) and narcolepsy (uncontrollable desire to sleep).
General Information
Amphetamines are stimulants that work on the brain’s feeding center. Adderall, which is a mixture of two forms of amphetamine, may be used as a short-term aid in weight reduction. It should not be taken for longer than a few months for this purpose.
Amphetamines may also be prescribed for childhood ADHD, a condition characterized by distractibility, short attention span, hyperactive behavior, emotional instability, and difficulty controlling impulses. They should be used only after a complete evaluation of the child has been done. Frequency and severity of symptoms and their appropriateness for the age of the child determine whether drug therapy is required. Many experts believe that amphetamines offer only a temporary solution because they do not permanently change behavioral patterns. Psychological, educational, and social measures must also be taken to ensure successful treatment in the long term.
Cautions and Warnings
Do not take Adderall if you are allergic or sensitive to any amphetamine or have heart disease, a heart defect, high blood pressure, hardening of the arteries, liver or kidney disease, tics or Tourette’s syndrome, seizures or abnormal brain wave tests, thyroid disease, glaucoma, or a history of drug abuse.
Amphetamines should be used with extreme caution because they are highly addictive and easily abused.
New or worsening thought patterns, bipolar illness, aggressive or hostile behavior, psychotic behavior, and new manic symptoms can develop during treatment with amphetamines.
Stimulants like amphetamines are not effective and may be dangerous for children whose symptoms are related to environmental factors or primary psychiatric conditions, including psychosis.
Stimulants can cause weight loss and stunted growth in children under age 10. Blurred vision and difficulty focusing can occur.
Possible Side Effects
✓ Common: heart palpitations, restlessness, overstimulation, dizziness, sleeplessness, increased blood pressure, rapid heartbeat, upper abdominal pain, and weight loss.
✓ Less common: euphoria (feeling “high”), hallucinations, muscle spasms and tremors, headache, dry mouth, unpleasant taste in the mouth, diarrhea, constipation, upset stomach, nausea, vomiting, rash, itching, changes in sex drive, and impotence.
✓ Rare: psychotic drug reactions. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Combining an amphetamine and a monoamine oxidase inhibitor (MA01) antidepressant may cause a severe increase in blood pressure as well as bleeding inside the skull. Wait at least 2 weeks after stopping an MAGI before taking an amphetamine.
• Amphetamines may reduce the effectiveness of high blood pressure medicines.
• Gastrointestinal and urinary acidifying agents such as methenamine reduce the effectiveness of amphetamines.
• Gastroinstestinal alkalizing agents, such as sodium bicarbonate, and urinary alkalizing agents (acetazolamide, some thiazides) may increase and prolong the effects of amphetamines.
• Antipsychotic medications such as chlorpromazine, haloperidol, and lithium carbonate inhibit the stimulatory effects of amphetamines and can cause amphetamine poisoning.
• Amphetamines may enhance the effects of tricyclic antidepressants, norepinephrine, phenobarbital, phenytoin, and meperidine.
• Amphetamines may decrease the effectiveness of beta blockers.
• Amphetamines may counteract the sedative effect of antihistamines.
• Amphetamines can delay the absorption of ethosuximide into the bloodstream.
• Propoxyphene increases the CNS-stimulating effect of amphetamines. Fatal convulsions have occurred in propoxyphene overdose with amphetamines.

Generic Name
Acebutolol (ah-seh-BUTE-uh-lol) 91
Brand Name Sectral
Type of Drug
Beta-adrenergic blocking agent. Prescribed For
High blood pressure and abnormal heart rhythms.
General Information
Acebutolol hydrochloride is one of many beta-adrenergic blocking drugs, or beta blockers. These drugs interfere with the action of adrenaline and other chemicals in the body that affect many body functions. Individual beta blockers have different characteristics that can make them more suitable for certain conditions or people.
Cautions and Warnings
Do not take acebutolol if you are allergic or sensitive to any of its ingredients or to beta blockers.
You should be cautious about taking acebutolol if you have asthma, severe heart failure, a very slow heart rate, or heart block (disruption of the electrical impulses that control heart rate) because the drug may worsen these conditions.
People with angina taking acebutolol for high blood pressure risk aggravating their angina if they suddenly stop taking the drug. These patients should have their acebutolol dosage reduced gradually over 1-2 weeks.
Acebutolol should be used with caution if you have liver or kidney disease because your ability to eliminate this drug from your body may be impaired.
Acebutolol reduces the amount of blood pumped by the heart with each beat. This reduction in blood flow may aggravate the condition of people with poor circulation or circulatory disease.
If you are undergoing major surgery, your doctor may want you to stop taking acebutolol at least 2 days before surgery.
People with a history of severe anaphylactic reaction to alergens may be unresponsive to usual doses of epinephrine while taking beta blockers.
Possible Side Effects
Side effects are relatively uncommon and usually mild; normally they develop early in the course of treatment and are rarely a reason to stop taking acebutolol.
✓ Most common: fatigue.
✓ Common: dizziness and headache.
✓ Less common: chest pain, swelling in the legs or arms, depression, sleeplessness, abnormal dreams, rashes, constipation, diarrhea, upset stomach, stomach gas, nausea, frequent urination, back pain, joint and muscle pain, difficulty breathing, stuffy nose, and vision changes.
♦ Rare: cough, low blood pressure, slow heart beat, anxiety, impotence, changes in response to touch stimulation, itching, vomiting, abdominal pain, painful urination, nighttime urination, liver changes, sore throat, wheezing, eye irritation, pain or dry eye, and lupus erythematosus (extremely rare). Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Acebutolol may interact with surgical anesthetics to increase the risk of heart problems during surgery. Some anesthesiologists recommend gradually stopping the drug by 2 days before surgery.
• Acebutolol may interfere with the normal signs of low blood sugar and with the action of oral antidiabetes drugs.
• Acebutolol increases the blood-pressure-lowering effects of other blood-pressure-reducing agents, including clonidine, guanabenz, and reserpine, and calcium channel blockers such as nifedipine.
• Aspirin-containing drugs, nonsteroidal anti-inflammatory drugs (NSAIDS), and sulfinpyrazone may interfere with the blood-pressure-lowering effect of acebutolol.
• Cocaine may reduce the effectiveness of all beta blockers.
• Acebutolol may worsen the problem of cold hands and feet associated with ergot alkaloids, used to treat migraine. Gangrene is a possibility in people taking both an ergot and acebutolol.
• Acebutolol will counteract thyroid hormone replacements.
• Calcium channel blockers, flecainide, hydralazine, contraceptive drugs, cimetidine, propafenone, haloperidol, phenothiazine sedatives (molindone and others), quinolone antibacterials, and quinidine may increase the amount of acebutolol in the bloodstream and lead to increased acebutolol effects.
• Acebutolol should not be taken within 2 weeks of taking a monoamine oxidase inhibitor (MAGI) antidepressant.
• Acebutolol may interfere with the effects of some antiasthma drugs, including theophylline and aminophylline.
• Combining acebutolol with digitalis drugs may result in excessive slowing of the heart, possibly causing heart block.
• If you stop smoking while taking acebutolol, your dose may have to be reduced because your liver will break down the drug more slowly afterward.
• Aluminum salts, barbiturates, calcium salts, cholestyramine, colestipol, ampicillin, and rifampin may reduce the effectiveness of acebutolol.
• Beta blockers may block the effects of epinephrine.
Food Interactions
None known.

Acamprosate (ah-CAM-pro-sate)
Brand Name Cameral
Type of Drug
Synthetic neurochemical similar to the amino acid homotaurine.
Prescribed For Alcoholism.
General Information
Acamprosate is used to help alcoholic patients stay alcohol-free after they have stopped drinking. Unlike other drugs used to help people stay away from alcohol, it does not cause people to have a physical reaction to alcohol. Acamprosate restores the balance between two chemical systems in the brain, glutamate and GAGA, that are known to become unbalanced in alcoholics, but its exact action is not known. It may reduce alcohol craving. Acamprosate should be part of a program that includes counseling and support, and it should be started as soon as possible after alcohol withdrawal and continued even if the patient starts drinking again. This medication has not been proven to help patients if they are still drinking when they start treatment. Acamprosate has not been studied in patients who abuse other substances together with alcohol. Tolerance or addiction has not developed with acamprosate. It passes out of the body through the kidneys.
Cautions and Warnings
Do not take acamprosate if you are allergic or sensitive to any of its ingredients or if you have severe kidney disease. People with moderate kidney disease require a lower dosage of acamprosate.
Acamprosate does not eliminate or ease alcohol withdrawal symptoms.
People taking acamprosate may become depressed or have suicidal thoughts.
Acamprosate can affect your judgment, thinking, or coordination. Do not drive or operate dangerous machinery if you are taking this medicine.
