Published:

This essay has been submitted by a student. This is not an example of the work written by our professional essay writers.

The generic name of the drug being sold as Detrol LA is Tolterodine. Detrol LA is part of a class of drugs that are known as Cholinergic Receptor Blockers. Doctors prescribe this drug for patients suffering from urinary bladder disorders which in turn affect urination.

A person has conscious control over his bladder when he urinates. The nerves in the muscular wall of the urinary bladder release a chemical called acetyl choline, which attaches itself to the receptors on the muscle cells, thus enabling the bladder to contract. But patients with urinary bladder disorders lose this control and so may urinate without any warning. Detrol LA blocks the effect of acetyl choline on the urinary bladder muscles so that the sensation to urinate is reduced and this in turn prevents embarrassing situations for a patient due to uncontrolled urination. The generic drug, Tolterodine was approved by the FDA in 1998 and Detrol LA was approved in 2001.

Generally patients complain of the need to urinate frequently and incontinence, which are the symptoms of an "over active bladder". Doctors use Detrol LA to treat this condition. The minimum dosage given to a patient is 2mg twice daily. Detrol LA reacts adversely with medicines like erythromycin, nizoral, and miconazole. The effects of Detrol LA are unknown on the fetus and so it is safer for a pregnant woman to avoid it. But as Tolterodine traces were found in mother's milk in a study done on animals, it should be definitely avoided by nursing mothers.

The tips to be followed by patients while taking Detrol LA are:

The tablets should be swallowed whole preferably with water.

It can be taken either on an empty stomach or with food.

Even if a patient feels fine, he should continue the medicine.

If a patient misses a dose he should never take two doses together.

Among the side effects of Detrol LA, the most frequent one is dry mouth. Some other side effects are dizziness, constipation and abdominal pain.

Stability Personified Generic Depakote

The generic name for the drug Depakote is Valproic Acid, Divalproex Sodium and Sodium Valproate. The active e ingredient in the drug is Valproic acid. This drug received approval from the American authorities in 1978. It is used to treat patients with epileptic seizures, maniac depression or bipolar disorder as also migraine headaches. The drug is also known and sold as Depakene, Depacon Depakote ER and Divalproex.

Doctors prescribe this drug to stabilize the mood of the patient. Depakote acts by affecting the Gamma-amino butyric acid in the brain. This chemical also known as GABA is used by the nerves to communicate with each other. Depakote is available in various forms like capsules and tablets of differing dosage strengths from 125 mg to 500 mg. Other forms of Depakote available in the market are sprinkles syrups and even injections. In every 5ml of the syrup the content of Valproic acid is 250 mg and every 5 ml of injection contains 1000 ml of the drug.

A patient suffering from epileptic seizures starts with a low dosage of 10 to 15 mg per kg of body weight and the doctor slowly increases the dosage till the Valproic acid in the blood reaches the level of 50 to 100 mcg per ml. while patients suffering from bipolar disorder start with a high dosage of 750 mg, those treated for migraine headaches with Depakote have a dosage of 250mg twice daily of delayed release tablets to start with.

Depakote should not be used by pregnant women as it affects the fetus and the baby will be born with congenital cardio vascular problems, spina bifida as also neural tube defects. Depakote also reduces platelet count thus leading to the inability of the blood to clot as also abnormal bleeding.

While taking Depakote patients should consult their doctor if they encounter side effects like mild abdominal cramps, constipation or diarrhea, indigestion or loss of appetite, unusual weight gain or weight loss. Women may experience menstrual cycle changes as well.

Generic Diovan - A Boon to Hypertension Patients

The generic name of the medicine Diovan is Valsartan which is an oral medicine. It belongs to a class of drugs called ARBs or anqiotensin receptor blockers. It is used effectively in the treatment of hypertension and had been approved by the FDA in 1996.

The powerful anqiotensin converting enzyme (ACE) attaches itself to the angiotensin receptors in the muscle cells of the blood vessels which causes them to narrow down, thus leading to hypertension or high blood pressure. Diovan blocks the angiotensin receptors, dilates the blood vessels thus lowering the blood pressure of the patient.

The generic version of the drug Diovan will be available in the market only in the year 2012. It is used to treat hypertension and congestive heart failures, as also helping to improve survival rates after a heart attack. Diovan helps to work more efficiently. The drug is manufactured by Novartis pharmaceuticals and the patent for the drug Diovan prevents any pharmaceutical company from manufacturing the generic version of Diovan. However, there are a number of pharmaceutical companies that sell fake, sub- standard or spurious generic Diovan drugs which can be dangerous.

The active ingredient in Diovan is Valsartan which is also prescribed to patients with diabetes to protect them from kidney damage. The best thing for a patient not to miss a dose is to take the medicine at the same time every day. As Diovan raises potassium levels in the body, patients taking this medicine should avoid potassium supplements and salt substitutes that contain potassium without the doctor's permission.

Patients taking Diovan complain of side effects like dizziness and blurred vision. Increased potassium levels lead to muscle weakness or slow heart beats. If a patient experiences serious side effects like fainting, decreased sexual ability or very serious side effects like change in amount of urine passed, severe nausea and stomach pain or unusual fatigue, he should consult the doctor immediately.

This drug should be taken as per the doctor's instructions, after food. Discontinuing the medicine also should be done gradually under medical supervision.

Generic Effexor reacts adversely with Nardil and Parnate and these reactions can even assume a life threatening aura. Since the drug acts on the neurotransmitters in the brain, it slows down reflexes and impairs judgment so that the patient has to be extremely careful and cautious when he first begins treatment.

Generic Effexor increases the blood pressure and eye pressure of a person and so hypertension patients who suffer from glaucoma should be careful while taking this drug.

Generic Entocort-A Blessing for Crohn's Disease Patients

The drug Entocort is known by the generic name Budesonide. This is a synthetic steroid drug. Budesonide is like cortisol or hydrocortisone, a natural hormone produced in the body by the adrenal glands. Entocort is an effective anti- inflammatory drug and people suffering from Crohn's disease are treated with Entocort. Budesonide is the active ingredient in Entocort. It acts directly when it is in contact with the colon and the ileum and then it is taken to the liver where it is broken down and subsequently ejected from the system. As a result, the absorbed medicine is not distributed throughout the body. This causes very few side effects of Entocort.

The generic version of the drug Entocort is not yet available in the market. A patient needs to take only one tablet a day, for eight weeks to treat either a mild or moderately active Crohn's disease, as the disease attacks the second half of the small intestine and the colon.

Generally patients taking Entocort tolerate the medicine fairly well. However they mostly complain of side effects like headache and nausea, which are the side effects of having excess corticosteroid in the body. Other side effects include swelling in the ankles, acne, moon faces and getting bruised easily. Entocort may also lead to suppressing the body's own ability to make cortisol naturally and also causes bone breakdown. Budesonide interacts adversely with medicines like erythromycin, nizoral and indinavir to mention just a few. Although the doctors and scientists are not very sure whether Entocort and its main ingredient Budesonide will cause any abnormalities or congenital malformations in the fetus, it is safer if pregnant women avoid the drug. Since traces of the drug have been found in mother's milk, it is likely to adversely affect a baby being breast fed.

Taking Entocort with certain antibiotics or anti fungal medicines and even grape fruit or grape juice can increase levels of this medication in the blood.

As a result, no pharmaceutical company can manufacture the generic version of the drug Enablex till the patent expires in March 2015. So the earliest a pharmaceutical company can start manufacturing generic Enablex is in 2015.

Generally a patient suffering from over active bladder symptoms has a problem of frequent and unusually uncontrollable urinary bladder muscle contractions. Such a person suffers from urinary incontinence and a frequent need to urinate. Uncontrollable and frequent muscle contractions cause over active bladder symptoms.

In such cases the patient should contact the doctor immediately. Pregnant women and nursing mothers should take the doctor's advice before taking Enablex as the drug is likely to harm the baby.

Is Generic Evista A Cure for Osteoporosis? Yes, It Is!

Evista is an estrogen tablet whose active ingredient is raloxifene hydrochloride. Raloxifene hydrochloride is often referred to as a SERM Drug (Selective Estrogen Receptor Module Drug), as it binds estrogen receptors on the one hand and at the same time also activates some estrogen paths while blocking some others. A single Evista tablet comprises of 60 mg raloxifene hydrochloride.

This medication is prescribed by doctors to lower the incidence of breast cancer in post menopausal women who suffer from osteoporosis.

Serious side effects of Evista include problems like deep vein thrombosis, retinal vein thrombosis, as also pulmonary embolism.

But circumstances may further delay the availability of the generic version of Evista. Many pharmaceutical companies claim to sell the generic version of Evista online. But no one can be sure whether these drugs are safe and how genuine these drugs are. So it is safer to wait for the generic drug to be manufactured and sold after the patent for Evista expires. Evista adversely interacts with medicines like diazepam, cholesterol and thyroid medicines and oral contraceptives.

Generic Exforge - A Break-through In the Treatment of Hypertension

Amlodipine and Valsartan are the active ingredients found in the drug Exforge. This drug contains two medications in one tablet. A patient needs to take just one tablet a day and so this drug eliminates the need to take two tablets. The drug Exforge is now protected by a patent and so the generic version of the drug will be available only when the patent expires in September 2012. The responsibility of manufacturing and marketing Exforge lies solely with the pharmaceutical giant, Novartis.

Exforge works in two different ways. As Amlodipine is a calcium channel blocker and Valsartan an Angiotensin Receptor Blocker, these two medicines work in ways which are complementary to each other and also block the substances that causes the blood vessels to constrict as a result of which the blood pressure of the patient rises. Exforge helps to relax the blood vessels and dilates them thus lowering the blood pressure. The medicine should be taken according to the doctor's advice. Exforge is available in different dosage strengths like 5/160, 10/160, 5/320 and 10/320, where the numerator indicates the strength of Amlodipine and the denominator the strength of Valsartan.

Before beginning to take Exforge, a patient should tell the doctor about any medicines he is taking like prescription drugs, herbal products and even over the counter medicines. As Exforge harms the unborn baby and can even cause fetal death, pregnant women should avoid the drug. Nursing mothers too should avoid Exforge as the drug adversely affects the baby.
