General Information on Lopressor
Lopressor is indicated for the treatment of high blood pressure. This drug is also used for relieving symptoms of chest pain (angina). The generic name of this drug is Metoprolol. It comes under a category of drugs referred to as beta blockers.
Lopressor works by improving the circulation of blood. When blood is circulated efficiently the pressure on the heart decreases and it starts to beat more easily. This, in turn, helps in reducing increased blood pressure.
Lopressor is available in form of oral tablets which come in following two strengths, Lopressor 50 mg and Lopressor 100 mg. In addition to Metoprolol, oral tablets also contain the following inactive ingredients: cellulose compounds, magnesium stearate, titanium dioxide, polyethylene glycol, colloidal silicon dioxide, lactose, propylene glycol, talc, povidone, and sodium starch glycolate. Lopressor is also available in form 5 ml solution for intravenous use.
Side effects of Lopressor
You should not buy Lopressor if you have a known hypersensitivity to Metoprolol or are unable to urinate. In addition, patients who have the following conditions should also not buy Lopressor: a tumor of adrenal gland, a blood circulation disorder, a serious heart condition such as severe heart failure, sick sinus syndrome and AV block.
Before starting treatment inform your doctor if you have/had any of the following conditions: glaucoma, heart failure, bronchitis, asthma, gout, a thyroid disorder, diabetes, liver disease, lupus, or kidney disease. If you suffer from any of the above, your doctor may ask you to undergo certain tests to establish the safety of Metoprolol in your case.
Side effects of Lopressor may include, but are not limited to, the following: gastrointestinal stress, blurred vision, sore throat, ringing in the ears, vision problems, eye pain, increased urination, signs of liver damage (dark urine, black stools, yellowing of the eyes or skin, nausea, stomach pain), drowsiness, weakness, easy bruising, or uneven heartbeat.
Dosage of Lopressor
The recommended dosage for the treatment of hypertension is Lopressor 100 mg per day administered as a single dose or two equal doses. The recommended dosage range for relieving angina symptoms is 50 mg– 100 mg.
However, your actual dosage may be different from the recommended dosage. The actual dosage of this drug is calculated after taking into account various factors such as patient’s age, medical history, severity of the condition that is being treated, and response to the drug. It is imperative that you follow your doctor’s recommendation.
Lopressor may interact with various drugs. You should inform your doctor if you are taking the following drugs: alpha blockers (such as Phentolamine, Phenoxybenzamine, Labetolol, and others), calcium channel blockers (such as Nimodipine, Felodipine, Verapamil, Nicardipine, and others), certain antidepressants (such as Sertraline, Paroxetine, Duloxetine, and others), certain antipsychotic drugs (such as Thioridazine, Haloperidol, and Chlorpromazine), certain arrhythmia drugs (such as Quinidine, Disopyramide, Lidocaine, and others), or NSAIDs (Meloxicam, Naproxen, Ketorolac, and others).

What is a "Generic" medication/drug?
Generic drugs are medications that have the comparable medicinal ingredients as the original brand name drug, but which are generally cheaper in price. Nearly 1 in 3 drugs dispensed are "generic". They undergo comparative testing to ensure that they are the same as their "brand" counterparts in:
- Active Ingredient (e.g. "Pravastatin" is the active ingredient in brand name Pravachol)
- Dosage (e.g. 10 mg of the active ingredient)
- Safety (e.g. same or similar side effects, drug interactions)
- Performance (e.g. 10 mg of a "generic" can be substituted for 10 mg of the "brand" and have the same therapeutic result)
- Intended use (e.g. both "generic" and "brand" would be prescribed for the same conditions)
What this means is that "generic" medications can be used as a substitute of their brand equivalents with comparable therapeutic results. There are a few exceptions (examples are outlined at the end of this page) and as always you should consult your physician before switching from a brand name medications to a generic or vice versa.
What differences are there between generic and brand?
While generics and brand equivalent drugs contain comparable active ingredients, they may be different in the following ways:
- Appearance (e.g. the scoring or markings)
The color, shape and size of the medication come from the fillers that are added to the active ingredients to make the drug. These fillers that are added to the drug have no medical use and do not to change the effectiveness of the final product. A generic drug must contain comparable active ingredients and must be comparable in strength and dosage to the original brand name equivalent. Generic drugs can be more cost effective than purchasing the brand name.
Why do generics cost less than the brand name equivalents?
When a new drug is "invented", the company that discovered it has a patent on it that gives them the exclusive production rights for this medication. Once the patent expires in a country, other companies can bring the product to market under their own name. This patent prevents other companies from copying the drug during that time so they can earn back their Research and Development costs through being the exclusive supplier of the product. After the patent expires however, other companies can develop a "generic" version of the product. These versions generally are offered at much lower prices because the companies do not have the same development costs as the original company who developed the medication.
The main thing to realize here though is that the two products are therapeutically comparable. They may look different, and be called something different, but they are required to be have the same active ingredient.
How are Generic drugs tested to ensure quality and efficacy?
The two most generally accepted methods to prove the safety of a generic version of a drug are to either repeat most of the chemistry, animal and human studies originally done, or to show that the drug performs comparably with the original brand name drug. This second option is called a "comparative bioavailability" study. During this type of study, volunteers are given the original drug, and then separately later the generic drug. The rates at which the drug is delivered to the patient (into their blood stream or otherwise absorbed) are measured to ensure they are the same. Because the same active ingredient is used the major concern is just that it delivers the common chemical(s) at the same rate so that they have the same effect. Please note that the methods that the manufacturers use may vary from country to country.
