General Information On Emtriva
Emtriva is an antiviral drug. It belongs to a category of HIV medicines known as reverse transcriptase inhibitors. Though it is not a cure for HIV or AIDS, it helps in preventing HIV cells from multiplying in the body (it prevents the HIV virus from entering the nucleus of healthy CD4 cells). Emtricitabine was approved by FDA to be used as an anti-HIV drug in 2003 for patients aged 18 years and above. The Emtriva drug is available in the form of capsules and can be consumed with or without food. Generally, doctors recommend a dosage of Emtriva 200mg capsules or 24ml oral solution daily.

The FDA has classified Emtriva as a pregnancy category B medicine. Though studies on animals have not demonstrated any danger to the foetus, there is no convincing proof that the use of generic Emtriva is safe for pregnant women. Further, research has not revealed if this medication is safe for nursing months.
The recommended dose of Emtriva in pediatric patients below the age of 3 months is 3 mg/kg daily once, to be administered as an oral solution. The dosage in an oral solution for children between 3 months to 17 years of age is 6 mg/kg and a maximum dosage of 240 mg (or 24 ml) daily once. In a capsule form, for the same age group (who can swallow a capsule) the dose is 200 mg/day, administered orally. In patients with renal impairment the dose for Emtriva is 200 mg/24 hours with creatinine clearance of > 50 mL/min; 200 mg/48 hours for creatinine clearance 30-49 mL/min; 200 mg/72 hours for creatinine clearance 15-29 mL/min; 200 mg/96 hours for creatinine clearance < 15 mL/min or for patients on hemodialysis.

What is a "Generic" medication/drug?
Generic drugs are medications that have 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 testing to ensure that they are similar to 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 the 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 the same 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 have a comparable strength and dosage as 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 equivalent. They may look different, and be called something different.
How are Generic drugs tested to ensure quality and efficacy?
Generally speaking, 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.
