Basic Information On Invirase
Invirase is used in highly active antiretroviral therapy (HAART) to treat patients with HIV (human immunodeficiency virus). The HIV virus requires an enzyme called HIV protease to reproduce and this drug inhibits the production of that enzyme thereby limiting the HIV virus. This enzyme is required for multiplication within the cell as well as for transfer of the mature viral particles to new cells. It is to be taken in conjunction with ritonavir to increase its bioavailability. The drug has been proven to be very beneficial in improving the lipid profile of HIV positive patients. The Invirase Drug helps contain both the HIV-1 and HIV-2 virus as it is a protease inhibitor.
Precautions/Side Effects For Invirase
There are very few side effects for saquinavir mesylate (Invirase). These include diarrhea, nausea, loose stools and other basic gastrointestinal symptoms. Slight abdominal discomfort, numbness and tingling sensation in the hands and legs might also be experienced. However, all these side effects should be very mild. In case you are experiencing aggravated symptoms, please seek immediate medical attention. The brand or generic Invirase is not known to react strongly with any other medication. However, Rifampin and Rifabutin are known to decrease Invirase levels.
Other drugs may react as well with this medicine. Therefore patients are advised to read the labels of other drugs to verify the same. Brand or generic Invirase contains saquinavir mesylate which is an antiretroviral drug. There are no definitive studies on the effects of this ingredient on pregnant women and hence should only use the drug if the risks are lesser than the benefits. The long term effects of the drug are not known at this time.
500mg of Invirase should be taken twice a day for adults over the age of 16 years. Recommended time is within 2 hours of a meal as this ensures complete absorption of the drug. It should not be taken on an empty stomach. The tablets should be kept at room temperature and never be frozen as they contain gel. In hot conditions, they may be refrigerated. The Invirase drug must be taken in conjunction with 100mg of ritonavir everyday. If a dose is missed, the next dose should be taken earlier than scheduled. However, it must not be doubled. When Invirase is taken with lopinavir/ritonavir, then additional 100mg of ritonavir is not required to be taken.

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.
