Entry Inhibitors (including Fusion Inhibitors) and CCR5 Co-receptor Antagonist

Entry Inhibitors
Entry inhibitors block HIV entry into CD4+ cells.

Fusion inhibitors
The only drug in this class is T-20, which is administered as a twice daily subcutaneous injection. The most common side effect is redness and pain at the site of injection. Rarely, infection can occur at the injection site. There also are reports of generalized allergic reactions.

CCR5 antagonist
Although there were some early concerns of liver inflammation for drugs in this class, MVC appeared to be well tolerated in clinical trials without any specific toxicities attributable to the drug. However, it is a new drug in a new class and the first to actually target the cell.

ABACAVIR - ORAL

(a-BAK-a-vir)

COMMON BRAND NAME(S): Ziagen

WARNING: In some patients, abacavir has caused a serious (sometimes fatal) allergic reaction. Your doctor may order a blood test to measure your risk before you start this medication or take it again. If the blood test shows you are at greater risk, your doctor should discuss the risks and benefits of abacavir and other treatment choices with you. Symptoms of an allergic reaction may include any of the following: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing, fever, extreme tiredness, nausea, vomiting, diarrhea, stomach pain, muscle aches, sore throat, or cough. Seek immediate medical attention if you experience any of these symptoms. If you have stopped taking abacavir because of an allergic reaction, you must never take any form of abacavir again. Notify all of your doctors and pharmacists if you have stopped taking abacavir due to an allergic reaction. Read the warning card provided with this medication for more details.

Rarely, abacavir has caused a severe (sometimes fatal) liver and blood problem (lactic acidosis). Immediately tell your doctor if you develop symptoms of liver problems (such as dark urine, persistent nausea/vomiting, stomach/abdominal pain, yellowing eyes/skin) or lactic acidosis (such as rapid breathing, drowsiness, muscle aches).

USES: Abacavir is used with other medications to help control your HIV infection, thereby improving your quality of life. It may also lower your risk of complications from HIV (such as new infections, cancers). Abacavir belongs to a class of drugs known as nucleoside reverse transcriptase inhibitors-NRTI.

Abacavir is not a cure for HIV infection, and it does not prevent the spread of HIV to others through sexual contact or blood contamination (such as sharing used needles).

HOW TO USE: Read the Medication Guide and Warning Card provided by your pharmacist before you start taking abacavir and each time you get a refill. Carry the Warning Card with you at all times. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth, usually 1-2 times daily with or without food or as directed by your doctor. If you are using the liquid form of this medication, carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.

Dosage is based on your medical condition and response to treatment.

If you stop using abacavir even for a short time and then restart the drug, you have an increased chance of developing a very serious (possibly fatal) allergic reaction. Refill your medication before you run out. Do not stop treatment unless directed by your doctor. Before restarting abacavir, consult your doctor or pharmacist, and be sure you have easy access to medical care.

If you are taking HIV medications for the first time, you may experience symptoms of an old infection as your immune system begins to work better. Tell your doctor immediately if you notice any trouble breathing, fever, new cough, vision problems, headaches, or skin problems.

It is very important to continue taking this medication (and other HIV medications) exactly as prescribed by your doctor. Do not skip any doses. Do not increase your dose, take this drug more often than prescribed, or stop taking it (or other HIV medicines) even for a short time unless directed to do so by your doctor. Skipping or changing your dose without approval from your doctor may cause the amount of virus to increase, make the infection more difficult to treat (resistant), or worsen side effects.

This medication works best when the amount of drug in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. To help you remember, take it at the same time(s) each day.

Tell your doctor if your condition does not improve or if it worsens.
