**Fuzeon (Enfuvirtide) Overview:**<\/p>\n
**Classification:**
\n– **Type:** HIV Fusion Inhibitor (Entry Inhibitor)
\n– **Use:** Antiretroviral combination therapy for HIV-1 infection<\/p>\n
**Mechanism of Action:**
\n– Enfuvirtide disrupts the fusion of the HIV-1 virus with CD4+ host cells by targeting **gp41**, a transmembrane protein vital for the virus’s fusion mechanism.
\n– By binding to **gp41**, enfuvirtide prevents the formation of an entry pore, halting the virus from injecting its genetic material into the host cell.<\/p>\n
<\/p>\n
**Warnings and Precautions**
\n1. **Injection Site Reactions (ISRs):**
\n– Almost all patients (98%) report ISRs, such as pain, redness, nodules, and bruising.
\n2. **Biojector\u00ae 2000 Use:**
\n– Increased risks of neuralgia, bruising, hematomas, and bleeding (not recommended for patients on anticoagulants or with coagulation disorders).
\n3. **Pneumonia Risk:**
\n– Monitor for symptoms, particularly in patients with low CD4 counts or other predispositions.
\n4. **Hypersensitivity Reactions:**
\n– Discontinue immediately if signs of systemic hypersensitivity (rash, fever, respiratory symptoms) occur.
\n5. **Immune Reconstitution Syndrome:**
\n– Potential emergence of inflammatory conditions when immune function improves during combination therapy.<\/p>\n
### **Common Side Effects**
\n– Local ISRs (e.g., pain, erythema)
\n– Diarrhea
\n– Nausea
\n– Fatigue<\/p>\n
**Severe Adverse Reactions:**
\n– Rare hypersensitivity reactions
\n– Possible pneumonia<\/p>\n
### **Drug Interactions**
\n– No dose adjustment required when combined with other antiretrovirals or non-antiretroviral drugs.<\/p>\n
### **Use in Specific Populations**
\n1. **Pregnancy:**
\n– No evidence of fetal harm in animal studies; use only if necessary.
\n2. **Breastfeeding:**
\n– Avoid due to potential HIV transmission via breast milk.
\n3. **Pediatric Use:**
\n– Not established for children <6 years. Limited efficacy and safety data for those \u22656 years.
\n4. **Geriatric Use:**
\n– Insufficient data for patients aged \u226565 years.<\/p>\n","protected":false},"excerpt":{"rendered":"
