Aviptadil Dosage

Research-based dosing protocols, timing guidance, and reconstitution reference for Aviptadil. All information is for educational purposes only.

Quick Answer

Aviptadil is typically administered intravenously in critical care settings for ARDS at 50-150 pmol/kg/hour as a continuous infusion over 12 hours for 3 days. Investigational inhaled nebulized formulations range from 100-200 mcg 2-3 times daily. Dosing requires careful blood pressure monitoring due to hypotensive effects.

Standard Dosage Range

Research dosing range: 50-150 pmol/kg/hour (IV); 100-200 mcg (inhaled)

Educational reference only

These dosage ranges are derived from preclinical research and community protocols. No human clinical dose-ranging trials have established therapeutic doses for most research peptides. Always consult a qualified healthcare provider before starting any peptide protocol.

Dosage by Use Case

ARDS (Acute Respiratory Distress Syndrome)

50-150 pmol/kg/hourContinuous infusion over 12 hours
Duration

3 days

Slow IV infusion in ICU with continuous hemodynamic monitoring. Escalate dose from 50 to 100 to 150 pmol/kg/hour over 3 sequential 12-hour periods. Reduce/pause if systolic BP < 90 mmHg.

COVID-19 ARDS

50-150 pmol/kg/hourContinuous infusion over 12 hours
Duration

3 days

Specific trials used dose escalation as above. Monitor oxygenation parameters (PaO2/FiO2 ratio). Consider vasopressor support if hypotension develops.

Pulmonary Arterial Hypertension (investigational)

50-100 pmol/kg/hourContinuous infusion
Duration

Varies (acute challenge studies)

Acute hemodynamic challenge studies have evaluated VIP for pulmonary vasodilation effects in PAH. Long-term dosing not established.

COPD (Chronic Obstructive Pulmonary Disease; investigational)

100-200 mcg2-3× daily
Duration

Varies (clinical trials)

Inhaled nebulized formulation under investigation for bronchodilation and anti-inflammatory effects. Direct pulmonary delivery may minimize systemic hypotension.

Timing & Frequency

IV infusion is continuous. Inhaled formulations are typically administered evenly throughout the day. Given the short half-life (~1-2 minutes IV), continuous delivery is required for sustained effects.

Cycle Guidance

For ARDS, aviptadil is administered as a short course (3 days). Chronic use is not established. For investigational uses like COPD, longer cycles are being evaluated in clinical trials.

Frequently Asked Questions

What is the typical aviptadil dose for ARDS?
The standard intravenous dose for ARDS is 50-150 pmol/kg/hour, administered as a continuous infusion over 12 hours for 3 days in the ICU. Dose escalation is common, starting at 50 and increasing to 150 pmol/kg/hour based on blood pressure and oxygenation.
How is aviptadil administered?
Currently, aviptadil is primarily administered as a slow intravenous infusion in a critical care setting. Inhaled formulations are under investigation but not yet widely available.
What monitoring is required during aviptadil infusion?
Continuous hemodynamic monitoring (blood pressure, heart rate) is essential due to the risk of hypotension. Oxygenation parameters (PaO2/FiO2 ratio) should also be closely monitored.
Is there an oral form of aviptadil?
No, aviptadil is not available in oral form due to poor oral bioavailability and rapid degradation in the gastrointestinal tract. Intravenous and inhaled routes are used.
How quickly does aviptadil work?
Improvements in oxygenation may be seen within 24-72 hours of initiating aviptadil infusion in ARDS patients, based on clinical trial data.
Can aviptadil be used in children?
Aviptadil has not been extensively studied in pediatric populations. Dosing guidelines are not well-established for children.
