Intradialytic Parenteral Nutrition (IDPN)
Nutritional Support for Malnourished Hemodialysis Patients
Pharmko's Intradialytic Parenteral Nutrition (IDPN) therapy delivers essential nutrients to patients undergoing dialysis who are struggling with malnutrition. Formulated and compounded based on each patient's clinical profile, IDPN is administered during regular dialysis sessions to improve nutritional status and support better outcomes.
Intradialytic Parenteral Nutrition (IDPN)
Intradialytic Parenteral Nutrition (IDPN) is a form of supplemental nutrition delivered intravenously during hemodialysis sessions to treat malnourished dialysis patients who cannot meet their nutritional needs through oral intake or supplements alone.
How IDPN Works:
IDPN solutions containing amino acids, glucose, and lipids are infused directly into the venous drip chamber of the hemodialysis machine during the patient's regular dialysis treatment. This approach provides:
No Additional IV Access Required
Uses the existing dialysis circuit—no separate line needed
Convenience for Patients
Administered 3x/week during regularly scheduled dialysis sessions
Supplemental Nutrition
Typically delivers 800-1,200 calories per session
Minimal Workflow Disruption
Integrates seamlessly into dialysis center operations
Clinical Context: Malnutrition in Hemodialysis
Malnutrition affects 20-60% of hemodialysis patients and is one of the strongest predictors of mortality and morbidity in this population. Protein-energy wasting (PEW) results from:
Poor appetite and decreased oral intake
Chronic inflammation and metabolic acidosis
Protein loss during dialysis
Increased catabolism from uremia
Dietary restrictions (low potassium, low phosphorus)
IDPN is recommended when dietary counseling and oral supplements fail to improve nutritional status.
Clinical Indications: When to Consider IDPN
IDPN is appropriate for hemodialysis patients with protein-energy wasting who have not responded to first-line nutritional interventions.
Stepwise Approach to Renal Malnutrition
Clinical guidelines recommend the following progression:
1
Dietary Counseling
Renal dietitian provides individualized nutrition plan
2
Oral Nutritional Supplements (ONS)
Renal-specific oral supplements to increase protein/calorie intake
3
IDPN Therapy
When Steps 1 & 2 are insufficient or not tolerated
Clinical Criteria for IDPN
Lab & Clinical Indicators
Patients typically present with:
Serum albumin <3.5 g/dL (persistently low despite interventions)
Adequate dialysis: Kt/V ≥1.25 (hemodialysis adequacy)
Unintentional weight loss (>5% in 3 months or >10% in 6 months)
Low prealbumin or transferrin
Decreased muscle mass (mid-arm circumference, hand grip strength)
Patient Characteristics
IDPN candidates often have:
Poor oral intake despite dietary counseling
Intolerance to oral supplements (GI symptoms)
Anorexia or early satiety
Chronic inflammation (elevated CRP)
High catabolic state (infection, wounds)
Multiple comorbidities increasing metabolic demand
IDPN is recommended when dietary counseling and oral supplements fail to improve nutritional status.
Important: IDPN is not a substitute for addressing underlying causes of malnutrition (underdialysis, inflammation, acidosis). These should be optimized alongside IDPN therapy.
How Pharmko Delivers Personalized IDPN Support
From Referral to Dialysis Integration: Our Streamlined Clinical Process
1
Nutritional Assessment & Referral
Nephrologists or renal dietitians identify appropriate patients and submit detailed clinical documentation for Pharmko's review, including:
Current lab values (albumin, prealbumin, CBC, CMP)
Dialysis adequacy (Kt/V)
Documentation of failed dietary counseling/ONS trials
Weight history and nutritional assessment
2
Customized IDPN Compounding
Pharmko's clinical pharmacists prepare individualized IDPN formulations tailored to each patient's needs:
Amino acids: Typically 10% solution, providing essential and non-essential amino acids
Dextrose: 40-50% glucose for energy
Lipid emulsion: 10-20% fat for essential fatty acids and calories
Vitamins & minerals: Renal-appropriate micronutrients
Each formula is customized based on the patient's weight, lab results, dialysis prescription, and comorbidities.
3
Dialysis Integration
IDPN is delivered with a multi-function infusion pump that integrates seamlessly into dialysis workflows:
No additional IV setup: Infuses through venous drip chamber of dialysis circuit
No IV poles required: Pump clamps directly onto dialysis machine
Timed infusion: Administered over 3-4 hours during dialysis session
Minimal staff burden: Simple setup, low maintenance
Pharmko provides brief on-site training for dialysis center staff.
4
Scheduled Delivery & Supply Management
Formulations and supplies are shipped regularly to dialysis centers, timed with the patient's treatment plan:
Weekly or bi-weekly deliveries (patient receives IDPN 3x/week)
Temperature-controlled packaging maintains stability
All necessary supplies included (tubing, filters, syringes)
Automated refill coordination to prevent shortages
5
Responsive Coordination & Monitoring
Our clinical team works hand-in-hand with dialysis center staff and providers to optimize therapy:
Lab review: Clinical pharmacists review monthly labs and recommend formula adjustments

IDPN — Who It's For
Dialysis Patients with Malnutrition
Patients receiving hemodialysis who are unable to meet their daily protein and caloric needs through oral intake alone, despite dietary counseling and oral supplement trials.
Unintentional Weight or Muscle Loss
Those experiencing progressive weight loss, muscle wasting, or fatigue related to protein-energy wasting (PEW) or chronic inflammation, with albumin persistently below 3.5 g/dL.
Poor Appetite or Low Nutritional Intake
Patients with anorexia, gastrointestinal symptoms (nausea, early satiety), or strict dietary restrictions that make it difficult to consume adequate nutrients orally.
High Metabolic Demand
Dialysis patients with increased nutritional needs due to infections, wounds, multiple comorbidities, or high catabolic states that exceed what oral intake can provide.
IDPN — Who It's For
What is parenteral nutrition for dialysis patients?
Parenteral nutrition for dialysis patients refers to intravenous nutrition delivered to hemodialysis patients who cannot meet their nutritional needs through eating or oral supplements. The most common form is Intradialytic Parenteral Nutrition (IDPN), which is administered during dialysis sessions by infusing nutrients directly into the dialysis circuit.
IDPN provides amino acids, glucose, lipids, vitamins, and minerals without requiring a separate IV line. It's recommended after dietary counseling and oral supplements have failed to improve nutritional status.
What is the difference between TPN and IDPN?
TPN IDPN
Scope Complete nutrition (100% of needs) Supplemental nutrition (partial)
When Given Continuously or overnight at home Only during dialysis (3x/week)
IV Access Requires central venous catheter Uses dialysis circuit (no extra line)
Patient Type Non-functional GI tract Hemodialysis patients with malnutrition
Calories 1,500-2,500+ per day 800-1,200 per session (3x/week)
IDPN is for hemodialysis patients who can still eat but can't get enough nutrition orally. TPN is for patients who cannot use their digestive system at all.
Can you get PPN at home?
Peripheral Parenteral Nutrition (PPN) is typically administered in hospital settings for short-term use (less than 2 weeks). While technically possible at home with appropriate training, PPN is rarely used for long-term home therapy because:
It requires peripheral IV access, which has higher risk of phlebitis and infiltration
Lower concentration formulas (due to peripheral vein limitations) provide fewer calories
Frequent IV site changes are needed
For long-term home parenteral nutrition, Total Parenteral Nutrition (TPN) via central line is preferred.
For hemodialysis patients specifically, IDPN is the most practical option because it uses the existing dialysis access and is administered at the dialysis center during regularly scheduled treatments.
What are the risks of IDPN?
IDPN is generally safe when properly monitored. Potential risks include:
Metabolic Risks:
Hyperglycemia: Rapid glucose infusion during dialysis can raise blood sugar, especially in diabetic patients (managed with insulin if needed)
Electrolyte imbalances: Monitored through regular lab work and formula adjustments
Hyperlipidemia: Elevated triglycerides from lipid infusions (less common with modern formulations)
Catheter-Related Risks:
IDPN uses the existing dialysis access, so there is no additional infection risk beyond standard dialysis catheter care
Other Considerations:
Fluid overload: IDPN formulations are designed to minimize fluid volume; dialysis prescription may be adjusted
Refeeding syndrome: Rare in IDPN; gradual introduction of therapy reduces risk
Importantly, IDPN does NOT appear to increase infection risk compared to standard TPN, because it uses the dialysis circuit rather than a separate central line. Clinical monitoring (monthly labs, weight tracking) minimizes metabolic risks.
