đŸ‘¨â€âš•ī¸

Adult Dosing

Standard Dose: Highly individualized based on patient's metabolic needs, blood glucose monitoring, and glycemic goals. Typically administered subcutaneously once or twice daily.
Dose Range: 0.3 - 0.6 mg

Condition-Specific Dosing:

Type 1 Diabetes: Initial total daily dose often 0.5-1.0 units/kg/day, with Novolin 70/30 typically given as 2/3 of the total daily dose in the morning and 1/3 in the evening, or as directed by physician.
Type 2 Diabetes: Initial dose often 0.2-0.4 units/kg/day, adjusted based on blood glucose response. May start with 6-10 units once or twice daily before meals.
đŸ‘ļ

Pediatric Dosing

Neonatal: Not established (use specific insulin regimens for neonates)
Infant: Dosing highly individualized based on weight and metabolic needs. Close monitoring required.
Child: Dosing highly individualized based on weight, pubertal status, and metabolic needs. Typical starting dose for Type 1 Diabetes is 0.5-1.0 units/kg/day, adjusted based on blood glucose.
Adolescent: Dosing highly individualized, often higher during puberty due to insulin resistance. Typical range 0.8-1.2 units/kg/day for Type 1 Diabetes.
âš•ī¸

Dose Adjustments

Renal Impairment:

Mild: Insulin requirements may decrease; monitor blood glucose closely.
Moderate: Insulin requirements typically decrease; dose reduction and close monitoring of blood glucose are necessary.
Severe: Significant dose reduction often required; monitor blood glucose frequently to avoid hypoglycemia.
Dialysis: Insulin requirements may be significantly reduced; dose adjustment based on blood glucose monitoring and clinical response.

Hepatic Impairment:

Mild: Insulin requirements may decrease; monitor blood glucose closely.
Moderate: Insulin requirements typically decrease due to reduced gluconeogenesis and insulin clearance; dose reduction and close monitoring are necessary.
Severe: Significant dose reduction often required; monitor blood glucose frequently to avoid hypoglycemia.

Pharmacology

đŸ”Ŧ

Mechanism of Action

Insulin lowers blood glucose by stimulating peripheral glucose uptake, especially by skeletal muscle and fat, and by inhibiting hepatic glucose production. It inhibits lipolysis and proteolysis, and enhances protein synthesis. Insulin Regular provides rapid onset of action, while Insulin NPH provides an intermediate duration of action.
📊

Pharmacokinetics

Absorption:

Bioavailability: Approximately 50-60% (subcutaneous, highly variable)
Tmax: Insulin Regular: 1.5-2.5 hours; Insulin NPH: 4-12 hours. For Novolin 70/30, peak effect is typically 2-12 hours.
FoodEffect: Administered before meals; food intake affects postprandial glucose, requiring appropriate insulin dosing.

Distribution:

Vd: Approximately 0.1-0.2 L/kg
ProteinBinding: Low (approximately 0-9%)
CnssPenetration: Limited

Elimination:

HalfLife: Insulin Regular: 5-10 minutes (plasma half-life); Insulin NPH: 1-2 hours (plasma half-life). Functional half-life is longer due to absorption kinetics.
Clearance: Primarily renal clearance (approximately 50% of total clearance), also hepatic.
ExcretionRoute: Renal (metabolites)
Unchanged: Less than 5% (excreted unchanged)
âąī¸

Pharmacodynamics

OnsetOfAction: Approximately 30 minutes (due to Regular insulin component)
PeakEffect: Approximately 2-12 hours (due to combined Regular and NPH components)
DurationOfAction: Approximately 18-24 hours (due to NPH insulin component)
Confidence: Medium

Monitoring

đŸ”Ŧ

Baseline Monitoring

HbA1c

Rationale: To establish baseline glycemic control and guide initial therapy.

Timing: Prior to initiation of therapy.

Fasting Plasma Glucose (FPG)

Rationale: To establish baseline glucose levels.

Timing: Prior to initiation of therapy.

Renal function (SCr, eGFR)

Rationale: Insulin clearance is primarily renal; impairment may necessitate dose adjustment.

Timing: Prior to initiation of therapy.

Hepatic function (ALT, AST)

Rationale: Insulin is metabolized in the liver; impairment may necessitate dose adjustment.

Timing: Prior to initiation of therapy.

📊

Routine Monitoring

Self-Monitoring Blood Glucose (SMBG)

Frequency: Multiple times daily (e.g., pre-meal, 2-hour post-meal, bedtime, overnight) as directed by healthcare provider.

Target: Individualized, typically 80-130 mg/dL pre-meal, <180 mg/dL post-meal.

Action Threshold: Hypoglycemia (<70 mg/dL) or persistent hyperglycemia (>180-250 mg/dL) requiring dose adjustment.

HbA1c

Frequency: Every 3-6 months, or more frequently if glycemic control is suboptimal or therapy is changed.

Target: Individualized, typically <7% for most adults.

Action Threshold: Above target range indicates need for therapy adjustment.

Signs and symptoms of hypoglycemia/hyperglycemia

Frequency: Daily, ongoing.

Target: Absence of symptoms.

Action Threshold: Presence of symptoms requires immediate action (e.g., glucose intake for hypoglycemia, medical evaluation for persistent hyperglycemia).

đŸ‘ī¸

Symptom Monitoring

  • Hypoglycemia: sweating, shakiness, dizziness, confusion, hunger, irritability, headache, blurred vision, rapid heartbeat, anxiety, weakness, slurred speech, seizures, unconsciousness.
  • Hyperglycemia: increased thirst, increased urination, fatigue, blurred vision, headache, nausea, vomiting, abdominal pain (especially in DKA).

Special Patient Groups

🤰

Pregnancy

Insulin is the preferred treatment for managing diabetes in pregnant women, as it does not cross the placenta in significant amounts. Close monitoring of blood glucose is essential, and insulin requirements may change throughout pregnancy.

Trimester-Specific Risks:

First Trimester: Insulin requirements may decrease due to nausea/vomiting; risk of hypoglycemia.
Second Trimester: Insulin requirements typically increase due to increasing insulin resistance.
Third Trimester: Insulin requirements continue to increase, often peaking in the late third trimester.
🤱

Lactation

Insulin is compatible with breastfeeding. It is not excreted into breast milk in clinically significant amounts and poses no risk to the breastfed infant.

Infant Risk: L1 (Safest - no increase in adverse effects in infants)
đŸ‘ļ

Pediatric Use

Dosing is highly individualized and requires careful titration based on age, weight, pubertal status, and glycemic control. Children and adolescents may have varying insulin sensitivities and are at higher risk for hypoglycemia.

👴

Geriatric Use

Increased risk of hypoglycemia due to potential for impaired renal/hepatic function, reduced counter-regulatory responses, and polypharmacy. Start with lower doses and titrate carefully. Close monitoring of blood glucose is crucial.

Clinical Information
