Approved Indications:

• Type 1 Diabetes Mellitus: For mealtime glycemic control as part of a basal-bolus regimen in adults and children.
• Type 2 Diabetes Mellitus: For adults requiring prandial insulin supplementation in combination with basal insulin or oral antidiabetic agents.
• Acute Hyperglycemia / Hospital Use: Can be used intravenously in hospital settings for rapid glucose control.

Clinically Accepted Off-Label Uses:

• Gestational Diabetes Mellitus (GDM): For pregnant patients when diet and exercise fail to maintain glycemic targets.
• Continuous Subcutaneous Insulin Infusion (CSII): Used in insulin pumps for precise prandial dosing.

• Route: Subcutaneous injection (preferred) or intravenous infusion (hospital use only).
• Timing: Administer within 15 minutes before a meal or within 20 minutes after starting a meal.
• Adult Dosing: Individualized based on blood glucose, carbohydrate intake, and prior insulin requirements. Typical prandial dose ranges from 0.05 to 1.0 units/kg/day as part of basal-bolus regimen.
• Pediatric Dosing: Individualized; dosing is adjusted according to age, weight, and glucose monitoring.
• Elderly / Renal / Hepatic Impairment: Start with lower doses; monitor blood glucose closely; titrate cautiously to avoid hypoglycemia.
• IV Administration: For hospital use (e.g., DKA), initiate under continuous monitoring; adjust according to frequent glucose checks.
• Special Notes: Rotate injection sites to prevent lipodystrophy. Use compatible insulin pen devices or syringes.

Insulin Glulisine is a rapid-acting insulin analog engineered with amino acid modifications that prevent hexamer formation, promoting rapid absorption after subcutaneous injection. It binds to insulin receptors on muscle, liver, and adipose tissue, activating receptor tyrosine kinase activity. This signaling cascade enhances GLUT4 translocation to the cell surface, increasing glucose uptake, promoting glycogen synthesis, and inhibiting hepatic gluconeogenesis. It also suppresses lipolysis and proteolysis, leading to a rapid reduction in postprandial blood glucose levels.

• Absorption: Rapid after SC injection; onset ~10–20 minutes.
• Peak Effect: 60–90 minutes post-injection.
• Duration: Approximately 3–5 hours.
• Distribution: Predominantly in extracellular fluid; minimal protein binding.
• Metabolism: Degraded by insulinases in liver, kidneys, and muscle.
• Half-Life: Plasma half-life ~1 hour; biological effect lasts several hours.
• Elimination: Metabolites excreted primarily via renal clearance.
• IV Use: Immediate onset; effect duration depends on infusion rate.

• Pregnancy: Considered safe for use during pregnancy when tight glycemic control is needed. Helps reduce maternal and fetal complications associated with hyperglycemia.
• Lactation: Excreted in breast milk in negligible amounts; orally inactive in infants; generally considered safe.
• Caution: Frequent blood glucose monitoring required during pregnancy and postpartum.

• Primary Class: Antidiabetic agent.
• Subclass: Rapid-acting insulin analog.

• Known hypersensitivity to insulin glulisine or any excipients.
• Active hypoglycemia.
• Use in unmonitored IV settings outside hospital protocols.

• Hypoglycemia: Most frequent and serious adverse effect; patient education and glucose monitoring essential.
• Hypokalemia: Monitor potassium in patients receiving high doses or IV insulin.
• Injection-Site Reactions: Monitor for lipodystrophy, redness, or swelling; rotate injection sites.
• Pump Therapy: Risk of infusion set occlusion; ensure proper device functioning.
• Illness or Stress: May require dose adjustments due to altered insulin sensitivity.
• Switching Insulins: Requires careful monitoring and dose adjustment to prevent hypo- or hyperglycemia.

Common:

• Hypoglycemia.
• Injection site reactions (pain, erythema, lipohypertrophy).

Less Common:

• Weight gain.
• Mild edema.

Rare but Serious:

• Severe allergic reactions, including anaphylaxis.
• Immune-mediated insulin resistance.

Timing:

• Hypoglycemia most likely during postprandial peak (60–90 minutes after injection).

• Increase Hypoglycemia Risk: Oral antidiabetics, beta-blockers, salicylates, alcohol.
• Increase Hyperglycemia Risk: Corticosteroids, thyroid hormones, sympathomimetics, diuretics.
• Beta-blockers: May mask symptoms of hypoglycemia.
• Pharmacokinetic Interactions: Minimal; not metabolized by CYP450 enzymes. Most interactions are pharmacodynamic.

• Rapid-acting insulin analogs like glulisine are recommended for postprandial glucose control in both type 1 and type 2 diabetes.
• Continuous glucose monitoring integration with insulin glulisine is increasingly emphasized for precise glycemic control.
• Insulin glulisine is preferred over regular insulin in hospital settings when rapid correction of hyperglycemia is required.

• Unopened Vials/Pens: Refrigerate at 2°C–8°C; do not freeze.
• In-Use Vials/Pens: May be stored at room temperature (below 30°C) for up to 28 days.
• Protection: Keep away from direct light and heat.
• Handling: Do not shake vigorously; roll gently if resuspension is needed.
• IV Solutions: Prepare immediately before use; discard unused portions.
