Pramlintide Acetate

Generic Name: pramlintide acetate

Over-the-Counter (OTC)

Brand Names:

Symlinpen

11 DESCRIPTION SYMLIN ® (pramlintide acetate) injection is an anti-diabetic medication for use in patients with diabetes treated with insulin. Pramlintide is a synthetic analog of human amylin, a naturally occurring neuroendocrine hormone synthesized by pancreatic beta cells that contributes to glucose control during the postprandial period.

Overview

11 DESCRIPTION SYMLIN ® (pramlintide acetate) injection is an anti-diabetic medication for use in patients with diabetes treated with insulin. Pramlintide is a synthetic analog of human amylin, a naturally occurring neuroendocrine hormone synthesized by pancreatic beta cells that contributes to glucose control during the postprandial period.

Uses

1 INDICATIONS AND USAGE SYMLIN is indicated as an adjunctive treatment in patients with type 1 or type 2 diabetes who use mealtime insulin therapy and who have failed to achieve desired glucose control despite optimal insulin therapy. SYMLIN is an amylin analog indicated for patients with type 1 or type 2 diabetes who use mealtime insulin and have failed to achieve desired glycemic control despite optimal insulin therapy (1) .

Dosage

2 DOSAGE AND ADMINISTRATION • Upon initiation of SYMLIN, reduce mealtime insulin dose by 50%. Monitor glucoses frequently and individualize subsequent insulin dose adjustments (2.1) . • Type 1 Diabetes: Start at 15 mcg subcutaneously before major meals. Increase in 15 mcg increments to a maximum premeal dose of 30 or 60 mcg; if not tolerated, reduce to 30 mcg, as tolerated (2.2) . • Type 2 Diabetes: Start at 60 mcg subcutaneously before major meals then increase to 120 mcg before meals, as tolerated (2.2) . • Wait at least 3 days between dose titrations to minimize nausea (2.1) . 2.1 Important Considerations Pertaining to SYMLIN and Insulin Dose Adjustments SYMLIN dosage differs depending on whether the patient has type 1 or type 2 diabetes [see Dosage and Administration (2.2 , 2.3) ].

Side Effects

6 ADVERSE REACTIONS Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. • Most common adverse reactions (incidence ≥5% and higher incidence than placebo): nausea, vomiting, anorexia, headache (6.1) .

Interactions

7 DRUG INTERACTIONS 7.1 Insulin The pharmacokinetic parameters of pramlintide are altered when SYMLIN is mixed in the same syringe with regular, NPH, and 70/30 premixed formulations of recombinant human insulin. SYMLIN and insulin must not be mixed and must be administered as separate injections [see Dosage and Administration (2.4) , Warnings and Precautions (5.4) , and Clinical Pharmacology (12.3) ]. 7.2 Oral Medications SYMLIN has the potential to delay the absorption of concomitantly administered oral medications.

Warnings

WARNING: SEVERE HYPOGLYCEMIA SYMLIN use with insulin increases the risk of severe hypoglycemia, particularly in patients with type 1 diabetes. When severe hypoglycemia occurs, it is seen within 3 hours following a SYMLIN injection. Serious injuries may occur if severe hypoglycemia occurs while operating a motor vehicle, heavy machinery, or while engaging in other high-risk activities. 5 WARNINGS AND PRECAUTIONS • Severe hypoglycemia: Increased risk particularly for type 1 diabetes. Upon initiation of SYMLIN, reduce mealtime insulin dose by 50% and frequently monitor blood glucoses (5.2) . • Never share a SymlinPen between patients, even if the needle is changed (5.3) . • Do not mix SYMLIN and insulin: Mixing can alter the pharmacokinetics of both products. Administer as separate injections (5.4 , 7.1) . • Slows gastric emptying: Administer concomitant oral medications at least 1 hour before or 2 hours after SYMLIN if rapid onset or threshold concentration is critical (5.6 , 7.2) . 5.1 Patient Selection Proper patient selection is critical to the safe and effective use of SYMLIN. 4 CONTRAINDICATIONS SYMLIN is contraindicated in patients with any of the following: • serious hypersensitivity reaction to SYMLIN or to any of its product components. • hypoglycemia unawareness. • confirmed gastroparesis. • Prior serious hypersensitivity reaction to SYMLIN or its ingredients (4) • Hypoglycemia unawareness (4) • Confirmed gastroparesis (4)

Pregnancy

8.1 Pregnancy Risk Summary Available data from a small number of reports in the manufacturer’s safety database on SYMLIN use in pregnant women are not sufficient to determine a drug-associated risk for major birth defects, miscarriage, or other adverse maternal or fetal outcomes. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy ( see Clinical Considerations ). Ex-vivo studies using term perfused human, rabbit, and rat placentas indicate that SYMLIN has low potential to cross the maternal/fetal placental barrier.

Storage

Storage and Handling SYMLIN pen-injectors not in use: Refrigerate (2°C to 8°C; 36°F to 46°F), and protect from light. Do not freeze. Do not use if product has been frozen. Unused SYMLIN (opened or unopened) should not be used after the expiration (EXP) date printed on the carton and the label.
