Acromegaly
Reduction of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) [somatomedin C] in adults with acromegaly who have had inadequate response to or cannot be treated with surgical resection, pituitary irradiation, and bromocriptine mesylate at maximally tolerated doses
Bynfezia Pen
- 50 mcg SC TID initially
- Usual dose: 100 mcg SC TID; some patients require up to 500 mcg TID
- Doses >300 mcg/day seldom result in additional benefit; if an increase in dose fails to provide additional benefit, reduce dosage
-
Dosing titration
- Measure IGF-I levels q2Weeks after initiation or dosage change
- Alternatively, measuring growth hormone levels at 1-4 hr intervals for 8-12 hr after administration; goal is to achieve growth hormone levels <5 ng/mL or IGF-I levels within normal reference ranges for age and sex
- Once biochemical normalization, or maximal benefit is achieved, re-evaluate IGF-I or growth hormone levels at 6-month intervals

Warnings
Contraindications
Hypersensitivity
Cautions
Use caution in patients with hepatic impairment; patients with established cirrhosis may necessitate dosage adjustment
Use caution in patients with renal impairment; patients receiving dialysis may necessitate dosage adjustment; in patients with severe renal failure requiring dialysis, the half-life of the drug may be increased, necessitating adjustment of maintenance dosage
May alter fat absorption in some patients (monitor for pancreatitis)
Monitor for cholelithiasis; may impair gallbladder function; incidence of gallbladder stone or biliary sludge increases with duration of therapy exceeding 12 months; prophylactic cholecystectomy recommended if octreotide treatment is planned in in patients with gastrointestinal or pancreatic neuroendocrine tumors
There have been postmarketing reports of cholelithiasis (gallstones) resulting in complications requiring cholecystectomy; if complications of cholelithiasis are suspected, discontinue drug and treat appropriately
Depressed vitamin B12 levels and abnormal Schilling’s tests reported in some patients receiving therapy; monitoring of vitamin B12 levels is recommended during chronic therapy
Monitor for hypothyroidism (octreotide suppresses secretion of TSH); baseline and periodic assessment of thyroid function (TSH, total, and/or free T4) recommended during chronic therapy
Therapy may alter absorption of dietary fats in some patients
Use caution when giving drug to patients with cardiovascular disease
May enhance toxicity of QTc-prolonging agents
Use caution in patients with heart failure or concomitant medications that may alter heart rate or rhythm; arrhythmia, conduction abnormalities, and bradycardia reported in acromegalic and carcinoid syndrome patients; cardiovascular medications requirements may change
Depot formulation, not for treatment of sulfonylurea-induced hypoglycemia
Somatostatin analogs may affect glucose regulation; severe hypoglycemia may occur in type 1 diabetes patients; hyperglycemia may occur in type 2 diabetes or patients without diabetes; therapy may worsen hypoglycemia in patients with insulinomas; use with caution; glucose tolerance and anti- diabetic treatment should be periodically monitored during therapy
Dosage adjustments may be necessary in the elderly
Females of childbearing age should use adequate contraception because the treatment may restore fertility
In patients maintained on total parenteral nutrition (TPN), monitoring for elevations in zinc levels recommended
May reduce excessive fluid loss in patients with conditions that cause fluid losses
Although acromegaly may lead to infertility, there are reports of pregnancy in acromegalic women; in women with active acromegaly who have been unable to become pregnant, normalization of GH and IGF-1 (somatomedin C) may restore fertility; female patients of childbearing potential should be advised to use adequate contraception during treatment
Cardiac abnormalities
- Bradycardia and arrhythmia may occur; electrocardiogram (ECG) changes observed include QT prolongation, axis shifts, early repolarization, low voltage, R/S transition, and early R-wave progression; these ECG changes are not uncommon in acromegalic patients
- Dose adjustments in drugs such as beta-blockers that have bradycardia effects may be necessary
- In one acromegalic patient with severe congestive heart failure, initiation of herapy resulted in worsening of congestive heart failure with improvement when drug was discontinued
-
Complete atrioventricular block
- Patients who receive Injection intravenously may be at increased risk for higher degree atrioventricular blocks; the safety of continuous intravenous infusion has not been established in patients receiving the drug for the approved indications; consider cardiac monitoring in patients receiving the drug intravenously
Drug interaction overview
- Coadministration with cyclosporine may decrease blood levels of cyclosporine and result in transplant rejection
- Octreotide inhibits the secretion of insulin and glucagon; monitor blood glucose levels upon initiation or dose adjustment; patients with diabetes mellitus may require dose adjustments of insulin or other antidiabetic agents
- Coadministration with bromocriptine increases the availability of bromocriptine
- Patients receiving beta blockers, calcium channel blockers, or agents to control fluid and electrolyte balance, may require dose adjustments of these therapeutic agents
- Octreotide has been associated with alterations in nutrient absorption, so it may have an effect on absorption of orally administered drugs
- Limited published data indicate that somatostatin analogs might decrease the metabolic clearance of compounds known to be metabolized by cytochrome P450 enzymes, which may be due to the suppression of growth hormones
Pregnancy & Lactation
Pregnancy
Limited data in pregnant women are insufficient to inform a drug-associated risk for major birth defects and miscarriage
Reproductive potential
- Discuss potential for unintended pregnancy with premenopausal women as therapeutic benefits of a reduction in growth hormone (GH) levels and normalization of insulin-like growth factor 1 (IGF-1) concentration in acromegalic females treated with drug may lead to improved fertility
Animal data
- In animal reproduction studies, no-adverse- developmental-effects were observed with intravenous administration of drug to pregnant rats and rabbits during organogenesis at doses 7 and 13-times, respectively the maximum recommended human dose (MRHD) of 1500 mcg/day based on body surface area
- Transient growth retardation, with no impact on postnatal development, was observed in rat offspring from a pre- and post-natal study of octreotide at intravenous doses below the MRHD based on body surface area
Lactation
There is no information available on presence of drug in human milk, effects on breastfed infant, or on milk production; studies show that drug administered subcutaneously passes into milk of lactating rats
Consider developmental and health benefits of breastfeeding along with mother’s clinical need for therapy and any potential adverse effects on breastfed child from drug or from underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Somatostatin analog; decreases GH secretion, secretion of gastrin, VIP, glucagon, secretin, serotonin release and pancreatic polypeptide; in acromegaly, octreotide decreases growth hormone and IGF-1 secretion; suppresses LH response to GnRH secretion and decreases splanchnic blood flow
Absorption
Absorption rapid and complete (SC)
Bioavailability: SC, 100%; IM, 60%
Peak plasma time: IV, immediately after injection; SC, 15-30 min; PO, 90-120 min; IM, 60 min

OCTREOTIDE - INJECTION
(ok-TREE-oh-tide)
COMMON BRAND NAME(S): Sandostatin
USES: Octreotide is used to treat severe watery diarrhea and sudden reddening of the face and neck caused by certain types of tumors (such as carcinoid tumors, vasoactive intestinal peptide tumors) that are found usually in the intestines and pancreas. The symptoms occur when these tumors make too much of certain natural substances (hormones). This medication works by blocking the production of these hormones. By decreasing watery diarrhea, octreotide helps to reduce the loss of body fluids and minerals.Octreotide is also used to treat a certain condition (acromegaly) that occurs when the body makes too much of a certain natural substance called growth hormone. Treating acromegaly helps reduce the risk of serious problems such as diabetes and heart disease. Octreotide works by decreasing the amount of growth hormone to normal levels.This drug is not a cure for these conditions. This medication is usually used with other treatment (such as surgery, radiation, other drugs).
HOW TO USE: This medication is usually given by injection under the skin, usually 2 to 3 times a day or as directed by your doctor. Depending on your condition, it may be given by injection into a vein by a health care professional.If your doctor directs you to inject this medication under the skin yourself, learn all preparation and usage instructions from your health care professional. Learn how to store and discard needles and medical supplies safely. If you have questions, ask your health care professional.Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Before injecting each dose, clean the injection site with rubbing alcohol. Change the location of the injection site each time to avoid problem areas under the skin.Dosage is based on your medical condition and response to treatment.Use this medication regularly to get the most benefit from it. To help you remember, use it at the same times each day.Tell your doctor if your condition does not improve or if it worsens.
SIDE EFFECTS: Nausea, vomiting, loose/oily stools, constipation, stomach upset, gas, bloating, dizziness, or headache may occur. Pain and irritation at the injection site may also occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects.
