🩺 Clinical
Octreotide immediate-release injection is used to decrease the amount of growth hormone (a natural substance) produced by people with acromegaly (condition in which the body produces too much growth hormone, causing enlargement of the hands, feet, and facial features; joint pain; and other symptoms) who cannot be treated with surgery, radiation, or another medication. Octreotide immediate-release injection is also used to control diarrhea and flushing caused by carcinoid tumors (slow-growing tumors that release natural substances that can cause symptoms) and vasoactive intestinal peptide secre...

🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE Octreotide acetate injection is a somatostatin analogue indicated: Acromegaly : To reduce blood levels of growth hormone (GH) and insulin growth factor-1 (IGF-1; somatomedin C) in acromegaly patients who have had inadequate response to or cannot be treated with surgical resection, pituitary irradiation, and bromocriptine mesylate at maximally tolerated doses. ( 1.1 ) Carcinoid Tumors : For the symptomatic treatment of patients with metastatic carcinoid tumors where it suppresses or inhibits the severe diarrhea and flushing episodes associated with the disease.
( 1.2 ) Vasoactive Intestinal Peptide Tumors (VIPomas) : For the treatment of profuse watery diarrhea associated with VIP-secreting tumors. ( 1.3 ) Limitations of Use Improvement in clinical signs and symptoms, or reduction in tumor size or rate of growth, were not shown in clinical trials performed with octreotide acetate injection; these trials were not optimally designed to detect such effects. ( 1.4 )
1.1Acromegaly Octreotide acetate injection is indicated to reduce blood levels of growth hormone (GH) and insulin growth factor-1 (IGF-1; somatomedin C) in acromegaly patients who have had inadequate response to or cannot be treated with surgical resection, pituitary irradiation, and bromocriptine mesylate at maximally tolerated doses.
1.2Carcinoid Tumors Octreotide acetate injection is indicated for treatment of severe diarrhea and flushing episodes associated with metastatic carcinoid tumors.
1.3Vasoactive Intestinal Peptide Tumors Octreotide acetate injection is indicated for the treatment of the profuse watery diarrhea associated with vasoactive intestinal peptide tumors (VIPomas)-secreting tumors.
1.4Important Limitations of Use Improvement in clinical signs and symptoms, or reduction in tumor size or rate of growth, were not shown in clinical trials performed with octreotide acetate injection; these trials were not optimally designed to detect such effects.
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Octreotide acetate injection may be administered subcutaneously or intravenously. ( 2.1 ) Acromegaly : Recommended initial octreotide acetate dosage is 50 mcg three times daily during the initial 2 weeks of therapy. Maintenance dose 100 mcg to 500 mcg three times daily.
( 2.2 ) Carcinoid Tumors : Recommended dosage range of 100 mcg to 600 mcg daily in two to four divided doses during the initial 2 weeks of therapy. ( 2.3 ) VIPomas : Recommended dosage range of 200 mcg to 300 mcg daily in two to four divided doses during the initial 2 weeks of therapy. ( 2.4 )
2.1Dosage and Administration Overview Octreotide acetate injection may be administered subcutaneously or intravenously. Pain with subcutaneous administration may be reduced by using the smallest volume that will deliver the desired dose. Sites should be rotated in a systematic manner.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. Do not use if particulates and/or discoloration are observed. Octreotide acetate injection is not compatible in Total Parenteral Nutrition solutions because of the formation of a glycosyl octreotide conjugate which may decrease the efficacy of the product.
Octreotide acetate injection may be diluted in volumes of 50 mL to 200 mL and infused intravenously over 15 to 30 minutes or administered by intravenous (IV) push over 3 minutes. In emergency situations (e.g., carcinoid crisis), it may be given by rapid bolus. Assess total and/or free T4 levels at baseline and periodically during chronic octreotide acetate therapy.
2.2Recommended Dosage and Monitoring for Acromegaly The recommended initial dosage of octreotide acetate is 50 mcg three times daily to be administered subcutaneously. Increase octreotide acetate dose based upon GH or IGF-1 levels. The goal is to achieve GH levels less than 5 ng/mL or IGF-1 levels within normal range.
Monitor GH or IGF-1 every two weeks after initiating octreotide acetate therapy or with dosage change, and to guide titration. The most common dosage is 100 mcg three times daily, but some patients require up to 500 mcg three times daily for maximum effectiveness. Doses greater than 300 mcg/day seldom result in additional biochemical benefit, and if an increase in dose fails to provide additional benefit, the dose should be reduced.
Octreotide acetate injection should be withdrawn yearly for approximately 4 weeks from patients who have received irradiation to assess disease activity. If GH or IGF-1 levels increase and signs and symptoms recur, octreotide acetate injection therapy may be resumed.
2.3Recommended Dosage and Monitoring for Carcinoid Tumors The recommended daily dosage of octreotide acetate injection during the first 2 weeks of therapy ranges from 100 to 600 mcg/day in two to four divided doses given subcutaneously (mean daily dosage is 300 mcg). In the clinical studies, the median daily maintenance dosage was approximately 450 mcg, but clinical and biochemical benefits were obtained in some patients with as little as 50 mcg, while others required doses up to 1500 mcg/day. However, experience with doses above 750 mcg/day is limited.
Measurement of urinary 5-hydroxyindole acetic acid, plasma serotonin, plasma Substance P may be useful in monitoring the progress of therapy.
2.4Recommended Dosage and Monitoring for Vasoactive Intestinal Peptide Tumors Daily dosages of 200 mcg to 300 mcg in two to four divided doses given subcutaneously are recommended during the initial 2 weeks of therapy (range, 150 mcg to 750 mcg) to control symptoms of the disease. On an individual basis, dosage may be adjusted to achieve a therapeutic response, but usually doses above 450 mcg/day are not required. Measurement of Plasma vasoactive intestinal peptide (VIP) may be useful in monitoring the progress of therapy.

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Cardiac Function Abnormalities : Increased risk for higher degree of atrioventricular blocks. Consider cardiac monitoring in patients receiving octreotide acetate injection intravenously. Bradycardia, arrhythmias, or conduction abnormalities may occur.
Use with caution in at-risk patients. Dosage adjustment of cardiac medications may be necessary. ( 5.1 ) Cholelithiasis and Complications of Cholelithiasis : Monitor periodically.
Discontinue if complications of cholelithiasis are suspected. ( 5.2 ) Glucose Metabolism : Hypoglycemia or hyperglycemia may occur. Glucose monitoring is recommended and anti-diabetic treatment may need adjustment.
( 5.3 ) Thyroid Function : Hypothyroidism may occur. Monitor thyroid levels periodically. ( 5.4 ) Steatorrhea and Malabsorption of Dietary Fats : New onset steatorrhea, stool discoloration, loose stools, abdominal bloating, and weight loss may occur.
If new occurrence or worsening of these symptoms are reported, evaluate for potential pancreatic exocrine insufficiency. ( 5.5 )
5.1Cardiac Function Abnormalities Complete Atrioventricular Block Patients who receive octreotide acetate injection intravenously may be at increased risk for higher degree atrioventricular blocks. In postmarketing reports, complete atrioventricular block was reported in patients receiving IV octreotide acetate injection during surgical procedures. In the majority of patients, octreotide acetate injection was given at higher than recommended doses and/or as a continuous IV infusion.
The safety of continuous IV infusion has not been established in patients receiving octreotide acetate injection for the approved indications. Consider cardiac monitoring in patients receiving octreotide acetate injection intravenously. Other Cardiac Conduction Abnormalities Other cardiac conduction abnormalities have occurred during treatment with octreotide acetate injection.
In acromegalic patients, bradycardia (< 50 bpm) developed in 25%; conduction abnormalities occurred in 10% and arrhythmias occurred in 9% of patients during octreotide acetate injection therapy [see Adverse Reactions (6) ] . Other electrocardiogram (ECG) changes observed included 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 (CHF), initiation of octreotide acetate injection therapy resulted in worsening of CHF with improvement when drug was discontinued. Confirmation of a drug effect was obtained with a positive rechallenge.
5.2Cholelithiasis and Complications of Cholelithiasis Octreotide acetate injection may inhibit gallbladder contractility and decrease bile secretion, which may lead to gallbladder abnormalities or sludge. Acute cholecystitis, ascending cholangitis, biliary obstruction, cholestatic hepatitis, or pancreatitis have been reported with octreotide acetate injection therapy. In clinical trials (primarily patients with acromegaly or psoriasis), the incidence of biliary tract abnormalities was 63% (27% gallstones, 24% sludge without stones, 12% biliary duct dilatation).
The incidence of stones or sludge in patients who received octreotide acetate injection for 12 months or longer was 52%. Less than 2% of patients treated with octreotide acetate injection for 1 month or less developed gallstones. One patient developed ascending cholangitis during octreotide acetate injection therapy and died.
If complications of cholelithiasis are suspected, discontinue octreotide acetate injection and treat appropriately.
5.3Hyperglycemia and Hypoglycemia Octreotide acetate injection alters the balance between the counter-regulatory hormones, insulin, glucagon and GH, which may result in hypoglycemia or hyperglycemia. The hypoglycemia or hyperglycemia which occur…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Complete Atrioventricular Block [see Warnings and Precautions ( 5.1 )] Cholelithiasis and Complications of Cholelithiasis [see Warnings and Precautions ( 5.2 )] Hyperglycemia and Hypoglycemia [see Warnings and Precautions ( 5.3 )] Thyroid Function Abnormalities [see Warnings and Precautions ( 5.4 )] Steatorrhea and Malabsorption of Dietary Fats [see Warnings and Precautions ( 5.5 ) Changes in Vitamin B 12 Levels [see Warnings and Precautions ( 5.6 )] Most common adverse reactions (incidence > 10%) in patients with acromegaly are gallbladder abnormalities, sinus bradycardia, diarrhea, loose stools, nausea, abdominal discomfort, hyperglycemia, and hypothyroidism.
In other patients, most common adverse reactions (incidence > 10%) are gallbladder abnormalities. ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact Gland Pharma Limited at 864-879-9994 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical Trials Experience 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. Gallbladder Abnormalities Gallbladder abnormalities, especially stones and/or biliary sludge, frequently develop in patients on chronic octreotide acetate injection therapy [see Warnings and Precautions (5.1) ] . In clinical trials (primarily patients with acromegaly or psoriasis), the incidence of biliary tract abnormalities was 63% (27% gallstones, 24% sludge without stones, 12% biliary duct dilatation).
The incidence of stones or sludge in patients who received octreotide acetate injection for 12 months or longer was 52%. Less than 2% of patients treated with octreotide acetate injection for 1 month or less developed gallstones. Cardiac In acromegalics, sinus bradycardia (< 50 bpm) developed in 25%; conduction abnormalities occurred in 10% and arrhythmias developed in 9% of patients during octreotide acetate injection therapy [see Warnings and Precautions (5.1) ] .
Gastrointestinal Diarrhea, loose stools, nausea, and abdominal discomfort were each seen in 34% to 61% of acromegalic patients in U.S. studies. 2.6% of the patients discontinued therapy due to these symptoms. These symptoms were seen in 5% to 10% of patients with carcinoid tumors and VIPomas.
The frequency of these symptoms was not dose related, but diarrhea and abdominal discomfort generally resolved more quickly in patients treated with 300 mcg/day than in those treated with 750 mcg/day. Vomiting, flatulence, abnormal stools, abdominal distention, and constipation were each seen in less than 10% of patients. In rare instances, gastrointestinal side effects may resemble acute intestinal obstruction, with progressive abdominal distension, severe epigastric pain, abdominal tenderness, and guarding.
Hypo/Hyperglycemia Hypoglycemia and hyperglycemia occurred in 3% and 16% of acromegalic patients, respectively, but only in about 1.5% of other patients. Symptoms of hypoglycemia were noted in approximately 2% of patients. Hypothyroidism In acromegalics, biochemical hypothyroidism alone occurred in 12% while goiter occurred in 8% and 4% required initiation of thyroid replacement therapy during octreotide acetate injection therapy [see Warnings and Precautions (5.4) ] .
In patients without acromegaly, hypothyroidism has only been reported in several isolated patients and goiter has not been reported. Other Adverse Events Pain on injection was reported in 7.7%, headache in 6%, and dizziness in 5%. Pancreatitis was also observed [see Warnings and Precautions (5.2) ] .
Other Adverse Events 1% to 4% Other events, each observed in 1% to 4% of patients, included fatigue, weakness, pruritus, joint pain, backache, urinary tract infection, cold symptoms, flu symptoms, injection site…
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS The following drugs require monitoring and possible dose adjustment when used with octreotide acetate injection : cyclosporine, insulin, oral hypoglycemic agents, beta-blockers, and bromocriptine. ( 7 ) Lutetium Lu 177 Dotatate Injection : Discontinue octreotide acetate injection at least 24 hours prior to each lutetium Lu 177 dotatate dose. ( 7.6 )
7.1Cyclosporine Octreotide has been associated with alterations in nutrient absorption, so it may have an effect on absorption of orally administered drugs. Concomitant administration of octreotide acetate injection with cyclosporine may decrease blood levels of cyclosporine and result in transplant rejection.
7.2Insulin and Oral Hypoglycemic Drugs Octreotide inhibits the secretion of insulin and glucagon. Therefore, blood glucose levels should be monitored when octreotide acetate injection treatment is initiated or when the dose is altered and anti-diabetic treatment should be adjusted accordingly.
7.3Bromocriptine Concomitant administration of octreotide and bromocriptine increases the availability of bromocriptine.
7.4Other Concomitant Drug Therapy Concomitant administration of bradycardia-inducing drugs (e.g., beta-blockers) may have an additive effect on the reduction of heart rate associated with octreotide. Dose adjustments of concomitant medication may be necessary. Octreotide has been associated with alterations in nutrient absorption, so it may have an effect on absorption of orally administered drugs.
7.5Drug Metabolism Interactions 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 GH. Since it cannot be excluded that octreotide may have this effect, other drugs mainly metabolized by CYP3A4 and which have a low therapeutic index (e.g., quinidine, terfenadine) should therefore be used with caution.
7.6Lutetium Lu 177 Dotatate Injection Octreotide competitively binds to somatostatin receptors and may interfere with the efficacy of lutetium Lu 177 dotatate. Discontinue octreotide acetate injection at least 24 hours prior to each lutetium Lu 177 dotatate dose.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Females and Males of Reproductive Potential : Advise premenopausal females of the potential for an unintended pregnancy. ( 8.3 )
8.1Pregnancy Risk Summary The limited data with octreotide acetate injection in pregnant women are insufficient to inform a drug-associated risk for major birth defects and miscarriage. In animal reproduction studies, no adverse developmental-effects were observed with IV administration of octreotide to pregnant rats and rabbits during organogenesis at doses 7- and 13-times, respectively the maximum recommended human dose (MRHD) of 1.5 mg/day based on body surface area (BSA). Transient growth retardation, with no impact on postnatal development, was observed in rat offspring from a pre- and post-natal study of octreotide at IV doses below the MRHD based on BSA (see Data) .
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Human Data In postmarketing data, a limited number of exposed pregnancies have been reported in patients with acromegaly.
Most women were exposed to octreotide during the first trimester of pregnancy at doses ranging from 100 to 300 mcg/day of octreotide acetate injection or 20 mg to 30 mg once a month of octreotide acetate for injectable suspension, however some women elected to continue octreotide therapy throughout pregnancy. In cases with a known outcome, no congenital malformations were reported. Animal Data In embryo-fetal development studies in rats and rabbits, pregnant animals received IV doses of octreotide up to 1 mg/kg/day during the period of organogenesis.
A slight reduction in body weight gain was noted in pregnant rats at 0.1 and 1 mg/kg/day. There were no maternal effects in rabbits or embryo-fetal effects in either species up to the maximum dose tested. At 1 mg/kg/day in rats and rabbits, the dose multiple was approximately 7- and 13-times, respectively, at the highest recommended human dose of 1.5 mg/day based on BSA.
In a pre- and post-natal development rat study at IV doses of 0.02 to 1 mg/kg/day, a transient growth retardation of the offspring was observed at all doses which was possibly a consequence of GH inhibition by octreotide. The doses attributed to the delayed growth are below the human dose of 1.5 mg/day, based on BSA.
8.2Lactation Risk Summary There is no information available on the presence of octreotide acetate injection in human milk, the effects of the drug on the breastfed infant, or the effects of the drug on milk production. Studies show that octreotide administered subcutaneously passes into the milk of lactating rats; however, due to species-specific differences in lactation physiology, animal data may not reliably predict drug levels in human milk ( see Data ). The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for octreotide acetate injection, and any potential adverse effects on the breastfed child from octreotide acetate injection or from the underlying maternal condition.
Data Following a subcutaneous dose (1 mg/kg) of octreotide to lactating rats, transfer of octreotide into milk was observed at a low concentration compared to plasma (milk/plasma ratio of 0.009).
8.3Females and Males of Reproductive Potential Discuss the potential for unintended pregnancy with premenopausal women as the therapeutic benefits of a reduction in GH levels and normalization of insulin-like growth factor 1 (IGF-1) concentration in acromegalic females treated with octreotide may lead to improved fertility.

🧒 Pediatric Use ▾
8.4Pediatric Use Safety and efficacy of octreotide acetate injection in the pediatric population have not been demonstrated. No formal controlled clinical trials have been performed to evaluate the safety and effectiveness of octreotide acetate injection in pediatric patients under age 6 years. In postmarketing reports, serious adverse events, including hypoxia, necrotizing enterocolitis, and death, have been reported with octreotide acetate injection use in children, most notably in children under 2 years of age.
The relationship of these events to octreotide has not been established as the majority of these pediatric patients had serious underlying co-morbid conditions. The efficacy and safety of octreotide acetate injection using the octreotide acetate for injectable suspension formulation was examined in a single randomized, double-blind, placebo-controlled, 6 month pharmacokinetics study in 60 pediatric patients age 6 to 17 years with hypothalamic obesity resulting from cranial insult. The mean octreotide concentration after 6 doses of 40 mg octreotide acetate for injectable suspension administered by intramuscular (IM) injection every 4 weeks was approximately 3 ng/mL.
Steady-state concentrations was achieved after 3 injections of a 40-mg dose. Mean body mass index (BMI) increased 0.1 kg/m 2 in octreotide acetate for injectable suspension-treated subjects compared to 0.0 kg/m 2 in saline control-treated subjects. Efficacy was not demonstrated.
Diarrhea occurred in 11 of 30 (37%) patients treated with octreotide acetate for injectable suspension. No unexpected adverse events were observed. However, with octreotide acetate for injectable suspension at 40 mg once a month, the incidence of new cholelithiasis in this pediatric population (33%) was higher than that seen in other adult indications such as acromegaly (22%) or malignant carcinoid syndrome (24%), where octreotide acetate for injectable suspension was 10 mg to 30 mg once a month.
🧓 Geriatric Use ▾
8.5Geriatric Use Clinical studies of octreotide acetate injection did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
🆘 Overdosage ▾
10 OVERDOSAGE A limited number of accidental overdoses of octreotide acetate injection in adults have been reported. In adults, the doses ranged from 2,400 to 6,000 mcg/day administered by continuous infusion (100 to 250 mcg/hour) or subcutaneously (1,500 mcg 3 times a day). Adverse events in some patients included arrhythmia, complete atrioventricular block, hypotension, cardiac arrest, brain hypoxia, pancreatitis, hepatitis steatosis, hepatomegaly, lactic acidosis, flushing, diarrhea, lethargy, weakness, and weight loss.
If overdose occurs, symptomatic management is indicated. Up-to-date information about the treatment of overdose can often be obtained from the National Poison Control Center at 1-800-222-1222.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Octreotide acetate injection exerts pharmacologic actions similar to the natural hormone, somatostatin. It is an even more potent inhibitor of GH, glucagon, and insulin than somatostatin. Like somatostatin, it also suppresses luteinizing hormone (LH) response to gonadotropin releasing hormone (GnRH), decreases splanchnic blood flow, and inhibits release of serotonin, gastrin, VIP, secretin, motilin, and pancreatic polypeptide.
By virtue of these pharmacological actions, octreotide has been used to treat the symptoms associated with metastatic carcinoid tumors (flushing and diarrhea), and VIP secreting adenomas (watery diarrhea).
12.2Pharmacodynamics Octreotide substantially reduces GH and/or IGF-1 (somatomedin C) levels in patients with acromegaly. Single doses of octreotide have been shown to inhibit gallbladder contractility and to decrease bile secretion in normal volunteers. In controlled clinical trials, the incidence of gallstone or biliary sludge formation was markedly increased [see Warnings and Precautions (5.2) ] . Octreotide suppresses secretion of TSH.
12.3Pharmacokinetics Absorption After subcutaneous injection, octreotide is absorbed rapidly and completely from the injection site. Peak concentrations of 5.2 ng/mL (100-mcg dose) were reached 0.4 hours after dosing. Using a specific radioimmunoassay, IV and subcutaneous doses were found to be bioequivalent.
Peak concentrations and area under the curve (AUC) values were dose proportional after IV single doses up to 200 mcg and subcutaneous single doses up to 500 mcg and after subcutaneous multiple doses up to 500 mcg 3 times a day (1,500 mcg/day). In patients with acromegaly, a mean peak concentration of 2.8 ng/mL (100-mcg dose) was reached in 0.7 hours after subcutaneous dosing. Distribution In healthy volunteers, the distribution of octreotide from plasma was rapid (tα½ = 0.2 h), the volume of distribution (Vdss) was estimated to be
13.6L, and the total body clearance ranged from 7 L/hr to 10 L/hr. In blood, the distribution into the erythrocytes was found to be negligible and about 65% was bound in the plasma in a concentration-independent manner. Binding was mainly to lipoprotein and, to a lesser extent, to albumin. In patients with acromegaly, the volume of distribution (Vdss) was estimated to be 21.6 ±
8.5L, and the total body clearance was increased to 18 L/h. The mean percent of the drug bound was 41.2%. Elimination The elimination of octreotide from plasma had an apparent half-life of 1.7 to 1.9 hours compared with 1 to 3 minutes with the natural hormone.
The duration of action of octreotide acetate injection is variable but extends up to 12 hours depending upon the type of tumor. About 32% of the dose is excreted unchanged into the urine. In an elderly population, dose adjustments may be necessary due to a significant increase in the half-life (46%) and a significant decrease in the clearance (26%) of the drug.
In patients with acromegaly, the disposition and elimination half-lives were similar to normal subjects. Specific Populations Renal Impairment In patients with mild renal impairment (CL CR 40 to 60 mL/min), octreotide t 1/2 was 2.4 hours and total body clearance was
8.8L/hr, in moderate impairment (CL CR 10 to 39 mL/min) t 1/2 was 3.0 hours and total body clearance
7.3L/hr. In patients with severe renal impairment not requiring dialysis (CL CR < 10 mL/min), octreotide t 1/2 was 3.1 hours and total body clearance was
7.6L/hr. In patients with severe renal failure requiring dialysis, total body clearance was reduced to about half that found in healthy subjects (from approximately 10 L/hr to
4.5L/hr). Hepatic Impairment Patients with liver cirrhosis showed prolonged elimination of drug, with octreotide t 1/2 increasing to 3.7 hr and total body clearance decreasing to
5.9L/hr, whereas patients with fatty liver disease showed t 1/2 increased to 3.4 hr and total body clearance of
8.2L/hr.

🧬 Mechanism of Action ▾
12.1Mechanism of Action Octreotide acetate injection exerts pharmacologic actions similar to the natural hormone, somatostatin. It is an even more potent inhibitor of GH, glucagon, and insulin than somatostatin. Like somatostatin, it also suppresses luteinizing hormone (LH) response to gonadotropin releasing hormone (GnRH), decreases splanchnic blood flow, and inhibits release of serotonin, gastrin, VIP, secretin, motilin, and pancreatic polypeptide.
By virtue of these pharmacological actions, octreotide has been used to treat the symptoms associated with metastatic carcinoid tumors (flushing and diarrhea), and VIP secreting adenomas (watery diarrhea).
