The following dosing information is available for SANDOSTATIN (octreotide acetate):
Dosage of octreotide acetate is expressed in terms of octreotide.
Octreotide acetate is administered by the subcutaneous, IV, IM, or oral route depending on the specific use. Octreotide immediate-release injection is administered by subcutaneous injection orby IV injection or infusion for symptom control in patients with acromegaly, carcinoid tumors, or vasoactive intestinal peptide (VIP) tumors. Subcutaneous injection is the usual route of administration; IV administration generally is reserved for emergency situations (e.g., acute management of carcinoid crisis) that require rapid injection.
Octreotide is also available as a long-acting release (LAR) suspensionfor IM administration in patients with acromegaly, carcinoid tumors, or VIP-secreting tumors who have responded to and tolerated the immediate-release injection. Octreotide LAR suspension shouldnot be administered subcutaneously or IV. The LARinjectablesuspension may be used after tolerance has been established with at least 2 weeks of subcutaneous therapy with immediate-release octreotide. Octreotide is also available as delayed-release capsules for the long-term maintenance treatment of acromegaly in patients who have responded to and tolerated treatment with octreotide or lanreotide.

There are 3 moderate interactions.
The clinician should assess the patient’s characteristics and take action as needed. Actions required for moderate interactions include, but are not limited to, discontinuing one or both agents, adjusting dosage, altering administration.
| Drug Interaction | Drug Names |
|---|---|
| Cyclosporine/Octreotide SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Octreotide may interfere with the enterohepatic circulation of cyclosporine or may delay or inhibit the absorption of cyclosporine.(2) CLINICAL EFFECTS: The concurrent administration of octreotide and cyclosporine may result in a decrease in cyclosporine levels. PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: Cyclosporine levels should be monitored in patients receiving concurrent therapy with cyclosporine and octreotide. The dosage of cyclosporine may need to be adjusted if octreotide is added to or discontinued from cyclosporine therapy. Octreotide may need to be discontinued. DISCUSSION: In a study, 23 of 65 pancreas transplant patients were treated octreotide. During octreotide therapy, the dosage of oral cyclosporine required to maintain therapeutic levels increased. In addition 15 patients required supplemental intravenous cyclosporine to maintain cyclosporine levels.(2) In a case report, a cadaver renal and whole-pancreas transplant recipient was treated for a fistula with octreotide. Cyclosporine blood levels slowly decreased despite an increase in cyclosporine dosage (from 180 mg to 300 mg daily). When the cyclosporine level decreased below 100 ng/ml, intravenous cyclosporine was administered. Octreotide was discontinued when the patient developed graft rejection. Cyclosporine levels returned to baseline and the rejection was reversed.(1) In another case report, cyclosporine levels dropped below detection when octreotide was added to his therapy. The patient was successfully treated for graft rejection and octreotide was discontinued.(3) These authors reported a total of nine patients in whom cyclosporine levels decreased following the addition of octreotide to cyclosporine.(4) In a study of 10 patients with severe diarrhea following bone marrow transplantation, cyclosporine dosage requirements increased by 50% in two subjects following the addition of octreotide.(5) |
CYCLOSPORINE, CYCLOSPORINE MODIFIED, GENGRAF, NEORAL, SANDIMMUNE |
| Pegvisomant/Somatostatin Analogues SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: The exact mechanism is unknown. CLINICAL EFFECTS: Concurrent use may result in an increased risk of hepatotoxicity.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The Canadian manufacturer of pegvisomant states that the concurrent use of pegvisomant and somatostatin analogues may lead to markedly increase hepatic enzymes in patients treated with this combination.(1) DISCUSSION: Based on post marketing studies, there was marked hepatic elevations (greater than 10 times the upper limit of normal (ULN) which was reported in 3 out of 26 patients treated with the combination of pegvisomant and octreotide. The ranges for the elevations for ALT and AST ranged from 13 to 45 times the ULN within three months of treatment. All three patients recovered after discontinuation of treatment.(1) |
SOMAVERT |
| Telotristat/Octreotide (Short-Acting) SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Short-acting octreotide may decrease the absorption of telotristat.(1) CLINICAL EFFECTS: Concurrent administration of short-acting octreotide significantly decreases systemic exposure of telotristat.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: When used in combination, administer short-acting octreotide at least 30 minutes after telotristat.(1) DISCUSSION: Concurrent administration of short-acting octreotide (200 mcg), decreased the maximum concentration (Cmax) of telotristat ethyl and telotristat by 86% and 79%, respectively. The area-under-curve (AUC) of telotristat ethyl and telotristat were decreased by 81% and 68%, respectively.(1) |

The following precautions are available for SANDOSTATIN (octreotide acetate):
Safety and efficacy of octreotide immediate-release injection, long-acting release (LAR) injectable suspension, and the oral preparation have not been established in pediatric patients. Controlled clinical trials to evaluate the safety and effectiveness of octreotide injection in pediatric patientsyounger than 6 years of age have not been performed. In postmarketing reports, serious adverse events, including hypoxia, necrotizing enterocolitis, and death, have been reported with octreotide use in children, most notably in children under 2 years of age.
The majority of these pediatric patients had serious underlying co-morbid conditions and the relationship of such adverse events to octreotide has not been established. Octreotide LARinjectable suspension (40 mg once monthly) has been investigated in a randomized, placebo-controlled study in pediatric patients 6-17 years of age withhypothalamic obesity secondary to cranial insult+. Efficacy was not demonstrated and treatment with octreotide was not associated with unexpected adverse events; however, new cholelithiasis was reported in 33% of children receiving octreotide.

There are no adequate and controlled studies of octreotide in pregnant women, and the drug should be used during pregnancy only when clearly needed. In cases with a known outcome, no congenital malformations have been reported among patients with acromegaly exposed to octreotide during the first trimester, including women electing to continue the drug throughout pregnancy. The women were exposed to 100-300 mcg/day of octreotide immediate-release or 20-30 mg once a month of octreotide LAR suspension.
Animal reproduction studies conducted with octreotide at doses up to 16 times the highest recommended human dose based on body surface area (BSA) have not revealed evidence of harm to the fetus. Transient growth retardation of rat offspring was observed atIV octreotide doses of 0.02-1 mg/kg per day which are below the maximum recommended human dose of 1.5mg/day,
based on body surface area; this is possibly a consequence of growth hormone inhibition by octreotide. There are insufficient data with octreotide LAR suspension in pregnant womento inform drug-associated-risk for major birth defects and miscarriage.

Octreotide is present in rat milk following subcutaneous injection;however, there is no information regarding the presence of octreotide in human milk. Consider the benefits of breast-feeding and the importance of octreotide to the woman along with potential adverse effects on the breast-fed infant from the drug or underlying maternal condition.
Clinical trials of octreotide did not include sufficient numbers of patients 65 years of age or older to determine whether such patients respond differently than younger patients. In a small number of patients 65 years of age or older treated with the oral preparation (Mycapssa(R)), no overall differences in safety or effectiveness were observed between these patients and younger patients. Other reported clinical experience has not identified differences in response between geriatric patients and younger adults, but greater sensitivity of some older individuals cannot be ruled out.
Half-life increased by 46% andclearance decreasedby 26% following administration of immediate-release octreotide injection in an elderly population. Dosage of octreotide should be selected with caution and generally initiated at the lower end of the dosing range because of age-related decreases in hepatic, renal, and/or cardiac function and concomitant disease and drug therapy.
