| Description | A diagnostic radiopharmaceutical containing iodinated I 131 albumin for intravenous imaging. Following Intravenous infusion, radioiodinated albumin human is uniformly distributed throughout the intravascular pool within 10 minutes; extravascular distribution takes place more slowly (2 days). Indicated for use in determinations of total blood and plasma volumes, cardiac output, cardiac and pulmonary blood volumes and circulation times |
| Indication/Disease | For determination of total blood and plasma volumes |
| Pharmacodynamics | Regulates the colloidal osmotic pressure of blood. It is used to increase the circulating plasma volume, thereby reducing hemoconcentrtion and blood viscosity. Also used as a transport protein that binds naturally occurring, therapeutic and toxic materials in circulation. |
| Mechanism of Action | Serum albumin acts as a high molecular weight, very soluble osmolyte |
| Toxicity | In general, human albumin solutions are well-tolerated and no specific, clinically relevant alterations in organ function or coagulopathy have been substantiated. The most common adverse reactions are rigors, hypotension, tachycardia with increased heart rate, fever, chills, nausea, vomiting, dyspnea and/or bronchospasm, skin rash/pruritus. Stop the infusion immediately if anaphylaxis, with or without shock is observed. Hypervolemia may occur if the dosage and rate of infusion are not adjusted to the volume status of the patient. When clinical signs of cardiovascular overload occur (headache, dyspnea, jugular venous distention, increased blood pressure), the infusion must be slowed or stopped immediately. |

| Absorption | NA |
| Albumin is distributed throughout the extracellular space and more than 60% of the body albumin pool is located in the extravascular fluid space . In healthy adults, less than 10% of infused albumin leaves the intravascular compartment during the first 2 hours following infusion of albumin. There is considerable individual variation in the effect of albumin on plasma volume, however. In some patients, the plasma volume can remain elevated for several hours. In critically ill patients, however, albumin can leak out of the vascular space in substantial amounts at an unpredictable rate that is difficult to predict. |

| Prescribed For | Jeanotope I-125 is indicated for use in the determination of total blood and plasma volume. |
| Chemical Name | NA |
| Formulation | Each milliliter provides approximately 10 mg protein (normal human serum albumin), 1.6 mg sodium phosphate, 16 mg sodium biphosphate, not more than 0.4 mg guanidine hydrochloride, sodium chloride for isotonicity, and 9 mg benzyl alcohol as a preservative. The stabilizer aceryltryptophanate and sodium caprylate have a concentration of less, than 0.0089M. |
| Physical Appearance | Jeanatope 1-125 (Iodinated 1-125 Albumin Injection) is a Sterile, nonpyrogenic, aqueos solution |
| Route of Administration | Intravenous infusion |
| Recommended Dosage | When a procedure such as a blood volume determination is to be repeated, the total dosage administered in any one week should not exceed 7.4 megabecquerels, (200 microcuries). |
| Contraindication | At present there are no known contraindications to the use of this preparation |
| Side Effects | Although the immunological properties of albumin human are believed to be virtually unaltered by the iodination process, there is a theoretical possibility that allergic reactions may occur in patients receiving additional doses a number of weeks after an initial dose. |
