OMEGAVEN Emulsion for injection Ref.[27455] Active ingredients: Omega-3-acid ethyl esters

Omegaven (fish oil triglycerides) is a sterile, nonpyrogenic, white, homogenous emulsion for intravenous infusion as a supply of calories in patients with PNAC. Each mL of Omegaven contains 0.1 g of fish oil, 0.012 g egg phospholipids, 0.025 g glycerin, 0.15 to 0.3 mg dl-alpha-tocopherol, 0.3 mg sodium oleate, water for injection, and sodium hydroxide for pH adjustment (pH 6 to 9). The phosphate content is 0.015 mmol/mL.

The fish oil included in Omegaven is a triglyceride mixture consisting of esters of long-chain saturated fatty acids and unsaturated fatty acids with the following structure:

where , , and are long chain acyl groups. Because triglycerides often contain different long chain fatty acids at each position, possible structures can have molecular weights ranging from 700 to 1000 g/mol. The main fatty acid components of the fish oil in Omegaven are EPA (13% to 26%) and DHA (14% to 27%). The fish oil also contains palmitic acid (4% to 12%), oleic acid (4% to 11%), palmitoleic acid (4% to 10%), myristic acid (2% to 7%), and arachidonic acid (0.2% to 2.0%). Additionally, the mean contents of linoleic acid and alpha-linolenic acid are 1.5% and 1.1%, respectively. The fish oil component has a total omega-3 fatty acid content of 40% to 54%. The empirical formula, molecular weight, and chemical structure of the main fatty acid components are:

Omegaven 5 g/50 mL contains 5 grams of fish oil and 0.6 g egg phospholipids, 1.25 g glycerin, 7.5 to 15 mg dl-alpha-tocopherol, 0.015 g sodium oleate, water for injection, and sodium hydroxide for pH adjustment (pH 6 to 9) packaged in a single-dose 50-mL glass bottle enclosed with a rubber stopper. The phosphate content of the drug product is 0.75 mmol.

The mean content of the two major fatty acid components in 50 mL are 1.0 g EPA (range: 0.6 to 1.5 g) and 0.96 g DHA (range: 0.7 to 1.7 g). Additionally, the mean content of linoleic acid, alpha-linolenic acid, and arachidonic acid per 50 mL are 0.16 g, 0.07 g, and 0.13 g, respectively.

Omegaven 10 g/100 mL contains 10 grams of fish oil and 1.2 g egg phospholipids, 2.5 g glycerin, 15 to 30 mg dl-alpha-tocopherol, 0.03 g sodium oleate, water for injection, and sodium hydroxide for pH adjustment (pH 6 to 9) packaged in a single-dose 100-mL glass bottle enclosed with rubber stopper. The phosphate content of the drug product is 1.5 mmol. The mean content of the two major fatty acid components in 100 mL are 2.0 g EPA (range: 1.2 to 3.0 g) and 1.9 g DHA (range: 1.3 to 3.3 g). Additionally, the mean content of linoleic acid, alpha-linolenic acid, and arachidonic acid per 100 mL are 0.31g, 0.13 g, and 0.25 g; respectively.

The total energy content of Omegaven is 112 kcal/100 mL (1.12 kcal/mL), including lipids, phospholipids, and glycerol.

Omegaven has an osmolality of approximately 342 mOsm/kg water (which represents an osmolarity of 273 mOsm/L).

Omegaven contains no more than 25 mcg/L of aluminum.
