Abstract

PURPOSE:The titled composition containing at least one selected from essential fatty acids, metal salts, lower alkyl esters mono-, di- and triglycerides thereof as an active constituent. CONSTITUTION:A rectal administration composition, containing at least one selected from essential fatty acids, e.g. linolic acid, metal salts thereof, e.g. an alkali metal or alkaline earth metal salt, lower alkyl esters thereof and mono-, di- and triglycerides thereof as an active constituent, and safely and easily administrable. Polyoxyl 40 stearate, polysorbate 80, sodium lauryl sulfate, etc. may be cited as a surfactant as an additive component in medicines. Anal suppository, soft capsule, etc. may be cited as the dosage form. A vegetable fat or oil, e.g. peanut oil, olive oil or corn oil, and a mineral oil, e.g. vaseline, may be cited as the oily base.

In recent years, high-calorie infusion methods have been used for nutritional management before and after surgery. High-calorie infusions are hypertonic solutions containing large amounts of glucose and amino acids, and are applied into central veins where blood flow is high. Unlike peripheral administration, it can be administered continuously without causing blood clot formation, and sufficient calories are supplied without causing water overload. Therefore, its clinical use has been remarkable, with reductions in mortality rates for upper gastrointestinal disorders and gastrointestinal suture failure, and high survival rates for patients with acute pancreatitis, and its indications are also being expanded. In particular, he has made significant contributions in the fields of gastrointestinal surgery and pediatric surgery.

However, high-calorie infusions containing glucose as a main component are nutritional methods that are quite different from daily eating habits, and therefore, potential metabolic abnormalities occur that result in non-physiological nutritional methods.

When fat-free, high-calorie infusions are administered, serum fatty acid composition shows a pattern of essential fatty acid deficiency within 2 to 4 weeks. In other words, the fraction of essential fatty acids such as linoleic acid and arachidonic acid decreases, and the fraction of palmitic acid and oleic acid produced from carbohydrates in the body increases. Furthermore, the amount of eicosatrienoic acid fraction derived from oleic acid, which is hardly observed under normal conditions, increases. Typical symptoms of essential fatty acid deficiency, such as skin rash, are rarely seen with actual high-calorie infusions, and even if they occur, they are not immediately life-threatening. However, essential fatty acid deficiencies are particularly likely to occur in children, and fat administration is necessary as a calorie source for neonatal development and to normalize fat metabolism during high-calorie infusions.

Therefore, currently, fat emulsions are used in conjunction with high-calorie infusions and administered peripherally. The fat emulsion is based on a combination of soybean oil and lecithin, and linoleic acid accounts for 50% of the fatty acid composition. With the combined use of fat emulsion, serum fatty acid composition does not show the pattern seen in essential fatty acid deficiency.

However, fat emulsions cannot be administered at home because they must be administered through a different route (peripherally) than high-calorie infusions. Therefore, it is desired to develop a fat preparation that can be administered safely and easily.
