Definitions
- the present invention is directed to the improvement of the physical stability of long-term stored products for parenteral use and especially those products comprising a fatty emulsion packaged in at least partially oxygen permeable containers.
- Creaming or cream formation is often formed during storage fat emulsion and appears as a cream-like layer on top of the emulsion.
- the phenomenon is to a certain extent reversible when shaking the container with stored emulsion.
- Flocculation appears when drops in an emulsion is added to each other and coalescence appears when the drops float together and exchange phospholipids, leading to a break-up of the emulsion.
- Flocculation and coalescence are irreversible phenomena.
- Creaming is a technical problem for manufacturers of preparations for parenteral nutrition containing fatty emulsions and many attempts have been made overcome it, for example by adding stabilizing components, see EP 0220 152 ( page 2, lines 26 to 34).
- the creaming phenomenon appears due to reversed sedimentation of the fat droplets which is a normal process in emulsions.
- creaming can cause serious complications in parenteral nutrition, because it may lead to an irregular lipid supply during the administration, which in certain cases may cause hazardous aggregations of lipid particles in the blood system.
- the clinical problems with creaming and fat emulsions which are unstable in-vivo are previously disclosed in, for example, EP 0220152 (page 2, lines 34 to 55) and Clin Nutr, 1984, 3 (2), p 93-7.
- Helium has previously been suggested as a substitute for nitrogen gas in the packaging of sensitive surgical articles as disclosed in GB 1263217 or infusion fluids comprising fat emulsions EP 0510687 (page 7, lines 3 to 5). These documents suggests helium as an alternative inert gas for providing a substantially oxygen-free atmosphere for avoiding chemical degradation in terms of oxidation. However, it has not been previously disclosed that helium in any manner can lead to an improvement also in the physical stability of parenteral products comprising a fat emulsion.
- the aim of the present invention is to improve the physical stability of a stored product.
- An especially favoured object of the invention is to improve storage of pre-packaged products for parenteral administration, which both are sensitive for air oxygen and possibly also physically unstable.
- the invention is directed to a method for increasing the physical stability of a sensitive product for parenteral administration during long-term storage, comprising a fat emulsion wherein the said product is packaged in an at least one partially gas permeable primary container which is sealed in a substantially airtight envelope, in which method environmental air is removed from the envelope by applying vacuum generating means, whereafter the atmospherical pressure is restored by supplying a helium containing inert gas, preferably essentially composed of helium, and thereafter the envelope is finally sealed.
- Another object of the invention is to use helium or a helium containing inert gas for increasing the physical stability of product for parenteral administration comprising a fat emulsion.
- the invention is especially favourable for reducing creaming and for avoiding flocculation in such products.
- the products disclosed herein comprises fat emulsions, glucose solutions, carbohydrates, amino acids, electrolytes, trace elements and any mixtures thereof, which may be packaged in a single compartment container as a mixture or in multi-compartment container for subsequent mixing before administration.
- the mentioned constituents are preferably solutions, but in various applications some may appear in solid form, for subsequent mixing. Any of the said constituents can further comprise one or several compounds with an additional therapeutical or diagnostical activity.
- the products comprise components to be used as infusion solutions in therapy and/or nutrition.
- the envelope or "secondary package” is made of an airtight flexible or semi-rigid material which can be an aluminium foil laminated with one or several polymer films.
- airtight we mean a material that both can prevent the ambient atmosphere to penetrate the envelope and that prevents helium in the interior atmosphere to leak out in other ways than through slow diffusion.
- the helium for the interior atmosphere can be taken from a variety of sources, but it will have to fulfil the USP monography.
- the term helium containing inert gas used in the present text is preferably a gas containing at least 50 % helium, wherein other inert gases may be present
- other compositions are also to be considered be a part of the present invention provided functionally inert alternatives can be added.
- the helium atmosphere will consist of a dominating part of helium, but certain small amounts of other inert or rare gases are not considered to affect the improved storability of the products according to the present invention.
- Most preferred is a gas essentially composed of helium with minor amounts of other functionally inert gases.
- the primary package containing the product for parenteral administration is preferably made of materials compatible with its contents, which are sensitive medical or nutritional compositions.
- materials compatible with its contents which are sensitive medical or nutritional compositions.
- EVA Ethylene Vinyl Acetate
- EVA is often used as the major component in medical bags for storing infusion fluids with minor amounts of antioxidant additives and it is partially gas permeable.
- Other materials are of course also possible to use, but they are preferably compatible with materials to be used in medicine and in parenteral nutrition.
- the primary package can be single or multi-compartmented and can be provided with means to open the compartments for mixing of their contents immediately prior to the use.
- the product to be protected during storage according to the invention can be any liquid or solid or semi-solid material that is easily perishable by the ambient atmosphere, but will always contain at least one unstable constituent.
- an oxygen scavenger can be positioned in the space between the primary and secondary packages.
- Useful oxygen scavengers are for example described in the European Patent Specifications EP 0093796 and EP 0268848.
- the process for the manufacture of the said sealed envelope is principally performed by the following steps.
- the primary packages which can be plastic bags, are aseptically filled with their contents in a sterilized isolator and thereafter weight controlled and sealed by welding.
- the assembly of the envelope is thereafter performed by placing the primary package or packages in the envelope, removing air by a connection to vacuum, produced by conventional vacuum generating means.
- the atmospherical pressure is restored by supplying a helium containing gas or a gas essentially composed of helium and thereafter is the envelope welded and sealed.
- the finished product is preferably stored at a temperature between 2- 8°C.
- the envelope is opened just prior to the administration and the helium atmosphere is allowed to evaporate.
- the primary package containing fluids for parenteral administration will then be handled as any ordinary package or bag containing infusion solutions to be administered to a patient
- the fluids will initially contain a certain amount of dissolved helium which gradually will evaporate during the administration due to its volatility.
- a helium containing inert gas or an atmosphere essentially composed of helium for the storage of a package of parenterally administerable fluids solves the problem with gas bubble formation during administration at room temperature. This appears to be caused of the low solubility of helium both in fats and in aqueous solutions.
- the solubility of helium in fats is about one sixth of that of nitrogen, and the solubility of helium in aqueous solutions decrease seven times less than the solubility of nitrogen, when the temperature rises from 0°C to 30°C.
- Table 1 show that helium is less soluble than nitrogen in all the tested fluids, and most notably in lipids, a major constituent of many important nutrients for parenteral use.
- the solubility of helium increases, as a contrast, when the temperature rises (+0.3% /°C).
- the solubility coefficients and their variation in response to temperature changes reveal that fluids stored under influence of helium contain no gas bubbles when reheating. The probability of injecting bubbles will be close to zero when administering a helium stored fluid. If, due to some handling error, a helium bubble is accidentally administered, it would dissolve much more rapidly in plasma than a similar nitrogen bubble because of the lack of dissolved helium in the body fluids. Besides that, the amounts of dissolved helium from a helium saturated nutrient will not be able to induce any toxic effects in humans at atmospherical pressure. The amount of dissolved helium in a nutrient can be evaluated and compared with the quantity of helium dissolved in the blood of a diver diving to the saturation depth of 300 m.
- the stability of products stored in an atmosphere essentially composed of helium is evaluated in tests showing that KabiMix Novum 740 (A TPN- mixture containing a lipid emulsion and a solution of amino acids, glucose and electrolytes) is physically and chemical stable for six months when stored in an atmosphere essentially composed of helium at a temperature of 5 ⁇ 3°C.
- the studied parameters are residual oxygen, pH, osmolality, mean droplet size and visual inspections of creaming and emulsion appearance for batches stored under a nitrogen atmosphere compared to those stored under a helium atmosphere.
- Tables 2A and 2B shows comparisons of visual emulsion appearance for different batches stored under nitrogen and helium. The visual inspection tries to define the free oil formation on surface of the cream layer. The tested products are judged to acceptable or refused according to pre-determined standards.
- Stability tests are also successfully performed for a preparation for total parenteral nutrition containing a lipid emulsion and a solution of amino acids and glucose, which subsequently have led to a registered product, KabiMix 2400 kcal, packed under helium with a six months shelf-life. These tests also confirm that helium stored preparations are physically stable for at least six months at a temperature of 5 ⁇ 3°C.
- the studied parameters were residual oxygen, pH, osmolality, particle size distribution and visual inspections of the appearance of the product and the creaming layer.
- Tables 3A to C shows a creaming determination performed visually by inspecting bags filled with KabiMix 2400 kcal stored under nitrogen or helium. The results of Tables 3A to C show that creaming in millimetres are reduced when using helium as a storage medium.
- the creaming effect is to a certain extent a reversible phenomenon, so when a package or a bag containing the mixture is squeezed or agitated will the effect decrease.
- the reversibility of creaming will be especially distinct if helium is used as a protective gas and the nutrient solution will thus be easier to redisperse before administration.
- Table 4 shows the stability results for a TPN-preparation comparable to the KabiMix products with incorporated trace elements.
- the results from Tables 2 to 4 clearly show that helium provides excellent protection from chemical degradation from oxygen and also a surprising benefit in the physical stability, such as creaming, when compared to nitrogen storage. It is clearly apparent that helium possibly in a dissolved for has an influence on the emulsion stability.
- Helium storage according to the present invention will provide an opportunity to prolong safe storage of products for parenteral nutrition and especially those having added compounds for total parenteral nutrition.
