Description
PACKAGING KIT FOR STATINS AND COMPOSITIONS THEREOF
Field of the Invention
This invention relates to a packaging kit comprising a sealed oxygen impermeable container comprising a statin and at least one stabilizer selected from the group consisting of an oxygen absorber, a moisture absorber or a combination thereof. It further relates to a packaging kit for a solid pharmaceutical composition of a statin comprising the statin composition and at least one stabilizer selected from the group consisting of an oxygen absorber, a moisture absorber or a combination thereof in an oxygen impermeable container.
Background of the Invention
Statins are currently among the most therapeutically effective drugs available for reducing the level of LDL in the blood stream of a patient at risk for cardiovascular disease. Statins are also known to raise HDL cholesterol levels and decrease total triglyceride levels. The mechanism of action of statins has been elucidated in some detail. It is believed that statins disrupt the biosynthesis of cholesterol and other sterols in the liver by competitively inhibiting the 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase enzyme ("HMG-CoA reductase"). HMG-CoA reductase catalyzes the conversion of HMG-CoA to mevalonate, which is the rate determining step in the biosynthesis of cholesterol. Consequently, its inhibition leads to a reduction in the rate of formation of cholesterol in the liver.
The main statins currently used in therapeutics are: pravastatin, simvastatin, lovastatin, fluvastatin, atorvastatin and rosuvastatin. lovastatin, simvastatin and pravastatin are fully or partially fermentation based products, whereas fluvastatin, rosuvastatin and atorvastatin are entirely synthetic. Simvastatin is a chemically modified 2,2-dimethyl- butyrate analogue of lovastatin. Pravastatin is a purified active metabolite of mevastatin with an open hydroxyacid instead of a lactone ring. All the statins are relatively unstable, and their degradation may be catalyzed by several parameters like oxygen, humidity, low pH and temperature.
These statins are known to occur in various crystalline as well as amorphous forms. However, amorphous forms may be susceptible to oxidation, heat, light, moisture and low pH, as compared to crystalline forms. Impurities generated upon degradation of active substances may reduce the therapeutic effects of an active substance and unnecessarily burden the body with degradation products. For example, oxidative degradation of atorvastatin may lead to impurities such as Atorvastatin diepoxide, dihydroxy epoxide or diketoepoxide.
There have been various attempts to stabilize various statins by using various packaging options.
International Patent Publication WO 2004/032920 describes storage of amorphous atorvastatin calcium solid dosage forms in an inert atmosphere and packaging the dosage form in a material that is not permeable to gases. In one example, tablets containing the drug were packaged in aluminum foil blisters, the blisters having an argon atmosphere.
There is still a need for providing a packaging system for a statins so as to enhance their stability. This can be provided by using an oxygen impermeable container along with one stabilizer such as oxygen or moisture absorber. This packaging system may not require controlling the atmospheric conditions during the time of packaging, which is a cumbersome process.
Summary of the Invention
In one general aspect, there is provided a packaging kit comprising a sealed oxygen impermeable container comprising a statin and at least one stabilizer selected from the group consisting of an oxygen absorber, a moisture absorber or a combination thereof.
In another general aspect, there is provided a packaging kit for a solid pharmaceutical composition of a statin comprising a sealed oxygen impermeable container comprising said composition and at least one stabilizer selected from the group consisting of an oxygen absorber, a moisture absorber or a combination thereof.
In another general aspect, there is provided a method of stabilizing a statin by packaging said statin in a sealed oxygen impermeable container along with at least one stabilizer selected from the group consisting of an oxygen absorber, a moisture absorber or a combination thereof.
In another general aspect, there is provided a method of stabilizing pharmaceutical composition comprising a statin by packaging said composition in a sealed oxygen impermeable container along with at least one stabilizer selected from the group consisting of an oxygen absorber, a moisture absorber or a combination thereof.
Description of the Invention
As used herein the term "statin" refers to any crystalline or amorphous form of pravastatin, simvastatin, rosuvastatin, lovastatin, fluvastatin, atorvastatin and cerivastatin. Pharmaceutically acceptable base addition salts of statins are formed with metals or amines, such as alkali and alkaline earth metals or organic amines. Examples of metals used as cations are sodium, potassium, magnesium, calcium, and the like. Examples of suitable amines are N, N-1-dibenzylethylenediamine, chloroprocaine, choline, diethanolamine, dicyclohexylamine, ethylenediamine, N-methylglucamine, and procaine.
The term "oxygen impermeable" as used herein means a material having an oxygen permeability of less than 5 cm3/sqm.day.atm, more particularly 2 cm3/sqm.day.atm.
The container as used herein include air-tight drums or bottles made up of oxygen impermeable material such as glass or plastic such as polyvinyl chloride, polyethylene terpthalate, ethylene vinylalcohol. Multilayer containers containing polyvinyl chloride, polyethylene terpthalate, ethylene vinylalcohol may additionally comprise layers of oxygen permeable materials for example, polyethylene such as HDPE (high density polyethylene), LDPE (low density polyethylene), polypropylene or polystyrene, however the oxygen barrier properties should not be altered.
Glass container is tamper-proof, transparent, impermeable to gas and resistant to any interaction between containers and the content, and hence provides a total product
safety. Also, for products which are light sensitive amber glass may be used which further protects the product from harmful UV light.
Ethylene vinyl alcohol provides excellent oxygen impermeability, however, it is moisture sensitive, hence a multilayer container may be used wherein ethylene vinyl alcohol may be coextruded with polyethylene or polypropylene, wherein polyethylene or polypropylene help to overcome moisture sensitivity by acting as a barrier to moisture. Coextrusion with polyethylene provides additional advantage of providing transparent container. This coextruded layer comprising ethylene vinylalcohol sandwiched between two layers of HDPE having a total thickness of 1.3 mm was found to have oxygen permeability of 0.45 cm3/sqm.day.atm as measured according to ASTM Fl 307 (American Society for Testing and Materials). Coextruded layer with polyethylene terpthalate as disclosed US 6,521,159 may also be used.
The container may be sealed using heat induction seal wherein the sealing liner is additionally made up of oxygen impermeable film such as aluminum.
The term "oxygen absorbers" as used herein, means agents used to trap oxygen that is present in the overhead space of closed container. Concerning the chemical and physical mechanisms of active oxygen absorbers, they can be classified into the following categories:
• inorganic, metal based oxygen absorber
• ascorbic acid based absorber
• enzymatic absorber
• polymer based oxygen absorber
Inorganic, metal-based oxygen absorbers are inexpensive, available with different 02-scavenging capacities in sachets and are commonly used in foods and beverages. The broadest range of iron-based products are offered by Mitsubishi Gas Chemicals Ageless™. Similar products are also offered by Multisorb under the trade name Fresh Pax™. The
reaction is based on the well-known corrosion of iron. Another variant for oxygen absorbers is self- activated oxygen absorbers which involve combining moisture-retaining additives to metals such as iron. Another modification of metal absorbers is "stealth absorbers", which is also based on corrosion of iron but the metal is embedded in an extendable plastic. Ascorbic acid is a well-known preserving agent and may also be used as one of the options. There are also available enzymatic oxygen absorber which are based on glucose/glucose oxidase.
Polymer based scavengers are suitable for moisture protected applications. Polymer-based compounds consist of high molecular weight, ethylenically-unsaturated hydrocarbons. An activation step often enables the user to start the oxygen scavenging when desired.
Commercially available sachets include D Series FreshPax™ (available from Multisorb Technologies Inc), Ageless™ Z (Ageless-Z is designated as Z-IOO, Z-1000, etc., to indicate the milliliters of oxygen with which a single packet will react), StabilOx D (available from Multisorb Technologies Inc) and ZPTJ™ sachets (both available from Mitsubishi Gas Corporation), O-Buster™ (available from Hsiao Sung Non-Oxygen Chemical Co., Ltd), Bioka™ Oxygen Absorber (available from Bioka Ltd) and the like.
The moisture absorbers include activated carbon, silicas, zeolites, molecular sieves, hydrogels, calcium oxide and diatomaceous earth. The particular moisture -retaining materials used will depend upon the humidity level of the environment. For example, in a very low-humidity environment, a moisture-carrying material such as a hydrogel that partially binds water may be preferred. The moisture absorber can be supplied in the form of a sachet, cartridge or canister. A preferred form is a canister of silica gel, such as SorBit™ (commercially supplied by Sud-Chemie Corporation). Multisorb provides variety of moisture absorbers under trade name of Natrasorb M, Natrasorb S, Natrasorb C, and Hi-dry, which comprise diatomaceous earth, silica gel, calcium oxide and molecular sieve, respectively.
Further, there are certain commercially available packets or sachets which comprise a combination of oxygen absorber and moisture absorber such as Pharmakeep
oxygen- and moisture-absorbing packets (PharmaKeep KD or KC) (distributed jointly by
Sud-Chemie and Mitsubishi Gas Chemical Company).
In addition, combination of oxygen absorber and moisture absorber can be used together in a packaging kit. Oxygen absorbers usually lead to an increase in moisture levels, hence a combination of moisture absorber and oxygen absorber will regulate moisture levels as well as oxygen levels.
The moisture/oxygen absorber may be in the form of packet, sachet, strips or canisters. The packet, sachet, strips or canisters may additionally comprise a moisture- indicating card.
In one of the embodiments, a packaging kit for a statin can be obtained by
i) putting the statin and oxygen absorber and/or a moisture absorber into a oxygen impermeable drum; and
ii) sealing the drum with heat induction seal.
In another embodiment, a packaging kit for a solid pharmaceutical composition comprising statin is obtained by:
i) putting the composition into impermeable bottle along with an oxygen absorber and/or a moisture absorber;
ii) sealing the bottle with heat induction seal.
The composition as used herein includes both immediate and extended release compositions. The statin may be present in the composition between 1% to about 50% by weight of the composition.
The solid pharmaceutical composition includes tablet, capsule, pills, dry powder, dragees or granulate.
The composition may further contain other pharmaceutically acceptable excipients, such as antioxidants, chelating agents, alkali metal salt additives, alkaline earth metal salt additives, binders, diluents, disintegrants, surfactants or lubricants.
Examples of suitable pharmaceutically acceptable antioxidants may include butylated hydroxyanisole (BHA), sodium ascorbate, butylated hydroxytoluene (BHT), sodium sulfite, propyl gallate, tocopherol, citric acid, malic acid, and ascorbic acid.
The chelating agents may be selected from amongst one or more of those suitable chelating agents known in the art. Examples of suitable chelating agents include disodium edetate (EDTA). The chelating agents can be present at a concentration of up to approximately 5% by weight of the composition.
Alkali metal salt additives may be, for example, one or more of sodium carbonate, sodium hydroxide, sodium silicate, disodium hydrogen orthophosphate, sodium aluminate or other suitable alkali metal salts. In particular, the stabilizing alkali metal salt additive may be, for example, sodium carbonate or disodium hydrogen orthophosphate, although the other alkali metal salt additives may also be selected. Alkaline earth metal salt additives can include one or more of calcium carbonate, calcium hydroxide, magnesium carbonate, magnesium hydroxide, magnesium silicate, magnesium aluminate, and aluminum magnesium hydroxide.
The binders may be, for example, one or more binders known in the art. Examples of suitable binders include starch, polyvinyl pyrrolidone, hydroxypropyl cellulose, hydroxypropyl methylcellulose, and carboxymethylcellulose.
The diluents may be, for example, one or more diluents known in the art.
