Described herein are oral pharmaceutical compositions comprising labile, air-, moisture-, or heat-sensitive active pharmaceutical ingredients and methods for making the same. In particular, immediate release capsules comprising non-aqueous fills and active pharmaceutical ingredients are described.
Many active pharmaceutical ingredients (APIs) are labile or sensitive to light, oxidation, moisture, or heat. Further, some compounds are poorly soluble. These attributes can cause difficulties in the manufacturing process and reduce the shelf life of the resulting product.
Accordingly, there is a need for oral pharmaceutical compositions that protect the active pharmaceutical ingredient from light, air, moisture, and heat during manufacturing and storage. The absorption of moisture by the API during processing can reduce the content of the pharmaceutically active substance in the dosage form because of the increased weight caused by the uptake of water. Pharmaceutical compositions with a tendency to absorb moisture need to be protected from moisture during storage, e.g., by the addition of suitable drying agents or by storing the drug in an environment where it is protected from moisture. In addition, the uptake of moisture may reduce the content of pharmaceutically active substance during manufacture if the pharmaceutical substance is exposed to the environment without being protected from moisture in any way. Preferably, therefore, a pharmaceutically active substance should be only slightly hygroscopic.
Pharmaceutical substances that are sensitive to moisture and light often undergo hydrolytic degradation or photodegradation, respectively. Accordingly, moisture and light sensitive substances often undergo polymorphic form transformations (e.g., enantiomeric conversion). These processes can result in the generation of degradation products and impurities that reduce the efficacy, potency, and activity of the pharmaceutical substance requiring additional dosages of the pharmaceutical substance. Taking additional dosages of pharmaceuticals places an undue burden on patients. In addition, active pharmaceutical degradation products can act antagonistically to the drug substance or even become genotoxic, resulting in unforeseen side effects in patient populations.
Currently, there are limited options for protecting active drug substances from moisture degradation. For example, only slightly hygroscopic or non-hygroscopic excipients are chosen to help protect the active drug substances during formulation, which unduly limits the range of pharmaceutical ingredients for further formulating pharmaceutical compositions having moisture sensitive drugs. Other methods utilize special external polymeric coatings (e.g., Kollicoat), which function to reduce the absorption of external water by soft gel capsules. However, external coatings do not prevent migration of water from the capsule shell to the active drug substance and are often complicated to apply and result in an increased variation in coating. These variations in coatings result in decreased drug stability between soft gel capsules, which affects proper dosing.
In addition, moisture sensitive active drug substances are often incorporated into tablets or encapsulated within hard capsules to eliminate the migration of moisture. However, there is a demand from consumers for pharmaceutical compositions having soft gel capsules, which are easier to ingest than hard capsules or tablets. Thus, new pharmaceutical soft gel formulations which address the physicochemical requirements and that are cost effective and feasibly manufactured are needed. Furthermore, the problem addressed by the oral pharmaceutical composition described herein is to provide a pharmaceutically active substance comprising soft gel capsules which not only is characterized by a high pharmacological potency, but also satisfies the abovementioned physicochemical requirements as far as possible.

In one embodiment, enteric soft capsule shell compositions can be made by dissolving the enteric acid-insoluble polymer in an aqueous solution of an alkali neutralizing agent such as ammonia, sodium hydroxide, potassium hydroxide, or liquid amines such as tri-ethanol amine or ethylene diamine. The amount of alkali is adjusted to give a final pH value of the gel mass less than or equal to about pH 9.0. In one embodiment, the final pH does not exceed 8.5.

The fugitive ammonia evaporates during degassing. Using the foregoing process, the alkali concentrations do not require an additional step such as heating or neutralizing with acid in order to neutralize the gel mass.
In another embodiment described herein, the enteric soft capsule shell can be made by using an aqueous dispersion of the acid-insoluble polymer by adding alkaline materials such as ammonium, sodium, or potassium hydroxides, other alkalis, or a combination thereof that will cause the enteric acid-insoluble polymer to dissolve.

The active form of dabigatran and its acyl glucuronides are competitive, direct thrombin inhibitors. Because thrombin (serine protease) enables the conversion of fibrinogen into fibrin during the coagulation cascade, its inhibition prevents the development of a thrombus. Both free and clot-bound thrombin and thrombin-induced platelet aggregation are inhibited by the active moieties.
In another embodiment described herein, is a method for orally administering a dosage form of dabigatran for the treatment, amelioration, prophylaxis, or reducing the onset of or symptoms of a coagulation disorder.
