A liposome-capsule dosage unit system for the delivery of a biologically active material is formed by encapsulating a biologically active materials in liposomes and then placing the liposome encapsulated material into a capsule. The capsule is typically a soft gel capsule or a two piece capsule capable of tolerating a certain amount of water. A less water tolerant capsule can be employed if the liposomes are dehydrated prior to placement within the capsule. Biologically active material include drugs, nutritional supplements, vitamins, minerals, enzymes, hormones, proteins and polypeptides. The system is especially suited for the delivery of materials with poor oral solubility, materials that are not absorbed or are poorly absorbed from the gastrointestinal tract, and materials that have conventionally been given by an invasive route. The system can be administered orally, intra-occularly, intranasally, rectally, or vaginally. |
