Benefits of technology

[0006] The present inventors have found a nasal composition that unlike those described in the foregoing JP-6242888-B and JP-1059841-A uses non-solubilized powdered insulin and a special, aggregate crystalline cellulose with a particle diameter of less than 150 μm, which in comparison with existing compositions, significantly increases insulin absorption enabling enhanced therapeutic efficacy in the treatment of diabetes patients.

Problems solved by technology

This troublesome procedure is only one of the many problems associated with the treatment of diabetes.
However, the present inventors have no information on the practical application of insulin formulations for nasal administration including these related prior arts.

Embodiment Construction

[0020] Any form of modified or unmodified insulin used in treating diabetes in humans can be used with the present invention, regardless of its origin. Accordingly, the term ‘Insulin’ as used here is deemed to mean all types in current or future clinical use, having the same physiologically activity as that of human insulin including human insulin, refined bovine insulin, refined porcine insulin, semi-synthesized human insulin, human isoinsulin, genetically modified human insulin or its variants thereof. Powder forms of these types of insulin or insulin that is only slightly soluble in water or almost insoluble in water (Corresponding to 1 g of powdered insulin requiring solvent in excess of 1000 mL and less than 10000 mL, or in excess of 10000 mL; see 13th Japan Pharmacopoeia, Principles of Operation A-51) even if modified, can also be preferably used with the present invention.

[0021] Given that the type of insulin described previously is slightly soluble in water or almost insolu...

Abstract

Provided is an insulin-containing granulated composition for nasal administration comprising a crystalline cellulose aggregate having a specific particle diameter distribution as a carrier. Such granulated composition for nasal administration can efficiently increase a blood insulin concentration.

Description

TECHNICAL FIELD [0001] The present invention relates to a pharmaceutical formulation, the distinguishing features of which are that it is granular in form and is administered via the nasal mucosa. Specifically, the present invention relates to a granulated composition of insulin for nasal administration as a therapeutic treatment for diabetes. BACKGROUND ART [0002] At present, the insulin used in the clinical treatment of diabetes is in the form of an injectable formulation, and in most cases is self-administered by a comparatively simple subcutaneous injection. The characteristics of this type of drug are such that the patient must self-administer before meals, once to four times a day for life. This troublesome procedure is only one of the many problems associated with the treatment of diabetes. [0003] Preparations for nasal administration have been proposed as a remedy to the difficulties associated with subcutaneous administration. For example, an insulin formulation in which 90...
