## Abstract

The present invention relates to complexes consisting of immunoglobulins and polysaccharides for oral and transmucosal use. The polysaccharides comprised in the complexes according to the invention form an envelope which protects and carries immunoglobulins allowing their systemic absorption through the gastric and mucosal district. Immunoglobulins have a different specificity depending on the required therapeutic effect. They are used in passive immunoprophylaxis for the prevention or therapy of infections caused by pathogenic agents such as virus, bacteria, parasites, or they are used in the modulation of endogenous bio-chemical balances, or in the detoxification from drugs of abuse, medicines, toxins.

## Claims

### Claim 1

An isolated composition consisting of immunoglobulins as the active ingredient, a polysaccharide selected from the group consisting of chitosanes and alginates, wherein the polysaccharidic molecules are neither chemically cross-linked to the immunoglobulins, nor to each other, in combination with suitable excipients and diluents.

### Claim 2 (depends on 1)

The composition according to claim 1, wherein the immunoglobulins and the polysaccharides are associated by means of non-covalent links.

### Claim 3 (depends on 1)

The composition according to claim 1, wherein the chitosanes are selected from the group consisting of chitosanes with a molecular weight below 150,000 Da, methylglycolchitosane, and salts thereof.

### Claim 4 (depends on 3)

The composition according to claim 3, wherein the chitosane is metilglicolchitosane or its salts.

### Claim 5 (depends on 1)

The composition according to claim 1, wherein the alginates are selected from the group consisting of polymannuronic acid, alginic acid and its enzymatic fragments, and salts thereof.

The composition according to claim 6, wherein said immunoglobulins are IgG or their fragments F(ab′)2 or F(ab) or scFv.

### Claim 8 (depends on 1)

The composition according to claim 1, wherein said immunoglobulins are specific for substances selected from the group consisting of toxins, infectious agents, hormones, enzymes, proenzymes, drugs of abuse, medicines, bioactive peptides, metabolites, physiologic precursors and their antigenic components.

### Claim 9 (depends on 8)

The composition according to claim 8, wherein said toxins are of mycotic origin.

### Claim 10 (depends on 9)

The composition according to claim 9, wherein said toxins are selected from the group consisting of ochratoxin, aflatoxin, zearalonon and fumonisine.

### Claim 11 (depends on 8)
