Treatment of thrombocytopenia using orally administered interferon
An interferon composition is provided for enhancing the platelet count, reducing the recurrence rate of hepatitis, and/or improving the social function of hepatitis patients. The method comprises administering a low dose of IFN (about 5 IU to about 2500 IU of IFN-alpha) to a patient in need thereof. In one embodiment the IFN is alpha IFN or beta IFN, and more particularly, in one embodiment the administered biologically active IFN is human alpha IFN.
1. A method of treating thrombocytopenia, the method comprising: identifying a patient with platelet blood levels of less than 150,000 platelets per microliter; orally administering a daily dosage of 500 IU of an interferon-alpha to the patient to stimulate a more rapid increase of blood platelets to a normal level of blood platelets in the patient, wherein the normal level of blood platelets in the patient is at or above 150,000 platelets per microliter.
2. The method of claim 1 , wherein the thrombocytopenia is due to a reduction of blood platelets in the patient receiving the interferon-alpha intravenously.
3. The method of claim 1 , wherein the interferon-alpha is administered bucally.
4. The method of claim 1 , wherein the interferon-alpha is formulated in a liquid or a saliva-soluble lozenge dosage form.
5. The method of claim 4 , wherein the orally administered interferon-alpha is formulated as the saliva-soluble lozenge dosage form, and wherein orally administering comprises, introducing tile saliva-soluble lozenge dosage form into the mouth of tile patient; allowing the saliva-soluble lozenge dosage form to dissolve in the patient's mouth to form an interferon-containing solution; and contacting the interferon-containing solution with the oral mucosa and the pharyngeal mucosa of the patient.
6. The method of claim 1 , wherein orally administering the interferon-alpha comprises a first interferon-alpha and a second interferon-alpha.
7. The method of claim 6 , wherein the first interferon-alpha is an interferon-α2b and the second interferon-alpha is an interferon-α8a.
8. The method of claim 1 , wherein the patient is infected with hepatitis C virus.
