Patent number: 10034899Abstract: The invention is a solid oral dosage form that is designed to deliver a supraphysiological dose of molecular iodine of 3 to 60 mg per day. The solid oral dosage form is designed to have a low risk of thyroid related adverse clinical events for patients with deficiencies of certain minerals. The solid oral dosage form includes a source of iodine, a reactive agent, and calcium or iron. The solid oral dosage form may include one or more of selenium, vitamin A, vitamin D, zinc, gamma-linolenic acid, vitamin B1, and magnesium. The solid dosage form may further comprise an enteric coating that coats ingredients that are absorbed predominantly from the intestines, such as vitamin A and D, and does not coat the source of iodine and the reactive agent.Type: GrantFiled: November 22, 2014Date of Patent: July 31, 2018Assignee: BioPharmX, Inc.Inventors: Jack Kessler, Robert Kehl Sink
