Income Tax Disclosure [Abstract]
Income Taxes	Note 6 – Income Taxes At December 31, 2016, there were $47.1 million in net operating loss carryforwards, subject to applicable limitations, available to us for federal purposes which will expire beginning for the year ended December 31, 2020 through 2036. Additionally, there were $22.1 million in net operating loss carryforwards, subject to limitations, available to us for state purposes which will expire beginning for the year ended December 31, 2020 through 2036. Based upon preliminary estimates, we believe that a significant portion of our income tax liability of $19.5 million arising from our taxable gain for federal and state income tax purposes from the sale of the Cold-EEZE^® Business will be offset to the extent of our current year losses from operations, the write-off for tax purposes of the tax-basis of the Cold-EEZE^®Business and the available net operating loss carryforwards at the federal and state levels. However, for state income tax purposes, based upon the available state net operating loss carryforwards and corresponding limitations, we estimate a net income tax expense arising from the sale of the Cold-EEZE^® Business of $1.3 million. Utilization of net operating loss carryforwards may be subject to limitations as set forth in Section 382 of the Internal Revenue Code (“Section 382”). Based on our preliminary Section 382 analysis, we do not believe that our current net operating loss carryforwards are subject to these limitations as of June 30, 2017. However, until we complete a final Section 382 analysis upon filing of our 2017 income tax return, there can be no assurances that our preliminary analysis is accurate or complete. Should we identify any limitations upon the completion of our final Section 382 analysis, the impact could be material to our consolidated financial statements and that we could incur additional income tax expense arising from the sale of the Cold-EEZE^® Business. For the six months ended June 30, 2017, we charged to discontinued operations $19.5 million for estimated federal and state income taxes arising from the sale of the Cold-EEZE^® Business and we have realized an income tax benefit from continuing operations of $18.1 million as a consequence of the utilization of the federal and state net operating losses. Subsequent to the income tax effects arising from the sale of the Cold-EEZE^® Business, we will continue to have net operating loss carry-forwards for federal income tax purposes. Until sufficient taxable income to offset the temporary timing differences attributable to operations, and the tax deductions attributable to option, warrant and stock activities are assured, a valuation allowance equaling the total deferred tax asset is being provided. As a consequence of the accumulated losses of the Company, we believe that this allowance is required due to the uncertainty of realizing these tax benefits in the future.

Note 6 – Income Taxes

At December 31, 2016, there were $47.1 million in net operating loss carryforwards, subject to applicable limitations, available to us for federal purposes which will expire beginning for the year ended December 31, 2020 through 2036. Additionally, there were $22.1 million in net operating loss carryforwards, subject to limitations, available to us for state purposes which will expire beginning for the year ended December 31, 2020 through 2036.

Based upon preliminary estimates, we believe that a significant portion of our income tax liability of $19.5 million arising from our taxable gain for federal and state income tax purposes from the sale of the Cold-EEZE^® Business will be offset to the extent of our current year losses from operations, the write-off for tax purposes of the tax-basis of the Cold-EEZE^®Business and the available net operating loss carryforwards at the federal and state levels. However, for state income tax purposes, based upon the available state net operating loss carryforwards and corresponding limitations, we estimate a net income tax expense arising from the sale of the Cold-EEZE^® Business of $1.3 million.

Utilization of net operating loss carryforwards may be subject to limitations as set forth in Section 382 of the Internal Revenue Code (“Section 382”). Based on our preliminary Section 382 analysis, we do not believe that our current net operating loss carryforwards are subject to these limitations as of June 30, 2017. However, until we complete a final Section 382 analysis upon filing of our 2017 income tax return, there can be no assurances that our preliminary analysis is accurate or complete. Should we identify any limitations upon the completion of our final Section 382 analysis, the impact could be material to our consolidated financial statements and that we could incur additional income tax expense arising from the sale of the Cold-EEZE^® Business.

For the six months ended June 30, 2017, we charged to discontinued operations $19.5 million for estimated federal and state income taxes arising from the sale of the Cold-EEZE^® Business and we have realized an income tax benefit from continuing operations of $18.1 million as a consequence of the utilization of the federal and state net operating losses.

Subsequent to the income tax effects arising from the sale of the Cold-EEZE^® Business, we will continue to have net operating loss carry-forwards for federal income tax purposes. Until sufficient taxable income to offset the temporary timing differences attributable to operations, and the tax deductions attributable to option, warrant and stock activities are assured, a valuation allowance equaling the total deferred tax asset is being provided. As a consequence of the accumulated losses of the Company, we believe that this allowance is required due to the uncertainty of realizing these tax benefits in the future.
