Albuterol and ipratropium is a combination bronchodilator that relaxes muscles in the airways and increases air flow to the lungs.

The AMT, for the uninitiated, is the Internal Revenue Service's way of trying to keep the wealthy from deducting away their entire income tax bills. Rates are lower than ordinary income tax rates, but fewer deductions are allowed. If your AMT tax bill is greater than your regular income tax bill, you pay AMT. Everything that's taxable as ordinary income is taxable as AMT income, so AMT isn't an issue for bonds other than munis.
