remove italics from align

\begin{align*}
P2P &- Peer-to-Peer Network\\
%.....
\end{align*}

I have a Abbreviation page in my PDF. For aligning all the '-' I am using align*. All the content inside align shows up in italics. How do I make the content inside align appear normal and not italic?

• amsmath provides \text{...} for text-related content, which this clearly is. You may also consider tabular as an alternative. – Werner Feb 12 '13 at 7:54
