<p>All entries in the <ahref="antibiotics.html">antibiotics</a> data set have three different identifiers: a human readable EARS-Net code (column <code>ab</code>, used by ECDC and WHONET), an ATC code (column <code>atc</code>, used by WHO), and a CID code (column <code>cid</code>, Compound ID, used by PubChem). The data set contains more than 5,000 official brand names from many different countries, as found in PubChem. Not that some drugs contain multiple ATC codes.</p>
<p>All these properties will be searched for the user input. The <code>as.ab()</code> can correct for different forms of misspelling:</p><ul><li><p>Wrong spelling of drug names (such as "tobramicin" or "gentamycin"), which corrects for most audible similarities such as f/ph, x/ks, c/z/s, t/th, etc.</p></li>
<li><p>Too few or too many vowels or consonants</p></li>
<li><p>Switching two characters (such as "mreopenem", often the case in clinical data, when doctors typed too fast)</p></li>
<li><p>Digitalised paper records, leaving artefacts like 0/o/O (zero and O's), B/8, n/r, etc.</p></li>
</ul><p>Use the <code><ahref="ab_property.html">ab_*</a></code> functions to get properties based on the returned antibiotic ID, see <em>Examples</em>.</p>
<p>Note: the <code>as.ab()</code> and <code><ahref="ab_property.html">ab_*</a></code> functions may use very long regular expression to match brand names of antimicrobial agents. This may fail on some systems.</p>
