id="main_column" "> <div class="item last"> <h1 class="headline">ATCvet</h1> <div class="body"><p>The <em>ATCvet</em> system for the classification of veterinary medicines is based on the same overall principles as the <em>ATC</em> system for substances used in human medicine. In most cases an ATC code exists which can be used to classify a product in the ATCvet system. The ATCvet code is then created by placing the letter Q in front of the ATC code. In some cases, however, specific ATCvet codes are created, e.g. Antibacterials for intramammary use (QJ51) and Immunologicals (QI).</p> <p>In both the ATC and the ATCvet systems, preparations are divided into groups, according to their therapeutic use. First, they are divided into 15 <em>anatomical groups</em> (1st level), classified as QA-QV in the ATCvet system, on the basis of their main therapeutic use.</p> <p>Within most of the 1st level groups, preparations are subdivided into different <em>therapeutic main groups</em> (2nd level), coded for example as QA01, QA02, QA03 etc. Two levels of <em>chemical/therapeutic/pharmacological subgroups</em> (3rd and 4th levels), e.g. QA02A, QA02B etc. at the 3rd level and QA02AA, QA02AB etc at the 4th level, provide further subdivisions. At a 5th level, e.g. QA02AA01, <em>chemical substances</em> are classified. (This subdivision does not apply to QI - Immunologicals.)</p> <p>This is illustrated by the following examples:</p> <p><strong>Anatomical groups (1st level):</strong></p> <p> <table border="0"> <tbody> <tr style="background-color: #d9dbdd;"> <td><strong>ATCvet<br/>1st level</strong> </td> <td><strong>Name</strong></td> <td><strong>ATC</strong></td> </tr> <tr style="background-color: #eaecec;"> <td>QA</td> <td>Alimentary tract and metabolism</td> <td>A</td> </tr> <tr style="background-color: #d9dbdd;"> <td>QB</td> <td>Blood and blood forming organs</td> <td>B</td> </tr> <tr style="background-color: #eaecec;"> <td>QC</td> <td>Cardiovascular system</td> <td>C</td> </tr> <tr style="background-color: #d9dbdd;"> <td>QD</td> <td>Dermatologicals</td> <td>D</td> </tr> <tr style="background-color: #eaecec;"> <td>QG</td> <td>Genito urinary system and sex hormones</td> <td>G</td> </tr> <tr style="background-color: #d9dbdd;"> <td valign="top">QH</td> <td>Systemic hormonal preparations, excl. sex hormones and insulins  </td> <td valign="top">H</td> </tr> <tr style="background-color: #eaecec;"> <td>QI</td> <td>Immunologicals</td> <td>-</td> </tr> <tr style="background-color: #d9dbdd;"> <td>QJ</td> <td>Antiinfectives for systemic use</td> <td>J</td> </tr> <tr style="background-color: #eaecec;"> <td>QL</td> <td>Antineoplastic and immunomodulating agents</td> <td>L</td> </tr> <tr style="background-color: #d9dbdd;"> <td>QM</td> <td>Musculo-skeletal system</td> <td>M</td> </tr> <tr style="background-color: #eaecec;"> <td>QN</td> <td>Nervous system</td> <td>N</td> </tr> <tr style="background-color: #d9dbdd;"> <td>QP</td> <td>Antiparasitic products, insecticides and repellents</td> <td>P</td> </tr> <tr style="background-color: #eaecec;"> <td>QR</td> <td>Respiratory system</td> <td>R</td> </tr> <tr style="background-color: #d9dbdd;"> <td>QS</td> <td>Sensory organs</td> <td>S</td> </tr> <tr style="background-color: #eaecec;"> <td>QV</td> <td>Various</td> <td>V</td> </tr> </tbody> </table> </p> <p><strong>2nd level groups - examples from group QJ - Antiinfectives for systemic use</strong><br/>QJ51  Antibacterials for intramammary use<br/>QJ54  Antimycobacterials for intramammary use</p> <p><strong>3rd level groups - examples from group QJ51 - Antibacterials for intramammary use</strong><br/>QJ51F  Macrolides and lincosamides for intramammary use<br/>QJ51G  Aminoglycoside antibacterials for intramammary use<br/>QJ51R  Combinations of antibacterials for intramammary use</p> <p><strong>4th level groups - examples from group QJ51R - Combinations of antibacterials for intramammary use</strong><br/>QJ51RF  Macrolides, combinations with other antibacterials<br/>QJ51RG  Aminoglycoside antibacterials, combinations<br/>QJ51RV  Combinations of antibacterials and other drugs</p> <p><strong>5th level code - example from group QJ51R F - Macrolides, combinations with other antibacterials</strong><br/>QJ51RF01  Spiramycin, combinations with other antibacterials</p> <p>The complete classification of <em>ampicillin</em> for systemic use illustrates the structure of the ATC code:</p> <p> <table border="0"> <tbody> <tr style="background-color: #d9dbdd;"> <td><strong>J</strong></td> <td>General antiinfectives for systemic use (1st level, anatomical main group)</td> </tr> <tr style="background-color: #eaecec;"> <td><strong>  01</strong></td> <td>Antibacterials for systemic use (2nd level group, therapeutic main group)</td> </tr> <tr style="background-color: #d9dbdd;"> <td><strong>      C</strong></td> <td>Beta-lactam antibacterials, penicillins (3rd level group, therapeutic subgroup)</td> </tr> <tr style="background-color: #eaecec;"> <td><strong>        A</strong></td> <td>Penicillins with extended spectrum (4th level group, chemical/therapeutic subgroup)</td> </tr> <tr style="background-color: #d9dbdd;"> <td><strong>          01  </strong></td> <td>Ampicillin (5th level code, subgroup for chemical substance)</td> </tr> </tbody> </table> </p> <p>Thus, in the ATC system, all plain ampicillin products for systemic use should be classified using the code <strong>J01CA01</strong>.</p> <p>In most cases an ATC code exists which can be used to classify a product in the ATCvet system. The ATCvet code is then created by placing the letter Q in front of the ATC code.</p> <p>An ATCvet classification code is thus built up as follows:</p> <p> <table border="0" cellspacing="0" cellpadding="2"> <tbody> <tr> <td colspan="7">Example: Ampicillin</td> </tr> <tr> <td>Level</td> <td>0   </td> <td>1   </td> <td>2   </td> <td>3   </td> <td>4   </td> <td>5</td> </tr> <tr> <td>ATC code</td> <td>J</td> <td>01</td> <td>C</td> <td>A</td> <td>01</td> </tr> <tr> <td>ATCvet code   </td> <td>Q</td> <td>J</td> <td>01</td> <td>C</td> <td>A</td> <td>01</td> </tr> </tbody> </table> </p> <p> </p></div> </div> </div> <div id="last_updated"> <p><i>Last updated: 2015-01-09</i></p> </div> </div> </div> </div> <div id="left_bottom"> </div> </div> </body> </html>
