Introduction<br>Antibiotics are a critical component of human and veterinary modern medicine, developed to produce desirable or<br>beneficial effects on infections induced by pathogens. Like most pharmaceuticals, antibiotics tend to be small organic<br>polar compounds, generally ionisable, ordinarily subject to a metabolism or biotransformation process by the organism to<br>be eliminated more efficiently [1,2]. The excretion of these compounds and their metabolites occurs mainly through urine,</code> |
| <code>How many kilograms of abacavir were detected in Portugal in 2017?</code> | <code>Regarding the different regions, it has been concluded that North and West/Tejo were the regions with the higher<br>consuming values. Both regions presented a significant value (33%) for the abacavir. For the detected antiviral abacavir,<br>an amount of 1458 kg has been observed.<br>Regarding antibiotics used in veterinary medicine, the regional amount was not available.

The enzyme inhibitors, namely clavulanic acid and cilastatin, were detected once in an urban region located<br>well. This catchment point showed the most significant<br>number of pharmaceuticals.

Since 2006, marketing authorisation procedures for both human and veterinary<br>medicines must include an environmental risk assessment that comprises a prospective exposure assessment,<br>underestimating the possible impact and the occurrence of antibiotics after years of consumption.

Noticeable was the detection of enzyme inhibitors, tazobactam and cilastatin, which are both for exclusive<br>hospital use.
