Many biological medicines draw safety warnings

Why does follow-on monitoring for safety seem like such a strange idea?...

WASHINGTON, Oct 21 (Reuters) - About a quarter of biological medicines approved in the United States and Europe since 1995 have triggered safety warnings in the years after entering the market, Dutch researchers said on Tuesday.

Immune system disorders, infusion reactions, infections and cancer concerns were among the reasons for safety warnings for biological medicines, which are made with proteins derived from living cells rather than the chemicals used in typical drugs.

These medicines, called biologics or biologicals, are typically injected and treat a range of conditions including anemia, rheumatoid arthritis, hepatitis and cancer.

Thijs Giezen of Utrecht University in the Netherlands and colleagues tracked safety-related regulatory actions involving 174 biological medicines approved in the United States or the European Union between January 1995 and June 2007.

vomistop 10 mg is an enemy of infection medication. It encourages you to quit feeling or being debilitated. It can likewise be used to treat stomach torment in case you're having the end of life care. Domperidone is now and then used to increase milk supply.
