What is the term for the conversion of one stereo-isomeric form into another, such as R-ibuprofen to S-ibuprofen?

Isomerization or enantiomerization

What is the process called when isomerization results in the change of configuration at a single chiral center?

Epimerization

What term is used when isomerization leads to the formation of racemates?

Racemization

What are the advantages of single enantiomers over racemic mixtures in terms of pharmacodynamic profile?

Single enantiomers have less complex and more selective pharmacodynamic profile, leading to lesser adverse drug reactions, improved therapeutic profile, and less chances of drug interactions. Signup and view all the answers

Why are single enantiomers considered advantageous in terms of drug exposure and metabolic load on the body?

Patients are exposed to less amount of drug with single enantiomers, resulting in the body being exposed to lesser metabolic, renal, and hepatic load of the drug. Signup and view all the answers

What is the significance of producing antibiotics with only one enantiomer?

Many antibiotics are produced with only one enantiomer to ensure purity and effectiveness, especially since they are often made by fermentation processes. Signup and view all the answers

Why is it easier to monitor the therapeutic levels of single enantiomer drugs?

Therapeutic drug monitoring of single enantiomers is easier due to the presence of only one active form, making it simpler to assess and adjust dosages. Signup and view all the answers

What is the trend in the pharmaceutical industry regarding the development of single enantiomer drugs?

Many single enantiomer drugs are being developed and tested in clinical trials to compare their efficacy and safety with racemic mixtures. Signup and view all the answers

How do single enantiomers contribute to improving the therapeutic and safety profile of drugs?

Single enantiomers offer improved therapeutic profiles, reduced adverse drug reactions, and lower chances of drug interactions compared to racemic mixtures. Signup and view all the answers
