Question 76

Daptomycin is an antibiotic.

Daptomycin is classified as a cyclic lipopeptide antibiotic used to treat certain infections caused by Gram-positive bacteria. It is effective against various strains, including those resistant to other antibiotics.

A) Daptomycin

Daptomycin is an antibiotic specifically designed to combat infections caused by Gram-positive bacteria. It works by disrupting bacterial cell membrane function, making it a critical medication in the treatment of complicated skin and skin structure infections.

B) Acyclovir

Acyclovir is an antiviral medication primarily used to treat infections caused by certain types of viruses, such as herpes. It does not possess antibacterial properties and, therefore, is not classified as an antibiotic.

C) Oxytocin

Oxytocin is a hormone that plays a role in childbirth and lactation. It is not an antibiotic and is used for different therapeutic purposes, such as inducing labor or controlling bleeding after childbirth.

D) Phenazopyridine

Phenazopyridine is a medication that provides relief from urinary tract discomfort but does not have antibacterial effects. It is used as a pain reliever rather than to treat infections, making it non-antibiotic in nature.

Conclusion

Daptomycin is definitively the correct answer as it is the only medication listed that functions as an antibiotic. In contrast, Acyclovir, Oxytocin, and Phenazopyridine serve different medical purposes, such as antiviral therapy and symptom relief, but do not possess antibiotic properties. This distinction underscores the importance of correctly identifying antibiotic medications in clinical practice.
