Final answer:
Cubicin is an antibiotic used to treat bacterial infections with once-daily administration, while Cubicin RF is a formulation for patients with renal impairment, allowing for less frequent dosing.
Step-by-step explanation:
The difference between Cubicin and Cubicin RF lies in their formulation and usage. Cubicin (daptomycin) is an antibiotic used to treat certain infections caused by bacteria, particularly skin infections and bloodstream infections including endocarditis. It is typically administered once daily.
On the other hand, Cubicin RF, where RF stands for 'Renal Failure', is a reduced-frequency formulation specifically designed for patients with renal impairment. It is provided in a dosage that allows for less frequent administration appropriate for patients whose kidneys are not functioning properly.
