Nitrofurantoin cannot be used to treat infections other than simple cystitis. At the concentrations achieved in urine (>100 μg/mL), nitrofurantoin is a bactericide. It is bacteriostatic against most susceptible organisms at concentrations less than 32 μg/mL. [9] Nitrofurantoin and the quinolone antibiotics are mutually antagonistic in vitro ...
Nearly all quinolone antibiotics in use are fluoroquinolones, which contain a fluorine atom in their chemical structure and are effective against both Gram-negative and Gram-positive bacteria. One example is ciprofloxacin , one of the most widely used antibiotics worldwide.
Among the fluoroquinolones, ciprofloxacin and levofloxacin are used more frequently for the treatment of UTIs. These agents are well-absorbed orally and achieve significant concentrations in urine and various tissues. [12] However, fluoroquinolones administration carries risk of GI symptoms, confusion, hypersensitivity, tendinopathy, and ...

Furaltadone — an antiprotozoal; Furazidine — an antibacterial and antiprotozoal Furaginum — an antibacterial; Furylfuramide — a formerly used food preservative
Quinolones/Fluoroquinolones Ciprofloxacin: Cipro, Ciproxin, Ciprobay: Urinary tract infections, bacterial prostatitis, community-acquired pneumonia, bacterial diarrhea, mycoplasmal infections, gonorrhea: Nausea (rare), irreversible damage to central nervous system (uncommon), tendinosis (rare)
Also bactericidal are daptomycin, fluoroquinolones, metronidazole, nitrofurantoin, co-trimoxazole, telithromycin. Aminoglycosidic antibiotics are usually considered bactericidal, although they may be bacteriostatic with some organisms.

Antifolates act primarily as inhibitors of both RNA and DNA, and are often grouped with nucleic acid inhibitors in textbooks. However, they also act indirectly as protein synthesis inhibitors (because tetrahydrofolate is also involved in the synthesis of amino acids serine and methionine), so they are sometimes considered as their own category, antimetabolites.
