What is Cefadroxil and explain in detail?
Cefadroxil (formerly trademarked as Duricef) is a broad-spectrum antibiotic of the cephalosporin type, effective in Gram-positive and Gram-negative bacterial infections.  It is a bactericidal antibiotic.
It was patented in 1967 and approved for medical use in 1978.

Medical use
Cefadroxil is a first-generation cephalosporin antibacterial drug that is the para-hydroxy derivative of cephalexin, and is used similarly in the treatment of mild to moderate susceptible infections such as the bacterium Streptococcus pyogenes, causing the disease popularly called strep throat or streptococcal tonsillitis, urinary tract infection, reproductive tract infection, and skin infections.
Cefadroxil is used as an antibiotic prophylaxis before dental procedures, for patients allergic to penicillins.

Spectrum of bacterial resistance and susceptibility
Cefadroxil has a broad spectrum of activity and has been effective in treating bacteria responsible for causing tonsillitis, and infections of the skin and urinary tract. Cefadroxil covers similar organisms to Cephalexin given that it is a derivative drug. The following represents MIC susceptibility data for a few medically significant microorganisms.
Escherichia coli: 8 μg/ml
Staphylococcus aureus: 1 – 2 μg/ml
Streptococcus pneumoniae: ≤1  – >16 μg/ml

Side effects
The most common side effects of cefadroxil are diarrhea (which, less commonly, may be bloody), nausea, upset stomach, and vomiting. Other side effects includerashes, hives, and itching.

Pharmacokinetics
Cefadroxil is almost completely absorbed from the gastrointestinal tract
