Cefuroxime axetil, sold under the brand name Ceftin among others, is a second generation oral cephalosporin antibiotic. It is an acetoxyethyl ester prodrug of cefuroxime which is effective orally. The activity depends on in vivo hydrolysis and release of cefuroxime tablets. It was patented in 1976 and approved for medical use in 1987. Medical uses
Second generation cephalosporins are more effective in treating Gram-negative bacilli compared to first generation cephalosporins, which have a greater coverage for Gram-positive cocci. Also, it has been reported that cefuroxime is resistant to hydrolysis by β-lactamases produced by Gram-negative bacteria.Some medical uses are:
Upper respiratory tract infections. Lower respiratory tract infections. Urinary tract infections. Skin and soft tissue infections. Gonorrhoea. Early Lyme disease. Bacterial susceptibility
Cefuroxime axetil treats infections against methicillin, oxacillin and penicillin-sensitive bacterial strains. Cefuroxime axetil does not work against enterococci. Gram-positive aerobic microorganisms

Staphylococcus aureus (Methicillin-sensitive only)
Staphylococcus epidermis
Streptococcus pneumoniae (Penicillin-sensitive only)Gram-negative aerobic microorganisms

Haemophilus influenzae
Moraxella catarrhalis
Neisseria gonorrhoeae
Escherichia coli
Proteus mirabilis
Klebsiella pneumoniae (variable activity)

Mechanism of action
Cefuroxime axetil is a second generation cephalosporin that, like penicillins antibiotics, contains a β-lactam ring structure. Cephalosporins works as a bactericidal antibiotic; that by binding to penicillin-binding proteins (PBPs), inhibit the last step of the bacterial cell wall synthesis. Once the β-lactam ring binds to PBPs, cross-linking between peptidoglycan units is inhibited. Pharmacokinetics
Absorption: Once consumed, cefuroxime axetil is converted to the active compound cefuroxime by esterases of mucosal cells in the gastrointestinal tract. Cefuroxime is then released for systematic circulation.
Trifluridine/tipiracil, sold under the brand name Lonsurf, is a fixed-dose combination medication that is used as a third- or fourth-line treatment of metastatic colorectal cancer or gastric cancer, after chemotherapy and targeted therapeutics have failed. It is a combination of  two active pharmaceutical ingredients: trifluridine, a nucleoside analog, and tipiracil, a thymidine phosphorylase inhibitor. Tipiracil prevents rapid metabolism of trifluridine, increasing the bioavailability of trifluridine.The most common side effects include neutropenia (low levels of neutrophils, a type of white blood cell that fights infection), feeling sick, tiredness and anemia (low red blood cell counts). Medical uses
It is used as a third- or fourth-line treatment for metastatic colorectal cancer or gastric cancer, after chemotherapy and biologic therapy. Contraindications
The combination caused harm to the fetus of pregnant animals, and it was not tested in pregnant women. Pregnant women should not take it, and women should not become pregnant while taking it. Adverse effects
The combination severely suppresses bone marrow function, resulting in fewer red blood cells, white blood cells, and platelets, so many people taking it are at risk for infections, anemia, and blood loss from lack of clotting. It also causes digestive problems, with more than 10% of people experiencing loss of appetite, diarrhea, nausea, and vomiting. More than 10% of people experience fatigue and fever.Between 1 and 10% of people have skin and mucosa issues, like rashes and itchiness, or mouth sores, as well as skin sloughing, numbness, redness, and swelling of their palms and soles. Dizziness and confusion are common as well.
