Tykerb 250mg Tablet is an anti-cancer medication. It works against the HER2 (human epidermal growth factor receptor protein) receptors and EGFRs (epidermal growth factor receptor) which are responsible for the over-proliferation of cells. This is how it inhibits the growth of cancerous cells causing downstream signaling pathways.
Pharmacokinetic data from these studies indicated that serum lapatinib concentrations peak 4 hours after dosing, increase with increasing dose, accumulate approximately two-fold with daily dosing, and achieve steady state in 6 to 7 days, suggesting an effective half-life of 24 hours.
Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
