Safely Buy Tarceva (Erlotinib) from Canada Prescriptions Plus.

Description

Tarceva is the Brand name of Erlotinib, a medicine used to treat NSCLC Non-Small Cell Lung Cancer and Pancreatic Cancer. It is known as a Tyrosine Kinase Inhibitor TKI that works to help these conditions by blocking the proteins in cancer cells that trigger the growth, multiplication, and spreading. NSCLC is malignant, it forms in the lungs that causes difficulty in breathing and health complications while pancreatic cancer forms in the pancreas which is usually hard to identify at its early stage due to unnoticeable signs. This medication is considered an advanced treatment for pancreatic cancer and is usually prescribed to patients who cannot remove cancer surgically and have not been in chemotherapy.  

Tarceva effectiveness has been proven for some patients and is said to improve survival rates in the early stage. It appears to be better than chemotherapy for there is no reoccurrence of cancer. This medicine can be monotherapy or can be prescribed together with other medicine like gemcitabine for pancreatic cancer.  

Tarceva Mechanism of Action 

Tarceva inhibits the intracellular phosphorylation of tyrosine kinase associated with Epidermal Growth Factor Receptor EGFR. Tyrosine Kinase is responsible for the activation of signals and messages received by the cells, this medication works by interfering with those signals by attaching to EFGR and blocking the action. This medicine is known as a targeted therapy because it locates and directly targets cancer cells and does not affect healthy and normal cells. They find and attack cancer cells in specific areas to block certain messages. Since cells are everywhere in the body they have a basis for their attack, it is when a cell has too much protein, if there is a mutation and DNA changes it means they are not a normal cell.  

Aside from blocking and turning off the signals it also changes the protein of cancer cells to die, they stop making new blood vessels in the area to feed on the cancer cells and carry toxins to kill except the normal cells. This medication may stop the growth of cancer or shrink it.  

Is Tarceva Chemotherapy? 

Tarceva is different from Chemotherapy, it is known to be a therapy drug that leaves normal cells alone unlike chemotherapy wherein it is cytotoxic to most cells and damages normal cells in the process of killing cancer cells. Tarceva blocks the message to cancer cells such as to grow and mutate and may also send a signal to destroy itself. This medicine is considered an immune therapy for it boosts the immune system.
