From Lab to Life: The Journey of Life-Saving Medications

The combination of gefitinib and capecitabine was well tolerated and showed clinical activity in advanced solid tumors, including colorectal, breast, non-small-cell lung cancer (NSCLC), and pancreatic cancer. [18F]fluorodeoxyglucose positron emission tomography uptake was correlated with response. Sequential rather than concomitant dosing led to a lower incidence of hematologic toxicity. One patient with cholangiocarcinoma achieved a confirmed partial response to this regimen.

Lenalidomide
Lenalidomide manufacturer is used alone or in combination with dexamethasone to treat multiple myeloma (a type of cancer of the bone marrow) in adults who are not eligible for a stem cell transplant. It is also used to treat anemia in people with rare blood and bone marrow disorders (myelodysplastic syndromes).

This medication slows the growth of cancer cells. It can lower your white blood cell count, which may increase your risk of infections, and it can decrease platelet counts, which may increase your chance of bleeding. It is a very powerful drug that can cause serious side effects, including heart problems, kidney failure, and nervous system problems.

It is important to tell your doctor if you are experiencing any of these side effects. Your doctor will monitor you closely for any unusual symptoms and may change your dose or stop your treatment if necessary.

Some people who take this medication develop a severe reaction that affects the whole body and can be fatal. If you experience these symptoms, get emergency medical help right away. These symptoms include fever, swollen glands, flu-like symptoms with a rash, blistering of the skin or eyes, and rapid or shallow breathing.

Your doctor will check your blood regularly while you are taking this medication. A nurse or person trained to take blood (phlebotomist) will draw your blood before you start the medication and at regular intervals during treatment.

It is important to avoid pregnancy while taking this medication. It is absorbed through the skin and lungs and can harm an unborn baby. Your doctor will give you information about avoiding pregnancy and will ask you to sign a consent form. You should use a proven method of birth control, such as birth control pills or a condom, and practice abstinence. You should also have a negative pregnancy test before starting this medication and have regular pregnancy tests during your treatment, as well as 4 weeks after you finish the drug.

This medication can interact with certain other medications, such as erythropoietin-stimulating agents and estrogens. It can also increase your blood levels of digoxin, which can be harmful to your heart.

Gefitinib
Gefitinib is an anti-cancer agent that binds tightly to the EGFR tyrosine kinase and blocks its activation. This drug inhibits a specific mutation that is frequently found in some types of non-small cell lung cancer (NSCLC) and causes the tumour to grow more slowly. In patients with a EGFR mutation, gefitinib has been shown to improve outcomes in comparison with standard chemotherapy.

The clinical development of gefitinib was driven by advances in the scientific understanding of the drug’s target biology and identification of potential biomarkers of response. The results of early trials in unselected NSCLC populations indicated that a subgroup of patients had high response rates and the IPASS study further demonstrated that gefitinib improved progression-free survival (PFS) in comparison to carboplatin/paclitaxel as first-line therapy in patients with EGFR mutation positive tumours.

EGFR mutations occur in NSCLC and can be identified by a variety of tests. Once these are known, clinicians can select the most suitable patients to receive treatment with a tyrosine kinase inhibitor. gefitinib manufacturers india has been shown to work best in patients with a mutation in the EGFR gene and a specific form of NSCLC, called brochoalveolar adenocarcinoma. It has also been shown to benefit patients who have a low EGFR protein expression level.

Gefitinib is taken once a day and can be taken with or without food. It is important to take it exactly as prescribed by your doctor. You may need blood tests before and during treatment to check your levels of certain blood cells. Your doctor will monitor your progress and adjust the dose of your medicine if necessary.

Side effects of gefitinib are generally mild to moderate and depend on the dosage you are given and your other treatments. Common ones include a rash, diarrhoea and mouth ulcers. If you have problems with your vision, tell your doctor immediately.

Rare but serious side effects of gefitinib include a lung problem that is sometimes fatal, called pulmonary toxicity or ill-defined interstitial pneumonia with eosinophilia (PILIE). This occurs in patients who have a genetic predisposition to develop the disorder and those with a history of smoking and/or preexisting fibrotic conditions of the lungs, particularly idiopathic pulmonary fibrosis.

Capecitabine
Capecitabine is a cancer medicine that works by stopping the growth of cancer cells. It belongs to a group of medicines called antineoplastics (cancer medicines). Capecitabine can be used alone or with other cancer treatments. It may help to improve the chances of a cure for some types of cancer.

It is taken by mouth and breaks down in the body to fluorouracil (5-FU), which kills cancer cells. It is used to treat colorectal cancer, breast cancer, esophageal cancer and pancreatic cancer. It is also being studied in the treatment of other types of cancer. It is known by the brand name Xeloda.

When capecitabine drug manufacturer is used in combination with other cancer treatments, it may help to improve the chance of a cure for some types of cancer. It is often given with other chemotherapy drugs such as fluorouracil, oxaliplatin and gemcitabine. It is important that patients take this medication exactly as prescribed by their doctor.

This drug may cause diarrhoea (loose stools). If it is severe, tell your doctor. They may prescribe you with special anti-diarrhoea medicines to take at home. It can also cause low blood cell levels (anaemia). This can make you feel very tired and have pale skin. If this happens, contact your doctor straight away on the hospital 24-hour number. They can give you a drip to give you extra red blood cells.

You may notice that your mouth becomes sore and has ulcers while you are having this treatment. You should drink plenty of fluids and clean your teeth often with a soft toothbrush. You can also use special mouthwashes to reduce this side effect.

Capecitabine can also affect the palms and soles of your feet (hand-foot syndrome). If this occurs, avoid heat and increased pressure on your hands and feet. Your doctor can recommend creams and medications to help with this.

Plasma
Plasma is the fluid in the blood that holds red and white blood cells. Some illnesses can cause problems with the plasma. During therapeutic plasma exchange, also known as PLEX, or plasma exchange therapy, the harmful plasma is removed and replaced with healthy plasma. This procedure can help treat autoimmune [aw-tuh-REE-sun] diseases. Your child might need multiple treatments, called sessions or rounds, to get the right results.

Plasmapheresis is done through a needle or catheter that is placed in a large vein in the neck or chest, called the central line. It may be connected to a machine that separates the blood into its components, including plasma and blood cells. The machine treats the plasma outside the body to remove the parts that are causing your child’s disease, such as antibodies or other abnormal proteins. The healthy plasma is returned to your child.

During the procedure, your child will lie in bed or sit in a recliner. They will be monitored by a team of doctors, nurses and Child Life staff who are experts in apheresis procedures. They will talk to your child about their treatment and comfort level throughout the process.

The blood is withdrawn through a needle in each arm, or sometimes through a tube called a central venous catheter (or CVC) in the neck or chest that leads to a large vein near the heart. Sometimes minor surgery is needed to place this tube in the large vein in the neck, called the jugular vein. The tubes for both the needles or CVC are connected to a larger machine.

After the plasma is removed from the body, it will be replaced with donor plasma or a combination of plasma and albumin solution. The replacement solution is mixed in with a short-acting anticoagulant, such as citrate, to prevent blood clots from forming in the vein.

Plasmapheresis is a safe, effective way to treat many conditions that affect your child’s immune system, including rheumatic diseases such as vasculitis, lupus, or antiphospholipid antibody syndrome (APS). It can also be used to treat some neurological disorders like Guillain-Barre syndrome, myasthenia gravis and Lambert-Eaton myasthenic syndrome; and multiple sclerosis.
