Treatment Summary
Cimetidine is a drug that blocks histamine from binding to histamine H2 receptors and reduces the production of stomach acid. It can also inhibit the activity of enzymes to help prevent the growth of some types of cancer cells. Cimetidine is commonly used to treat conditions such as ulcers and acid reflux, and is sometimes used in neoadjuvant therapy.

Effectiveness
How Cimetidine Affects Patients
Cimetidine works by blocking histamine receptors in the stomach, reducing the amount of stomach acid that is produced. It is used to treat stomach and intestinal ulcers, heartburn, and other digestive issues. It also affects the way certain enzymes in the liver work, and can increase the number of bacteria in the stomach.
How Cimetidine works in the body
Cimetidine works by blocking the histamine receptor on the cells in the stomach. This prevents histamine from having an effect and reduces the production of acid. This leads to a decrease in stomach acid and volume.
When to interrupt dosage
The proposed portion of Cimetidine is based on the diagnosed condition, such as Acid indigestion, Cystic Fibrosis (CF) and Systemic Mastocytosis. The amount of dosage differs, as per the technique of delivery (e.g. Liquid or Intramuscular; Intravenous) specified in the table below.

Patient Q&A Section about cimetidine
These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.
What is a cimetidine used for?
"Cimetidine is a medication that is used to treat ulcers, GERD, and other conditions where the stomach produces too much acid."
Answered by AI
What kind of drug is cimetidine?
"Cimetidine is a prescription medication designed to reduce acidity. It provides relief from heartburn associated with acid indigestion and sour stomach, and can also prevent heartburn from occurring in the first place by limiting exposure to triggering foods and beverages."
Answered by AI
Why was cimetidine taken off the market?
"The FDA has announced that several medicines may contain unsafe levels of N-Nitrosodimethylamine (NDMA), a substance that is classified as a "probable human carcinogen" by the World Health Organization."
Answered by AI
Is cimetidine the same as Zantac?
"Cimetidine and ranitidine are not the same medication, but they are similar. They are both in the same drug class and lower the amount of acid in your stomach. Ranitidine is no longer available in the United States, so cimetidine can be a good replacement option."
