Zantac (Ranitidine)

Droga Usi

Zantac is used for treating certain conditions that cause your body to make too much stomach acid (e.g., Zollinger-Ellison syndrome). It is also used to treat ulcers of the small intestine that have not responded to other treatment. It may also be used for other conditions as determined by your doctor.

Come utilizzare

Use Zantacas directed by your doctor.

• Zantac may be taken by mouth with or without food.
• Swallow Zantac whole. Do not crush or chew before swallowing.
• Continue to take Zantac even if you feel well. Do not miss any doses. Taking Zantac at the same time each day will help you to remember to take it.

Classe di Droga e il Meccanismo

Zantac is an H2 receptor blocker. It works by blocking the action of histamine in the stomach. This reduces the amount of acid the stomach makes. Reducing stomach acid helps to reduce heartburn, to heal irritation of the esophagus, and to heal ulcers of the stomach or intestines.

Dose

If you miss a dose of Zantac , use it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.

Immagazzinaggio

Store Zantac between 59 and 77 degrees F (15 and 25 degrees C). Store away from heat, moisture, and light. Do not store in the bathroom. Keep Zantac out of the reach of children and away from pets.
