What is Weiperan?

Weiperan is used to treat the symptoms of a certain type of stomach problem called gastroparesis in patients with diabetes. It works by increasing the movements or contractions of the stomach and intestines. It relieves symptoms such as nausea, vomiting, heartburn, a feeling of fullness after meals, and loss of appetite. Weiperan is also used to treat heartburn for patients with gastroesophageal reflux disease (GERD). GERD is esophageal irritation from the backward flow of gastric acid into the esophagus.

Weiperan is available only with your doctor's prescription.

Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, Weiperan is used in certain patients with the following medical conditions:

Weiperan indications

An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

Weiperan increases muscle contractions in the upper digestive tract. This speeds up the rate at which the stomach empties into the intestines.

Weiperan is used short-term to treat heartburn caused by gastroesophageal reflux in people who have used other medications without relief of symptoms.

Weiperan is also used to treat slow gastric emptying in people with diabetes (also called diabetic gastroparesis), which can cause nausea, vomiting, heartburn, loss of appetite, and a feeling of fullness after meals.

How should I use Weiperan?

Follow the directions on your prescription label and read all medication guides. Use the medicine exactly as directed.

A Weiperan injection is given into a muscle or as an infusion into a vein. A healthcare provider will give the injection, usually during surgery, chemotherapy, or a medical procedure.

Weiperan oral is taken for only 4 to 12 weeks.

NEVER USE Weiperan IN LARGER AMOUNTS THAN RECOMMENDED, OR FOR LONGER THAN 12 WEEKS. High doses or long-term use of Weiperan can cause a serious movement disorder that may not be reversible. The longer you use Weiperan, the more likely you are to develop this movement disorder. The risk of this side effect is higher in diabetics and older adults (especially women).

Weiperan is usually taken 30 minutes before meals and at bedtime, or only with meals that usually cause heartburn. Follow your doctor's dosing instructions very carefully.

Do not use two different forms of Weiperan (such as tablets and oral syrup) at the same time.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

To take the orally disintegrating tablet (ODT):

Store at room temperature in a tightly-closed container, away from moisture and heat. Keep the bottle tightly closed.

After you stop taking Weiperan, you may have unpleasant withdrawal symptoms such as headache, dizziness, or nervousness.

Uses of Weiperan in details

There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.

How to use Weiperan injection

Weiperan description

Each ampoule of injection contains anhydrous Weiperan (as Weiperan) 10 mg in 2 mL and sodium chloride in water for injections. When necessary, pH is adjusted with sodium hydroxide and/or hydrochloric acid.

Weiperan is 4-amino-5-chloro-N-(2-diethylaminoethyl)-2-methoxybenzamide HCl monohydrate. It has a molecular weight of 354.3 and its molecular formula is C14H22ClN3O2·HCl·H2O.

Weiperan hydrochloride occurs as a white or almost white, crystalline powder or crystals, very soluble in water, freely soluble in alcohol, sparingly soluble in methylene chloride, practically insoluble in ether.

During the earliest manifestations of diabetic gastric stasis, oral administration may be initiated. If severe symptoms are present, therapy should begin with IM or IV administration for up to 10 days until symptoms subside at which time the patient can be switched to oral therapy. Since diabetic gastric stasis is often recurrent, therapy should be reinstituted at the earliest manifestation.
