What is Grandem Inj?

Grandem Inj injection is used to prevent nausea and vomiting that may occur after treatment with cancer medicines (chemotherapy or radiation), including high-dose cisplatin. Grandem Inj is also used to prevent and treat nausea and vomiting that may happen after surgery.

Grandem Inj is a selective 5-HT3 receptor antagonist. It works in the stomach to block the signals to the brain that cause nausea and vomiting.

Grandem Inj is to be given only by or under the immediate supervision of your doctor.

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 this use is not included in product labeling, Grandem Inj injection is used in certain patients:

• To prevent the nausea and vomiting that may occur after cancer radiation treatment in patients undergoing bone marrow transplantation.

Grandem Inj indications

Grandem Inj Injection is a serotonin-3 (5-HT3) receptor antagonist indicated for:

• The prevention of nausea and/or vomiting associated with initial and repeat courses of emetogenic cancer therapy, including high-dose cisplatin.
• The prevention and treatment of postoperative nausea and vomiting in adults. As with other antiemetics, routine prophylaxis is not recommended in patients in whom there is little expectation that nausea and/or vomiting will occur postoperatively. In patients where nausea and/or vomiting must be avoided during the postoperative period, Grandem Inj Injection is recommended even where the incidence of postoperative nausea and/or vomiting is low.

How should I use Grandem Inj?

Use Grandem Inj as directed by your doctor. Check the label on the medicine for exact dosing instructions.

• An extra patient leaflet is available with Grandem Inj. Talk to your pharmacist if you have questions about this information.
• Apply Grandem Inj 24 to 48 hours before your chemotherapy treatment, or as directed by your doctor.
• Grandem Inj should be applied to clean, healthy skin on the upper arm. Do not apply to cut, scraped, or irritated skin. Do not use creams, oils, lotions, powders, or any other products that could irritate the skin or prevent the patch from sticking well.
• To apply Grandem Inj, remove the patch from the sealed pouch. Do not cut or damage the patch. Remove the thin, clear, protective liner. Bend the patch in the middle and remove one-half of the rigid plastic film. Apply the exposed, sticky area of the patch to your skin. Remove the other half of the rigid plastic film and press the whole patch firmly in place against the skin.
• If the patch does not stick well, you may tape the edges with surgical bandages or medical adhesive tape. Do not completely cover the patch with bandages or tape. Do not wrap completely around your arm. Ask your health care provider if you are unsure of what type of dressing you can use.
• Wash your hands immediately after using Grandem Inj.
• You may shower or bathe normally while wearing the patch. You should avoid activities such as swimming, strenuous exercise, or using a sauna or whirlpool. It is unknown how these activities may affect Grandem Inj.
• Continue to wear the patch during your chemotherapy and for at least 24 hours after your treatment is completed. Grandem Inj may be worn for up to 7 days or as directed by your doctor.
• To remove the patch, gently peel it off of your skin and fold the sticky side together. Throw the used patch in the trash away from children and pets. Wash your hands after handling the patch.
• Gently wash the skin with soap and water where the patch was applied.
• If you miss a dose of Grandem Inj, contact your doctor immediately.

Ask your health care provider any questions you may have about how to use Grandem Inj.

Grandem Inj interactions

What other drugs will affect Grandem Inj?

Grandem Inj does not induce or inhibit the cytochrome P-450 drug-metabolizing enzyme system in vitro. There have been no definitive drug-drug interaction studies to examine pharmacokinetic or pharmacodynamic interaction with other drugs; however, in humans, Grandem Inj (Grandem Inj) Injection has been safely administered with drugs representing benzodiazepines, neuroleptics, and anti-ulcer medications commonly prescribed with antiemetic treatments. Grandem Inj (Grandem Inj) Injection also does not appear to interact with emetogenic cancer chemotherapies. Because Grandem Inj is metabolized by hepatic cytochrome P-450 drug-metabolizing enzymes, inducers or inhibitors of these enzymes may change the clearance and, hence, the half-life of Grandem Inj. No specific interaction studies have been conducted in anesthetized patients. In addition, the activity of the cytochrome P-450 subfamily 3A4 (involved in the metabolism of some of the main narcotic analgesic agents) is not modified by Grandem Inj (Grandem Inj) in vitro.

In in vitro human microsomal studies, ketoconazole inhibited ring oxidation of Grandem Inj (Grandem Inj). However, the clinical significance of in vivo pharmacokinetic interactions with ketoconazole is not known. In a human pharmacokinetic study, hepatic enzyme induction with phenobarbital resulted in a 25% increase in total plasma clearance of intravenous Grandem Inj (Grandem Inj). The clinical significance of this change is not known.

QT prolongation has been reported with Grandem Inj (Grandem Inj). Use of Grandem Inj (Grandem Inj) in patients concurrently treated with drugs known to prolong the QT interval and/or are arrhythmogenic, this may result in clinical consequences.

Chemotherapy-Induced Nausea and Vomiting

Over 3700 patients have received Grandem Inj (Grandem Inj) Tablets in clinical trials with emetogenic cancer therapies consisting primarily of cyclophosphamide or cisplatin regimens.

In patients receiving Grandem Inj (Grandem Inj) Tablets 1 mg bid for 1, 7 or 14 days, or 2 mg daily for 1 day, adverse experiences reported in more than 5% of the patients with comparator and placebo incidences are listed in Table 4.

Table 4 Principal Adverse Events in Clinical Trials Metoclopramide/dexamethasone and phenothiazines/dexamethasone

In the absence of a placebo group, there is uncertainty as to how many of these events should be attributed to Grandem Inj (Grandem Inj), except for headache, which was clearly more frequent than in comparison groups.
