Gimoti Drug Information

Important

Administration and Storage Instructions One spray in one nostril administers the appropriate dose. Before administering the first dose from a bottle, prime the pump by pressing down on the finger flange and releasing 10 sprays in the air. Place the spray nozzle tip under one nostril and lean the head slightly forward so the tip of spray nozzle is aimed away from the septum and toward the back of the nose.

Close the other nostril with the other index finger. Move spray pump upwards so the tip of the nozzle is in the nostril. To ensure a full dose, hold the bottle upright while pressing down firmly and completely on finger flange and release while inhaling slowly through the open nostril.

Remove spray pump nozzle tip from nostril and exhale slowly through the mouth. Wipe the spray nozzle with a clean tissue. Missed or Incomplete Doses If uncertain that the spray entered the nose, do not repeat the dose.

Take the next dose at the scheduled time. If a dose is missed, take the next dose of GIMOTI at the regularly scheduled time. Do not make up for the missed dose or double the next dose.

Storage Discard GIMOTI 4 weeks after opening even if the bottle contains unused drug.

Recommended Dosage Adults Less Than 65 Years of Age

The recommended dosage of GIMOTI for the treatment of acute and recurrent diabetic gastroparesis in adults is 1 spray (15 mg) in one nostril, 30 minutes before each meal and at bedtime (maximum of four times daily). Adults 65 Years of Age and Older Elderly patients may be more sensitive to the adverse effects of metoclopramide and require a lower starting dosage . GIMOTI is not recommended in geriatric patients as initial therapy. Geriatric patients receiving an alternative metoclopramide product at a stable dosage of 10 mg four times daily can be switched to GIMOTI 1 spray (15 mg) in one nostril, 30 minutes before each meal and at bedtime (maximum four times daily). Treatment Duration Use GIMOTI for the shortest duration of treatment and periodically reassess the need for continued treatment. Avoid treatment with metoclopramide, including GIMOTI, for longer than 12 weeks.

If longer-term use is unavoidable, routinely monitor for signs and symptoms of TD .

The following adverse reactions are described, or described in greater detail, in other sections of the labeling: Tardive dyskinesia Other extrapyramidal symptoms Neuroleptic malignant syndrome Depression Hypertension Fluid retention Hyperprolactinemia Effects on the ability to drive and operate machinery The following adverse reactions have been identified from clinical studies or postmarketing reports of metoclopramide. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The safety of GIMOTI was evaluated in clinical trials of patients with gastroparesis and established in clinical trials of oral metoclopramide.

Most common adverse reactions (≥5%) are: dysgeusia, headache, and fatigue. To report SUSPECTED ADVERSE REACTIONS, contact Evoke Pharma, Inc. at 1-833-4-GIMOTI (1-833-444-6684), or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. Safety of GIMOTI In a randomized, placebo-controlled clinical trial of 190 male and female patients of GIMOTI 14 mg, a slightly lower than recommended dosage, administered nasally four times daily for 4 weeks, dysgeusia was the most commonly reported adverse reaction (15% of GIMOTI-treated patients and 4% of placebo-treated patients). Other adverse reactions were similar to those reported for oral metoclopramide.

Safety of Oral Metoclopramide The most common adverse reactions (in approximately 10% of patients receiving the recommended oral metoclopramide dosage of 10 mg four times daily) were restlessness, drowsiness, fatigue, and lassitude. In general, the incidence of adverse reactions correlated with the dosage and duration of metoclopramide administration. Adverse reactions, especially those involving the nervous system, occurred after stopping metoclopramide including dizziness, nervousness, and headaches.

Central Nervous System Disorders Tardive dyskinesia, acute dystonic reactions, drug-induced parkinsonism, akathisia, and other extrapyramidal symptoms Convulsive seizures Hallucinations Restlessness, drowsiness, fatigue, and lassitude occurred in approximately 10% of patients who received metoclopramide orally 10 mg four times daily. Insomnia, headache, confusion, dizziness, or depression with suicidal ideation occurred less frequently. Neuroleptic malignant syndrome, serotonin syndrome (in combination with serotonergic agents) Endocrine Disorders : Fluid retention secondary to transient elevation of aldosterone, galactorrhea, amenorrhea, gynecomastia, impotence secondary to hyperprolactinemia Cardiovascular Disorders : Acute congestive heart failure, possible atrioventricular block, hypotension, hypertension, supraventricular tachycardia, bradycardia, fluid retention Gastrointestinal Disorders : Nausea, bowel disturbances (primarily diarrhea) Hepatic Disorders : Hepatotoxicity, characterized by, e.g., jaundice and altered liver function tests, when metoclopramide was administered with other drugs with known hepatotoxic potential Renal and Urinary Disorders : Urinary frequency, urinary incontinence Hematologic Disorders : Agranulocytosis, neutropenia, leukopenia, methemoglobinemia, sulfhemoglobinemia Hypersensitivity Reactions : Bronchospasm (especially in patients with a history of asthma), urticaria, rash, angioedema, including glossal or laryngeal edema Eye Disorders : Visual disturbances Metabolism Disorders : Porphyria

Effects of Other Drugs on Metoclopramide Table 1 displays the effects of

other drugs on metoclopramide. Table 1. Effects of Other Drugs on Metoclopramide Antipsychotics Clinical Impact Potential for additive effects, including increased frequency and severity of tardive dyskinesia (TD), other extrapyramidal symptoms (EPS), and neuroleptic malignant syndrome (NMS). Intervention Avoid concomitant use. Strong CYP2D6 Inhibitors, not Included in Antipsychotic Category Above Clinical Impact Increased plasma concentrations of metoclopramide; risk of exacerbation of extrapyramidal symptoms.

Intervention Use of GIMOTI is not recommended . Examples quinidine, bupropion, fluoxetine, and paroxetine Monoamine Oxidase Inhibitors Clinical Impact Increased risk of hypertension. Intervention Avoid concomitant use. Central Nervous System (CNS) Depressants Clinical Impact Increased risk of CNS depression.

Intervention Avoid GIMOTI or the interacting drug, depending on the importance of the drug to the patient. Examples alcohol, sedatives, hypnotics, opiates, and anxiolytics Drugs that Impair Gastrointestinal Motility Clinical Impact Potential for decreased effect of metoclopramide due to opposing effects on gastrointestinal motility. Intervention Monitor for reduced effect on gastrointestinal motility.

Examples antiperistaltic antidiarrheal drugs, anticholinergic drugs, and opiates Dopaminergic Agonists and Other Drugs that Increase Dopamine Concentrations Clinical Impact Decreased therapeutic effect of metoclopramide due to opposing effects on dopamine. Intervention Monitor for reduced therapeutic effect. Examples apomorphine, bromocriptine, cabergoline, levodopa, pramipexole, ropinirole, and rotigotine

Effects of Metoclopramide on Other Drugs Table 2 displays the effects of

metoclopramide on other drugs. Table 2. Effects of Metoclopramide on Other Drugs Dopaminergic Agonists and Drugs Increasing Dopamine Concentrations Clinical Impact Opposing effects of metoclopramide and the interacting drug on dopamine. Potential exacerbation of symptoms (e.g., parkinsonian symptoms). Intervention Avoid concomitant use . Examples Apomorphine, bromocriptine, cabergoline, levodopa, pramipexole, ropinirole, rotigotine Succinylcholine, Mivacurium Clinical Impact Metoclopramide inhibits plasma cholinesterase leading to enhanced neuromuscular blockade.

Intervention Monitor for signs and symptoms of prolonged neuromuscular blockade Drugs with Absorption Altered due to Increased Gastrointestinal Motility Clinical Impact The effect of metoclopramide on other drugs is variable. Increased gastrointestinal (GI) motility by metoclopramide may impact absorption of other drugs leading to decreased or increased drug exposure. Intervention Drugs with Decreased Absorption (e.g., digoxin, atovaquone, posaconazole oral suspension Interaction does not apply to posaconazole delayed-release tablet., fosfomycin) : Monitor for reduced therapeutic effect of the interacting drug.

For digoxin, monitor therapeutic drug concentrations and increase the digoxin dose as needed (see prescribing information for digoxin). Drugs with Increased Absorption (e.g., sirolimus, tacrolimus, cyclosporine) : Monitor therapeutic drug concentrations and adjust the dose as needed. See prescribing information for the interacting drug. Insulin Clinical Impact Increased GI motility by metoclopramide may increase delivery of food to the intestines and increase blood glucose.

Intervention Monitor blood glucose and adjust insulin dosage regimen as needed.

Pregnancy Risk Summary Published studies, including retrospective cohort studies, national registry studies, and meta-analyses, do not report a consistent pattern or a consistently increased risk of adverse pregnancy-related outcomes with oral use of metoclopramide during pregnancy. However, available data from a case report of GIMOTI use in pregnancy is insufficient to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. There are potential risks to the neonate following exposure in utero to metoclopramide during delivery (see Clinical Considerations ). In animal reproduction studies, no adverse developmental effects were observed with oral administration of metoclopramide to pregnant rats and rabbits at exposures about 6 and 12 times the maximum recommended human dose (MRHD) (see Data ). The background risk of major birth defects and miscarriage for the indicated population is unknown.

All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Metoclopramide crosses the placental barrier and may cause extrapyramidal signs and methemoglobinemia in neonates with maternal administration during delivery.

Monitor neonates for extrapyramidal signs . Data Animal Data Reproduction studies have been performed following administration of oral metoclopramide during organogenesis in pregnant rats at about 6 times the MRHD calculated on body surface area and in pregnant rabbits at about 12 times the MRHD calculated on body surface area. No evidence of adverse developmental effects due to metoclopramide was observed.

Pediatric Use Metoclopramide is not recommended for use in pediatric patients due to the risk of tardive dyskinesia (TD) and other extrapyramidal symptoms as well as the risk of methemoglobinemia in neonates. The safety and effectiveness of GIMOTI in pediatric patients have not been established. Dystonias and other extrapyramidal symptoms associated with metoclopramide are more common in pediatric patients than in adults . In addition, neonates have reduced levels of NADH-cytochrome b 5 reductase, making them more susceptible to methemoglobinemia, a possible adverse reaction of metoclopramide use in neonates .

is contraindicated: In patients with a history of tardive dyskinesia (TD) or a dystonic reaction to metoclopramide . When stimulation of gastrointestinal motility might be dangerous (e.g., in the presence of gastrointestinal hemorrhage, mechanical obstruction, or perforation). In patients with pheochromocytoma or other catecholamine-releasing paragangliomas. Metoclopramide may cause a hypertensive/pheochromocytoma crisis, probably due to release of catecholamines from the tumor . In patients with epilepsy. Metoclopramide may increase the frequency and severity of seizures . In patients with hypersensitivity to metoclopramide.

Reactions have included laryngeal and glossal angioedema and bronchospasm . History of TD or dystonic reaction to metoclopramide When stimulation of gastrointestinal motility might be dangerous Pheochromocytoma, catecholamine-releasing paragangliomas Epilepsy Hypersensitivity to metoclopramide

Manifestations of metoclopramide overdosage included drowsiness, disorientation, extrapyramidal reactions, other adverse reactions associated with metoclopramide use (including, e.g., methemoglobinemia), and sometimes death. Neuroleptic malignant syndrome (NMS) has been reported in association with metoclopramide overdose and concomitant treatment with another drug associated with NMS. There are no specific antidotes for metoclopramide overdosage. If over-exposure occurs, call your Poison Control Center at 1-800-222-1222 for current information on the management of poisoning or overdosage.

Methemoglobinemia can be reversed by the intravenous administration of methylene blue. However, methylene blue may cause hemolytic anemia in patients with G6PD deficiency, which may be fatal. Hemodialysis and continuous ambulatory peritoneal dialysis do not remove significant amounts of metoclopramide.
