Nationwide Field Promotion Begins for Tuzistra XR, Only 12-Hour Codeine-Based Antitussive, 2-3 Times Longer-Acting than Current 4-6 Times Daily Codeine Antitussives

ENGLEWOOD, CO / ACCESSWIRE / January 15, 2019 / Aytu BioScience, Inc. (NASDAQ: AYTU), a specialty pharmaceutical company focused on global commercialization of novel products addressing significant medical needs, is announcing the field sales launch of Tuzistra® XR, the company’s FDA-approved, 12-hour codeine-based antitussive, which competes in a $3 billion antitussive market with 30-35 million prescriptions written annually.

Tuzistra XR is the only FDA-approved, 12-hour codeine-based antitussive and was exclusively licensed by Aytu from Tris Pharma on November 2, 2018. Tuzistra XR is a novel antitussive consisting of codeine polistirex and chlorpheniramine polistirex in a patented 12-hour, extended-release oral suspension. Current codeine-based antitussives are dosed every four to six hours.

Josh Disbrow, Aytu BioScience’s Chief Executive Officer commented, “We have ramped up promotional efforts with our nationwide sales force, and the team is promoting Tuzistra XR to our targeted primary care physicians and other high prescribing customers, just as the annual cough and cold season gets underway.”

Mr. Disbrow continued, “So far this season, up to 7.3 million Americans have had influenza, so we’re pleased to be able to provide physicians and patients with an effective, longer-acting cough suppressant to help combat the symptoms often accompanying the flu and other respiratory illnesses. Back in December, we prepared the market by stocking wholesalers and pharmacies and, with the distribution channel now stocked nationwide, we’re excited to scale up our Tuzistra XR promotional efforts.”

The company’s scale up of field promotion aligns with the start of the flu season, which has just gotten underway. According to the CDC, as of January 11, 2019, it is estimated that up to 7.3 million people have been sick with influenza this season. There have been widespread flu outbreaks in 31 states. This is the CDC’s first such estimate for the 2018-2019 influenza season. Influenza activity is a key proxy for cough and upper respiratory symptom activity and aligns with antitussive prescribing.



TUZISTRA XR is a combination of codeine, an opiate agonist antitussive, and chlorpheniramine, a histamine-1 (H1) receptor antagonist indicated for relief of cough and symptoms associated with upper respiratory allergies or a common cold.

Limitation of Use: Not indicated for pediatric patients under 18 years of age.




Ultra-Rapid Metabolism

Respiratory depression and death have occurred in children who received codeine following tonsillectomy and/or adenoidectomy and had evidence of being ultra-rapid metabolizers of codeine due to a CYP2D6 polymorphism.

Concomitant Use with Benzodiazepines, CNS Depressants

Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Avoid use of opioid cough medications in patients taking benzodiazepines, other CNS depressants, or alcohol.


Postoperative pain management of children undergoing tonsillectomy and/or adenoidectomy.

Patients with known hypersensitivity to codeine, chlorpheniramine, or any of the product components of TUZISTRA XR.


Risk of death in individuals who are ultra-rapid metabolizers: Conversion of codeine into its active metabolite, morphine, may occur more rapidly and completely resulting in higher than expected morphine levels and respiratory depression or death. Some individuals CYP2D6 genotype, which prevalence varies widely, and is estimated at 0.5 to 1% in Chinese and Japanese, 0.5 to 1% in Hispanics, 1 to 10% in Caucasians, 3% in African Americans, and 16 to 28% in North Africans, Ethiopians, and Arabs.

Risks from concomitant use with benzodiazepines or other CNS depressants: Concomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death.

Dose-related respiratory depression: Use with caution, including when used postoperatively, in patients with pulmonary disease or shortness of breath, or whenever ventilator function is depressed. Overdose of codeine in adults has been associated with fatal respiratory depression, and the use of codeine in children, have been associated with fatal respiratory depression. If respiratory depression occurs, discontinue the drug and use naloxone hydrochloride or other supportive measures as necessary.

Drug dependence: Prescribe with caution that is appropriate to the use of other opioids.

Head injury and increased intracranial pressure: Avoid in patients with head injury, intra-cranial lesions, or increased intracranial pressure.

Activities requiring mental alertness: Avoid engaging in hazardous tasks requiring complete mental alertness such as driving or operating heavy machinery. Avoid concurrent use of alcohol or other central nervous system depressants.

Obstructive bowel disease: Chronic use of opioids, including codeine, may result in constipation or chronic obstructive bowel disease, especially in patients with underlying intestinal motility disorders.

Acute abdominal conditions: Use with caution in patients with acute abdominal conditions.

Dosing: Measure dose with an accurate milliliter measuring device; a household teaspoon is not accurate and could lead to over dosage, resulting in serious adverse reactions.

Special risk patients: Caution in elderly patients and those with asthma, hypothyroidism, Addison’s disease, prostatic hypertrophy or urethral stricture.


Common adverse reactions of TUZISTRA XR include: nausea and vomiting, constipation, abdominal distension, abdominal pain, blurred vision, diplopia, visual disturbances, confusion, dizziness, depression, drowsiness, sedation, headache, euphoria, facial dyskinesia, feeling faint, light-headedness, general feeling of discomfort or illness, excitability, nervousness, agitation, restlessness, somnolence, insomnia, dyskinesia, irritability, tremor.
