The Sri Lankan phenobarbital market is expected to grow steadily, supported by increasing neurological disorder prevalence and healthcare system improvements. Government initiatives to expand access to essential medicines and ongoing efforts to strengthen pharmaceutical manufacturing are key drivers. The rising awareness of epilepsy treatment options and the need for affordable anticonvulsants are fueling Alcohol Withdrawal demand. Market growth is also facilitated by international aid and collaborations aimed at improving drug quality and supply chain resilience. As the healthcare infrastructure continues to develop, Sri Lanka presents a promising landscape for phenobarbital market expansion.

• Severe adverse events (hypotension below a systolic blood pressure of 90 mmHg, respiratory depression or distress requiring intubation, cardiac arrest or pre-arrest events (e.g., “Code Blue” events), and the etiology of these events) will be reviewed by the DSMB, who may recommend to the Steering Committee to stop the trial.
• Local pharmaceutical companies are investing in production capabilities, ensuring a consistent supply of phenobarbital.
• Hepatology outpatient follow-up appointments offer an ongoing chance to check in with patients about recovery and provide continued nonjudgmental support—with particular attention to stability, AUD medication efficacy and side effects, and engagement with psychosocial treatments and additional recovery support at each outpatient visit.
• Phenobarbital interacts with the mortality-reducing opioid agonist therapies buprenorphine and methadone, risking delayed opioid withdrawal and relapse when administered concurrently.
• Supply-side capabilities, including production scalability and distribution networks, are improving, enabling companies to meet growing demand efficiently.

The future growth prospects for the Phenobarbital API market are positive, driven by increasing investment in healthcare infrastructure and rising demand for anti-seizure medications. Some outpatient programs are intensive, providing monitoring during the day while administering medication as needed and giving medication to take overnight when the patient returns home or to a shelter. Other outpatient programs may consist of brief daily visits with the assessment of withdrawal, administration of medication for withdrawal, and supplies of take-home medications for use later in the day and overnight. For individuals who want to stop alcohol use and are not already hospitalized, a decision needs to be made regarding the treatment setting (see Figure 2). Many individuals with AUD can have their withdrawal managed as an outpatient.52 The choice between inpatient and outpatient treatment should be based on comorbid medical or psychiatric conditions and the severity of alcohol withdrawal, as well as the resources available.

A REDCap database (with appropriate range-checks for data entry) will be used to maintain data integrity. Patients who wish to withdraw from the pilot trial (e.g., following enrollment under deferred consent) will be asked whether we can prospectively follow them to include their outcomes. Unless they agree, their data will be excluded from the planned analyses and additional patients will be randomized in order to meet our target recruitment. The primary objective of the PHENOMANAL trial will be to demonstrate our ability to recruit 39 patients over the trial period. The management of acute alcohol withdrawal poses a significant challenge in clinical practice, often necessitating pharmacological intervention to mitigate symptoms and prevent complications.

• Although small and retrospective, these 2 studies provide more evidence to support the use of phenobarbital in severe AWS, especially as monotherapy.
• However, this trial was limited to patients presenting to the emergency department (ED) with sAAWS, investigated symptom-triggered lorazepam treatment (not the current standard of care), and only reported on 50% of randomized participants for various reasons including an inability to obtain first-party consent 16.
• Market growth is also facilitated by international aid and collaborations aimed at improving drug quality and supply chain resilience.
• Avoiding excessive use of PB among patients with suspected OUD ought to be a QI metric in applicable hospitals.
• Additionally, monthly fees, as well as call back fees, will enable after hours preparation of study drugs.

Stages of alcohol-associated liver disease

Last, because not all patients in the “new-adopter hospitals” received phenobarbital, the results from the DiD analysis may not be attributable to individual receipt of phenobarbital; however, the exploratory analysis evaluating individual receipt of phenobarbital also suggests an association between phenobarbital use and lower rates of IMV initiation. In designing and implementing the trial, we addressed challenges including the need to identify patients outside of regular research hours and safety issues related to patients who express a desire to leave against medical advice after receiving study intervention. To maximize our ability to identify and recruit eligible patients during the trial period, physicians will rotate weeks “on call” to identify eligible trial participants after hours and on weekends. To facilitate after hours enrollment, we will have a pharmacist on call to prepare and dispense study medication for the trial.

Given that many patients with ALD also have AUD, the hepatologist must be comfortable and competent in managing both disorders. When it comes to benzodiazepine withdrawal, a carefully planned protocol is crucial to ensure a smooth and safe transition. The goal of using phenobarbital is to help manage symptoms of withdrawal, such as anxiety, insomnia, and seizures, while the body adjusts to the absence of benzodiazepines. Although small and retrospective, these 2 studies provide more evidence to support the use of phenobarbital in severe AWS, especially as monotherapy. Previous studies have also shown similar benefits in decreasing LOS and the need for additional agents.1,9-11 These 2 studies reinforce the safety and efficacy of the use of phenobarbital as monotherapy to decrease the risk of oversedation and respiratory depression. We will record adverse events including intubation, aspiration, seizure, use of non-invasive (NIV) or invasive ventilation.

Liver biopsy was previously the gold standard for the diagnosis and assessment of steatosis and fibrosis; however, this modality is being replaced with noninvasive testing, including blood-based tests and elastography. In current practice, liver biopsy is reserved for situations where noninvasive testing is inconclusive or when the underlying etiology of liver disease is unclear. Phenobarbital, a barbiturate medication, has been used to treat benzodiazepine withdrawal in some cases. It works by slowing down the activity of the brain and nervous system, which can help alleviate symptoms of withdrawal. Phenobarbital can be used to manage symptoms such as anxiety, insomnia, and seizures, which are common during benzodiazepine withdrawal.
