Introduction For Methadone Formulations

Opioid use disorder (OUD) has posed a critical public health challenge in Thailand, notably in the northern regions where heroin and opium abuse remain prevalent. In response, methadone maintenance therapy (MMT) has been officially integrated into Thailand’s national substance abuse programs since 2018, with varied but promising results.

This article examines Methadone formulations available for providers. It reviews up-to-date statistics from Thailand’s OUD programs. It also showcases the extensive methadone product range that Vonage Pharma delivers to healthcare institutions.

Methadone Formulations: Essential Options for Providers

Methadone’s long-acting profile, proven track record, and adaptability across clinical settings have made it a first-line medication for both opioid detoxification and long-term maintenance therapy. Vonage Pharma supports Thai healthcare providers with a broad portfolio of methadone options, tailored for clinical flexibility:

• Methadone HCl – Bulk active pharmaceutical ingredient (API) for customized compounding.
• Methadone Hydrochloride 5 mg – Low-dose tablets ideal for initial titration or microdosing.
• Methadone 20 mg – Tablets designed for maintenance dosing in stabilized patients.
• Methadone Hydrochloride 40 mg – High-strength formulation minimizing pill burden for patients needing larger doses.
• Methadone Oral Solution 25 mg/5 ml – Rapid absorption, flexible dosing, and ease of supervision for outpatient programs.

Each formulation is manufactured to globally recognized cGMP and ISO standards, ensuring pharmaceutical-grade safety, consistency, and regulatory compliance for Thai hospitals and addiction centers.

Statistical Overview: Methadone in Thailand’s Opioid Dependence Programs

Patient Access and Retention Rates

Thailand’s integration of methadone in its OUD treatment pathways has yielded notable results:

• Access to Methadone Therapy: In Northern Thailand, 78.5% of opioid use disorder (OUD) patients accessed MMT, driven by expanded harm reduction policies and strengthened governance in hospitals (Thaijo).
• One-Year Retention:4% of MMT patients in surveyed hospitals remained in therapy for at least one year—a key quality marker linked to improved health outcomes and reduced relapse (Thaijo).
• Six-Month Retention: At Prachuap Khiri Khan Hospital, 37.3% of patients remained in treatment for over six months, with an average stay of 6.3 months (Thaijo).

Clinical Benefits and Quality of Life

Studies highlight that MMT in Thailand leads to:

• Reduced Heroin Use: Surveys indicate an 86% decrease in heroin use among patients in MMT, compared to non-maintenance-based rehabilitation (UNSW).
• Improved Social and Health Outcomes: 84% of MMT recipients report better social and family life, while 58% experience gains in physical health and employment (UNSW).
• Lower Relapse and Illegal Activity: Consistently, MMT was linked to decreased involvement in illegal activities and a greater chance of long-term abstinence (UNSW).

Formulation-Specific Insights

• Oral Tablets (5 mg, 20 mg, 40 mg): Reliable for outpatient maintenance and individualized titration. Lower strengths (5 mg) facilitate gradual induction and microdosing protocols while higher strengths reduce pill counts for established patients.
• Oral Solution (25 mg/5 ml): Especially valued in hospital settings and harm reduction clinics, offering flexibility for patients who have swallowing difficulties or require supervised dosing.
• Bulk Methadone HCl: Enables hospital pharmacies to prepare tailored formulations for specific patient needs, optimizing dosing accuracy and minimizing risks of dosing errors.

Thailand’s Methadone Maintenance Therapy: Policy and Practice

Since its national rollout, MMT has become a mainstay in opioid dependence care in Thailand:

• As of 2023, only 37.8% of hospitals in Northern Thailand actively provided MMT, with 78.5% of OUD patients in active service areas accessing methadone formulations (Thaijo).
• Hospitals with robust MMT programs reported over 71% retention at one year, above historic benchmarks. However, workforce shortages, staff training gaps, and limited resources remain ongoing challenges for regional expansion (Thaijo).
• Most common barriers: lack of MMT staff, logistics issues for medicine delivery, limited patient outreach, and persistent social stigma.
