The pharmaceutical landscape for topical retinoids has undergone significant evolution, with Adapalene emerging as a cornerstone in acne vulgaris treatment. This report provides a comprehensive analysis of the market dynamics and price projections for Adapalene under National Drug Code (NDC) 68308-0706, manufactured by Mayne Pharma Inc. The deletion of this specific formulation in September 2024 introduces unique considerations for market behavior, competitive positioning, and future pricing trends.
Historical Context and Product Overview
Structural Breakdown of NDC 68308-0706
The NDC system identifies Adapalene 68308-0706 as follows:
- Labeler Code (68308): Mayne Pharma Inc., a subsidiary of Mayne Pharma Group, specializing in dermatology and women’s health products[1].
- Product Code (0706): Specific to a 0.1% Adapalene formulation, which was discontinued effective September 30, 2024[1].
Adapalene, a third-generation retinoid, inhibits comedogenesis and modulates keratinocyte differentiation, offering anti-inflammatory benefits with fewer side effects compared to earlier retinoids like tretinoin[7][10]. Its efficacy in reducing inflammatory and non-inflammatory acne lesions has been validated in multicenter trials, establishing it as a first-line therapy[7].
Market Position Prior to Discontinuation
Prior to its deletion, NDC 68308-0706 competed in a crowded generic market. Key differentiators included:
- Formulation stability: Adapalene’s photostability allowed for daytime use, unlike tretinoin[10].
- Tolerability: Meta-analyses demonstrated significantly lower rates of erythema and scaling compared to tretinoin 0.025% gel[7].
- OTC Availability: The 2016 FDA approval of Differin 0.1% gel for over-the-counter (OTC) use expanded accessibility but intensified price competition[14].
Mayne Pharma’s decision to discontinue NDC 68308-0706 aligns with industry trends favoring combination therapies (e.g., Adapalene/benzoyl peroxide under NDC 68308-0662) and higher-concentration formulations (0.3% Adapalene)[1][12].
Regulatory and Competitive Landscape
FDA Regulations and Market Entry Barriers
The OTC switch of Adapalene in 2016 catalyzed market expansion but introduced challenges:
- Safety Monitoring: Post-marketing surveillance revealed off-label use during pregnancy despite teratogenicity warnings, necessitating enhanced labeling[8].
- Generic Competition: Teva’s 2017 launch of generic Epiduo (Adapalene/benzoyl peroxide) captured 22% of the combination therapy market within 18 months[6].
Global Market Dynamics
- North America: Accounts for 48% of global Adapalene sales, driven by high acne prevalence (85% of adolescents affected) and insurance coverage for prescription-strength formulations[6][14].
- Europe: Projected CAGR of 6.8% (2024–2030), fueled by novel delivery systems like La Roche-Posay’s Effaclar Adapalene 0.1% gel[6].
- Asia-Pacific: Emerging markets leverage cost-effective API production, with Indian manufacturers supplying 65% of global Adapalene raw material[12].
Pricing Analysis and Historical Trends

Data extrapolated from IQVIA MIDAS shows consistent 4–5% annual price erosion, mirroring broader generic market trends[2][11].
Impact of Discontinuation on Pricing
The September 2024 deletion creates short-term supply constraints:
- Inventory Depletion: Distributors reported a 73% stock reduction by Q3 2024, triggering a 12% price spike in remaining inventory[1].
- Therapeutic Substitution: Patients shifted to alternative NDCs (e.g., 68308-0666) or combination products, mitigating long-term price volatility[1][6].
Future Price Projections (2025–2030)
Methodology
Projections incorporate:
- Market Demand: 2.3% annual growth in acne treatment prescriptions[12].
- Competitive Intensity: 4–6 new ANDA filings for Adapalene expected by 2026[14].
- Regulatory Pressures: Inflation Reduction Act (2022) provisions capping annual price increases at CPI-U + 0% for Medicare Part D drugs[11].

Baseline Assumptions:
- 2025: Residual inventory exhausts, prices stabilize at $9.10 with competing generics[2].
- 2026–2028: New entrants drive 5.2% annual erosion[12].
- 2029–2030: Market maturation reduces erosion to 3.8% annually[11].
Strategic Challenges and Opportunities
Challenges for Mayne Pharma
- Portfolio Optimization: Transitioning prescribers to higher-margin products like Adapalene/benzoyl peroxide (NDC 68308-0662) requires rebate incentives averaging 18%[1].
- API Cost Volatility: Adapalene API prices rose 9% in 2024 due to quinoline derivatives shortages[12].
Market Opportunities
- Emerging Formulations: Microencapsulated Adapalene (0.3%) trials show 31% superior efficacy vs. legacy gels[12].
- Telemedicine Integration: Direct-to-consumer platforms increased Adapalene prescriptions by 14% in 2024[14].
Conclusion
The deletion of NDC 68308-0706 reflects strategic realignment in Mayne Pharma’s dermatology portfolio rather than therapeutic obsolescence. While short-term pricing fluctuations are inevitable, the broader Adapalene market remains robust, projected to reach $1.2 billion by 2030. Stakeholders should monitor:
- Regulatory Shifts: Potential OTC expansion of combination products.
- Supply Chain Innovations: Continuous manufacturing platforms reducing API costs by 15–20%[12].
- Global Expansion: Southeast Asia’s acne treatment market growing at 8.9% CAGR[6].
Adapalene’s clinical utility and evolving formulations ensure its enduring relevance, with pricing stabilized through portfolio diversification and operational efficiency.
“The future of topical retinoids lies in personalized formulations—Adapalene’s molecular stability makes it ideal for next-gen delivery systems.”
