Its consistent dosing simplifies patient compliance and monitoring of side effects over long-term therapy. Generic and branded versions of 1 mg tablets are readily available, ensuring broad patient access. In addition, bulk procurement by hospitals and government programs further strengthens the segment’s dominance.

The Others segment, including strengths such as 0.5 mg or 2 mg tablets, is expected to witness the fastest growth during the forecast period due to increasing adoption in personalized therapy approaches and dosage adjustments based on patient-specific requirements. Oncologists may prescribe lower or higher doses for patients with comorbidities or varying tolerance levels. Growth is also driven by emerging clinical studies exploring combination therapies that require alternative strengths. Hospitals and specialty oncology centers are gradually incorporating these variations to optimize therapeutic outcomes. The expansion of clinical trials in Asia-Pacific and Latin America further supports demand for non-standard strengths.

• By Drug Class

On the basis of drug class, the market is segmented into aromatase inhibitors and antineoplastics. The aromatase inhibitor segment dominated the market with a revenue share of 73.5% in 2025, as anastrozole is widely recognized as a standard aromatase inhibitor for postmenopausal breast cancer patients. This class is preferred over other therapies due to its high efficacy in reducing estrogen production and controlling tumor progression. The segment’s dominance is supported by clinical guidelines from organizations such as NCCN and ESMO. Its extensive adoption across hospitals, clinics, and specialty oncology centers contributes to steady revenue growth. Patients benefit from well-documented safety profiles and long-term tolerability, further reinforcing preference for aromatase inhibitors. Pharmaceutical companies continue to invest in R&D to optimize formulations within this class.

The antineoplastic segment is anticipated to witness the fastest growth rate of 6.8% CAGR from 2026 to 2033, driven by increasing exploration of combination therapies where anastrozole is used alongside other chemotherapeutic agents. Ongoing clinical trials targeting multiple cancer pathways create opportunities for integration with antineoplastic regimens. The growth is supported by hospitals and oncology specialty clinics adopting combination therapy protocols. Pharmaceutical firms are focusing on co-branded therapies and supportive care packages to increase adoption. Expansion in emerging markets with improving oncology infrastructure also fuels segment growth.

• By End-Users

On the basis of end-users, the market is segmented into clinics, hospitals, and others. The hospital segment dominated the market with a revenue share of 58.9% in 2025, as hospitals serve as the primary point of care for breast cancer diagnosis, treatment, and follow-up. Hospitals provide structured treatment plans, monitor patient adherence, and manage side effects, making them the preferred setting for anastrozole therapy. Strong purchasing power and formulary inclusion allow hospitals to procure both branded and generic tablets in bulk. Oncology departments ensure continuous supply and professional administration. The dominance is further supported by the availability of patient education programs and clinical monitoring facilities. Hospitals in North America and Europe account for the majority of consumption due to advanced oncology care infrastructure.

The clinics segment is expected to witness the fastest growth rate of 7.3% CAGR from 2026 to 2033, driven by the rising number of outpatient oncology clinics and specialized cancer care centers offering personalized therapy programs. Clinics provide convenient access for follow-up consultations and long-term therapy management. Adoption is higher in urban regions where patients prefer localized treatment options. Growth is also fueled by telemedicine integration, allowing clinicians to monitor adherence and side effects remotely. The rise of private oncology clinics in Asia-Pacific and Latin America contributes to increasing market share for clinic-based administration.

• By Distribution Channel

On the basis of distribution channel, the market is segmented into hospital pharmacy, retail pharmacy, and online pharmacy. The hospital pharmacy segment dominated the market in 2025 with a revenue share of 54.6%, as hospitals are the primary distribution point for oncology medications including anastrozole. Hospital pharmacies ensure regulated dispensing, patient counseling, and adherence monitoring. The integration with electronic medical records facilitates prescription accuracy and inventory management. Strong purchasing contracts with pharmaceutical companies ensure continuous supply. Patients receiving therapy at hospitals prefer in-house pharmacy access for convenience and reliability. In addition, hospitals often provide patient assistance programs and subsidized pricing for long-term therapy.

The online pharmacy segment is expected to witness the fastest growth rate of 8.2% CAGR from 2026 to 2033, driven by increasing e-commerce adoption, patient preference for home delivery, and the growing trend of telemedicine consultations. Online pharmacies offer subscription models, price comparisons, and doorstep delivery, enhancing convenience for long-term therapy patients. Growth is particularly strong in developed regions with high digital literacy. Mobile apps and automated reminders for refill and adherence further support segment expansion. Emerging markets are gradually adopting online platforms as access to retail and hospital pharmacies remains limited in rural areas.

What are the Recent Developments in Global Anastrozole Tablets Market?

• In April 2024, a sub‑study of the IBIS-II prevention trial reported that anastrozole treatment did not cause significant long-term changes in body composition (fat or fat-free mass) in high-risk postmenopausal women, helping address concerns about weight gain with preventive therapy
• In March 2024, researchers at Manchester University NHS Foundation Trust published research (in Lancet Oncology) on a highly sensitive blood test that measures oestradiol levels, which could help predict which post menopausal women at high risk will or will not benefit from preventive anastrozole therapy. The study found that up to 25% of high-risk women have very low baseline oestradiol, and these women may derive little benefit from anastrozole
• In November 2023, the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) granted a licence variation for anastrozole to be used for primary prevention of breast cancer in post menopausal women at moderate or high risk. This new indication aligns with previous trial evidence (IBIS-II) showing that anastrozole can reduce breast cancer incidence in this high-risk group
• In November 2023, NHS England announced that around 289,000 post-menopausal women in England could now be eligible to take anastrozole as a preventive therapy, estimating that up to 2,000 breast cancer cases might be prevented if ~25 % of eligible women opt in. This rollout is based on a modelling of uptake and such asly benefits, tied to the newly granted MHRA licence
• In May 2023, data from the Phase III AERAS trial showed that extending adjuvant anastrozole therapy to 10 years in postmenopausal women with hormone-receptor positive breast cancer improved disease-free survival (DFS) significantly compared to stopping at 5 years
