Step 2: Bottom-Up Approach

The bottom-up approach was used as the primary method for estimating the United States Pharmaceutical Market.

The calculation began with pharmaceutical sales and prescription volumes across major products, therapeutic areas, drug types, and distribution channels. The market value was derived using pharmaceutical sales values, units sold, prescriptions dispensed, and applicable pricing information.

Core Formula:

United States Pharmaceutical Market = Pharmaceutical Units Sold X Average Pharmaceutical Price

Where reliable sales-value information was available, reported pharmaceutical sales were incorporated directly into the calculation.

For prescription medicines, the analysis also considered:

Prescription Pharmaceutical Market = Number of Prescriptions X Average Revenue per Prescription

The calculation was performed separately across major therapeutic categories because treatment volumes, product prices, generic penetration, specialty-drug adoption, and reimbursement conditions vary significantly between therapeutic areas.

Step 3: Pharmaceutical Sales Volume and Average Selling Price

Pharmaceutical sales volumes were estimated using pharmaceutical-company disclosures, prescription data, sales audits, regulatory information, distributor data, industry databases, government statistics, and primary research.

Average Pharmaceutical Price = Pharmaceutical Sales Value ÷ Pharmaceutical Units Sold

The assessment considered differences in:

• Brand versus generic medicines
• Prescription versus OTC medicines
• Specialty versus traditional medicines
• Small-molecule versus biologic products
• Retail versus non-retail medicines
• Hospital versus outpatient medicines
• Dosage form
• Strength
• Pack size
• Treatment duration
• Wholesale acquisition cost
