AI Agent ROI: Measuring the Business Impact of Autonomous Sales Assistants

Opening

The pharmaceutical industry is experiencing a significant shift, with pharmaceutical sales declining 10% to $12.7 billion in the first quarter of 2023 according to Merck. This decline highlights the need for innovative solutions to boost growth and increase revenue. One potential solution is the use of AI agents, which could boost growth by 5.0 to 13.0 percentage points in pharma according to McKinsey. In this article, we will explore the current state of the pharmaceutical industry, the challenges it faces, and how AI agents can help address these challenges and drive growth.

The Current State

The pharmaceutical industry is a complex and competitive market, with companies like Merck, Amgen, and Pfizer vying for market share. Despite the decline in pharmaceutical sales, some companies are experiencing growth, with Merck's pharmaceutical sales growing 14% in the first quarter of 2023, excluding LAGEVRIO according to Merck. Additionally, Pfizer's Keytruda recorded sales of $23.3 billion in the first nine months of 2025, up 8% year over year according to Zacks. These companies are leveraging innovative technologies, such as AI, to drive growth and stay ahead of the competition. For example, Amgen's top-selling drug Enbrel generated $4.8 billion in sales in 2020 according to Markets Gone Wild. The use of AI agents is becoming increasingly important in the pharmaceutical industry, with the potential to increase EBITDA by 3.4 to 5.4 percentage points according to McKinsey.

The pharmaceutical industry is also experiencing a shift towards personalized medicine, with companies using AI to develop targeted therapies. For example, AstraZeneca has a market cap of $287.48 billion and annual revenue of $58.13 billion according to Britannica Money, and is using AI to develop personalized cancer treatments. The use of AI in the pharmaceutical industry is not limited to personalized medicine, with companies also using AI to improve sales and marketing efforts. For example, AI agents can enable context-aware conversations, detect emotional cues, and guide reps in real-time according to Hexaware Technologies.

The Challenge

Despite the potential of AI agents, the pharmaceutical industry faces significant challenges in implementing these solutions. One of the main challenges is competitive pressure, which can lead to declining sales and revenue. For example, Adcetris sales declined 20% year over year due to competitive pressure according to Zacks. Additionally, the pharmaceutical industry is heavily regulated, with strict guidelines and regulations governing the use of AI and other technologies. This can make it difficult for companies to implement AI solutions, and can limit the potential benefits of these solutions.

The pharmaceutical industry is also facing challenges in terms of data quality and availability. For example, pharmaceutical companies often have limited access to high-quality data, which can make it difficult to develop and implement effective AI solutions. Additionally, the pharmaceutical industry is facing challenges in terms of talent and skills, with a shortage of professionals with expertise in AI and data science. This can make it difficult for companies to develop and implement effective AI solutions, and can limit the potential benefits of these solutions.

What's Working

Despite the challenges, some pharmaceutical companies are experiencing success with AI agents. For example, Merck is using AI to improve sales and marketing efforts, with the potential to boost growth by 5.0 to 13.0 percentage points according to McKinsey. Additionally, Pfizer is using AI to develop personalized cancer treatments, with the potential to increase EBITDA by 3.4 to 5.4 percentage points according to McKinsey.

Some best practices for implementing AI agents in the pharmaceutical industry include:

* Developing a clear strategy for AI adoption, with specific goals and objectives

* Investing in high-quality data and analytics, to support the development of effective AI solutions

* Building a team with expertise in AI and data science, to support the development and implementation of AI solutions

* Collaborating with external partners, to leverage expertise and resources in AI and data science
