KEY TAKEAWAYS:
• Pharma brands grow through more prescribers, not major increases in prescription frequency
• Brand consistency outperforms continuous modernization across consumer and pharma markets
• Evidence reveals reproducible growth patterns that challenge traditional loyalty-focused assumptions
• Occasion-based strategies require integrated physical and mental availability at decision moments
• Sustainable transformation demands five-to-six-year, cross-functional capability building beyond marketing
Aniruddha Kusurkar spent over 15 years in commercial roles before confronting an uncomfortable truth about his marketing education. "I could never really reconcile with the view of hardcore loyal consumers," he explained. "Even after working on some of these brands myself, I couldn't force that kind of loyalty from my own mother." This realization catalyzed a transformation in how FrieslandCampina approaches brand building—a shift grounded in research from the Ehrenberg-Bass Institute that challenges pharma industry assumptions about prescriber relationships.
The evidence contradicts conventional wisdom about deepening existing prescriber engagement. "Big pharma brands have got more active prescribers, in fact many more, and they prescribe those brands slightly more often," Philip Stern noted. "The key implication for you, from our work, is that penetration or breadth is the route to what we would call sustainable growth." For pharma executives accustomed to intensive key opinion leader cultivation and high-decile account management, this represents a fundamental strategic reorientation.
Evidence Validates Penetration Over Frequency
The Ehrenberg-Bass Institute approaches marketing as a scientific discipline rather than creative speculation. "What we try and do is find real scientific law-like relationships, which you don't often see within the social sciences and within marketing," Stern stated. As the world's largest marketing research center, the Institute identifies patterns that hold across contexts—from shampoo purchases to aviation fuel contracts to pharma prescribing behavior.
The fundamental pattern appears consistently: market leaders command dramatically larger customer bases while showing only marginally higher loyalty metrics. Stern highlighted consumer data showing the top shampoo brand in the United States achieving penetration levels ten times higher than smaller competitors, while purchase frequency varied by only a factor of two. "Big brands have more customers, a lot more customers than small brands and those big brands attract slightly higher loyalty," he explained.
Does professional medical decision-making exempt pharma from these patterns? The evidence suggests otherwise. Analysis of the English Prescribing Dataset for antidepressants revealed fluoxetine prescribed by 38% of general practitioners at an average frequency of 1.4 times monthly, while fluvoxamine reached only 1% of practices with virtually identical prescribing frequency among users. The breadth variation of 38-fold dwarfed the negligible depth difference.
United States data for psoriatic arthritis among dermatologists showed 23-fold variation in prescriber penetration versus twofold variation in prescribing frequency. Identical patterns emerged across rheumatologists treating axial spondyloarthritis, cardiologists managing congestive heart failure, and primary care physicians across therapeutic areas. Clinical importance and professional training do not insulate pharma brands from the fundamental relationship between market size and prescriber base.
Practitioner Journey From Theory to Implementation
FrieslandCampina's transformation began when leadership recognized that evidence contradicted established practices. As the fifth-largest global dairy company, FrieslandCampina manages brands including Yazoo and Chocomel in the United Kingdom. Kusurkar's chemical engineering background and experience selling toilet cleaners, soaps, and dairy products positioned him to appreciate analytical rigor over marketing convention. His conversion to evidence-based principles 12 years ago has shaped his commercial strategy ever since.
The company's portfolio offers a contrast between consistency and modernization. Chocomel, acquired in 2014, maintained remarkable visual and positioning stability over decades. Kusurkar attributed its strength to minimal packaging changes, consistent recognition cues, and resistance to redesign impulses. "A brand is simply recognition for a certain proposition people want to buy," he stated. "Make it easy for them, don't confuse them and don't try to fill your own space with activities that in the end hurt the brand." This "boring" consistency correlated with strong performance.
“By contrast, we also have examples of brands where we were less consistent with the visual identity as successive marketers attempted changes that they believed were relevant to modernize and differentiate the brand. Frisian Flag in Indonesia is a good example where we moved away significantly from the original visual identity and therefore risked creating consumer confusion. Modernization is not a consumer requirement, it is a marketeer requirement," Kusurkar observed. The lesson applies equally to pharma brands where visual identity refreshes and repositioning may satisfy internal stakeholders while undermining recognition.
FrieslandCampina embedded five principles into operations: push for penetration rather than volume alone, focus on occasions rather than romanticized need states, accept that traditional loyalty doesn't exist, prioritize distinctiveness over differentiation, and maintain consistency. "More people need to buy us a greater number of times every year," Kusurkar said. Occasion-based thinking required portfolio architecture aligned with purchasing contexts. The company developed Rally, an internal methodology for testing brand assets against recognition criteria rather than aesthetic preference; recognition on shelf became the primary design metric.
Implementation required capability building across finance, supply chain, and sales—not just marketing. "I actually find some of my finance and supply chain colleagues much more enthusiastic, sadly, compared to some of my marketeers," Kusurkar noted. The transformation took five to six years, using crises such as COVID-19 and inflation as integration opportunities. "Trust, credibility and capability comes on foot and it leaves on horseback," he reflected. "So it's hard to build this. It's very easy to lose it."
Rethinking Pharma Resource Allocation
The evidence challenges pharma's commercial model assumptions. Traditional strategies emphasize deepening relationships with existing prescribers through advisory boards, speaker programs, and intensive management of high-decile physicians. If penetration drives growth more powerfully than frequency, resource allocation may be misaligned. The question becomes whether marginal investments in expanding prescriber bases would generate superior returns compared to incremental engagement with established prescribers.
Kusurkar's framework posits that brand growth requires only two elements: increased distribution and increased awareness. "In the end, the only way a brand works and becomes big is if it increases distribution and if it increases awareness," he stated. "I think that's it. Yeah, it is not more complex than this." Physical availability and mental availability must converge at decision moments.
For pharma, physical availability encompasses formulary access, inventory, prior authorization pathways, and sample availability. Mental availability involves prescriber awareness, category entry point associations, and recall at clinical decision moments. Occasion-based thinking translates directly to specialist initiation, primary care maintenance, hospital discharge, formulary reviews, and urgent care. Each occasion requires different availability strategies, and gaps at any point can limit penetration.
The Shell aviation fuel example shows that professional B2B decisions follow identical dynamics—73% airline penetration with moderate contract frequency outperforms deep relationships with narrow customer bases. "It even works in something like aviation fuel," Stern noted. The pharma context does not exempt brands from these patterns.
Building Capability for Sustainable Transformation
FrieslandCampina's experience reveals that evidence-based transformation cannot succeed as a marketing initiative alone. "Start from the top," Kusurkar emphasized. "This is not a program for marketeers. This is a program for everyone in the company." Leadership commitment, cross-functional engagement, and concrete tools are critical to embedding these principles.
Stern concluded with an architectural metaphor: marketers need to understand scientific principles before applying creativity, just as architects require physics before designing ambitious structures. "Just like architects, marketers need to understand the science and then put the creativity on top of that science," he stated. Effective marketing requires a foundation in evidence about how brands actually grow; creativity then determines how best to build mental and physical availability, maintain distinctiveness with consistency, and organize resources for penetration expansion.
For pharma executives, the key question is not whether these patterns apply—the prescribing data confirms they do—but how quickly they can redirect resources toward penetration-building strategies that evidence demonstrates drive sustainable growth.
