Drugs and patents in ATC class G04B

Last updated: July 30, 2025

Introduction

The global urological therapeutics market, classified under ATC Class G04B, encompasses a broad spectrum of drugs and devices targeting urological disorders such as benign prostatic hyperplasia (BPH), erectile dysfunction, urinary incontinence, and other related conditions. The market landscape is shaped by evolving technological advancements, shifting demographic trends, and a robust pipeline of innovative pharmaceuticals. This analysis explores the current market dynamics and the patent landscape for G04B, providing strategic insights for industry stakeholders.

Market Overview and Key Drivers

Growing Prevalence of Urological Disorders

The increasing incidence of urological conditions, driven by aging populations and lifestyle factors, remains a core market driver. For example, BPH affects approximately 50% of men aged 51-60 and up to 90% of men over 80 [1]. This demographic trend fuels demand for pharmacological treatments, surgical devices, and minimally invasive procedures.

Advancements in Pharmacotherapies

Recent breakthroughs include novel classes of drugs such as selective alpha-blockers and 5-alpha-reductase inhibitors, enhancing efficacy and reducing adverse effects. The development of combination therapies has further expanded treatment options, consolidating market growth.

Technological Innovation and Minimally Invasive Devices

Innovation extends beyond pharmaceuticals into the device domain, with an increasing shift towards minimally invasive procedures like laser surgeries, stenting, and novel urinary incontinence devices. Regulatory approvals for such devices have accelerated, driven by the demand for outpatient solutions.

Regulatory and Patent Challenges

Strong patent protections provide market exclusivity, incentivizing innovation but also posing barriers for generic entry, thereby maintaining high product prices. Patent expiries for key drugs have historically precipitated market shifts towards generics.
