Types segmentation classifies drugs by molecular architecture and delivery platform, revealing how innovation influences market composition. Small‑molecule oral agents, such as metformin analogues and SGLT2 inhibitors, remain the largest type, capturing roughly 55 % of the market due to established manufacturing, generic competition, and broad prescribing. Biologic therapies—including monoclonal antibodies targeting PCSK9 or GLP‑1 receptors—account for about 25 %, reflecting higher price points and specialty‑care adoption. Peptide‑based drugs, delivered via subcutaneous injection, contribute near 12 %, driven by rapid growth in GLP‑1 and amylin analogues. Gene‑therapy and RNA‑based modalities, still early‑stage, represent the remaining 8 %, indicating future upside as regulatory pathways mature. Within each type, sub‑categories (e.g., selective versus non‑selective inhibitors) further differentiate pricing power and pipeline intensity, reinforcing the overall market taxonomy for chronic metabolic disease drugs.
