Within the Types classification, oral anorexiants are organized by pharmacological mechanism into four sub‑categories: Serotonin receptor agonists, Norepinephrine reuptake inhibitors, Combination therapies, and Natural extracts. Serotonin receptor agonists (e.g., lorcaserin) comprise roughly 40 % of the product mix, leveraging 5‑HT2C activation to promote satiety; their market share is moderated by recent regulatory scrutiny. Norepinephrine reuptake inhibitors (such as phentermine) hold about 30 % of volume, exploiting central sympathetic pathways to reduce appetite, though safety concerns limit long‑term use. Combination therapies—often pairing a serotonin agonist with a norepinephrine inhibitor—account for 20 % of sales, offering synergistic efficacy and broader prescriber acceptance. Finally, Natural extracts (including green‑tea catechins and Garcinia cambogia) represent the remaining 10 %, driven by consumer preference for botanical options despite limited clinical validation. This taxonomy clarifies how each type contributes to overall market dynamics and informs strategic positioning within the Oral Anorexiant Drug market.
