Polymers that are neutral (e.g., non-ionizable across the GI pH range) and hydrophilic (high water solubility) such as polyvinyl pyrrolidone (PVP) and hydroxypropyl methylcellulose (HPMC) are useful for maximizing dissolution rate across the pH range of the GI tract, particularly for highly lipophilic, weakly basic compounds in the low pH environment of the stomach.
