What are small molecule drugs?

Small molecule drugs are the foundation of classic drive development. Small molecules are synthesized by chemical reactions between different organic/inorganic compounds. High-throughput automated methods help researchers screen for small molecules which can be a starting point (or lead compound) for a new drug. These medicines can be processed into tablets or capsules. Due to their small size, once ingested, the dissolved active substance is absorbed into the bloodstream reaching virtually any desired location.
