Introduction

An active pharmaceutical ingredient (API) is the primary biologically active component of a medical drug formulation that is responsible for the therapeutic effect. In ancient times, when the molecular structure and identity of the APIs were unknown, remedies composed of plants, animal by-products, and even minerals were utilized to heal, treat, and prevent the spread of disease. With the advancement of civilization, the field of medicine made fast progress, and APIs were synthesized rather being extracted from natural sources. Aspirin is generally considered the first synthetic drug, although others describe chloral hydrate as the first synthetic drug in medical history [1].

The pharmacokinetics and pharmacodynamics of an API, which are influenced by their structure, mostly govern the therapeutic efficiency, and owing to this, APIs have various chemical functional groups. These functional groups are usually capable of forming strong inter-/intramolecular interactions via...
