In the simplest terms, an API is the component of a medication that produces the intended therapeutic effect. While APIs are crucial, they are only part of the complex puzzle that constitutes a pharmaceutical product. A complete medication can include various excipients—substances that serve as vehicles for the active ingredients, ensuring proper delivery, stability, and performance of the drug.
PQQ is a redox cofactor that was first identified as a required nutrient in bacteria. While its role in human health is still being explored, research suggests that PQQ is involved in numerous biological processes. It is known to promote the growth of new mitochondria—a process known as mitochondrial biogenesis. This is particularly important as mitochondrial function declines with age, leading to reduced energy levels and increased oxidative stress.
APIs are crucial in the development of safe and effective medications. They undergo rigorous testing for efficacy, safety, and stability before being approved for use. The process of developing an API involves several stages, including discovery, preclinical testing, clinical trials, and regulatory approval. Once an API passes these stages, it can be formulated into a drug product, which may include excipients or inactive ingredients that aid in the delivery of the active substance.
