PQQ is a naturally occurring compound found in various foods, including fermented soybeans, green tea, spinach, and certain fruits. In the human body, it plays a vital role in cellular metabolism and mitochondrial function. Mitochondria, often referred to as the powerhouses of cells, are critical for energy production. PQQ has been shown to stimulate the growth of new mitochondria, a process known as mitochondrial biogenesis, which can lead to improved energy metabolism and overall cellular health.
Just like with APIs, stability testing for FPPs typically involves long-term, accelerated, and intermediate studies. The results help determine the product's expiration date and the specific conditions under which it should be stored. It also informs the labeling of the product, ensuring that patients and healthcare providers use the medication safely and effectively.
An Active Pharmaceutical Ingredient (API) is the biologically active component of a drug product. It is the substance or mixture of substances intended to diagnose, cure, mitigate, treat, or prevent diseases in humans or animals. APIs can be derived from various sources, including synthetic compounds, natural extracts, and biotechnology processes. The quality of an API is paramount, as it directly impacts the safety and efficacy of the final drug product.
