PQQ is a small molecule that possesses a quinone structure, which is integral to its functionality. Found in various foods such as fermented soybeans, green peppers, and spinach, PQQ is not traditionally classified as a vitamin, but it exhibits vitamin-like properties due to its critical involvement in metabolic processes. One of the most significant features of PQQ is its ability to facilitate cellular energy production through mitochondrial biogenesis, enhancing the synthesis of mitochondria within cells. This action is particularly important as mitochondria are known as the powerhouses of the cell, responsible for producing adenosine triphosphate (ATP), the energy currency vital for cell function.
Apart from its respiratory benefits, Theophylline also affects the cardiovascular system. It can stimulate the heart, leading to an increase in heart rate and force of contraction. This makes it crucial for healthcare professionals to carefully monitor patients, especially those with pre-existing heart conditions, during Theophylline therapy.
Manufacturers must adhere to Good Manufacturing Practices (GMP), which involve a series of guidelines ensuring that products are consistently produced and controlled according to quality standards. This includes rigorous testing and documentation processes that can validate the identity, strength, quality, and composition of APIs before they are used in pharmaceutical products.
