Mechanism Of Action
Aminobenzoate potassium is considered to be a member of the vitamin B complex family. The mechanism by which it exerts antifibrotic effects is not known. It has been suggested that the antifibrosis action is due to its mediation of increased oxygen uptake at the tissue level. Fibrosis is believed to occur from either too much serotonin or too little monoamine oxidase activity over a period of time. Monoamine oxidase (MAO) requires an adequate supply of oxygen to function properly. By increasing oxygen supply at the tissue level, aminobenzoate potassium may enhance MAO activity and prevent or bring about regression of fibrosis.
Pharmacokinetics
Aminobenzoate potassium is administered orally. It is considered a member of the B vitamin complex family and metabolism is similar to that seen with food. Excretion is through renal function.
Oral RouteAminobenzoate potassium is considered a member of the B vitamin complex family and, thus, absorption is similar to that seen with food.
Pregnancy And Lactation
An FDA pregnancy risk category classification is not available for aminobenzoate potassium. According to the manufacturer, safe and effective use during pregnancy has not been established.
According to the manufacturer, safe and effective use during breast-feeding has not been established. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding infant experiences an adverse effect related to a maternally ingested drug, healthcare providers are encouraged to report the adverse effect to the FDA.
