[Examination of hormonal contraceptives by enzyme induction (author's transl)]
Abstract:
The influence of drug stimulated biotransformation on the biological effectiveness of two different contraceptives (Deposition and Gravistat) was observed.--Phenobarbital, a potent enzyme inducer, is known to increase the metabolism of steroid hormones, including estrogens and progrestogens. -- The clinical symptoms of drug mediated enzyme induction of hormonal steroid contraceptives are dysfunctional bleedings. This phenomenon is discussed.

Hormonal Regulation
Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.
Enzyme Inhibition
Inhibitors are molecules that reduce enzyme activity by binding to the enzyme. In a normally functioning cell, enzymes are regulated by a variety of inhibitors. Drugs and other toxins can also inhibit enzymes. Some inhibitors bind to the enzyme’s active site, while others inhibit enzymatic activity by binding to other sites on the protein structure.
