title: Observations with a tri-phasic oral contraceptive (Tri-Regol) in everyday clinical practice.
abstract: The theoretical general principles of triphasic oral contraception are discussed in the introduction. This method, which is the closest to a physiological dosage, seems to be the most advantageous today. International data and the advantages and wide indication field of such "step-up" tablets are also discussed. The observations with the Hungarian Tri-Regol tablet are described in detail. In the course of controlling 355 cycles of 79 women pregnancy was not observed, the tablets were well tolerated by the women-except for some milder side-effects. The use of Tri-Regol needed not be discontinued due to, any unwanted effect or complication. The rate of intermenstrual bleeding was very low, and the triphasic therapy proved to be beneficial in case of manifesting cycle disorders or if the change of the contraceptive tablet became necessary because of intolerance. According to the opinion of the authors the oral contraceptive Tri-Regol is today's drug of choice due to its reliable ovulation inhibitory action, low hormone content, and favourable tolerability.
