Definitions
- the invention relates to a method for contraception by the administration of trimegestone.
- the invention further relates to pharmaceutical compositions and dosage forms which contain trimegestone.
- Trimegestone (17 ⁇ -[(S)-2-hydroxypropanoyl]-17 ⁇ -methyl-estra-4,9-dien-3-one) is a known prior art gestagen. It may be considered as a very potent progestin with regard to strong endometrial transformation effect and moderate ovulation suppression. The pharmacodynamic profile is very close to progesterone, the natural progestin. Reference may for example be made in this connection to EP-A 007 823. Combinations of trimegestone with oestrogens for contraception are described, for example, in WO 98/04246, WO 98/04265, WO 98/04268 and WO 98/04269. WO 01/37841 discloses the administration of trimegestone in combination with oestradiol for treating the symptoms of the menopause and for preventing post-menopausal osteoporosis.
- oral contraceptive preparations comprise a gestagen in combination with an oestrogen as the hormonal active ingredients, with administration conventionally proceeding for 21-25 days in each 28-day menstrual cycle. Thereafter, either a placebo or nothing at all is administered for 3-7 days, so initiating withdrawal bleeding.
- a contraceptive preparation should, on the one hand, provide good cycle control and, on the other hand, exhibit no or only slight side-effects.
- Cycle control is primarily effected by the oestrogen.
- the cycle controlling effect of the oestrogen in turn may be influenced by the gestagen and hence, the nature and the dose of the gestagen are also important factors to be taken into account.
- Good cycle control is in particular also distinguished by the occurrence of the desired (withdrawal) bleeding, which may inter alia be characterised by
- gestagen/ oestrogen combination is administered either at a constant dose (monophasic) or in a bi- or multiphasic regimen.
- WO 98/04269 discloses a monophasic regimen and WO 98/04265, WO 98/04268 and WO 98/04246 disclose multiphasic regimens, with inter alia 40-500 ⁇ g of trimegestone being administered daily in combination with an oestrogen. While according to A.E. Schindler et al., Maturitas, 2003, 46, S1 , 7-16 the ovulation inhibition dose of trimegestone is 0.5 mg per day p.o., according to WO 98/04269, WO 98/04265, WO 98/04268 and WO 98/04246 the administered daily dose of trimegestone is preferably in the range from 40 to 250 ⁇ g. However, it is at least doubtful whether a daily dose of e.g. 40 ⁇ g trimegestone is sufficient in order to provide and to maintain a reliable contraceptive effect.
- Entirely regular administration is, however, difficult to guarantee for practical reasons. It is known, for example, that a not inconsiderable proportion of women occasionally forget to take the dose intended for a particular day and only catch up on the following day. It may also happen, that the intended dose is administered in the morning on one day and not until the evening on the following day. Similar problems may also arise if the woman vomits after having taken the contraceptive, but before the dose has been completely resorbed.
- the consequent fluctuations in plasma concentration may, as a result of the low dose of the administered active ingredients, possibly fall to values below the minimum threshold concentration which would be necessary to ensure reliable contraception. In such cases, the effectiveness of the contraception cannot always be guaranteed with a minimised active ingredient dose.
- the fluctuations in plasma concentration may furthermore also result in premature onset of (withdrawal) bleeding (intermenstrual bleeding, for example as spotting or breakthrough bleeding).
- trimegestone may in some women result in a plasma concentration which is above the necessary minimum concentration, but in other women, due to faster metabolisation, a higher dose would be necessary in order to ensure effective contraception.
- the object of the invention is to provide a contraceptive method which exhibits advantages over prior art methods. Apart from ensuring effective contraception, the method should ensure good cycle control and exhibit no or at most only slight side- effects, for example no depressive mood effect and no disadvantageous effects on carbohydrate metabolism and lipid or lipoprotein levels. These properties should be relatively insensitive to irregularities in administration of the active ingredients and to intehndividual variations. This object is achieved by the subject matter of the claims.
- trimegestone when trimegestone is administered in combination with an oestrogen for oral contraception, the ratio of gestagen to oestrogen may be varied within relatively broad limits thereby providing a reliable contraceptive effect without consequently giving rise to increased side-effects, such as for example depressive mood effect and disadvantageous effects on carbohydrate metabolism and lipid or lipoprotein levels. It has thus surprisingly been found that the dose of trimegestone may be increased within certain limits without simultaneously also having to increase the dose of the oestrogen in order to maintain the gestagen- oestrogen balance. In this way, side-effects which would otherwise accompany an elevated dose of the oestrogen are prevented.
- the invention relates to a method for contraception comprising preferably oral administration of
