Drug interactions with oral contraceptives: compilation and analysis of an adverse experience report database.

Over 700 alleged OC/drug interactions were reported for antituberculous drugs, other antibiotics, anticonvulsants, antidepressants, and analgesics. Fewer than ten reports of OC/drug interactions were found involving antihistamines, thyroid hormone, vitamin C, antacids, ulcer medication, or diuretics. These may represent a set of OC/drug interaction problems that need to brought into medical awareness. Pregnancy is the first event reported when OCs appear to interact with another drug. However, menstrual disturbances are reported more often. BTB is the most frequently reported menstrual disturbance: it has been considered a warning signal that OC efficacy may be compromised. In such circumstances, contraceptive backup may be warranted. Reports of interference with OC efficacy have been most common for drugs used to treat tuberculosis, epilepsy, and depression, so patients and their physicians should be aware of potential problems. However, the average woman is more likely to encounter antibiotics, analgesics, and antihistamines, and current package inserts contain appropriate warnings. In recent years, prescriptions for low-estrogen OCs have outnumbered those for high-dose preparations. Many physicians became concerned that there was an increased risk of OC drug failure with the low-dose products. The database does not seem to suggest that this has happened. The dose of estrogen is not correlated with total adverse experience reports, time of appearances of the first adverse experience reports, or rate of reporting of the interactions. Likewise, reports of potential interactions with menstrual disturbances are not correlated with lower estrogen doses in OCs. There is, however, an association between low-estrogen OCs and recently reported pregnancies attributed to OC/drug interactions.(ABSTRACT TRUNCATED AT 250 WORDS)

Cycle control and side effects of a new combiphasic oral contraceptive regimen.

In a multicentre study 882 women were treated during a total of 12,850 cycles with a new combiphasic contraceptive: CTR 24. The study period was 18 cycles. The combiphasic preparation CTR 24 contains 25 micrograms desogestrel (CAS 54024-22-5) plus 40 micrograms ethinylestradiol (CAS 57-63-6) daily for the first 7 days followed by the combination of 125 micrograms desogestrel and 30 micrograms ethinyl-estradiol daily for the subsequent 15 days. The bleeding patterns were analysed over pill cycles and a comparison was made between starters and switchers. The cycle control of the combination was very good. The side effect profile was favourable.
