Consumption of calcium, aluminium, or magnesium with oral EMP can markedly impair its bioavailability due to diminished absorption from the intestines, and this may interfere with its therapeutic effectiveness at low doses.Following a single oral dose of 420 mg EMP in men with prostate cancer, maximal levels of estromustine were 310 to 475 ng/mL (475,000 pg/mL) and occurred after 2 to 3 hours. Estradiol levels with 280 mg/day oral EMP have been found to increase to very high concentrations within one week of therapy. In one study, levels of estradiol were over 20,000 pg/mL after 10 days, were about 30,000 pg/mL after 30 days, and peaked at about 40,000 pg/mL at 50 days. Another study found lower estradiol levels of 4,900 to 9,000 pg/mL during chronic therapy with 560 mg/day oral EMP. An additional study found estradiol levels of about 17,000 pg/mL with 140 mg/day oral EMP and 38,000 pg/mL with 280 mg/day oral EMP. The circulating levels of estradiol and estrone during EMP therapy have been reported to exceed normal levels in men by more than 100- and 1,000-fold, respectively. Levels of estramustine and estradiol in the circulation are markedly lower than those of estromustine and estrone, respectively, with a ratio of about 1:10 in both cases. Nonetheless, estradiol levels during EMP therapy appear to be similar to those that occur in mid-to-late pregnancy, which range from 5,000 to 40,000 pg/mL. No unchanged EMP is seen in the circulation with oral administration.The pharmacokinetics of EMP are different with intravenous injection.
Midol is a brand of over-the-counter analgesic drugs marketed for menstrual cramping and other effects related to premenstrual syndrome and menstruation. Various subbrands are formulated using different active ingredients. Midol is distributed by Bayer. Midol was originally sold in 1911 as a headache and toothache remedy that was considered safer because it did not use the narcotics typically used at the time. It was then promoted as a cure for hiccups claiming it controlled spasms, and finally as a remedy for menstrual cramps and bloating. A formulation sold in the 1980s was made with the sympathomimetic cinnamedrine. It had been reported to have abuse potential as an appetite suppressant and sympathomimetic agent. The "Midol Complete" formulation consists of:

Acetaminophen 500 mg (pain reliever)
Caffeine 60 mg  (stimulant)
Pyrilamine maleate 15 mg (antihistamine)The "Extended Relief" formulation consists of:

Naproxen sodium 220 mg (NSAID, pain reliever/fever reducer)The "Teen" formulation consists of:

Acetaminophen 500 mg (pain reliever)
Pamabrom 25 mg (diuretic)The "Liquid Gels" formulation consists of:

Ibuprofen 200 mg (NSAID, pain reliever)The "PM" formulation consists of:

Acetaminophen 500 mg (pain reliever)
Diphenhydramine citrate 38 mg (sedative antihistamine)There are concerns drugs like Midol, which is an NSAID, increases risk of bleeding, kidney damage and has other negative effects on cardiovascular system. References
