Method would be selective, so no characteristic of the sample or the environment would interfere with the measurement of any analyte or sample property. As the instrument approaches the ideal "analytical black box, " it would be able to recognize that it is examining a sample unlike any it has ever examined before and would respond appropriately. This response could take the form of a request for operator assistance or for more samples of the same type, a "second opinion" analysis by another technique, or a library search for the best step to take. Near-infrared near-IR ; spectrometry with multivariate chemometrics is becoming more and more like this ideal. The purpose of this investigation was to test the hypothesis that near-IR imaging spectrometry permits the identity and composition of large numbers of tablets to be determined simultaneously through blister packs to study stability. Aspirin was selected for study because its breakdown mechanism is well understood and because it is inexpensive. Aspirin tablets can be placed in a blister pack so that breakdown can be initiated easily by placing a small hole in the package and putting the package into a hydrator. Near-IR spectrometry and nonparametric multivariate analysis are a potent combination in solid dosageform analysis, as demonstrated by 1. analysis of intact tablets [1], 2. detection of tampering in gelatin capsules [2], and 3. detection of contamination in drug capsules [3]. Near-IR spectrometry and multivariate analysis has also been used to discriminate between different tablet formulations inside blister packages [4].

JAN-MAR 2005 wish to take an oral contraceptive, w o u l containing at least 50 g ethinyloestradiol, and even then should consider using additional barrier contraception. Levonorgestrel implants are occasionally ineffective in women receiving these AEDs, and medroxyprogesterone injections must be given every 10 rather than 12 weeks. Although lamotrigine does not promote hormonal contraceptive failure, lamotrigine concentrations m ay b contraceptive, allowing possible breakthrough seizures or toxic effects on contraception withdrawal. Pregnancy planning- It is essential that every young woman is aware of the potential harm from medication to her unborn baby. This is especially important in adolescence where at least 30% of pregnancies are unplanned. Ideally, the need for AED should be reconsidered before any planned pregnancy, and the regimen optimised. Folate 5 mg daily may in theory help to prevent neural tube defects associated with valproate treatment, and is recommended for all women taking AEDs who are not t a k measures. Nausea and vomiting in early pregnancy and dilutional effects of medication during pregnancy may upset medication blood c o n unilaterally stop their prescribed m e d pregnancy, without necessarily informing their physician. The indications for assessing blood AED concentrations during pregnancy remain a matter of debate. Te r a potentially teratogenic. Prospective observational data from the UK Epilepsy and Pregnancy Register show an alarming trend towards valproate being more associated with major congenital malformations than either carbamazepine or lamotrigine. There are also suggestions of increased neurodevelopmental delay among children exposed in utero to valproate. Consequently, sodium valproate should no longer be regarded as a first choice AED in young women. A case could be made to target those on valproate for review, aiming to shape informed decisions about their long term.

100% in the endocrine therapy group, in which 68 patients regained menses after goserelin administration was discontinued. Currently, it is not known which of the two activities--the direct cytotoxic effect or the "indirect" endocrine manipulation--is more important and whether or not they diverge in different tumor cells, such as in hormone-responsive and -unresponsive breast cancer cells.18 The adjuvant setting has shown that permanent induction of amenorrhea, by way of surgical or radiologic castration, is a highly effective tool in breast cancer patients younger than 50 years of age. Overview data have argued in favor of a long-term beneficial effect arising from ovariectomy, yet direct comparisons between adjuvant chemotherapy CMF ; and ovariectomy have suggested no difference in long-term outcomes.19-21 The EBCTCG overview showed in several ways that the issue of adjuvant endocrine therapy remains incompletely resolved.6 Although ovariectomy-versus-nil comparisons seem to evidence the high therapeutic impact of ovarian ablation, the former method seems to add little or nothing to the benefits of chemotherapy in the framework of trials applying chemotherapy with or without ovariectomy. The data are also substantiated by results from the Eastern Cooperative Oncology Group, according to which the addition of goserelin to cyclophosphamide, doxorubicin, and fluorouracil CAF ; failed to show a significantly beneficial effect.22 In the metastatic situation, outcomes have not differed between ovariectomy by surgery or radiotherapy and medically induced amenorrhea with luteinizing hormonereleasing hormone analogs. However, the addition of tamoxifen to such analogs was shown to be superior to either non drug-based intervention.23, 24 When ABCSG Trial 5 was launched in 1990, the above data were largely unknown. It was well established that adjuvant chemotherapy and ovariectomy represented effective adjuvant treatment modalities. Likewise, tamoxifen was recognized as adjuvant treatment in postmenopausal women with hormoneresponsive breast cancer, but at that time it showed a limited effect, if any at all, in premenopausal patients. This was partly explained by high endogenous estradiol serum blood levels, which occupy the steroid hormone receptor and render tumor cells resistant to antiestrogens. The hypothesis guiding Trial 5 was that decrease of estrogen serum blood levels by the agency of goserelin administration should facilitate antiestrogenic tamoxifen ; action. We therefore chose to compare this combination with CMF, the chemotherapeutic regimen of choice at that time. Arguing in favor of the predictive value of the steroid hormone receptor, we furthermore decided to limit patient selection to women with hormone-responsive tumors. Two other clinical trials have been based on similar designs, one using the same polychemotherapy25 and the other restricted to node-positive tumors treated with fluorouracil, epirubicin, and cyclophosphamide.26 Hampered by a somewhat small number of participants, the former trial failed to detect a statistically significant difference between combination endocrine treatment and CMF. The latter showed a clear yet insignificant trend in favor of endocrine treatment. Moreover, the combination of goserelin and tamoxifen has more recently been assessed, in addition to CAF, by an intergroup investigation in node-positive, receptor-positive patients.22 As mentioned above, it was shown that the addition of goserelin to CAF failed to improve the rate of disease-free survival at 5 years, whereas tamoxifen added to goserelin and CAF significantly improved the outcome in pa and glibenclamide.

This study supports an earlier investigation [14], that at the time of the estradiol-induced LH surge, there is a clear concomitant GH surge. It is important that this is the first immunocytochemical study to describe the distribution of GHRH neurons in the sheep and to provide evidence that the effect of estradoil on GH output is not through a direct action on GHRH neurons. Moreover, any direct effect on the somatotrope through the ER is likely to be small. This is the first study reporting the distribution of immunoreactive GHRH neurons in the ewe and, in agreement with several other species; namely, rats [18, 19], guinea pigs [20], mice [39], cats [40], pigs and cows [41], monkeys [22] and humans [42], immunoreactive GHRH perikaryia are restricted to the arcuate and ventromedial nucleus of the hypothalamus. This distribution corresponds to that shown for the GHRH mRNA in the ewe [43]. To our knowledge, this is also the first study in any species to use immunocytochemical methods to determine whether GHRH neurons express ERs. This absence of steroid receptors in GHRH perikaryia agrees with a recent study in the male rat showing no colocalization with androgen receptors [44]. However, our discovery that GHRH neurons do not express ER does not concur with an autoradiographic study in the female rat in which up to a third of GHRH neurons in the central portion of the arcuate nucleus were reported to concentrate [3H]estradiol within the. Providing five years of contraceptive protection for 100 women, using continuation rates of 85100% for the implant and the injectable. When the annual continuation rate is close to 100%, the five-year cost of the implant for the hypothetical cohort of 100 women appears to be around $50, 000, while the cost of injectable use is approximately $70, 000. Thus, when continuation rates are relatively high, the implant is the more cost-effective option. However, the cost of the implant rises significantly as continuation rates decrease, such that if implant continuation rates fall much below 95%, injectable use becomes more cost-effective. One study found an annual continuation rate for the implant of around 92%, 18 but two others found rates of below 90%.19 and glucovance and estradiol, for instance, 17 beta estradiol.

MSA Reduces ERA Protein Levels in TamoxifenSensitive and -Resistant Cell Lines We previously showed that ERa protein and mRNA down-regulation was likely a major mechanism by which MSA inhibited ER signaling in MCF-7 cells; MSA had no effect on ERh mRNA.4 These experiments were extended to determine whether MSA altered ERa protein in both tamoxifen-sensitive and -resistant cells. In addition, the effect of es6radiol or 4-hydroxytamoxifen alone or in combination with MSA on ERa protein expression was also assessed. Due to very low expression of ERa in HEC1A cells, the Western blot analysis was inconclusive data not shown ; .

Nafisa Momin Department of Family Medicine, Aga Khan University, Karachi, Pakistan Emergency contraception can be used to prevent pregnancy after known or suspected failure of birth control or after unprotected intercourse. Its use is limited largely because of lack of knowledge. Both hormonal and non-hormonal methods of emergency contraception are available. It is most effective when initiated within 72 hours after unprotected intercourse. The mechanism of action may vary depending on the day of the menstrual cycle on which treatment is started. Emergency postcoital contraception is regarded by many as an abortifacient because it is taken after, rather than before, intercourse but it is important to remember that prevention of pregnancy before implantation is contraception and not abortion. Despite the large number of women who have received emergency contraception, there have been no reports of major adverse outcomes. If a woman becomes pregnant after using emergency contraception, she may be reassured about the lack of negative effects emergency contraception has on fetal development. Family physicians should inform their patients of reproductive age about the availability and efficacy of emergency postcoital contraception to avoid unplanned pregnancy. Key words: Emergency contraception, postcoital contraception, side effects INTRODUCTION Emergency postcoital contraception, a method used to prevent pregnancy after unprotected sexual intercourse, is a highly effective but underutilized birth control option. Two hormone regimens, ethinyl estradiol 100 g ; with levonorgestrel 0.5 mg ; or high-dose levonorgestrel 0.75 mg ; , given within 72 hours of intercourse and repeated 12 hours later, are widely available for this purpose. There are other options but with limited availability. The use of safe, effective emergency postcoital contraceptive methods could decrease unintended pregnancies. DEFINITION Emergency contraception also known as postcoital contraception and morning after pills ; typically refers to the administration of drugs to prevent pregnancy in women who have had recent unprotected intercourse, or to those who have had a failure of another method of contraception e.g., broken condom ; .1 PROBABILITY OF CONCEPTION The probability of conception after a single act of intercourse has been calculated to be about 33 percent per cycle if intercourse occurs on average every other day; if it occurs only once per week, the chance of pregnancy is only 15 percent1. Conception occurs only around the time of ovulation. Surprisingly, the number of days of the menstrual cycle during which a woman is fertile i.e., on which conception could result if intercourse occurred ; has been difficult to quantify. Physicians must understand the probability of conception when emergency contraception is considered. The average fertile period for a woman lasts only six days per menstrual cycle and ends the Medicine Today Vol. 4 No. 2 Apr Jun 2006 day she ovulates. Unprotected sex three days before ovulation results in an estimated 15% pregnancy rate; one or two days before ovulation, a 30% rate; and on the day of ovulation, an estimated 12% rate. Sperm can survive in the female up to five days, and the mature egg may be fertilized over a 24-hour period. The time period from ovulation to implantation is about seven days.2 COMMONLY USED EMERGENCY CONTRACEPTIVES The options currently available include an estrogen-progestin combination ethinyl estradiol with levonorgestrel ; , progestin alone levonorgestrel ; , the antiprogestin synthetic steroid RU 486 mifepristone ; and the copper Intrauterine Device IUD ; . MECHANISM OF ACTION Estrogen and progesterone, alone or in combination, inhibit or delay ovulation. However, in human studies the evidence is less clear about cumulative effects on fertilization, gamete transport, the endometrium, functioning of the corpus luteum or implantation. Histologic alterations and biochemical changes are demonstrated, although they may not be significant enough to prevent pregnancy at any given point in the cycle. These hormones will not dislodge an implanted embryo.1.
Calcium channel blockers: amlodipine, diltiazem, felodipine, isradipine, nicardipine, nifedipine, nimodipine, nisoldipine, and verapamil - serum concentrations of these medicines may be increased, which could increase their activity and toxicity. Dexamethasone: may induce CYP3A4 and decrease plasma concentrations of amprenavir. Erectile dysfunction agents: based on data for ritonavir and other protease inhibitors, plasma concentrations of PDE5 inhibitors eg. sildenafil ; are expected to substantially increase when co-administered with fosamprenavir and ritonavir and may result in an increase in PDE5 inhibitor associated adverse events. Concomitant use is not recommended see Precautions ; Fluticasone propionate interaction with ritonavir ; : Systemic corticosteroid effects including Cushing's syndrome and adrenal suppression have been reported in patients receiving ritonavir and inhaled or intranasally administered fluticasone propionate; this interaction is also expected with other corticosteroids metabolised via the P450 3A pathway see Warnings and Precautions ; . Therefore, concomitant use of fluticasone propionate and ritonavir should be avoided, unless the potential benefit to the patient outweighs the risk of systemic corticosteroid side effects. Halofantrine: plasma concentrations of halofantrine may increase when co-administered with fosamprenavir and ritonavir and may result in an increase in halofantrine associated adverse events such as cardiac arrhythmia. Concomitant use is not recommended see Warnings and Precautions ; . HMG-CoA reductase inhibitors: HMG-CoA reductase inhibitors which are highly dependent on CYP3A4 for metabolism, such as atovastatin, lovastatin and simvastatin, are expected to have markedly increased plasma concentrations when co-administered with fosamprenavir and ritonavir. Since increased concentrations of HMG-CoA reductase inhibitors may cause myopathy, including rhabdomyolysis, the combination of these medicinal products with fosamprenavir and ritonavir is not recommended. When used with fosamprenavir and ritonavir, doses of atovastatin no greater than 20 mg day should be administered, with careful monitoring for atovastatin toxicity. The metabolism of pravastatin and fluvastatin is not dependent on CYP3A4, and interactions are not expected with protease inhibitors. If treatment with an HMG-CoA reductase inhibitor is indicated, pravastatin or fluvastatin is recommended see Precautions ; . Immunosuppressants: plasma concentrations of cyclosporin, rapamycin and tacrolimus may be increased when co-administered with fosamprenavir and ritonavir. Therefore, frequent therapeutic concentration monitoring is recommended until levels have stabilised. Methadone: amprenavir and ritonavir both decrease plasma concentrations of methadone. Therefore, when methadone is co-administered with fosamprenavir and ritonavir, patients should be closely monitored for opiate abstinence syndrome, with concomitant monitoring of methadone plasma levels see Precautions ; . Paroxetine: plasma concentrations of paroxetine may be significantly decreased when coadministered with fosamprenavir and ritonavir. Any paroxetine dose adjustment should be guided by clinical effect tolerability and efficacy ; . Steroids: co-administration of fosamprenavir 700 mg twice daily + ritonavir 100 mg twice daily with Brevinor ethyinly estradiol EE ; 0.035 mg norethisterone NE ; 0.5 mg ; once.
They need to return it to prescription only, especially since those who truly need the drug need to see doctors about other health problems that would inevitably be linked to their weight issues, for example, estradiol levels. Support: To help patients and their families cope with scleroderma through mutual support programs, peer counseling, physician referrals, and educational information. Education: To promote public awareness and education through patient and health professional seminars, literature, and publicity campaigns. Research: To stimulate and support research to improve treatment and ultimately find the cause of and cure for scleroderma and related diseases and famotidine.
