ARTICLE INFO ABSTRACT Received: 11 Nov 2017 The electrochemical behaviour of clomifene was studied and determined in pharmaceutical Accepted: 18 Dec 2017 formulations. The drug of clomifene was electrochemically examined by cyclic and differential pulse voltammetry using a glassy carbon electrode (GCE). The obtained results showed that, the Britton Robinson buffer with pH 4.0 was the best medium for reduction of clomifene on the glassy carbon electrode at the peak potential -1.01 V. The range of linearity was found to be from 0.20 μg mL-1 to 60.0 μg mL-1 (R2 = 0.994) with limit of detection (LOD) 0.168 μg mL-1 and limit of quantification (LOQ) was 0.511 μg mL-1. Differential pulse voltammetric method was successfully applied for the electrochemical determination of clomifene in pharmaceutical formulations ______ Keywords: Clomifene, drug, voltammetry, pharmaceutical formulations. 1.

Clomifene Pharmacokinetic Data Bioavailability High (>90
Clomifene Pharmacokinetic data Bioavailability High (>90%) Metabolism Hepatic (with enterohepatic circulation) Half-life 5-7 days Excretion Mainly renal, some biliary Clomifene (INN) or clomiphene (USAN) (trademarked as Androxal, Clomid and Omifin) is a selective estrogen receptor modulator (SERM) that increases production of gonadotropins by inhibiting negative feedback on the hypothalamus. This synthetic drug comes supplied as white, round tablets in 50 mg strength only. It has become the most widely prescribed of all fertility drugs. It is used in the form of its citrate to induce ovulation. Use in female infertility It is used mainly in female infertility, in turn mainly as ovulation induction to reverse oligoovulation or anovulation such as in infertility in polycystic ovary syndrome, as well as being used for ovarian hyperstimulation, such as part of an in vitro fertilization procedure. In April 1989, a patent was awarded to Yale University Medical researchers Dr. Florence Comite and Dr. Pamela Jensen for the use of clomiphene to predict fertility in women. A woman capable of sustaining pregnancy would develop denser bone mass while on clomiphene; the bone mass increase would be predictive of fertility, and the changes could be detected on a CT scanner. Mode of action Clomifene inhibits estrogen receptors in hypothalamus, inhibiting negative feedback of estrogen on gonadotropin release, leading to up-regulation of the hypothalamic–pituitary–gonadal axis. Zuclomifene, a more active isomer, stays bound for longer periods of time. The drug is non-steroidal. In normal physiologic female hormonal cycling, at 7 days past ovulation, high levels of estrogen and progesterone produced from the corpus luteum inhibit GnRH, FSH and LH at the hypothalamus and anterior pituitary. -
