Succinimide a chemical compound used in different organic syntheses. Succinimides are compounds that contain the succinimide group, a pharmacophore, responsible for the anticonvulsant effect. Succinimides used to control certain seizures in the treatment of epilepsy, by acting on the central nervous system.

Lisuride (DOPERGIN®), a highly active dopaminergic ergot derivative with prolactin-lowering properties, has a pronounced affinity for dopamine receptors. It may also act as an agonist at some serotonin receptors. Lisuride (DOPERGIN®) is concentrated within the pituitary where it acts on dopamine receptors which inhibit prolactin release. It can be used in the clinical conditions where a dopaminergic or prolactin-lowering effect is needed.

Metergoline is a psychoactive drug of the ergoline chemical class which acts as a ligand for various serotonin and dopamine receptors. Metergoline is an antagonist at various 5-HT receptor subtypes at a relatively low concentration and an agonist at dopamine receptors. Its use has been studied in various clinical settings such as a treatment for seasonal affective disorder, prolactin hormone regulation due to its inhibitory effect on prolactin release premenstrual dysphoric disorder in women and antianxiety treatment

Norelgestromin, the progestin, is the active metabolite of norgestimate and is structurally related to 19-nortestosterone. Norgestimate and norelgestromin mimic the physiologic effects of progesterone at the progesterone receptor. Johnson & Johnson developed an adhesive female contraceptive patch that contains ethinylestradiol (0.75mg) and the progestogen norelgestromin (6mg). his product is a combination contraceptive acting via the inhibition gonadotropins. Its primary mechanism of action involves the suppression of ovulation, including changes in the cervical mucus and endometrium. The patch delivers a continuous flow of hormones through the skin and into the bloodstream. The contraceptive patch is available in countries worldwide.

Norgestimate is a steroidal progestin of the 19-nortestosterone group that is used in combination with ethinylestradiol as an oral contraceptive and for treatment of acne. and in combination with estradiol in menopausal hormone replacement therapy. Norgestimate shows high selectivity for the progesterone receptor and low androgenic activity.

Clomiphene (CLOMID®) is a triphenyl ethylene stilbene derivative which is an estrogen agonist or antagonist depending on the target tissue. It is an orally administered, nonsteroidal, ovulatory stimulant. Clomiphene (CLOMID®) is a mixture of two geometric isomers [cis (zuclomiphene) and trans (enclomiphene)] containing between 30% and 50% of the cis-isomer. Clomiphene (CLOMID®) initiates a series of endocrine events culminating in a preovulatory gonadotropin surge and subsequent follicular rupture. The first endocrine event in response to a course of clomiphene therapy is an increase in the release of pituitary gonadotropins. This initiates steroidogenesis and folliculogenesis, resulting in growth of the ovarian follicle and an increase in the circulating level of estradiol. Following ovulation, plasma progesterone and estradiol rise and fall as they would in a normal ovulatory cycle.
