Promestriene (3-propyl ethyl, 17B-methyl estradiol) is a synthetic estrogen analog, which is used in topical estrogen therapy. Promestriene’s potential for treating vaginal atrophy symptoms associated with aromatase inhibitor treatment would be precluded if its minimal absorption leads to estrogen-like effects on cell proliferation and estrogen-responsive gene expression. The concern with absorbed vaginal estrogens or estrogen analogs is that they activate occult sites of residual breast cancer or negate the tumor suppressive effects of aromatase inhibitor adjuvant therapy. Promestriene has been studied in phase IV of the clinical trial on improvement of hormonal cytology, local and systemic climacteric complaints, as well as its endometrial security in patients with vaginitis atrophic pelvic; organ prolapse and endometrial hyperplasia. It has been also studied in phase III of the clinical trial in the post-operative patients with hypospadias. In addition, promestriene was in phase IV of the clinical trial to study its treatment of patients with vaginosis, bacterial, but that studied was terminated.

Meladrazine is a drug used in urology as an antispasmodic. Meladrazine acts on the central nervous system as a polysynaptic inhibitor. Its usefulness in treating spasticity in patients with multiple sclerosis is well known. As many of these patients have bladder problems, a coincidental beneficial effect on uninhibited bladders has been discovered. Meladrazine caused a high incidence of side effects; therefore, treatment with terodiline separately is recommended for geriatric patients who have severe motor urge incontinence.

Dapoxetine hydrochloride is a selective serotonin reuptake inhibitor (SSRIs). In addition, dapoxetine inhibits voltage-dependent K+ (Kv) channels in a dose-, time-, use-, and state (open)-dependent manner, independent of serotonin reuptake inhibition. Dapoxetine is indicated for the treatment of premature ejaculation (PE) in men 18 to 64 years of age, who have all of the following: persistent or recurrent ejaculation with minimal sexual stimulation before, on, or shortly after penetration and before the patient wishes; and marked personal distress or interpersonal difficulty as a consequence of PE; and poor control over ejaculation. The mechanism of action of dapoxetine in premature ejaculation is presumed to be linked to the inhibition of neuronal reuptake of serotonin and the subsequent potentiation of the neurotransmitter's action at pre- and post-synaptic receptors. The most common effects when taking dapoxetine are nausea, dizziness, dry mouth, headache, diarrhea, and insomnia.

CV-205502 (Quinagolide, Norprolac), a small molecule, dopamine 2-receptor agonist was developed by Novartis for the treatment of prolactinoma and hyperprolactinaemia. It is is a long-acting dopamine agonist with potent D2 and weak D1 activity. Quinagolide exists as a racemate and its relevant clinical activity is mediated predominantly by the (-) enantiomer. It is typically present in the hydrochloride salt form and is marketed as oral tablets under the brand name Norprolac contained as a racemate. Quinagolide is currently available in several countries including Canada, but not approved for treatment in the United States. Owing to its dopaminergic action, the drug exerts a strong inhibitory effect on the secretion of the anterior pituitary hormone prolactin, but does not reduce normal levels of other pituitary hormones. Long-term treatment with Norprolac was found to reduce the size or limit the growth of prolactin-secreting pituitary macroadenomas. In some patients the reduction of prolactin secretion may be accompanied by short- lasting, small increases in plasma growth hormone levels, the clinical significance of which is unknown. As a specific inhibitor of prolactin secretion with a prolonged duration of action, Norprolac has been shown to be effective and suitable for once-a- day oral treatment of patients presenting with hyperprolactinaemia and its clinical manifestations such as galactorrhoea, oligomenorrhoea, amenorrhoea, infertility and reduced libido.

Moxestrol (11β-methoxy-17-ethynyl-estradiol) is estrogen receptor agonist. It is used in the studies of estrogen receptor activity and distribution. Moxestrol is rapidly metabolized by the liver. Hydroxylation was the main transformation pathway. Moxestrol yielded metabolites hydroxylated (or methoxylated) at C-2, C-15 and C-16, but not at C-6, and also gave rise to D-homo derivatives. It was considered as a potentially effective drug in the treatment of postmenopausal disturbances.

Cyclofenil is a anti-estrogen drug developed for the treatment of female infertility and for induction of ovulation. Cyclofenil exerts its action by binding to estrogen receptor beta and demonstrates agonism or antagonism depending on tissues type. The drug was withdrawn from the market due to high risk of hepatotoxicity.

Lasofoxifene is an active component of Fablyn. Fablyn is used for the treatment of osteoporosis in postmenopausal women. Lasofoxifene is a nonsteroidal selective estrogen receptor modulator. Lasofoxifene has no effect on CYP2E1- or CYP2D6-mediated drug metabolism and should not affect drugs metabolized by other cytochrome P450 isoenzymes. Common adverse reactions considered to be related to Fablyn therapy were muscle spasms, hot flush and vaginal discharge. Lasofoxifene approved in the EU in 2009 is now withdrawn from use in the European Union.

Terguride (INN), also known as trans-dihydrolisuride, is a serotonin receptor antagonist and dopamine receptor agonist of the ergoline family. Terguride is approved for and used in the treatment of hyperprolactinemia. Terguride is an oral, potent antagonist of 5-HT2B and 5-HT2A (serotonin) receptors. Serotonin stimulates the proliferation of pulmonary artery smooth muscle cells and induces fibrosis in the wall of pulmonary arteries. Together, this causes vascular remodeling and narrowing of the pulmonary arteries. These changes result in increased vascular resistance and PAH. Due to the potential anti-proliferative and anti-fibrotic activity of terguride, this potential medicine could offer the hope of achieving reversal of pulmonary artery vascular remodeling and attenuation of disease progression. In May 2008, terguride was granted orphan drug status for the treatment of pulmonary arterial hypertension. In May 2010 Pfizer purchased worldwide rights for the drug.

EPIMESTROL is a synthetic steroid with estrogenic activity. It was used for the treatment of chronic anovulation and corpus luteum deficiency.

Omoconazole is an azole antifungal drug, is used to treat candidiasis; dermatophytes and Pityriasis Versicolor
