Terodiline is a racemic compound, and its main indication was detrusor instability syndrome. With effects on detrusor muscles, terodiline was used for bladder incontinence. Terodiline has both anticholinergic and calcium antagonist properties and, as a result, effectively reduces abnormal bladder contractions caused by detrusor instability. When administered to adult patients with urge incontinence (generally as a 25mg twice-daily dose) terodiline reduces diurnal and nocturnal micturition frequency and incontinence episodes. The (R)-enantiomer of terodiline (R( )-terodiline) can trigger cardiovascular toxicities, such as LQTS and TdP, which led to its withdrawal in 1991. Terodiline under the brand name Micturin was licensed and marketed in the United Kingdom, in 1986, for the management of a specific form of urinary incontinence, detrusor instability. It was eventually marketed in 20 other countries, mainly in Europe and Japan, but not the United States of America.

Otilonium is a musculotropic spasmolytic agent belonging to the family of quaternary ammonium derivatives and successfully used in the treatment of patients affected by Irritable bowel syndrome (IBS) due to its specific pharmacokinetic and pharmacodynamic properties. The positive polarity of the head of the Otilonium molecule determines the main pharmacokinetic property of this drug: a minimal systemic absorption and the consequently high safety profile. Studies on animal models revealed a specific Otilonium accumulation in colonic circular muscle at therapeutic µm concentrations, while its plasma levels were 1000 times lower, together with a poor penetration of the drug in the central nervous system. Consistently, after oral administration to healthy volunteers, the Otilonium plasmatic concentration was very low, less than 1% of the drug was eliminated by urine, and 97% was eliminated by feces. Recent clinical studies showed comparable safety and tolerability for Otilonium and placebo. Otilonium was shown to inhibit the main patterns of human sigmoid motility in vitro, including: the tone of smooth muscle cells (SMCs); the rhythmic phasic contractions induced by the interstitial cells of Cajal; and the strong contractions induced by stimulation of enteric motor neurons mainly by blocking the calcium influx through L-type calcium channels on SMCs. Recent in vitro studies using cultured human colonic SMCs to further assess the musculotropic spasmolytic properties of Otilonium confirmed that this drug causes smooth muscle relaxation through the inhibition of voltage-gated calcium channels (L-type > T-type) and the inhibition of muscarinic and tachykinergic effects.

Huperzine A is a plant alkaloid derived from Club moss plant, Huperzine serrata, which is a member or the Lycopodium species. Huperzine-A is in phase III clinical trial in the USA (Alzheimer disease) and is available as a dietary supplement. It selectively and reversibly inhibits acetylcholinesterase. Huperzine A is also a NMDA receptor antagonist, which protects the brain against glutamate induced damage, and it increases nerve growth factor levels. Huperzine A is used for Alzheimer's disease, memory and learning enhancement, and age-related memory impairment. It is also used for treating a muscle disease called myasthenia gravis, for increasing alertness and energy, and for protecting against agents that damage the nerves such as nerve gases. It can cause some side effects including nausea, diarrhea, vomiting, sweating, blurred vision, slurred speech, restlessness, loss of appetite, contraction and twitching of muscle fibers, cramping, increased saliva and urine, inability to control urination, high blood pressure, and slowed heart rate. Various medications used for glaucoma, Alzheimer's disease, and other conditions (Cholinergic drugs) interacts with Huperzine A.

Indirubin is derived from the Indigo Plant (Isatis Root, Isatis Leaf). It is used as part of a traditional Chinese herbal prescription called Dang Gui Long Hui Wan, to treat chronic myelogenous leukemia (CML). Indirubin inhibits DNA synthesis in several cell lines, in a cell-free assay and in vivo in rats with Walker-256 sarcoma. A weak binding of indirubin to DNA in vitro has been described. Indirubin inhibited all cyclin-dependent kinases (1,2,4,5) almost equally. Indirubin has been approved for clinical trials against chronic myelocytic and chronic granulocytic leukaemia. A few studies show that Indirubin is effective against psoriasis. Mild to severe nausea, vomiting, abdominal pain, diarrhea, headache, and edema are reported adverse events of Indirubin. Long-term oral ingestion has also occasionally been associated with hepatitis, pulmonary arterial hypertension and cardiac insufficiency.

Trimebutine [3,4,5-trimethoxybenzoic acid 2-(dimethylamino)-2-phenylbutylester] is a noncompetitive spasmolytic agent. The actions of trimebutine on the gastrointestinal tract are mediated via (i) an agonist effect on peripheral mu, kappa and delta opiate receptors and (ii) release of gastrointestinal peptides such as motilin and modulation of the release of other peptides, including vasoactive intestinal peptide, gastrin and glucagon. Trimebutine attenuated colonic motility mainly through the inhibition of L-type Ca(2+) channels at higher concentrations, whereas, at lower concentrations, it depolarized membrane potentials by reducing BK(ca) currents, resulting in the enhancement of the muscle contractions.Trimebutine accelerates gastric emptying, induces premature phase III of the migrating motor complex in the intestine and modulates the contractile activity of the colon. It is indicated for the treatment and relief of symptoms associated with the irritable bowel syndrome (spastic colon); and in postoperative paralytic ileus in order to accelerate the resumption of the intestinal transit following abdominal surgery.

Atosiban (brand name Tractocile) is a competitive antagonist of human oxytocin at receptor level. In rats and guinea pigs, atosiban was shown to bind to oxytocin receptors, to decrease the frequency of contractions and the tone of the uterine musculature, resulting in a suppression of uterine contractions. Atosiban was also shown to bind to the vasopressin receptor, thus inhibiting the effect of vasopressin. Tractocile is indicated to delay imminent pre-term birth in pregnant adult women with: − regular uterine contractions of at least 30 seconds duration at a rate of ≥ 4 per 30 minutes − a cervical dilation of 1 to 3 cm (0-3 for nulliparas) and effacement of ≥ 50% − a gestational age from 24 until 33 completed weeks − a normal foetal heart rate. Atosiban does not have U.S. Food and Drug Administration (FDA) approval for use in the United States.

Pralmorelin [GPA 748, GHRP 2, growth hormone-releasing peptide 2, KP-102 D, KP 102 LN] is an orally active, synthetic growth hormone-releasing peptide from a series of compounds that were developed by Polygen in Germany and Tulane University in the US. The use of pralmorelin as a diagnostic agent for GH deficiency is based on its ability to markedly increase plasma levels of GH in healthy subjects irrespectively of gender, obesity or age. However, in patients with GH deficiency, the effect of pralmorelin on GH levels is significantly lower compared with healthy controls. Pralmorelin is marketed under the brand name GHRP in Japan. It is used as a diagnostic agent in a single-dose formulation for the assessment of growth hormone deficiency (GHD). Pralmorelin (GHRP-2) acts to endogenously increase growth hormone release from the pituitary. With the increase of serum growth hormone, downstream effects occur. A notable hormone that is commonly used as a surrogate for growth hormone therapy, insulin like growth factor 1 (IGF-1), is known to increase with the infusion of GHRP-2. Administration of GHRP-2 results in amplification of the naturally occurring growth hormone secretion peaks, regulated by the hypothalamus and pituitary. After the release of growth hormone, a cascade of signaling events occurs in many body tissues, continuous exposure to growth hormone elicits long-term physiological changes. Of particular interest, especially in the case of the use of GHRP-2 as an alternative growth hormone therapy, hepatic production of IGF-1 occurs as result of endogenously released growth hormone from GHRP-2. GHRP-2 acts on the growth hormone secretagogue receptor (GHSR1a) in pituitary and hypothalamic tissues. The growth hormone secretagogue receptor (GHSR) is the natural receptor for the endogenous hormone Ghrelin, a stress hormone produced mainly by the lining of the stomach. This receptor among many other functions, controls and growth hormone release.

Vapreotide (Sanvar) is cyclic octapeptide analog of somatostatin with higher metabolic stability than the parent hormone and developed by Debiopharm Group for the treatment of esophageal variceal bleeding in patients with cirrhotic liver disease and AIDS-related diarrhea. Somatostatin inhibits the secretion of vasodilatory peptides from the gastrointestinal tract, including glucagon, which has been shown to contribute to the maintenance of portal hypertension. While natural somatostatin has a very short half-life (3 min), the elimination half-life of vapreotide is reported to be approximately 10 times longer than that of its parent compound. Pharmacodynamic studies of healthy volunteers demonstrated suppression of gastric acid secretion and inhibition of the secretion of pancreatic enzyme, which is similar to somatostatin. Vapreotide has demonstrated efficacy in the early management of acute variceal hemorrhage but only based on combined primary endpoints of hemostasis and survival after 5 days. In addition, vapreotide’s efficacy is limited to only one major study performed in Europe and not yet in the United States. Although it did not show a significant reduction in mortality, vapreotide’s observed the effect on hemostasis, as well as its favorable safety profile. Adverse effects that occurred in the vapreotide trials were generally mild and primarily included gastrointestinal symptoms and alterations of the gastrointestinal hormonal system. Vapreotide not recommended for approval by an FDA Advisory Panel due to Insufficient evidence that the drug provided a benefit in the treatment for acute esophageal variceal bleeding.
