Benzoyl peroxide
|
DB09096 |
[Benzoyl peroxide (BPO) is an organic compound in the peroxide family. It is formed by two benzoyl groups which are connected by a peroxide link. It is one of the most important organic peroxides in terms of applications. In medicine, benzoyl peroxide is used as a topical treatment for acne, either in combination with antibiotics or as a single agent. These products are available over-the-counter or by prescription in gels, creams or liquids at concentrations of 2.5%, 5% or 10%. Benzoyl peroxide is also used for bleaching flour or hair, teeth whitening, for cross-linking polyester resins, and many other chemical uses. It is on the World Health Organization's List of Essential Medicines, the most important medications needed in a basic health system.] |

Somatostatin
|
DB09099 |
[Somatostatin, also known as growth hormone-inhibiting hormone, is a naturally-occurring peptide hormone of 14 or 28 amino acid residues [T28] that regulates the endocrine system. It is secreted by the D cells of the islets to inhibit the release of insulin and glucagon, and is also generated in the hypothalamus, where it inhibits the release of growth hormone and thyroid-stimulating hormones from the anterior pituitary [T28]. Somatostatin is initially secreted as a 116 amino acid precursor, preprosomatostatin, which undergoes endoproteolytic cleavage to prosomastatin. Prosomastatin is further process into two active forms, somatostatin-14 (SST-14) and somatostatin-28 (SST-28), an extended SST-14 sequence to the N-terminus [A20384]. The actions of somatostatin are mediated via signalling pathways of G protein-coupled somatostatin receptors.
Antineoplastic effects and potential uses of somatostatin on various tumours, including pituitary adenomas, GEP-NETs, paragangliomas, carcinoids, breast cancers, malignant lymphoma and small-cell lung cancers, have been extensively investigated [A20384]. Somatostatin has been used in the clinical setting for the diagnosis of acromegaly and gastrointestinal tract tumours. Its analogues have been developed to achieve more favourable kinetics for efficiency use in the management of acute conditions, such as esophageal varices. [DB00104] is a long-acting analogue of somatostatin that inhibits the release of a number of hormones, and is clinically used to relieve symptoms of uncommon gastroenteropancreatic endocrine tumours, as well as treat acromegaly [T28].] |

Somatrem
|
DB09098 |
[In 1985 somatrem (methionyl-growth hormone) became the first recombinant growth hormone product to be marketed commercially (Protropin by Genentech) [L1909]. The agent has the same amino acid sequence as human growth hormone except for an extra methionine at the end of the sequence chain to facilitate its manufacturing process [L1909].
Although the first commercially marketed recombinant growth hormone product Protropin was discontinued in 2004 owing to a relative explosion in brand and generic based releases of competing companies' own recombinant growth hormone products and the ensuing competition in product price over the years, many companies now produce and sell various approved formulations of methionyl-growth hormone, including Genetech's own current Nutropin product [L1909].
Despite the ability of almost all contemporary recombinant growth hormones to cause definite and demonstrable increases in growth rate in patients who are administered the drug, the use of these agents continues to be mired in persistent bioethical debate [A32292]. Such discussion revolves around whether patients' natural disposition of short stature should be considered a medical condition justifying medical treatment with such hormone therapy - especially when these hormone agents have been proven effective at increasing the height of children with or without growth hormone deficiency [A32292].] |

Chlorobutanol
|
DB11386 |
[Chlorobutanol, or chlorbutol, is an alcohol-based preservative with no surfactant activity [A32746]. It also elicits sedative-hypnotic and weak local anesthetic actions in addition to antibacterial and antifungal properties. Similar in nature to chloral hydrate, it is formed by the simple nucleophilic addition of chloroform and acetone.
As a long-term stabilizer of multi-ingredient preparations, chlorobutanol is normally used at a concentration of 0.5%. At this concentration, it also conserves its antimicrobial activity.
Due to the long terminal half-life of 37 days, the use of chlorobutanol as a sedative is limited because of the considerable accumulation which will occur following multiple dosing [A32743]. Chlorobutanol is a common detergent preservative in eye drops and other ophthalmic therapeutic formulations [A32744].] |

Cannabidiol
|
DB09061 |
[Cannabidiol, or CBD, is one of at least 85 active cannabinoids identified within the Cannabis plant. It is a major phytocannabinoid, accounting for up to 40% of the Cannabis plant's extract, that binds to a wide variety of physiological targets of the endocannabinoid system within the body. Although the exact medical implications are currently being investigated, CBD has shown promise as a therapeutic and pharmaceutical drug target. In particular, CBD has shown promise as an analgesic, anticonvulsant, muscle relaxant, anxiolytic, antipsychotic and has shown neuroprotective, anti-inflammatory, and antioxidant activity, among other currently investigated uses [A32477, A32469]. CBD's exact place within medical practice is still currently hotly debated, however as the body of evidence grows and legislation changes to reflect its wide-spread use, public and medical opinion have changed significantly with regards to its usefulness in a number of medical conditions ranging from anxiety to epilepsy.
From a pharmacological perspective, Cannabis' (and CBD's) diverse receptor profile explains its potential application for such a wide variety of medical conditions. Cannabis contains more than 400 different chemical compounds, of which 61 are considered cannabinoids, a class of compounds that act upon endogenous cannabinoid receptors of the body [A32584]. Cannabinoid receptors are utilized endogenously by the body through the endocannabinoid system, which includes a group of lipid proteins, enzymes, and receptors that are involved in many physiological processes. Through its modulation of neurotransmitter release, the endocannabinoid system regulates cognition, pain sensation, appetite, memory, sleep, immune function, and mood among many other bodily systems. These effects are largely mediated through two members of the G-protein coupled receptor family, cannabinoid receptors 1 and 2 (CB1 and CB2)[A32585,A32824]. CB1 receptors are found in both the central and peripheral nervous systems, with the majority of receptors localized to the hippocampus and amygdala of the brain. Physiological effects of using cannabis make sense in the context of its receptor activity as the hippocampus and amygdala are primarily involved with regulation of memory, fear, and emotion. In contrast, CB2 receptors are mainly found peripherally in immune cells, lymphoid tissue, and peripheral nerve terminals [A32676].
Tetrahydrocannabinol (THC) and cannabidiol (CBD) are two types of cannabinoids found naturally in the resin of the marijuana plant, both of which interact with the cannabinoid receptors that are found throughout the body. Although THC and CBD have been the most studied cannabinoids, there are many others identified to date including cannabinol (CBN), cannabigerol (CBG), [DB14050] (CBDV), and [DB11755] (THCV) that can be found within the medical cannabis [A32830]. While both CBD and THC are used for medicinal purposes, they have different receptor activity, function, and physiological effects. If not provided in their activated form (such as through synthetic forms of THC like [DB00470] or [DB00486]), THC and CBD are obtained through conversion from their precursors, tetrahydrocannabinolic acid-A (THCA-A) and cannabidiolic acid (CBDA), through decarboxylation reactions. This can be achieved through heating, smoking, vaporization, or baking of dried unfertilized female cannabis flowers.
The primary psychoactive component of Cannabis, delta 9-tetrahydrocannabinol (Δ9-THC), demonstrates its effects through weak partial agonist activity at Cannabinoid-1 (CB1R) and Cannabinoid-2 (CB2R) receptors. This activity results in the well-known effects of smoking cannabis such as increased appetite, reduced pain, and changes in emotional and cognitive processes. In contrast to THC's weak agonist activity, CBD has been shown to act as a negative allosteric modulator of the cannabinoid CB1 receptor, the most abundant G-Protein Coupled Receptor (GPCR) in the body [A32469]. Allosteric regulation is achieved through the modulation of receptor activity on a functionally distinct site from the agonist or antagonist binding site which is clinically significant as direct agonists (such as THC) are limited by their psychomimetic effects such as changes to mood, memory, and anxiety[A32469].
In addition to the well-known activity on CB1 and CB2 receptors, there is further evidence that CBD also activates 5-HT1A/2A/3A serotonergic and TRPV1–2 vanilloid receptors, antagonizes alpha-1 adrenergic and µ-opioid receptors, inhibits synaptosomal uptake of noradrenaline, dopamine, serotonin and gamma-aminobutyric acid (GABA), and cellular uptake of anandamide, acts on mitochondria Ca2+ stores, blocks low-voltage-activated (T-type) Ca2+ channels, stimulates activity of the inhibitory glycine-receptor, and inhibits activity of fatty amide hydrolase (FAAH) [A31555, A31574].
CBD is currently available in Canada within a 1:1 formulation with tetrahydrocannbinol (THC) (as the formulation known as "nabiximols") as the brand name product Sativex. It is approved for use as adjunctive treatment for symptomatic relief of spasticity in adult patients with multiple sclerosis (MS). Sativex was also given a conditional Notice of Compliance (NOC/c) for use as adjunctive treatment for the symptomatic relief of neuropathic pain in adult patients with multiple sclerosis and as adjunctive analgesic treatment for moderate to severe pain in adult patients with advanced cancer [L886].
In April 2018, a Food and Drug Administration advisory panel unanimously recommended approval of Epidiolex (cannabidiol oral solution) for the treatment of two rare forms of epilepsy - Lennox-Gastaut syndrome and Dravet syndrome, which are among the two most difficult types of epilepsy to treat [L2721, L2719]. Epidiolex was granted Orphan Drug designation as well as Fast Track Approval from the FDA for further study in these hard to treat conditions. Notably, phase 3 clinical trials of Epidiolex have demonstrated clinically significant improvement in Lennox-Gastaut syndrome and Dravet syndrome [L2720]. On June 25th, 2018, Epidiolex was approved by the FDA to be the first CBD-based product available on the US market.] |

Ceritinib
|
DB09063 |
[Ceritinib is used for the treatment of adults with anaplastic lymphoma kinase (ALK)-positive metastatic non-small cell lung cancer (NSCLC) following failure (secondary to resistance or intolerance) of prior crizotinib therapy. About 4% of patients with NSCLC have a chromosomal rearrangement that generates a fusion gene between EML4 (echinoderm microtubule-associated protein-like 4) and ALK (anaplastic lymphoma kinase), which results in constitutive kinase activity that contributes to carcinogenesis and seems to drive the malignant phenotype. Ceritinib exerts its therapeutic effect by inhibiting autophosphorylation of ALK, ALK-mediated phosphorylation of the downstream signaling protein STAT3, and proliferation of ALK-dependent cancer cells. Following treatment with crizotinib (a first-generation ALK inhibitor), most tumours develop drug resistance due to mutations in key "gatekeeper" residues of the enzyme. This occurrence led to development of novel second-generation ALK inhibitors such as ceritinib to overcome crizotinib resistance. The FDA approved ceritinib in April 2014 due to a surprisingly high response rate (56%) towards crizotinib-resistant tumours and has designated it with orphan drug status.] |

Corifollitropin alfa
|
DB09066 |
[Corifollitropin alfa, also known as _Elonva_ is used in women undergoing fertility treatment to stimulate the development of more than one mature egg (oocyte) at a time in the ovaries. This drug used together with _a gonadotropin-releasing hormone (GnRH) antagonist_, a type of medicine also used in fertility treatments. Elonva is available only by prescription [L2270].
In July 2014, Merck announced the receipt of a Complete Response Letter (CRL) from the U.S. FDA for its New Drug Application for this drug. Corifollitropin alfa is marketed as Elonva in more than 75 countries [L2272].
Corifollitropin alfa is produced by a method known as ‘recombinant DNA technology’. This means that it is made by cells into which a DNA has been introduced that makes them able to produce corifollitropin alfa [L2270].
Multiple studies and a meta-analysis suggest that corifollitropin alfa is as efficacious as recombinant FSH in terms of live birth rate, ongoing pregnancy rate, as well as clinical pregnancy rate. The increased in the number of eggs retrieved under corifollitropin alfa regimen represents the elevated effectiveness of this drug, however, warns at the same time against the possibility of an increased risk of ovarian hyperstimulation in the high responder study group of women [L2276], [A32526].] |

Cobicistat
|
DB09065 |
[Cobicistat, marketed under the name Tybost (formerly GS-9350), indicated for treating infection with human immunodeficiency virus (HIV). Although it does not have any anti-HIV activity, cobicistat acts as a pharmacokinetic enhancer by inhibiting cytochrome P450 3A isoforms (CYP3A) and therefore increases the systemic exposure of coadministered agents that are metabolized by CYP3A enzymes. More specifically, cobicistat is indicated to increase systemic exposure of atazanavir or darunavir (once daily dosing regimen) in combination with other antiretroviral agents in the treatment of HIV-1 infection. Increasing systemic exposure of anti-retrovirals (ARVs) without increasing dosage allows for better treatment outcomes and a decreased side effect profile.] |

Vortioxetine
|
DB09068 |
[Vortioxetine is an atypical antipsychotic and antidepressant indicated for the treatment of major depressive disorder (MDD). It is classified as a serotonin modulator and simulator (SMS) as it has a multimodal mechanism of action towards the serotonin neurotransmitter system whereby it simultaneously modulates one or more serotonin receptors and inhibits the reuptake of serotonin. More specifically, vortioxetine acts via the following biological mechanisms: as a serotonin reuptake inhibitor (SRI) through inhibition of the serotonin transporter, as a partial agonist of the 5-HT1B receptor, an agonist of 5-HT1A, and an antagonist of the 5-HT3, 5-HT1D, and 5-HT7 receptors. SMSs were developed because there are many different subtypes of serotonin receptors, however, not all of these receptors appear to be involved in the antidepressant effects of SRIs. Some serotonin receptors seem to play a relatively neutral or insignificant role in the regulation of mood, but others, such as 5-HT1A autoreceptors and 5-HT7 receptors, appear to play an oppositional role in the efficacy of SRIs in treating depression.] |

Corticorelin ovine triflutate
|
DB09067 |
[Corticorelin, available commercially as corticorelin ovine triflutate (tradename Acthrel), is a synthetic form of the peptide human corticotropin-releasing hormone (hCRH), a potent stimulator of adrenocorticotropic hormone (ACTH) release from the anterior pituitary. Endogenous forms hCRH are involved in the stress response and its main function is stimulation of the pituitary to release ACTH.
It is used as a diagnostic agent to evaluate the status of the pituitary-adrenal axis in the differentiation of a pituitary source from an ectopic source of excessive ACTH secretion. It provides a differential diagnosis for Cushing's disease (a pituitary source of ACTH excess) or of ectopic ACTH syndrome (an ectopic source of ACTH excess). If corticorelin injection results in an increase of plasma ACTH and cortisol, the patient is diagnosed with Cushing's disease. However, if corticorelin injection does not result in an increase of plasma ACTH and cortisol, the patient is diagnosed with ectopic ACTH syndrome.] |

Trimetazidine
|
DB09069 |
[Trimetazidine is a drug for angina pectoris sold under the brand name Vastarel MR. Trimetazidine is described as the first cytoprotective anti-ischemic agent developed and marketed by Laboratoires Servier (France). Trimetazidine is an anti-ischemic (anti-anginal) metabolic agent, which improves myocardial glucose utilization through inhibition of long-chain 3-ketoacyl CoA thiolase activity, which results in a reduction in fatty acid oxidation and a stimulation of glucose oxidation. High fatty acid oxidation rates are detrimental during ischemia due to an inhibition of glucose oxidation leading to uncoupling of glycolysis and an increase in proton production, which has the potential to accelerate sodium and calcium overload in the heart, which leads to an exacerbation of ischemic injury and decreased cardiac efficiency during reperfusion.] |
