Eltrombopag is a thrombopoietin (TPO) nonpeptide mimetic administered orally that activates the TPO receptor by binding to the transmembrane domain and initiates signaling cascades that induce proliferation and differentiation of megakaryocytes from bone marrow progenitor cells. Eltrombopag under brand name promacta is approved for the treatment of the low blood platelet counts in adults with chronic immune (idiopathic) thrombocytopenia (ITP), when certain other medicines, or surgery to remove the spleen, have not worked well enough. ITP is a condition that may cause unusual bruising or bleeding due to an abnormally low number of platelets in the blood. Eltrombopag has also been approved for the treatment of thrombocytopenia (low blood platelet counts) in patients with chronic hepatitis C to allow them to initiate and maintain interferon-based therapy and to treat patients with severe aplastic anemia who have had an insufficient response to immunosuppressive therapy.

DEGARELIX (FIRMAGON®) is a synthetic linear decapeptide amide containing seven unnatural amino acids, five of which are D-amino acids. It is a GnRH receptor antagonist. It binds reversibly to the pituitary GnRH receptors, thereby reducing the release of gonadotropins and consequently testosterone. DEGARELIX (FIRMAGON®) is effective in achieving and maintaining testosterone suppression below the castration level of 50 ng/dL and is indicated for the treatment of patients with advanced prostate cancer.

Icosapent is an important polyunsaturated fatty acid found in fish oils. It serves as the precursor for the prostaglandin-3 and thromboxane-3 families. A diet rich in eicosapentaenoic acid lowers serum lipid concentration, reduces incidence of cardiovascular disorders, prevents platelet aggregation, and inhibits arachidonic acid conversion into the thromboxane-2 and prostaglandin-2 families. EPA can be used for lowering elevated triglycerides in those who are hyperglyceridemic. In addition, EPA may play a therapeutic role in patients with cystic fibrosis by reducing disease severity and may play a similar role in type 2 diabetics in slowing the progression of diabetic nephropathy.

Tetrabenazine (trade name Xenazine) is a monoamine depleter and used as the symptomatic treatment of chorea associated with Huntington's disease. Tetrabenazine is a reversible human vesicular monoamine transporter type 2 inhibitor (Ki = 100 nM). It acts within the basal ganglia and promotes depletion of monoamine neurotransmitters serotonin, norepinephrine, and dopamine from stores. It also decreases uptake into synaptic vesicles. Dopamine is required for fine motor movement, so the inhibition of its transmission is efficacious for hyperkinetic movement. Tetrabenazine exhibits weak in vitro binding affinity at the dopamine D2 receptor. The most common adverse reactions, which have occurred in at least 10% of subjects in studies and at least 5% greater than in subjects who received placebo, have been: sedation or somnolence, fatigue, insomnia, depression, suicidal thoughts, akathisia, anxiety, and nausea.

Methylnaltrexone, is a peripherally acting μ-opioid receptor antagonist that acts on the gastrointestinal tract to inhibit the opioid-induced decrease in gastric motility and transit time. It is used to treat opiate-induced constipation in adults with chronic non-cancer pain and in adults with advanced illness who are receiving palliative care.

Dapagliflozin (trade name Farxiga in the U.S. and Forxiga in the EU and Russia) is a drug of the gliflozin class, developed by Bristol-Myers Squibb in partnership with AstraZeneca. Farxiga is a sodium-glucose cotransporter 2 (SGLT2) inhibitor indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

Fesoterodine (trade name Toviaz) is a prodrug of 5-hydroxymethyl tolterodine, which is also the active metabolite of tolterodine. Fesoterodine and its active metabolites are nonsubtype selective, competitive antagonists of human muscarinic receptors, but 5-hydroxymethyl tolterodine has greater potency than the parent compound. A prodrug approach was necessary for systemic bioavailability of 5-hydroxymethyl tolterodine after oral administration. Fesoterodine was originated by Schwarz Pharma (later a subsidiary of UCB) and is being developed by Pfizer for the treatment of overactive bladder and urinary urge incontinence. The agent is launched in several countries for the treatment of overactive bladder, including the US, Japan, Canada, Europe and Asia.

Tapentadol is the first US FDA-approved centrally acting analgesic having both μ-opioid receptor agonist and noradrenaline (norepinephrine) reuptake inhibition activity with minimal serotonin reuptake inhibition. Tapentadol is indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate, neuropathic pain associated with diabetic peripheral neuropathy (DPN) severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate.

Alvimopan (LY246736, ADL 8-2698, trade name Entereg) is a potent, peripherally selective mu-opioid receptor antagonist. Alvimopan was developed by Adolor Corporation (now Cubist Pharmaceuticals) and GlaxoSmithKline for the treatment of postoperative ileus. Postoperative ileus is the impairment of gastrointestinal motility after intra-abdominal surgery or other non-abdominal surgeries. This may potentially delay gastrointestinal recovery and hospital discharge until its resolution. Morphine and other mu-opioid receptor agonists are universally used for the treatment of acute postsurgical pain; however, they are known to have an inhibitory effect on gastrointestinal motility and may prolong the duration of postoperative ileus. Following oral administration, alvimopan antagonizes the peripheral effects of opioids on gastrointestinal motility and secretion by competitively binding to gastrointestinal tract mu-opioid receptors.
