MOVANTIK (naloxegol) is a peripherally-acting mu-opioid receptor antagonist indicated for the treatment of opioid-induced constipation (OIC) in adult patients with chronic noncancer pain. It is being investigated for the treatment of constipation as a side effect of prescription opioid pain medicines.

Empagliflozin is a selective sodium glucose cotransporter-2 (SGLT-2) inhibitor designed for the treatment of type 2 diabetes mellitus. By inhibiting SGLT2, empagliflozin reduces renal reabsorption of filtered glucose and lowers the renal threshold for glucose, and thereby increases urinary glucose excretion. Empagliflozin interacts with diuretics, blood presure medicine and insulin. Jardiance reduces the risk of cardiovascular death in diabetes patients at high cardiovascular risk.

Eliglustat, marketed by Genzyme as CERDELGA, is a glucosylceramide synthase inhibitor indicated for the long-term treatment of type 1 Gaucher disease who are CYP2D6 extensive metabolizers, intermediate metabolizers, or poor metabolizers (PMs) as detected by an FDA-cleared test.

Alogliptin (trade name Nesina in the US and Vipidia in Europe) is an orally administered anti-diabetic drug in the DPP-4 inhibitor class, discovered by Takeda Pharmaceutical Company's wholly owned subsidiary, Takeda San Diego, Inc. (former Syrrx) which was acquired by Takeda in 2005. Alogliptin does not decrease the risk of heart attack and stroke. Like other members of the gliptin class, it causes little or no weight gain, exhibits relatively little risk of causing hypoglycemia, and exhibits relatively modest glucose-lowering activity. Alogliptin and other gliptins are commonly used in combination with metformin in patients whose diabetes cannot adequately be controlled with metformin alone.

Canagliflozin (INN, trade name Invokana or Sulisent) is a drug of the gliflozin class. It was developed by Mitsubishi Tanabe Pharma and is marketed under license by Janssen, a division of Johnson & Johnson. Canagliflozin is an antidiabetic drug used to improve glycemic control in people with type 2 diabetes. Sodium-glucose co-transporter 2 (SGLT2), expressed in the proximal renal tubules, is responsible for the majority of the reabsorption of filtered glucose from the tubular lumen. Canagliflozin is an inhibitor of SGLT2. By inhibiting SGLT2, canagliflozin reduces reabsorption of filtered glucose and lowers the renal threshold for glucose (RTG), and thereby increases urinary glucose excretion. In extensive clinical trials, canagliflozin produced a consistent dose-dependent reduction in HbA1c of 0.77% to 1.16% when administered as monotherapy, combination with metformin, combination with metformin and a sulfonylurea, combination with metformin and pioglitazone, and in combination with insulin from a baselines of 7.8% to 8.1%, in combination with metformin, or in combination with metformin and a sulfonylurea. When added to metformin, canagliflozin 100 mg was shown to be non-inferior to both sitagliptin 100 mg and glimepiride in reductions on HbA1c at one year, whilst canagliflozin 300 mg successfully demonstrated statistical superiority over both sitagliptin and glimiperide in HbA1c reductions. Secondary efficacy endpoint of superior body weight reduction and blood pressure reduction (versus sitagliptin and glimiperide)) were observed as well. Canagliflozin produces beneficial effects on HDL cholesterol whilst increasing LDL cholesterol to produce no change in total cholesterol.

Fidaxomicin (trade names Dificid, Dificlir in Europe) is the first in a new class of narrow spectrum macrocyclic antibiotic drugs indicated for treatment of Clostridium difficile-associated diarrhea. Lipiarmycin (fidaxomicin), a metabolite of Actinoplanes deccanensis nov. sp. was first isolated in pure form in 1970s and was considered as antibiotic from its chemical and physico-chemical characteristics. It demonstrated high activity against Gram-positive bacteria, including strains resistant to the medically important antibiotics and protected mice experimentally infected with Streptococcus haemolyticus. Fidaxomicin is non-systemic, meaning it is minimally absorbed into the bloodstream, it is bactericidal, and it has demonstrated selective eradication of pathogenic Clostridium difficile with minimal disruption to the multiple species of bacteria that make up the normal, healthy intestinal flora. Although the exact mechanism of action has yet to be fully elucidated, fidaxomicin may bind to and inhibit bacterial DNA-dependent RNA polymerase, thereby inhibiting the initiation of bacterial RNA synthesis. When orally administered, this agent is minimally absorbed into the systemic circulation, acting locally in the gastrointestinal tract. Fidaxomicin appears to be active against pathogenic Gram-positive bacteria, such as clostridia, enterococci, and staphylococci, but does not appear to be active against other beneficial intestinal bacteria. The maintenance of normal physiological conditions in the colon can reduce the probability of Clostridium difficile infection recurrence. It is marketed by Cubist Pharmaceuticals after acquisition of its originating company Optimer Pharmaceuticals.

Linagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor discovered by Boehringer Ingelheim and being developed as an oral once-daily tablet for the treatment of Type 2 diabetes. Linagliptin was first approved by FDA in 2011 under the trade name Tradjenta as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. Linagliptin binds to DPP-4 (an enzyme that degrades the incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP)) in a reversible manner and thus increases the concentrations of incretin hormones. Linagliptin glucose dependently increases insulin secretion and lowers glucagon secretion, thus resulting in better regulation of glucose homeostasis. Linagliptin binds selectively to DPP-4, and selectively inhibits DPP-4 but not DPP-8 or DPP-9 activity in vitro at concentrations approximating therapeutic exposures.

Carglumic acid is a Carbamoyl Phosphate Synthetase 1 (CPS 1) allosteric modulator. CPS1 is found in the mitochondria and is the first enzyme of the urea cycle, which converts ammonia into urea. Carglumic acid acts as a replacement for NAG in NAGS deficiency patients by activating CPS1 but it does not help to regulate the urea cycle. Carglumic acid under the trade name Carbaglu indicated as adjunctive therapy for the treatment of acute hyperammonemia due to the deficiency of the hepatic enzyme N-acetylglutamate synthase (NAGS). In addition, as maintenance therapy for the treatment of chronic hyperammonemia due to the deficiency of the hepatic enzyme N-acetylglutamate synthase (NAGS). This rare genetic disorder results in elevated blood levels of ammonia, which can eventually cross the blood–brain barrier and cause neurologic problems, cerebral edema, coma, and death.

Saxagliptin is an orally active hypoglycemic (anti-diabetic drug) of the new dipeptidyl peptidase-4 (DPP-4) inhibitor class of drugs. FDA approved on July 31, 2009. Saxagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor antidiabetic for the treatment of type 2 diabetes. DPP-4 inhibitors are a class of compounds that work by affecting the action of natural hormones in the body called incretins. Incretins decrease blood sugar by increasing consumption of sugar by the body, mainly through increasing insulin production in the pancreas, and by reducing production of sugar by the liver. [Bristol-Myers Squibb Press Release] DPP-4 is a membrane associated peptidase which is found in many tissues, lymphocytes and plasma. DPP-4 has two main mechanisms of action, an enzymatic function and another mechanism where DPP-4 binds adenosine deaminase, which conveys intracellular signals via dimerization when activated. Saxagliptin forms a reversible, histidine-assisted covalent bond between its nitrile group and the S630 hydroxyl oxygen on DPP-4. The inhibition of DPP-4 increases levels active of glucagon like peptide 1 (GLP-1), which inhibits glucagon production from pancreatic alpha cells and increases production of insulin from pancreatic beta cells.

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.
