Semaglutide, sold under the brand names Ozempic among others, is a medication used to treat type 2 diabetes and obesity.[1] It is less preferred to metformin, though they may be used together.[1][2] It improves blood sugar control, decreases the risk of heart disease, and decreases the risk of kidney problems.[1] It is used by mouth or by injection under the skin.[1]
Common side effects including nausea, vomiting, diarrhea, abdominal pain, and constipation.[1] Serious side effects may include diabetic ketoacidosis, low blood sugar, and pancreatitis.[2] There are concerns that use during pregnancy may harm the baby and use when breastfeeding is not recommended.[1] It works like human glucagon-like peptide-1 (GLP-1) and increases insulin release, decreases glucagon release, and slows stomach emptying.[2]
Semaglutide was approved for medical use in the United States in 2017.[1] It was developed by Novo Nordisk.[1] It was the first GLP-1 that can be taken by mouth.[6] In the United Kingdom 2 mg for injection costs the NHS about £73 as of 2020.[2] This amount in the United States costs about 850 USD as of 2021.[7]
Medical uses
Semaglutide is used to treat type 2 diabetes.[1]
For obesity it results in about 7 to 13% more weight loss (6 to 12 kg) than a placebo.[8] Though weight is regained if stopped.[8]
Dosage
By mouth, the typical initial dose is 3 mg once per day for the first month.[1] This may than be increased to 7 mg daily and 14 mg daily.[1] Once people are at 14 mg by mouth once a day they may be switched to 0.25 mg once per week for 4 weeks, which is than increased to 0.5 and potentially 1 mg per week.[1] It may also be started as 0.25 mg SC once per week.[2]
For obesity it is used at a dose of 2.4 mg once per week by injection.[8]
It is prepared for subcutaneous injection and is available in prefilled pen. It is recommended for once-weekly injection.[9]
Side effects
Side effects including nausea, vomiting, diarrhea, abdominal pain, and constipation may occur. In people with heart problems, it can cause damage to the back of the eye (retinopathy).[10] Side effects include medullary thyroid cancer, kidney problems, diabetic retinopathy, allergic reactions, low blood sugar, and pancreatitis.[6]
Mechanism of action
Semaglutide is a glucagon-like peptide-1 receptor agonist. It increases the production of insulin, a hormone that lowers the blood sugar level.[11] It also appears to enhance growth of β cells in the pancreas, which are the sites of insulin production.[12] On the other hand it inhibits glucagon, which is a hormone that increases blood sugar. It additionally reduces food intake by lowering appetite and slows down digestion in the stomach.[10] In this way it works in body fat reduction.[9]
Structure
Semaglutide is chemically similar to human glucagon-like peptide-1 (GLP-1), with 94% similarity. The only differences are two amino acid substitutions at positions 8 and 34, where alanine and lysine are replaced by 2-aminoisobutyric acid and arginine respectively.[13] Amino acid substitution at position 8 prevents chemical breakdown by an enzyme dipeptidyl peptidase-4. In addition, lysine at position 26 is in its derivative form (acylated with stearic diacid). Acylation with a spacer and C-18 fatty diacid chain increases the drug binding to blood protein (albumin), which enables longer presence in the blood circulation.[14] Its half-life in the blood is about 7 days (165–184 hours), therefore, once-weekly injection is enough.[12]
History
Semaglutide was developed in 2012,[15] by a team of researchers at Novo Nordisk as a longer-acting alternative to liraglutide.[16] It was given the brand name Ozempic. Clinical trials were started in 2015, and phase III was completed in 2016.[17]
Researchers at the University of Leeds and Novo Nordisk reported in 2017, that it can also be used for the treatment of obesity.[18] It reduces hunger, food craving and body fat.[19] A Phase 3 Randomized Controlled Trial found that once-weekly injection of 2.4 mg of the drug resulted in an average change of −14.9% body weight at 68 weeks compared to −2.4% for the placebo.[20]
The US FDA New Drug Application (NDA) was filed in December 2016, and in October 2017, the FDA Advisory Committee voted 16–0 in favor.[21] Approval was announced in December 2017 for the injectable version.[22] It can be used as both injection-type or oral-type drug.[23] The marketing authorization in the European Union was granted in February 2018.[4][24] The Japanese Ministry of Health, Labour and Welfare announced approval on 23 March 2018.[25] Health Canada issued approval on 4 January 2018.[26] Semaglutide was approved for medical use in Australia in August 2019.[27]
A version which is taken by mouth (Rybelsus) was approved for medical use in the United States in September 2019,[28] and in the European Union in April 2020.[5]
