Sebuah tinjauan besar terhadap uji coba hasil kardiovaskular menemukan bahwa orang yang mengonsumsi agonis reseptor GLP-1—obat yang mencakup semaglutide (dijual sebagai Ozempic)—memiliki risiko lebih rendah terhadap kejadian besar terkait jantung dibandingkan mereka yang diberi plasebo. Analisis tersebut menggabungkan hasil dari 11 uji coba yang melibatkan lebih dari 90.000 peserta, dengan rata-rata masa tindak lanjut hampir tiga tahun, serta melaporkan manfaat di seluruh subkelompok pasien termasuk mereka yang menderita diabetes maupun tidak.

Para peneliti di Anglia Ruskin University menganalisis 11 uji coba hasil kardiovaskular besar terhadap agonis reseptor glucagon-like peptide-1 (GLP-1) yang memantau peserta setidaknya selama satu tahun.

Dalam gabungan kumpulan data—yang mencakup lebih dari 90.000 peserta dengan rata-rata masa tindak lanjut hampir tiga tahun—pengobatan dengan agonis reseptor GLP-1 dikaitkan dengan sekitar 13% penurunan risiko kejadian kardiovaskular buruk yang besar (komposit yang mencakup serangan jantung, stroke, dan kematian kardiovaskular) dibandingkan dengan plasebo.

Tinjauan tersebut juga melaporkan tingkat kematian akibat semua penyebab yang lebih rendah, serta penurunan pada serangan jantung non-fatal, stroke non-fatal, dan rawat inap akibat gagal jantung di antara orang-orang yang diberikan obat GLP-1. Manfaat terkuat terlihat pada kelompok yang sudah dianggap berisiko tinggi terkena penyakit kardiovaskular, seperti orang dengan obesitas, diabetes tipe 2, atau penyakit jantung yang sudah ada.

Apa yang dikatakan orang

Reaksi awal di X menyoroti manfaat kardiovaskular dari obat GLP-1 seperti semaglutide dari tinjauan besar uji coba, dengan mencatat penurunan 20% dalam serangan jantung, stroke, dan kematian. Pengguna menekankan manfaat yang terlepas dari penurunan berat badan dan implikasi yang lebih luas untuk pencegahan penyakit jantung. Para profesional medis mendiskusikan data uji coba dan rekomendasi, dengan beberapa mencatat profil keamanan dan penerapan di dunia nyata.

Study finds people who use Ozempic-like drugs for weight loss face added stigma

People who lose weight using GLP-1 medications such as Ozempic and Wegovy may be judged more negatively than those who lose weight through diet and exercise — and even more negatively than people who do not lose weight at all — according to a new study led by Rice University psychologist Erin Standen.

A large study tracking nearly 100,000 people in Sweden found that GLP-1 receptor agonists like semaglutide, sold as Ozempic and Wegovy, are associated with significantly fewer psychiatric hospital visits and reduced sick days due to mental health issues. Researchers observed drops of up to 47% in various mental health risks during drug use periods. The findings appear in The Lancet Psychiatry.

A year-long observational study in Japan suggests that people with type 2 diabetes who tend to overeat in response to tempting food cues such as sight and smell may see greater weight loss—and possibly better blood-sugar improvement—after starting GLP-1 receptor agonists, while those with primarily emotional eating patterns show less consistent links to long-term outcomes.

Researchers at Vanderbilt Health discovered that both popular weight loss drugs and bariatric surgery significantly reduce fat mass while causing modest losses in fat-free mass, including muscle, in patients with obesity. The findings, based on over 3,000 patients, show improvements in overall body composition over 24 months. Maintaining this balance is crucial for long-term health, the study emphasizes.

University of Utah scientists report that a radical SAM enzyme known as PapB can join the ends of certain therapeutic peptides to form stable, ring-shaped structures. In experiments described in ACS Bio & Med Chem Au, the enzyme macrocyclized GLP-1-like peptides—including versions containing nonstandard amino acids found in some modern incretin drugs—an approach the researchers say could help make GLP-1 medicines such as semaglutide (Ozempic and Wegovy) more resistant to breakdown.

Researchers in Barcelona report that the lipid drug pemafibrate and the blood-pressure medicine telmisartan reduced diet-induced liver fat in rats and in a zebrafish model of fatty liver disease, with a half-dose combination performing as well as full doses of either drug alone. The work, published in Pharmacological Research, also describes a role for the PCK1 protein in telmisartan’s liver effects and argues that clinical trials would be needed to confirm any benefit in people.

University of Oklahoma scientists report that the hormone FGF21 reduces body weight in obese mice by acting on a hindbrain pathway—centered on the nucleus of the solitary tract and area postrema—that relays signals to the parabrachial nucleus. The team says the mechanism overlaps anatomically with brain regions implicated in GLP-1 drugs, but appears to promote weight loss mainly by increasing metabolic rate rather than primarily suppressing food intake.
