Linagliptin 2.5mg / Metformin 850mg tablets

Metformin is a cheap, orally administered, guideline recommended glucose-lowering drug (GLD), initiated as monotherapy in treatment naïve newly diagnosed type 2 diabetes (T2D), and in combination with other GLDs in T2D not controlled on metformin. The unique Asian T2D phenotype that is markedly different than Western population, and warrants T2D treatment approaches unique to the Asian population. However, the bulk of metformin literature is from Western population and may not be generalizable for Asians. The systematic review evaluated the efficacy and safety of metformin monotherapy and combination therapy in Asians. Literature on other GLDs recommended by the 2023 American Diabetes Association guidelines as add-on therapy to metformin were included from Asia. The systematic review concluded that metformin is effective and safe for long-term T2D control of T2D in Asians. Metformin monotherapy may be initiated and continued in treatment naïve Asian patients with T2D and/or obesity if the monotherapy is adequate for achieving glycemic control. Other GLDs may be added for better glycemic control for those who fail on monotherapy. Patients inadequately controlled on another first-line GLD can achieve glycemic control and target HbA1c of <7% by adding metformin in a once daily dose. The use of metformin reduces the risk of hypoglycemia, and its gastrointestinal side effects are mild and manageable in Asians.

This review evaluates the available pharmacokinetic data on the plasma-to-breastmilk transfer of first- and second-line T2DM drugs against available clinical guideline recommendations. A list of drug therapies for treating T2DM was generated from national and international clinical guidelines. A systematic search of research articles reporting human plasma and breastmilk drug concentrations was conducted in Scopus, PubMed, Google Scholar, and LactMed® in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies evaluating breastmilk drug transfer in T2DM, with fully accessible abstract and main text reported in English, were included. Study quality was evaluated using the ClinPK checklist. Authors evaluated clinical guideline recommendations on the use of T2DM drugs in lactation and the basis upon which such recommendations were made. Only 5 out of 20 drugs (metformin, glyburide, glipizide, tolbutamide, and semaglutide) have clinical data on plasma-to-breastmilk transfer. Metformin and tolbutamide were detectable in maternal plasma and breastmilk. Half (51.7%) of guideline recommendations provide explicit guidance. Only 4.4% of recommendations were based on clinical evidence. Over half (57.8%) of recommendations were accessible online, and most guideline recommendations (78%) were against the use of antiglycemic agents while breastfeeding. The scarce clinical evidence to guide T2DM drug therapy during breastfeeding available has several design and methodological limitations. Published recommendations remain largely inconsistent, thus perpetuating uncertainty in the use of T2DM drug therapies in lactation. Addressing knowledge gaps is critical in developing clinical consensus to optimize T2DM drug therapy among breastfeeding mothers.

BackgroundThe incidence of type 2 diabetes mellitus (T2DM) in children and adolescents is increasing, yet there is limited information on the available pharmacological interventions to combat T2DM and prevent associated comorbidities.AimTo assess the effectiveness of current pharmacological treatments in managing T2DM in children and adolescents. The protocol of the study was registered in PROSPERO (CRD42022382165).MethodsSearches were performed in PubMed, EMBASE, Scopus, and ClinicalTrials.gov for publications between 1990 to September 2024 without language restrictions. Randomized control trials (RCTs) of pharmacotherapy in children and adolescents with T2DM (aged via RStudio, 'meta' and 'netmeta'.ResultsA total of 12 studies having low to moderate risk of bias with 1658 participants, and follow-up duration 12-52 weeks were included. In our network meta-analysis, compared to control(s), the reduction of HbA1c was significantly larger for dulaglutide [mean difference (MD), 95% confidence interval: -1.20, -2.12 to -0.28], followed by dapagliflozin (-0.94, -1.44 to -0.44), liraglutide (-0.91, -1.37 to -0.45), empagliflozin (-0.87, -1.40 to -0.34), exenatide (-0.59, -1.07 to -0.11) and linagliptin (-0.45, -0.87 to -0.02) while other drugs had little or no effect. While liraglutide was associated with a change in body weight [MD -2.41 (-4.68, -0.14) kg], no other drug treatment was associated with significant changes in body weight, BMI, and lipids. Apart from level 1 hypoglycemia with liraglutide [risk difference (RD): 0.20, 0.04-0.37] and minor adverse events with dulaglutide (RD: 0.24, 0.08-0.40), no other treatment was associated with excess risk of hypoglycemia or minor or major adverse events.ConclusionPharmacotherapy of T2DM with dulaglutide, dapagliflozin, liraglutide, empagliflozin, exenatide, and linagliptin in children is associated with modest reduction of HbA1c. Larger RCTs with longer follow-up durations are needed to guide better therapeutic decision making.

IntroductionAchieving and sustaining target glycated haemoglobin (HbA1c) levels is fundamental in the management of type 2 diabetes (T2D). We here aimed to assess whether initial dual oral therapy outperforms monotherapy in reaching glycaemic targets in patients with treatment-naive or early-stage T2D.MethodsThis systematic review and meta-analysis were registered with PROSPERO (CRD420251111096). Parallel-group randomised controlled trials with a duration of at least 12 weeks were identified through searches of PubMed and the Cochrane Library spanning 2005 to 2025. Data at the trial arm level, including baseline and endpoint HbA1c values, were extracted for seven predefined comparisons and combined using a random-effects inverse-variance meta-analysis in R version 4.3.1 (meta package). The primary outcome was the proportion of treatment arms achieving an HbA1c level of ≤7.5% (58 mmol/mol). Secondary outcomes included the proportions achieving HbA1c levels of ≤7.0% (53 mmol/mol) and ≤6.5% (48 mmol/mol), as well as mean differences in HbA1c levels.ResultsA total of 20 trials, encompassing 37 treatment arms, were analysed. Dual combination therapy consistently demonstrated superior efficacy compared to monotherapy. The proportion of patients achieving HbA1c levels of ≤7.5% (58 mmol/mol) was 86% with initial dual therapy versus 82% with initial monotherapy (odds ratio [OR] 1.33, 95% confidence interval [CI] 1.20-1.47, p = 0.002). At the more stringent threshold of ≤7.0% (53 mmol/mol), the rates were 69% versus 64% (OR 1.27, p = 0.003), and at ≤6.5% (48 mmol/mol), 42% versus 39% (OR 1.18, p = 0.056). When comparing initial dual therapy to metformin monotherapy, the respective achievement rates were 86% versus 81% (OR 1.41, p = 0.001) for a target of ≤7.0% (53 mmol/mol). The combination of metformin with a sodium-glucose cotransporter 2 inhibitor (SGLT2-i) resulted in 88% reaching ≤7.5% (58 mmol/mol), compared to 81% with metformin alone (OR 1.55, p ≤ 0.001), a difference significant across all thresholds. Dual therapy containing SGLT-2i achieved 87% at ≤7.5% (58 mmol/mol), compared with 82% with all monotherapies (OR 1.43, p ≤ 0.001). SGLT-2i monotherapy itself led to 89% reaching the target, compared with 81% with metformin (OR 1.73, p ≤ 0.001). No significant difference in outcome was observed between dual and monotherapy involving SGLT2-is (OR 0.87, p = 0.480). The pooled final HbA1c values were 6.7% (50 mmol/mol) for dual therapy and 7.9% (63 mmol/mol) for monotherapy, corresponding to a mean difference of -0.45% (95% CI -0.60 to -0.25, p ≤ 0.001). Heterogeneity among studies was low to moderate (I2 25%-50%), and results remained consistent after excluding rosiglitazone arms.ConclusionsInitial dual therapy, particularly combining metformin with an SGLT2-i, results in superior achievement of HbA1c targets across various thresholds compared to monotherapy. SGLT2-i alone surpasses metformin alone in efficacy. Adding a second agent to SGLT2-i did not provide additional glucose-lowering benefit to SGLT2-i monotherapy. Early initiation of SGLT2-i monotherapy or combination therapy should be considered upon diagnosis of T2D.

BackgroundPrediabetes refers to the transitional stage from normal glucose metabolism to diabetes. The International Diabetes Federation guidelines reported that, as of 2024, approximately 1.12 billion people globally were in the prediabetes stage. Without intervention, individuals with prediabetes are highly likely to progress to type 2 diabetes mellitus. It can be seen that prediabetes is posing a threat to human health and life and leads to a significant global public health concern.MethodsPubMed, Embase, Cochrane Library, Web of Science, and ClinicalTrials.gov were searched before March 29, 2025. Eligible randomized controlled trials (RCTs) enrolled adults with prediabetes, compared the efficacy and safety of placebo and anti-prediabetic drugs (e.g., metformin, sodium-glucose cotransporter 2 inhibitors, glucagon-like peptide-1 receptor agonists, and thiazolidinedione) with a follow-up duration of at least 12 weeks. Bayesian network meta-analysis was employed in statistical analysis.ResultsFifty-five eligible RCTs involving 37 interventions with 16,610 participants were included in this study. Compared with placebo, most anti-prediabetic drugs significantly reduced levels of hemoglobin A1c (HbA1c) (mean difference (MD), - 0.94 ~ - 0.27%), fasting plasma glucose (FPG) (MD, - 26.42 ~ - 0.15 mg/dL), weight loss (WL) (MD, - 13.59 ~ - 5.99 kg) and body mass index (BMI) (MD, - 4.50 ~ - 0.08 kg/m2). Specifically, 2.4 mg of semaglutide SC demonstrated the most optimal efficacy in WL (MD - 13.59 kg; 95% confidence interval (CI) - 17.30 to - 9.91) and favorable efficacy in lowering HbA1c (MD - 0.39%; 95% CI - 0.55 to - 0.25); 15 mg of tirzepatide showed significant efficacy in lowering FPG (MD - 9.58 mg/dL; 95% CI - 12.00 to - 7.15), and potent efficacy in lowering BMI. Thirty milligrams of pioglitazone showed excellent efficacy in lowering lipid and FPG. Among the interventions, there was no significant difference in the incidence of adverse events (AEs), while 100 mg of sitagliptin demonstrated higher incidence of serious adverse events (SAEs).ConclusionsAmong all the included interventions, GLP-1RAs, GIP/GLP-1RAs, and TZDs demonstrated favorable anti-prediabetic efficacy and acceptable safety. 2.4 mg of semaglutide SC and 15 mg of tirzepatide were the best option among the included interventions considering favorable glucose and BMI control.Systematic review registrationPROSPERO CRD42025636991.

IntroductionDPP-4 inhibitors use has been reported to cause heart failure events in patients with type-2 diabetes. The FDA had also issued warnings concerning increased risk of heart failure events for alogliptin, saxagliptin and their combination with metformin.MethodsRandomized controlled trials (RCTs) involving adult patients with type-2 diabetes patients with or without history of cardio-vascular disorders were included in the review. Cohort studies, case-control studies and other non-RCTs, and studies involving paediatric patients were excluded. Data bases searched were PubMed/Medline, DOAJ, MDPI, Google Scholar and clinicaltrails.gov. The search was conducted in late January of 2026. Risk of bias was assessed using RoB-2 tool for RCTs. Individual study outcomes were tabulated and summary measure was synthesized by meta-analysis under random effect model; GRADE certainty of evidence was used; sub-group analysis based on individual DPP-4 inhibitors, follow-up duration and placebo or other controls was done; systematic review was done under PRISMA 2020 Guidelines.ResultsThe meta-analysis was done under random effect computation model for all 29 included studies. The analysis for total of pooled 67,873 patients showed statistically insignificant association between the use of DPP-4 inhibitors and heart failure with Risk Ratio (RR) = 1.06, 95% Confidence Interval (CI) 0.94-1.12. Sub-group analysis found significant association of saxagliptin use with increased heart failure risk.ConclusionResults should be interpreted with caution because of several limitations of the study.Trial registrationPROSPERO, CRD420261288081.

Type 2 diabetes mellitus (T2DM) is characterized by progressive β-cell dysfunction, insulin resistance, and glucotoxicity, some of which may remain reversible early in the disease course. Short-term intensive insulin therapy (SIIT) may rapidly normalize hyperglycemia and facilitate β-cell recovery in newly diagnosed T2DM. This systematic review evaluated the effects of SIIT on glycemic control, drug-free remission, β-cell function, durability, and safety. PubMed/MEDLINE, Scopus, and Web of Science were searched for English-language randomized controlled trials published during the five-year period ending in April 2026. Four trials met the eligibility criteria. Because interventions, remission definitions, maintenance strategies, and follow-up periods differed substantially, study-level effect estimates, 95% confidence intervals, and p values were synthesized without statistical pooling. SIIT consistently improved early glycemic control, β-cell function, and insulin sensitivity. In one 245-participant trial, medication-supported hemoglobin A1c (HbA1c) below 6.5% at three months was achieved by 78.7% of participants receiving SIIT plus metformin-pioglitazone versus 59.0% receiving SIIT alone (adjusted p < 0.05); however, 12-month drug-free remission rates were similar at 50.0% and 50.6%, respectively (p = 0.972). Another trial found that linagliptin-metformin maintenance after SIIT increased the adjusted odds of achieving HbA1c below 7.0% at 48 weeks (odds ratio 2.78, 95% confidence interval 1.37-5.65; p = 0.005), although this represented medication-supported glycemic control rather than remission. In a two-year trial, induction SIIT improved β-cell function and insulin sensitivity (all p ≤ 0.0004), but repeated intermittent SIIT did not improve the Insulin Secretion-Sensitivity Index-2 (adjusted difference -35, 95% confidence interval -66 to -3; p = 0.03). Severe hypoglycemia was not reported in trials providing detailed safety data, and transient weight gain was not consistently demonstrated. SIIT may therefore serve as a selective metabolic induction strategy in early T2DM, but durable remission remains uncertain and may depend on effective sequential treatment. Standardized remission definitions, validated response predictors, and longer comparative trials are required before routine implementation.

Type 2 diabetes mellitus (T2DM) is often linked to metabolic dysfunction-associated steatotic liver disease (MASLD), a metabolic liver condition defined by excessive lipid deposition within hepatocytes and is frequently accompanied by increased circulating liver enzyme levels. Dipeptidyl peptidase-4 (DPP-4) inhibitors, such as linagliptin, may exert pleiotropic effects on hepatic metabolism; however, their effects on liver enzyme profiles remain uncertain. This systematic review and meta-analysis aimed to evaluate the impact of linagliptin on liver enzymes, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT), in patients with T2DM. A systematic literature search was performed across five electronic databases up to 11 May 2026 following the PRISMA 2020 guidelines. Randomized controlled trials and cohort studies were included, and pooled mean differences (MDs) were calculated using random-effects models. Eight studies involving 1262 participants were analyzed. Linagliptin was associated with a modest reduction in AST (MD -1.58 U/L, 95% CI -2.85 to -0.31) with low heterogeneity, whereas the change in ALT was not statistically significant (MD -1.86 U/L, 95% CI -4.14 to 0.42), and substantial heterogeneity was observed. No significant effects were observed for GGT, while evidence for ALP was limited to a single study and was insufficient to determine the effect of linagliptin. Overall, linagliptin demonstrated limited and inconsistent effects on liver enzyme profiles.
