Patterns of initial and first-intensifying antidiabetic drug utilization among patients with type 2 diabetes mellitus in Scotland, 2010-2020: A retrospective population-based cohort study. Diabetes Obes Metab 2024; 26:2684-2694. [PMID: 38558305 DOI: 10.1111/dom.15584] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Revised: 03/13/2024] [Accepted: 03/19/2024] [Indexed: 04/04/2024]
Abstract
AIM To evaluate the utilization and prescribing patterns of antidiabetic drugs (ADDs) for patients with type 2 diabetes mellitus (T2DM) at treatment initiation and first intensification. METHODS A retrospective cohort study was performed using linked routinely collected data of patients with T2DM who received ADDs between January 2010 and December 2020 in Scotland. The prescribing patterns were quantified using frequency/percentages, absolute/relative change, and trend tests. RESULTS Overall, 145 909 new ADD users were identified, with approximately 91% (N = 132 382) of patients receiving a single ADD at first treatment initiation. Metformin was the most often prescribed monotherapy (N = 118 737, 89.69%). A total of 50 731 patients (39.40%) who were started on metformin (N = 46 730/118 737, 39.36%) or sulphonylurea (SU; N = 4001/10 029, 39.89%) monotherapy had their treatment intensified with one or more additional ADD. Most initial-metformin (45 963/46 730; 98.36%) and initial-SU users (3894/4001; 97.33%) who added further drugs were intensified with single ADDs. SUs (22 197/45 963; 48.29%) were the most common first-intensifying monotherapy after initial metformin use, but these were replaced by sodium-glucose cotransporter-2 (SGLT2) inhibitors in 2019 (SGLT2 inhibitors: 2039/6065, 33.62% vs. SUs: 1924/6065, 31.72%). Metformin was the most frequently added monotherapy to initial SU use (2924/3894, 75.09%). Although the majority of patients received a single ADD, the use of combination therapy significantly increased over time. Nevertheless, there was a significant increasing trend towards prescribing the newer ADD classes (SGLT2 inhibitors, dipeptidyl peptidase-4 inhibitors) as monotherapy or in combination compared with the older ones (SUs, insulin, thiazolidinediones) at both drug initiation and first intensification. CONCLUSIONS An overall increasing trend in prescribing the newer ADD classes compared to older ADDs was observed. However, metformin remained the most commonly prescribed first-line ADD, while SGLT2 inhibitors replaced SUs as the most common add-on therapy to initial metformin use in 2019.

An observational multi-center study on type 2 diabetes treatment prescribing pattern and patient adherence to treatment. Sci Rep 2023; 13:23037. [PMID: 38155289 PMCID: PMC10754831 DOI: 10.1038/s41598-023-50517-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Accepted: 12/20/2023] [Indexed: 12/30/2023] Open
Abstract
In 2021, the International Diabetes Federation (IDF) reported that the prevalence of diabetes in Pakistan was 9.6%, higher than the global average. However, adherence to treatment guidelines, e.g., American Diabetes Association and Pakistan Endocrine Society and prescription patterns for Oral anti-diabetes (OAD), is poorly understood in Pakistan. Therefore, this study aimed to examine the prescribing practices of anti-diabetic medications, an association of lifestyle modification with drugs prescribed, and their effectiveness in preserving ideal glycemic levels in diabetic patients undergoing treatment in tertiary care teaching hospitals in rural and urban Pakistan. In this cross-sectional study, data were collected from prescriptions of outpatient diabetic patients from different rural and urban tertiary care hospitals between October 2021 and February 2022. 388 participants were enrolled in the study for a detailed interview on prescription evaluation and glycemic control. The coinvestigators conducted an interview with the patient and used a pre-validated questionnaire to collect the data. The relationship between following treatment guidelines and clinical and demographic factors was found using chi-square tests for bivariate analyses. The study reported that out of 388, the mean ages of the patients were 48 ± 12.4, and the majority were female. It was observed that 60.1% and 66.5% have uncontrolled fasting and random blood glucose, respectively. The education level of the study participants was also below par to have a complete understanding of the medical condition and self-management therapy. Even though they were taking the right medications-an average prescription regimen included 5.08 medications-52.1% of the studied people had glycated haemoglobin (HbA1c) levels higher than the therapeutic threshold set by the International Diabetes Federation. In this modern era, it was observed that the prescribing trend was still focused on traditional therapeutic options Biguanides, sulfonylureas, and dipeptidyl peptidase-4 inhibitors were prescribed in 64.6% of the patients. A significant association was found between glycemic control and body mass index, adherence to lifestyle modifications, and the number of medications prescribed (p-value < 0.05). The study reveals that Pakistan's prescribing practices do not align with international and national guidelines, leading to a high prevalence of uncontrolled diabetes and widespread use of polypharmacy among patients. To address this issue, policymakers should prioritize establishing a comprehensive national diabetes action plan. Additionally, there is a pressing need to develop diabetes education and awareness programs emphasizing the importance of lifestyle modifications for effective diabetes management.

Eur J Clin Invest 2023; 53:e13997. [PMID: 37002856 DOI: 10.1111/eci.13997] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 02/09/2023] [Accepted: 03/22/2023] [Indexed: 04/11/2023]
Abstract
BACKGROUND There is a lack of consensus on prescribing alternatives to initial metformin therapy and intensification therapy for type 2 diabetes mellitus (T2DM) management. This review aimed to identify/quantify factors associated with prescribing of specific antidiabetic drug classes for T2DM. METHODS Five databases (Medline/PubMed, Embase, Scopus, Web of Science) were searched using the synonyms of each concept (patients with T2DM, antidiabetic drugs and factors influencing prescribing) in both free text and Medical Subject Heading (MeSH) forms. Quantitative observational studies evaluating factors associated with antidiabetic prescribing of metformin, sulfonylurea, thiazolidinedione, Dipeptidyl-peptidase 4 inhibitors (DPP4-I), sodium glucose transporter 2 inhibitors (SGLT2-I), Glucagon-Like peptide receptor agonist (GLP1-RA) and insulin in outpatient settings and published from January 2009 to January 2021 were included. Quality assessment was performed using a Newcastle-Ottawa scale. The validation was done for 20% of identified studies. The pooled estimate was measured using a three-level random-effect meta-analysis model based on odds ratio [95% confidence interval]. Age, sex, body mass index (BMI), glycaemic control (HbA1c) and kidney-related problems were quantified. RESULTS Of 2331 identified studies, 40 met the selection criteria. Of which, 36 and 31 studies included sex and age, respectively, while 20 studies examined baseline BMI, HbA1c and kidney-related problems. The majority of studies (77.5%, 31/40) were rated as good and despite that the overall heterogeneity for each studied factor was more than 75%, it is mostly related to within-study variance. Older age was significantly associated with higher sulfonylurea prescription (1.51 [1.29-1.76]), yet lower prescribing of metformin (0.70 [0.60-0.82]), SGLT2-I (0.57 [0.42-0.79]) and GLP1-RA (0.52 [0.40-0.69]); while higher baseline BMI showed opposite significant results (sulfonylurea: 0.76 [0.62-0.93], metformin: 1.22 [1.08-1.37], SGLT2-I: 1.88 [1.33-2.68], and GLP1-RA: 2.35 [1.54-3.59]). Both higher baseline HbA1c and having kidney-related problems were significantly associated with lower metformin prescription (0.74 [0.57-0.97], 0.39 [0.25-0.61]), but more insulin prescriptions (2.41 [1.87-3.10], 1.52 [1.10-2.10]). Also, DPP4-I prescriptions were higher for patients with kidney-related problems (1.37 [1.06-1.79]) yet lower among patients with higher HbA1c (0.82 [0.68-0.99]). Sex was significantly associated with GLP1-RA and thiazolidinedione prescribing (F:M; 1.38 [1.19-1.60] and 0.91 [0.84-0.98]). CONCLUSION Several factors were identified as potential determinants of antidiabetic drug prescribing. The magnitude and significance of each factor differed by antidiabetic class. Patient's age and baseline BMI had the most significant association with the choice of four out of the seven studied antidiabetic drugs followed by the baseline HbA1c and kidney-related problems which had an impact on three studied antidiabetic drugs, whereas sex had the least impact on prescribing decision as it was associated with GLP1-RA and thiazolidinedione only.

Assessing Therapeutic Choices and Adherence to Antidiabetic Therapy in Naïve Patients: A Retrospective Observational Study in a Local Health Authority of the Piedmont Region (Italy). Healthcare (Basel) 2023; 11:healthcare11111655.

Abstract
Due to its prevalence and socio-economic burden on health systems, diabetes mellitus (DM) is considered a major health emergency. This retrospective, observational study aimed to describe a population of DM-naïve patients of the Local Health Authority (LHA) ASL TO4 Regione Piemonte and the prescriptive behavior of LHA general practitioners. Drug dispensing data collected between January 2018 and December 2021 was analyzed. Adult patients were included if they received their first prescription for an antidiabetic drug (AD) in 2019 and had ≥2 prescriptions/year of ADs during the follow-up. Patients who started antidiabetic therapy with metformin were selected to investigate comorbidities, medication adherence, and first treatment intensification. Comorbidities were identified through a modified version of the Rx-Risk Index; adherence was measured as the continuous measure of medication availability (CMA). Among 1927 DM-naïve patients, 1361 started therapy with metformin. Most of them received drugs related to cardiovascular diseases, hypertension, and infectious diseases during the study period. Median CMA was 58.8%, with the majority of patients being partially adherent to ADs (40 ≤ CMA < 80). Initial antidiabetic therapy was mostly modified (switch, add-on) with SGLT-2 inhibitors and sulfonylureas. These findings help to identify areas of intervention to improve the use of ADs in the LHA.

Abstract
Background:
Persistent hyperglycemia in diabetes mellitus (DM) is considered as the leading cause of morbidity and mortality associated with both microvascular and macrovascular complications and has a greater economic impact. This study aimed to assess the impact of socioeconomic status, prescribing patterns, and patient compliance in type 2 diabetes mellitus patients.
Method:
This study was carried out in the department of medicine and diabetic clinic of Hakeem Abdul Hameed (HAH) Centenary Hospital at Hamdard University, New Delhi, India. We conducted a prospective observational study on prescribing patterns and monitoring of adverse drug reactions (ADRs) in patients with type 2 DM (T2DM) taking standard care. We enrolled 150 confirmed cases and data was obtained from pre-validated questionnaires and then coded and analyzed to observe the association between variables.
Results:
The glycosylated haemoglobin level in 56 % of cases was between 6.4 to 8.0 and cardiovascular complications were observed as the major comorbidities. 45.33 % of cases were on mono drug therapy and Metformin (23. 52 %) was the drug of choice followed by Glimepiride (23.52 %). Among the dual drug therapies, Sitagliptin with Metformin and in triple-drug therapy, Glimepiride concurrent with Metformin and Voglibose was the most preferred drug in the treatment of T2DM. Sitagliptin was observed to be a major patient burden (46.213 USD). In only 7.33 % of cases, we observed definite ADR in T2DM patients. Underprivileged awareness, mainly due to low literacy, was a major concern in the development of new cases of T2DM.
Conclusion:
We observed better patient compliance and disease awareness program is required to be implemented. The use of oral hypoglycaemic drugs is still dominant in clinical practice and cardiovascular disorders as comorbidities emerge as a greater challenge in terms of patient outcome and cost burden.

Abstract
The aim of this review was to examine changes in the use of diabetes medicines prescribed to treat type 2 diabetes in the primary care setting. Five electronic databases were searched using strict inclusion/exclusion criteria. The quality of eligible studies was appraised using the Newcastle-Ottawa Scale. Findings show the trend has been away from using sulfonylurea and towards the use of metformin. The introduction of newer drugs has not shifted treatment outcomes and glycaemic control. It was not possible to determine how clinicians make choices about the medicines they prescribe for T2DM, or what influences those choices.

Abstract
AIMS To determine the prescription patterns of antidiabetic medications and the variables associated with their use in a Colombian population. METHODS A cross-sectional study using a systematized database of approximately 3.5 million affiliates of the Colombian Health System. Patients of both genders and all ages treated uninterruptedly with antidiabetic medications for three months (June-August 2015) were included. A database was designed that included sociodemographic, pharmacological, comedication, and cost variables. RESULTS A total of 47,532 patients were identified; the mean age was 65.5 years, and 56.3% were women. Among the patients, 56.2% (n=26,691) received medication as monotherapy. The most prescribed medications were metformin, 81.3% (n=38,664), insulins, 33.3% (n=15,848), and sulfonylureas, 21.8% (n=10,370). Among the patients, 92.8% received comedications, including antihypertensives (79.7%), hypolipemiants (65.5%), antiplatelet drugs (56.3%), analgesics (33.9%), antiulcerants (33.1%), and thyroid hormone (17.3%). The cost per 1000 inhabitants/day was $1.21 USD for metformin, $3.89 USD for insulins, and $0.02 USD for glibenclamide. CONCLUSIONS Generally, rational prescription habits predominated, however in some cases an overuse of comedications (such as antiulcer drugs) and a large group of patients with high cost formulations were observed. Subsequent effectiveness and cost-benefit analyzes are required.

Abstract
OBJECTIVES The objectives were to examine long-term changes in type 2 diabetes patient characteristics, diabetes treatment, control and complications in general practices. METHODS All type 2 diabetes patients were identified in a representative general practice database (Disease Analyser, Germany) in three periods (01/2008-12/2008: n = 90.866, 818 practices, mean age (SD): 67.6 (12.1) years, 51% males; 01/2012-12/2012: n = 179.923, 1.158 practices, 68.3 (12.6) years, 51% males; 10/2015-09/2016: n = 201.667, 1.184 practices, 68.2 (12.9) years, 52% males). Chi-square and Wilcoxon rank-sum tests were used for testing differences (2008 vs. 2015/16). RESULTS The mean number of type 2 patients per practice increased (2008: 111; 2015/16: 170). The proportion of retirees declined (74% vs. 61%) and patients in the working population increased (18% vs. 28%) (all p < 0.001). There were no relevant changes in mean HbA1c (7.1% vs. 7.2%), fasting blood glucose (141 mg/dl vs. 144 mg/dl) and BMI (31 kg/m2 vs. 32 kg/m2), whereas total cholesterol (204 mg/dl vs. 196 mg/dl) and triglycerides (159 mg/dl vs. 153 mg/dl) slightly declined (all p < 0.001). Prescription use of metformin, dipeptidyl peptidase-4 (DPP-4) and sodium dependent glucose transporter-2 (SGLT-2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists enlarged (dual or triple combinations) while sulfonylurea use decreased. Prevalence of polyneuropathy (6.2% vs. 8.6%), nephropathy (1.9% vs. 3.2%) and depression (7.6% vs. 10.0%) rised (all p < 0.001). CONCLUSIONS General practitioners play a key role in diabetes care, increasingly treating type 2 diabetes patients in the working population. There was no change in glycemic control over the study period (2008-2016). The use of glucose-lowering drug combinations increased and microvascular complications were more often recorded.

Abstract
OBJECTIVES Dapagliflozin is an inhibitor of the human sodium-glucose co-transporter 2 (SGLT2) that has been shown to improve glycaemic control in patients with type 2 diabetes mellitus (T2DM). This study aimed to evaluate the characteristics and treatment patterns of dapagliflozin users in comparison to users of other anti-diabetic (AD) treatments in Germany. METHODS Data from patients with T2DM initiating at least one prescription for dapagliflozin or other AD therapy between November 2012 and April 2014 were collected from the IMS German Disease Analyzer database. RESULTS The use of dapagliflozin combination therapy (n=1034; 74%) was more common than monotherapy (n=371; 26%). In comparison with other AD therapy users, a higher percentage of dapagliflozin users were ⩽64years of age (62.3% vs. 36.4%), and a higher proportion were male (59.1% vs. 53.6%). The average duration of diabetes was comparable between dapagliflozin patients and other AD therapy users (5.7yearsvs. 5.5years), however higher levels of HbA1c were found in dapagliflozin users (8.2% (66mmol/mol) vs. 7.5% (58mmol/mol). For the vast majority (71.5% of 10mg dapagliflozin users and 88.9% of 5mg users), dapagliflozin was prescribed in combination with other AD therapy. CONCLUSIONS Patients starting on dapagliflozin differed in several demographic and health-related respects to patients starting another AD therapy during the same period. Dapagliflozin was predominantly used as a component of combination therapy, adding on to existing therapy. After initiation, switching to other AD treatments or adding to therapy was comparatively rare during the first year.

Prescription of oral hypoglycemic agents for patients with type 2 diabetes mellitus: A retrospective cohort study using a Japanese hospital database. J Diabetes Investig 2016; 8:227-234.

Abstract
Aims/Introduction In treatment algorithms of type 2 diabetes mellitus in Western countries, biguanides are recommended as first‐line agents. In Japan, various oral hypoglycemic agents (OHAs) are available, but prescription patterns are unclear. Materials and Methods Data of 7,108 and 2,655 type 2 diabetes mellitus patients in study 1 and study 2, respectively, were extracted from the Medical Data Vision database (2008–2013). Cardiovascular disease history was not considered in study 1, but was in study 2. Initial choice of OHA, adherence to its use, effect on glycated hemoglobin levels for 2 years and the second choice of OHA were investigated. Results In study 1, α‐glucosidase inhibitor, glinide and thiazolidinedione were preferentially medicated in relatively lower glycated hemoglobin cases compared with other OHAs. The two most prevalent first prescriptions of OHAs were biguanides and dipeptidyl peptidase‐4 inhibitors, and the greatest adherence was for α‐glucosidase inhibitors. In patients treated continuously with a single OHA for 2 years, improvement in glycated hemoglobin levels was greatest for dipeptidyl peptidase‐4 inhibitors. As a second OHA added to the first OHA during the first 2 years, dipeptidyl peptidase‐4 inhibitors were chosen most often, especially if a biguanide was the first OHA. In study 2, targeting patients with a cardiovascular disease history, a similar tendency to study 1 was observed in the first choice of OHA, adherence and the second choice of OHA. Conclusions Even in Japanese type 2 diabetes mellitus patients, a Western algorithm seems to be respected to some degree. The OHA choice does not seem to be affected by a cardiovascular disease history.

Abstract
BACKGROUND Levothyroxine (LT4) absorption is affected by concomitant ingestion of certain minerals, medications, and foods. It has been hypothesized that metformin may suppress serum thyrotropin (TSH) concentrations by enhancing LT4 absorption or by directly affecting the hypothalamic-pituitary axis. This study examined the effect of metformin ingestion on LT4 absorption, as assessed by serum total thyroxine (TT4) concentrations. METHODS A modified Food and Drug Administration LT4 bioequivalence protocol was applied to healthy, metformin-naïve, euthyroid adult volunteers. Following an overnight fast, 600 μg LT4 was administered orally. Serum TT4 concentrations were measured at baseline and at 0.5, 1, 1.5, 2, 4, and 6 h following LT4 administration. Measurements were performed before and after one week of metformin ingestion (850 mg three times daily). Peak serum TT4 concentrations, time to peak TT4 concentrations, and area under the concentration-time curve (AUC) were calculated. RESULTS Twenty-six subjects (54% men, 27% white, age 33 ± 10 years) were studied. There were no significant differences in peak serum TT4 concentrations (p = 0.13) and time to peak TT4 concentrations (p = 0.19) before and after one week of metformin use. A trend toward reduced TT4 AUC was observed after metformin ingestion (pre-metformin 3893 ± 568 μg/dL-min, post-metformin 3765 ± 588 μg/dL-min, p = 0.09). CONCLUSIONS LT4 absorption is unchanged by concomitant metformin ingestion. Mechanisms other than increased LT4 absorption may be responsible for the suppressed TSH concentrations observed in patients ingesting both drugs.
