GlobalRPh Clinical Reference Library

Endocrinology, Diabetes & Metabolic Health Resource Center

Diabetes calculators and drug classes, insulin resources, obesity and cardiometabolic tools, thyroid and parathyroid references, adrenal and pituitary content, bone and vitamin D resources, testosterone and menopause material, and current GlobalRPh endocrine articles.

Clinical background

Endocrine disorders rarely stay confined to one organ system

Hormonal and metabolic disorders often overlap with cardiovascular disease, kidney disease, reproductive health, bone health, nutrition, obesity, medication effects, and long-term risk. Diabetes care now incorporates glucose technology, cardiorenal risk reduction, weight management and individualized pharmacotherapy; thyroid disease intersects with pregnancy, cardiovascular status and bone health; and adrenal, pituitary and gonadal disorders require careful biochemical and clinical interpretation.

This redesigned portal brings GlobalRPh’s endocrine calculators, diabetes drug tables, insulin references, thyroid tools, hormone resources, body-composition calculators and newer 2025–2026 articles into one organized clinical center. Older resources remain accessible, but they are distinguished from newer content so users can see where we are actively updating the library.

Core GlobalRPh calculators

Endocrinology tools already available on the site

Diabetes mellitus

Glucose assessment, insulin resources and antihyperglycemic drug classes

The original portal contains an extensive diabetes pharmacotherapy library. The revised layout keeps all of those classes but makes current technology and newer drug classes easier to find.

Antihyperglycemic drug-class library

GLP-1 receptor agonists GLP-1 / Incretin Mimetics
SGLT2 inhibitors SGLT2 Inhibitors
DPP-4 inhibitors DPP-4 Inhibitors
Sulfonylureas Sulfonylureas
Meglitinides Meglitinides
Thiazolidinediones Glitazones / TZDs
Alpha-glucosidase inhibitors Alpha-Glucosidase Inhibitors
The long-standing Diabetic Database remains available because it contains useful historical insulin and diabetes material, but its displayed references include ADA guidance from 2001–2002. We are treating that page as an update project rather than the current starting point for diabetes-management recommendations.

Obesity, insulin resistance & cardiometabolic health

Body composition, weight-management tools and metabolic-risk content

Obesity and insulin resistance now deserve their own endocrine subsection rather than being scattered between Nutrition, Cardiology and diabetes pages.

The existing GlobalRPh Weight Management Agents table still contains lorcaserin (Belviq), which is no longer marketed in the United States after the FDA requested its withdrawal in 2020. We are keeping the page linked for continuity while it is rebuilt around current obesity pharmacotherapy.

Thyroid & parathyroid

Hypothyroidism, hyperthyroidism, thyroid cancer and parathyroid imaging

The levothyroxine calculator remains useful as a basic educational tool, but the current page is still labeled “BETA” and includes older background references. We plan to update weight-based dosing, pregnancy, older adults, cardiac disease, absorption interactions, central hypothyroidism and monitoring language when that calculator is rebuilt.

Adrenal, pituitary & corticosteroid physiology

Adrenal incidentalomas, aldosterone, glucocorticoids and endocrine replacement

The older portal had no dedicated adrenal or pituitary section despite having related GlobalRPh drug references and newer articles elsewhere on the site.

Bone, osteoporosis & vitamin D

Bone-mineral assessment and endocrine pharmacotherapy

Reproductive hormones & menopause

Testosterone, hypogonadism and menopausal hormone therapy

GlobalRPh endocrinology article library

Recent diabetes, thyroid, obesity, adrenal and hormone articles

The old portal’s article area was concentrated in 2024. The revised library surfaces the strongest newer Endocrinology-category and closely related GlobalRPh material.

Planned GlobalRPh updates

Areas we’re continuing to improve in the Endocrinology library

GlobalRPh has maintained endocrine calculators and drug tables for many years while the field has changed rapidly. As we work through this section, we plan to update the oldest diabetes, thyroid, obesity and hormone pages first, then connect them more tightly to current product labeling, guidelines and newer GlobalRPh articles.

Pages we plan to refresh

  • Diabetic Database: this is one of our highest-priority endocrine updates. The current page still displays ADA references from 2001–2002 and older insulin/product information. We plan to rebuild it around current diagnostic criteria, CGM, time in range, insulin technology, cardiorenal risk, obesity therapy and the 2026 diabetes standards.
  • Levothyroxine Dosing Calculator: the current calculator remains labeled BETA and includes older background references. We plan to update initial dosing, older adults, cardiac disease, obesity/body composition, pregnancy, central hypothyroidism, absorption interactions, formulation issues and monitoring.
  • Weight Management Agents: the current table contains historical products, including lorcaserin/Belviq, that no longer belong in a current U.S. treatment table. We plan to rebuild this around contemporary anti-obesity pharmacotherapy, labeling, indications, contraindications and long-term treatment principles.
  • GLP-1 / incretin drug table: we plan to expand this beyond the older GLP-1 agonist framework to make current GLP-1, GIP/GLP-1 and evolving incretin strategies easier to compare, while separating diabetes and obesity indications.
  • SGLT2 inhibitors: we plan to update diabetes, heart-failure and kidney-disease indications, renal thresholds, perioperative considerations, ketoacidosis risk and current product labeling.
  • Insulin class pages: we plan to re-check currently marketed formulations, onset/duration language, concentrated products, pump compatibility, newer ultra-rapid products and the relationship to automated insulin delivery.
  • Insulin Mixing Tool: we plan to verify compatibility guidance against currently marketed insulin formulations and more clearly distinguish syringe mixing from pump/reservoir use.
  • Thyroid Hormone / Antithyroid tables: we plan to update current products, monitoring, pregnancy considerations, major interactions, thyroid-cancer contexts and safety language.
  • Parathyroid Scan Score Calculator: we plan to re-review the score against contemporary parathyroid imaging and surgical localization practice and clarify where it is most useful.
  • ADAM and AMS tools: we plan to preserve the validated screening instruments while strengthening the explanation that symptoms require biochemical confirmation and evaluation for reversible causes before testosterone treatment decisions.
  • Testosterone Products: we plan to update currently marketed formulations, REMS or administration requirements where applicable, cardiovascular and hematologic monitoring, fertility considerations, contraindications and transfer-risk precautions for topical products.
  • Hormone Replacement / Postmenopausal Agents: we plan to modernize product tables around contemporary menopausal hormone therapy, route-specific considerations, nonhormonal options and current prescribing guidance.
  • Osteoporosis / bisphosphonate tables: we plan to align these with current sequencing concepts, anabolic therapy, denosumab discontinuation considerations, renal function and contemporary fracture-risk management.
  • Endocrine / Other: we plan to turn this older miscellaneous page into a more coherent adrenal-pituitary reference with current replacement therapies and monitoring.
Our goal is to keep the practical GlobalRPh tools that clinicians already use while making it immediately clear which pages reflect current endocrine practice and which pages are actively being refreshed.

Supporting GlobalRPh resources

Related clinical portals, drug references and laboratory support

Older endocrine resources remain accessible during the update process

We are not removing older calculators simply because their background references need updating. Where a tool still has practical value, the new portal keeps it discoverable and identifies it in our planned-update section. This allows us to modernize the clinical logic and references without breaking useful internal links or hiding longstanding GlobalRPh resources.
