Clinical Trials

Numerous clinical trials evaluate amiloride across various cardiovascular, renal, metabolic, neuropsychiatric, and oncological conditions, such as hypertension, proteinuria, diabetic nephropathies, cystic fibrosis, lithium-induced nephrogenic diabetes insipidus, and triple-negative breast cancer. Spanning Early Phase 1 to Phase 4 investigations, these studies are primarily sponsored by academic medical centers, university hospital trusts, and public research institutes. Across these cohorts, recruitment statuses vary from active and recruiting to completed and terminated.

Check the Amiloride HCl dihydrate product page for in-depth specifications, including solubility, stock solutions, MOA, and working concentrations.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Amiloride HCl dihydrate directly binds to and inhibits epithelial sodium channels (ENaC) in the renal nephron, thereby blocking luminal sodium reabsorption and downstream Na+/K+ ion exchange. This selective channel blockade promotes renal natriuresis while sparing potassium ions, providing the physiological rationales for its therapeutic application in clinical trials targeting hypertension, proteinuria, and cardiovascular disease.

Appendix RUO and cGMP Quality Standards

Quality Dimension RUO (Research Use Only) cGMP (Current Good Manufacturing Practice)
Clinical Applicability Prohibited in human clinical trials or medical diagnostics. Mandatory for human clinical trials (Phase I–III) and therapies.
Regulatory Status Non-regulated grade; exempt from drug manufacturing laws. Legally enforced by health authorities (e.g., FDA, EMA, NMPA).
Facility Environment Unclassified analytical or research laboratories. Validated Cleanrooms (ISO Class 5–8) with continuous monitoring.
Quality Control Basic purity and activity testing. Rigorous safety release testing (Sterility, Endotoxin, Mycoplasma).
Process Validation Basic equipment calibration; no process validation required. Full qualification (IQ/OQ/PQ) and complete batch records.
Quality Assurance Vendor self-declared without required formal QMS. Mandatory QA/QC unit, Change Control, CAPA, and vendor audits.
Regulatory Impact High risk of IND rejection if used as a critical raw material. Required for IND/NDA filings, supported by Drug Master Files (DMF).

Footnotes

Regulatory Note: Governed by FDA (21 CFR Parts 210/211/312), EMA (EudraLex Vol 4), ICH Guidelines (E6/Q7/Q9/Q10), and compendial standards (USP <71>/<85>/<1043>).
