Clinical Trials

Multiple Phase I clinical trials evaluate the comparative pharmacokinetic properties and bioequivalence of oral Lisinopril formulations in healthy volunteers. Sponsoring organizations include pharmaceutical entities such as Pharmtechnology LLC, ClinPharmInvest LLC, and Bright Future Pharmaceuticals Factory, alongside academic institutions like the Chinese University of Hong Kong. These studies comprise both completed trials and entries with an unknown recruitment status.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Lisinopril dihydrate functions as a potent competitive inhibitor of angiotensin-converting enzyme, preventing the cleavage of angiotensin I into angiotensin II and suppressing downstream aldosterone secretion. This biochemical blockade attenuates vascular smooth muscle contraction and lowers peripheral resistance, providing the pharmacological rationale for its evaluation in bioequivalence trials in healthy subjects for the management of hypertension and congestive heart failure.

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).
