> Applications
Prostaglandin E1 (Alprostadil) is used by pharmaceutical and research organizations developing prostaglandin analog formulations, reference methods, and impurity-control strategies. API supply is intended for qualified buyers who will confirm dosage form, prostaglandin stability needs, impurity requirements, pharmacopoeial approach, and finished-dose registration obligations in their own markets.
Prostaglandin analog formulation research
A 1997 New England Journal of Medicine article reported a randomized prospective double-blind placebo-controlled trial evaluating transurethral alprostadil in formulation research (N Engl J Med, doi:10.1056/NEJM199701023360101, n=1511). This supports the need for carefully controlled Prostaglandin E1 (Alprostadil) API quality in prostaglandin analog formulation and analytical-development programs.
Analytical and impurity-control development
Buyers typically evaluate assay, related substances, residual solvents, water content, identity, prostaglandin stability profile, microbial limits, and stability behavior before moving from sample quantities to pilot or commercial batches. We supply API only, not finished topical products, injectable products, urethral systems, compounded products, or branded medicines.
