Overview

Levamlodipine besylate is the levo-rotatory (S-) isomer of amlodipine, a long-acting dihydropyridine calcium channel blocker used as an oral antihypertensive and anti-anginal agent. The Innovent Biologics product is supplied as 2.5-milligram tablets in boxes of 21, labeled for hypertension and coronary heart disease. As a single-isomer product, levamlodipine is often discussed in procurement conversations because the dose is documented as roughly half that of racemic amlodipine for an equivalent hemodynamic effect.

For B2B distributors, the procurement lens on this product is broader than a simple tablet count. Levamlodipine is a prescription medication in most jurisdictions, so the procurement chain must consider prescription status, manufacturing licensing, and the destination market's regulatory pathway before pricing negotiations begin.

What Buyers Should Confirm Before Ordering

The first procurement item is regulatory classification. In most major markets, levamlodipine is a prescription-only medication, and the manufacturing site must hold a current Good Manufacturing Practice (cGMP) certificate recognized in the destination market. A Certificate of Pharmaceutical Product (CPP) is usually the most efficient single document for cross-border clearance because it summarizes the registration status and the dosage form in a format that most national authorities accept. Buyers should request the most recent version of the CPP for the Innovent Biologics site before issuing a purchase order.

The second item is monograph alignment. Levamlodipine besylate is monographed in the Chinese Pharmacopoeia and several other national pharmacopoeias, and each monograph includes limits on residual solvents, related substances, and chiral purity. The certificate of analysis for each lot should show the chiral purity assay (typically not less than 99% S-isomer), the related-substances profile, the dissolution result, and content uniformity data. Buyers who do not see the chiral-purity number should request it; chiral purity is the defining analytical item for an isomer product.

Logistics and Lot Traceability

Logistics for a prescription antihypertensive is documentation-heavy. Tablets are typically packed in PVC/PVDC aluminum blisters inside a printed carton, with three strips of seven tablets per box. The carton must carry the lot number, manufacture date, expiration date, and the manufacturer's licensing reference. Shipping should respect the labeled storage range, typically below 30 degrees Celsius in a dry place, and temperature-controlled containers are recommended for tropical or summer routes.

For long-term supply, the buyer should also confirm that future lots will match the registered formulation. In markets with bioequivalence requirements, any change to excipient composition or the manufacturing site triggers a new bioequivalence study. Buyers should plan for it rather than discover the requirement at the receiving dock.

FAQ

Q: What is the labeled strength of the Innovent Biologics product?

A: The product is labeled at 2.5 milligrams of levamlodipine per tablet, supplied as 21 tablets per box.

Q: Why is the labeled dose lower than the racemic version?

A: Levamlodipine is the S-isomer of amlodipine. The S-isomer carries the principal calcium channel blocking activity, and the labeled dose is correspondingly lower than the racemic product. The manufacturer's prescribing information is the controlling reference for dose equivalence.

Q: What is the most important analytical item?

A: Chiral purity is the defining analytical item. The certificate of analysis should show the S-isomer assay, related substances, dissolution, and content uniformity. Buyers who do not see the chiral-purity number should request it from the manufacturer.

Q: Is levamlodipine a prescription drug in most markets?

A: In most major markets levamlodipine is prescription-only, so the manufacturing site must hold a cGMP certificate recognized in the destination market and the import file typically requires a Certificate of Pharmaceutical Product.
