Company overview

Italian manufacturing heritage. Industry 4.0 production.

As part of the Alfa Intes group, Hyteka combines six decades of pharmaceutical heritage with state-of-the-art automated filling technologies to deliver tech-transfer and advanced manufacturing for injectables.

We pair Italian manufacturing heritage, Industry 4.0 production lines, and a regulatory infrastructure aligned with international standards — bringing partners to market with speed, quality and confidence.

Two manufacturing plants in Italy, 20,000 m² combined, running 4,000–10,000 units/hour across 4 dedicated cleaning rooms.

Production flow

Five macro-phases, vertically integrated — engineered to mitigate particulate and microbiological cross-contamination.

1

Pure steam & WFI production

All filling, sterilisation and wash operations use Water for Injection from a dedicated closed-loop system, continuously monitored to Pharmacopoeia requirements. Pure steam supports all autoclave cycles.

2

Aseptic filling

Automated aseptic fill-finish in Class A GMP (ISO 5) isolator environments with continuous monitoring. High-precision pumps are calibrated for non-Newtonian, high-viscosity fluids, engineered to eliminate micro-bubbles — critical for intraocular products.

3

Sterilisation

Validated moist-heat sterilisation (steam autoclave) cycles developed to ISO 17665, optimised for full microbiological inactivation while minimising thermal stress on the polymer chain.

4

Automated optical inspection

100% automated inspection on every unit, across seven critical quality parameters:

  • 01Filling volume accuracy
  • 02Suspended particles
  • 03Flange integrity
  • 04Solution colour conformance
  • 05Stopper traces & residues
  • 06Plunger integrity
  • 07Stopper positioning

Automated release records, batch-level traceability.

5

Secondary packaging & serialisation

Modular automated lines in one continuous flow: cartoning, labelling, leaflet insertion, tamper-evident sealing, blister packaging and aggregation. Full serialisation and track-and-trace, compliant with EU FMD.

Collaboration models

Three ways to partner, one continuous relationship.

Whatever you bring to the table — a finished formulation, a Technical File, or only a concept — our teams work as an extension of yours across the stages that matter.

Private labelling

CE-marked OVDs (ocular viscoelastics), viscoelastics and surgical dyes, ready to brand and sell under your label. CE-marked under MDR EU 2017/745. No R&D investment — the shortest route to market.

No R&D required

Contract manufacturing

Combination of external formulation and Technical File assets with comprehensive on-site capabilities. End-to-end tech-transfer support guides the transition, enabling scalable progression from pilot batches to commercial volumes.

You bring the formulation

Contract development & manufacturing

Full end-to-end partnership — from formulation concept through scale-up and regulatory filing to commercial supply. Our R&D and regulatory teams work as an extension of yours.

Services

Development, regulatory and quality — under one roof.

Five capability areas support partners across the full product lifecycle, from feasibility through commercial-scale production.

Development services

From formulation concept to commercial supply — every protocol is designed for the specific challenges of injectable products, across four validated stages.

Formulation & feasibility

Raw material selection, rheology characterisation, lab-scale trials.

Process development & scale-up

Tech-transfer to Class A lines, pilot batches, filling parameter tuning.

Validation & registration

Process validation (IQ/OQ/PQ), ICH-compliant stability, Technical File and dossier authoring.

Commercial supply

Serialised batch release, secondary packaging, qualified global logistics.

Hyaluronic Acid: Core Expertise

High molecular weight hyaluronic acid, mastered.

Polymers beyond 2.5 million Daltons carry exceptional viscoelastic and biocompatible properties — and exceptional manufacturing risk. Our protocols are built around the chain, not against it.

>2.5MDa

Non-degradative solubilisation

Calibrated mixing temperature and speed fully hydrate the polymer without the shear degradation that would fragment the chain.

Pseudoplastic rheology

High viscosity at rest protects the corneal endothelium; under pressure, the gel turns fluid — lowering the extrusion force needed at injection.

Class A aseptic filling

Chains above 2.5 MDa are thermolabile. We sterile-filter and fill in Class A (ISO 5) cleanrooms — no terminal heat to collapse viscosity.

Total batch screening

Molecular weight, viscosity, syringe-ability, endotoxin and bioburden verified on every lot — guarding against Toxic Anterior Segment Syndrome.

Our partners

Trusted by partners who need it done exactly their way.

Partners choose Hyteka because flexibility is part of the foundation, not an afterthought. From formulation and concentration to container format, label and carton, each element can be shaped around your brand and specification. Batch sizes can also adapt to the pace of your launch, supporting smaller start-up runs as well as larger commercial volumes, while automated aseptic filling in a Class A (ISO 5) environment keeps every step precise, traceable and consistently controlled.

Let's talk partnership

Partnering to fill the future.

Whether you are a distributor looking for a ready-to-brand OVD portfolio, or a pharmaceutical company seeking a dedicated ophthalmic CDMO partner, Hyteka is ready to discuss your specific needs.
