Enteric Pills for Targeted Intestinal Release – OEM Wholesale from China Factory

Sourcing enteric coated pills? We handle custom formulations using premium HPMC excipients. Direct from 140,000 sqm Hebei facility. Fast leads to USA importers.

Why Procurement Managers Struggle with Enteric Pill Sourcing

I've seen it too many times. A pharma ops manager in the US gets specs from R&D for an enteric coated NSAID tablet. They search suppliers, find cheap options from unverified mills. Tablets crumble in stomach acid tests. Reformulation delays launch by months. Extra costs pile up.

Or worse, coatings flake during stability trials. FDA filing gets flagged. You're back to square one, burning budget on revalidation.

Common pitfalls hit hard. Low-solubility HPMC knockoffs don't form proper pH-sensitive films. Inferior plasticizers lead to brittleness in humid shipping containers. We've consulted on fixes for importers who ignored viscosity grades – ended up with patchy dissolution profiles.

Supply chain snaps too. Factories promise 30-day leads, deliver in 90 with half the batch rejected. No backups mean stockouts mid-campaign.

Procurement teams tell us they waste weeks vetting. Chinese mills claim "FDA compliant" without proof. Third-party audits? Rare. Risk multiplies for cross-border deals.

• Moisture ingress cracks coatings en route.
• Viscosity mismatches cause spraying issues.
• Unstable particle sizes clog coaters.
• Missing phthalate-free certs block US clearance.

One Midwest supplement buyer shared: "Lost $50k on a bad enteric batch. Now we stick to proven partners." Smart move.

Enteric pills demand precision. Stomach pH 1.2-3 holds for 2 hours. Intestine hits 6.8 – coating must rupture clean. Get it wrong, bioavailability tanks. Patients complain. Returns spike.

Our Enteric Pill Solution – HPMC-Based, Proven Release Profiles

At Tang Zhi, we specialize in hypromellose enteric coatings. Not generic powder – tailored grades for tablets, capsules, pellets. Our HPMC E5/E15 viscosities form robust 5-12% weight gain films. Disintegration starts at pH 5.5, full release by 6.8.

We've run thousands of OEM batches. Custom enteric pills for probiotics, enzymes, bisphosphonates. Phthalate-free, vegan compliant. Mix with our RDP-VAE for flexibility if needed.

Process insight: Spray-dry aqueous dispersions on perforated pans. 35-45°C inlet air prevents tackiness. We've dialed in 95% yield rates through automated controls.

Buyers appreciate the stability. Our coatings hold through 40°C/75% RH for 6 months. No migration to cores. USP <711> compliant dissolution.

For wholesale, minimum 500kg runs. Scale to tons. Private label your enteric omeprazole or multivitamins.

Testing? We provide in-house HPLC for drug release curves. Third-party labs on request – SGS, Eurofins.

One tweak we've seen save time: Grade K4M for thicker coatings on large caplets. Dissolves uniform, even oversized.
