Introduction: Pentazocine's Clinical Role
Pentazocine is a mixed agonist-antagonist opioid analgesic developed for moderate to severe pain. Its kappa-receptor agonism delivers reliable analgesia in obstetric, orthopedic, post-operative, and trauma settings, while its weaker mu-receptor activity gives it a lower dependence and respiratory depression profile than morphine. In many emerging and lower-middle-income markets, Pentazocine remains a workhorse parenteral analgesic — particularly where stricter Schedule II opioids face supply or regulatory restrictions.
Manufacturing Pentazocine Injection at hospital and export scale is not a routine sterile fill-finish project. It is a controlled substance, which means the API itself, the bulk solution, the partially filled containers, and the finished goods all sit under a strict chain of custody from the moment they enter the building until shipment release. Farbe Firma Pvt Ltd, in Ankleshwar, Gujarat, India, operates this product line under WHO-GMP conditions with the documentation discipline that controlled-substance compliance demands.
Farbe Firma's Pentazocine Injection Portfolio
Farbe Firma manufactures Pentazocine Lactate Injection in the strength most prescribed clinically — 30mg/ml — and in the ampoule sizes that hospitals and tender procurement teams use day to day: 1ml ampoules (single dose) and 2ml ampoules (60mg adult dose). Each ampoule is filled in a Grade A LAF zone inside an ISO Class 5 cleanroom, sealed using OPC (one-point-cut) or color-break technology for nurse safety, and packed into tamper-evident secondary cartons with patient information inserts in multiple languages.
Controlled Substance Compliance
Pentazocine is governed by India's Narcotic Drugs and Psychotropic Substances Act (NDPS Act) and by international conventions on psychotropic substances. Farbe Firma's plant maintains a dedicated controlled-substance vault, segregated weighing and compounding suites, dual-key access logs, real-time CCTV with two-year retention, and reconciled daily inventory records. Every kilogram of API received is matched against an issued kilogram of finished goods at QA reconciliation, with documented yield variances signed by both Production Head and QA Head.
On the export side, Farbe Firma's regulatory affairs cell coordinates with India's Narcotics Control Bureau (NCB) and the destination country's competent authority for every shipment — including export authorization, import permit verification, customs documentation, and post-shipment reconciliation. This level of compliance discipline is what enables buyers in tightly regulated markets to register and reorder Pentazocine without operational risk.

Quality, Stability, and Export Support
Every batch of Pentazocine Injection is released only after full sterility testing (USP <71>), bacterial endotoxin testing (LAL per USP <85>), pH and osmolality verification, assay by validated HPLC against USP reference standards, related substances profiling, and ampoule integrity testing. We use USP-grade Pentazocine Lactate API from approved manufacturers with DMF backing, and we maintain redundancy across two qualified API sources to insulate buyers from supply disruption.
Our stability program for Pentazocine Injection covers both ICH Zone IVa (hot, dry) and Zone IVb (hot, humid) conditions, with a 24 month established shelf life. We provide full stability data packages, validated method transfer documents, and Drug Master File extracts to support buyer-side registration. CTD and ACTD dossiers are prepared in-house, and we routinely support tender submissions to Ministries of Health across Africa, CIS, Latin America, the Middle East, and South-East Asia.
