Codeine Base is a naturally occurring phenanthrene opioid alkaloid and a fundamental Active Pharmaceutical Ingredient (API) in the pharmaceutical industry. Manufactured by Parand Darou Co. in strict compliance with international compendial standards (BP and USP), this high-purity base serves as an essential precursor for the synthesis of various codeine salts and the formulation of finished dosage forms, primarily indicated as analgesics and antitussives.
Mechanism of Action & Clinical Indications
Codeine acts as a selective agonist at μ-opioid receptors. Its primary analgesic efficacy is achieved through its hepatic bioactivation into morphine via the cytochrome P450 enzyme CYP2D6. In addition to its moderate pain-relieving properties, codeine exerts a direct centrally-acting inhibitory effect on the medullary cough center, making it a benchmark therapeutic agent for the suppression of persistent, non-productive chronic coughs.
Quality Attributes, Purity & Storage
Parand Darou supplies Codeine Base as colorless crystals or a white crystalline powder with a verified purity profile of no less than 98.5% and an assay range of 98.5% to 100.5% (calculated on the anhydrous basis). The substance exhibits a defined melting range of 155–159 °C, with water content controlled at a maximum of 6.0%. It maintains pharmaceutical stability for at least 2 years under controlled room temperature when stored in airtight, light-resistant packaging.
