Ropinirole Production Cost Reports

The report provides a detailed analysis essential for establishing a Ropinirole production plant. It encompasses all critical aspects necessary for Ropinirole production, including the cost of Ropinirole production, Ropinirole plant cost, Ropinirole production costs, and the overall Ropinirole production plant cost. Additionally, the study covers specific expenditures associated with setting up and operating a Ropinirole production plant. These encompass production processes, raw material requirements, utility requirements, infrastructure needs, machinery and technology requirements, manpower requirements, packaging requirements, transportation requirements, and more.

Ropinirole is a non-ergoline dopamine agonist that is used for managing Parkinson's disease symptoms. It is used to manage tremors, rigidity, bradykinesia, and motor fluctuations. It works as initial monotherapy or adjunctive therapy with levodopa to enhance on-time and reduce dyskinesias in advanced stages. It is also used for moderate-to-severe primary restless legs syndrome (RLS) by relieving sensory discomfort and periodic limb movements that disrupt sleep.

It exerts its effects through high-affinity binding to D2 and D3 dopamine receptors, mimicking endogenous dopamine to stimulate nigrostriatal pathways without the fibrotic or valvular risks of ergot-derived agonists. It is also used in SSRI-induced akathisia or Parkinsonism, nocturnal PD symptoms, fibromyalgia-related pain, and certain sleep disorders.

The market for Ropinirole is driven by growing cases of Parkinson's disease and restless legs syndrome. The aging global populations and improved neurological disorder diagnostics and awareness contribute to its market growth. The expanded healthcare access in developing markets and innovations in extended-release formulations that boost patient adherence and outcomes fuel its market.

Also, supportive reimbursement policies and rising demand for non-ergoline dopamine agonists free from fibrotic risks associated with older therapies make it a popular product. The industrial Ropinirole procurement is influenced by long-established generic competition following early patent expirations. The cost-effective sourcing from certified manufacturers, GMP compliance, Drug Master File availability, and reliable supply chains further impact its sourcing strategies.

Raw Material for Ropinirole Production

According to the Ropinirole production plant project report, the key raw materials used in the production of Ropinirole include 4-(2-Bromoethyl)-1,3-Dihydro-2H-Indol-2-one, n-Propylamine, and Acetonitrile.

Production Process of Ropinirole

The extensive Ropinirole production cost report consists of the following major industrial production process:

1. By Nucleophilic Substitution: The production process for Ropinirole involves a nucleophilic substitution. In this process,  4-(2-bromoethyl)-1,3-dihydro-2H-indol-2-one reacts with n-propylamine to give 4-[2-(propylamino)ethyl]-1,3-dihydro-2H-indol-2-one (ropinirole free base). The mixture is cooled, poured into 1N hydrochloric acid, and extracted with ether to remove the vinyl byproduct. This is then basified to pH 7-7.5 with sodium bicarbonate and extracted with dichloromethane. The organic layer is dried, evaporated, and the free base is dissolved in absolute ethanol, saturated with HCl gas, and recrystallized to give pure Ropinirole hydrochloride salt as the final product.

Ropinirole is a white to pale yellow crystalline dopamine agonist with the free base molecular formula of C16H24N2O and molecular weight 260.38 g/mol. It has a logP value of about 2.7, pKa around 7.8, and a predicted boiling point near 410 degree Celsius at standard pressure. The ropinirole hydrochloride salt has formula C16H25ClN2O and a molecular weight of 296.84 g/mol. It appears as a white to off white solid with a melting point in the range 241-250 degree Celsius. It shows high aqueous solubility on the order of hundreds of milligrams per millilitre. It is readily soluble in methanol and acetonitrile but only slightly soluble in ethanol, with linear pharmacokinetics and an elimination half life of roughly six hours.
