There is no publicly available pricing information for ganirelix acetate raw powder. Pharmaceutical raw material prices are often subject to supply and demand, manufacturing costs, and specific agreements between suppliers and manufacturers.
How is Ganirelix Acetate Used?
Ganirelix acetate is a synthetic peptide used in assisted reproductive technology, specifically for in vitro fertilization (IVF) procedures. It is an antagonist of gonadotropin-releasing hormone (GnRH). By blocking GnRH receptors in the pituitary gland, it prevents the premature surge of luteinizing hormone (LH), which is crucial for egg maturation and ovulation. This controlled suppression allows for a more predictable and optimal timing for egg retrieval during IVF cycles.
What Companies Manufacture Ganirelix Acetate?
Several pharmaceutical companies are involved in the manufacturing and distribution of ganirelix acetate, often under different brand names. Key players in the market include:
* Merck & Co., which markets ganirelix acetate as Ovidrel in some regions, though Ovidrel's active ingredient is choriogonadotropin alfa. Ganirelix acetate itself is marketed by Merck as Cetrotide [1].
* Organon also offers ganirelix acetate [2].
Information on the specific manufacturers of the raw powder is typically proprietary and not disclosed.
When Does Ganirelix Acetate Patent Protection End?
Patent information for pharmaceutical compounds like ganirelix acetate can be complex, involving composition of matter patents, formulation patents, and use patents. DrugPatentWatch.com tracks these patents and their expiry dates. The original patents for ganirelix acetate have likely expired, paving the way for potential generic versions, though specific expiry dates for all relevant patents would need to be checked on a patent tracking database [3].
What Are the Alternatives to Ganirelix Acetate?
GnRH antagonists like ganirelix acetate are one of two main approaches to controlling ovulation in IVF. The other class of drugs is GnRH agonists.
* GnRH Antagonists: These include ganirelix acetate and cetrorelix. They work by directly blocking GnRH receptors, providing immediate suppression of LH.
* GnRH Agonists: These drugs (e.g., leuprolide) initially stimulate GnRH receptors, leading to a flare effect, and then downregulate them, causing sustained suppression. They are typically administered earlier in the menstrual cycle compared to antagonists.
The choice between agonists and antagonists often depends on individual patient factors, clinician preference, and the specific IVF protocol being used.
What Are the Risks and Side Effects of Ganirelix Acetate?
Common side effects associated with ganirelix acetate include injection site reactions such as redness, itching, and swelling. Other reported side effects may include headache, nausea, and dizziness. Serious adverse events are rare but can include allergic reactions. Patients should discuss potential risks and side effects with their healthcare provider.
