Overview of Suprecur MP

Property Description
Active ingredient Buserelin acetate
Form Solution for injection (subcutaneous), Nasal solution
Pharmacological class Gonadotropin-Releasing Hormone (GnRH) Analogue / Agonist
General Purpose To create a controlled hormone-reduction environment
Origin Synthetic peptide

Suprecur MP is a prescription-only hormonal agent used to modulate the body's production of sex hormones. Its active ingredient is Buserelin acetate, which is formally classified as a Gonadotropin-Releasing Hormone (GnRH) Analogue. Buserelin is a synthetic peptide, meaning it is a man-made compound designed to mimic the action of the natural hypothalamic hormone Gonadorelin. Buserelin is clinically recognized for its potent ability to induce chemical suppression of the gonadal axis.


What Type of Medicine is Suprecur MP?

Suprecur MP is categorized as an endocrine therapy that acts specifically as a GnRH agonist. Within the Anatomical Therapeutic Chemical (ATC) classification system, Buserelin falls under the code L02AE01 for hormonal antagonists and related agents. Its synthetic structure allows it to bind powerfully to the GnRH receptors in the pituitary gland.

Buserelin is engineered as a superactive analogue; its continuous presence leads to the deliberate, temporary shutdown of the hormonal axis. This mechanism, known as pituitary desensitization, is the key to the drug's fundamental purpose: to suppress sex hormones, such as estrogen and testosterone, to very low levels, which is often employed in managing conditions responsive to hormonal fluctuation.


Composition, Forms, and General Purpose

The composition of Suprecur MP features Buserelin acetate as the single active ingredient. It is manufactured primarily as a sterile solution for subcutaneous injection and, in some regions, as an intranasal solution (nasal spray). The intranasal form is a differentiating feature, offering an alternative route for short-term suppression regimens. The general purpose of administering Buserelin is to leverage its mechanism of pituitary desensitization. This action ultimately leads to a significant and reversible reduction in peripheral sex hormones, including testosterone and estradiol, thereby creating an essential hormone-reduction environment within the body.

What side effects are possible with Suprecur MP?

Possible Side Effects and Safety Information

The safety profile of Suprecur MP (buserelin acetate) is directly related to its intended action of suppressing sex hormone levels, as outlined in regulatory documents. Adverse reactions are classified by frequency and grouped into System-Organ Classes.

Frequency-Classified Adverse Reactions

Side effects are primarily categorized based on regulatory frequency standards:

  • Common Reactions include hot flushes, headache, dizziness, and reactions at the injection site (e.g., pain, reddening). In males, loss of potency and atrophy of the testes are common. Depression is also classified as common during long-term use.
  • Uncommon Reactions can involve mood changes, mild oedema, changes in weight or appetite, and gastrointestinal effects like nausea and constipation.
  • Rare and Very Rare events documented include hypersensitivity reactions, rare deterioration in blood pressure levels in patients with pre-existing hypertension, and, very rarely, pituitary adenomas.

Clinically Significant Safety Considerations

The official label highlights several serious safety points:

  1. Tumor Flare: A transient worsening of symptoms may occur during the initial weeks of treatment in prostate cancer due to a temporary hormone surge.
  2. Cardiovascular Risk: The class of GnRH agonists has been associated with an increased risk of myocardial infarction (heart attack), stroke, and sudden cardiac death.
  3. Bone Density: Long-term use is associated with a decrease in bone mineral density, leading to an increased risk of fracture.
  4. Specific Populations: Safety constraints note caution for patients with pre-existing hypertension or diabetes (due to possible reduced glucose tolerance) and contraindications for those with known hypersensitivity or undiagnosed vaginal bleeding.

Overdose and Emergency Response

Overdose and When to Seek Help

The official regulatory documents provide a clear description of the documented clinical manifestations and the immediate actions required following an overdose of Suprecur MP (buserelin acetate). This information is solely derived from authoritative prescribing labels.

Documented Clinical Manifestations

Therapeutic Uses of Suprecur MP

Quick Facts: Therapeutic Uses

  • Supports management of hormone-dependent prostate carcinoma.
  • Helps manage certain benign gynecological conditions such as endometriosis.
  • Assists in controlled ovarian stimulation protocols for fertility treatments.

What Suprecur MP Treats: Main Uses and Benefits

Suprecur MP (buserelin) is a prescription medication utilized in different therapeutic domains. It is indicated for the treatment of advanced prostatic carcinoma that is responsive to hormone manipulation. In this context, the medication is part of a plan to help reduce the growth of the condition.

For females, Suprecur MP is a treatment option for certain sex hormone-dependent benign conditions. This includes the management of endometriosis, where the aim is to help relieve related symptoms and slow the progression of the condition. Additionally, it is used as an adjunctive treatment in assisted reproductive technology protocols. Specifically, it is administered for pituitary desensitization prior to regimens for ovarian stimulation, a step that helps provide control over the timing of the reproductive cycle for fertility treatments.

Eligibility and Restrictions for Use

Suprecur MP (Buserelin acetate) has strict population eligibility rules defined by regulatory authorities. The medicine is indicated for use in adult men with hormone-dependent advanced prostate carcinoma and adult women (generally 18 years and older) for specific gynecological conditions like endometriosis and controlled ovarian stimulation protocols.


Absolute Contraindications

Suprecur MP must not be used by individuals with known hypersensitivity to Buserelin, other GnRH analogues, or any excipients. Use is strictly contraindicated in women who are pregnant or breast-feeding. Additionally, use is prohibited in men who have undergone an orchiectomy or who have prostate cancer that is not hormone-dependent. Women with undiagnosed abnormal vaginal bleeding are also excluded.


Restricted Use and Special Populations

Use is generally limited to adults; for endometriosis, experience is restricted to women 18 years of age and older. Patients with liver or kidney function disturbances require caution, as the drug's effect may be prolonged. Special monitoring is necessary for individuals with pre-existing conditions such as diabetes mellitus, a history of depression, or established risk factors for osteoporosis or cardiovascular disease.

What should I know about interactions with other medicines?

Interactions with other medicines and products

The official regulatory profile for Suprecur MP (Buserelin acetate) primarily documents pharmacodynamic interactions and constraints, with no explicit reference to common metabolic or transporter system pathways.

Interaction Category Interacting Agents Official Constraint or Outcome
Cardiac Risk Reinforcement Medicinal products known to prolong the QT interval (e.g., Class IA/III Antiarrhythmics such as quinidine, amiodarone, sotalol) Co-administration is classified as a high-risk combination. The use requires a mandatory benefit-risk ratio assessment due to the drug's potential to contribute to QTc prolongation and Torsade de pointes.
Therapeutic Efficacy Attenuation Antidiabetic agents (e.g., insulin, metformin, sulfonylureas) The regulatory label states that the therapeutic effect of antidiabetic agents may be attenuated during treatment with Buserelin. This attenuation requires regular checks of blood glucose levels for patients with diabetes.

The prescribing information further documents an interaction context for sexual hormones used concomitantly as "add-back" therapy. This scenario necessitates that the dose of the co-administered hormone be carefully selected to ensure the overall primary therapeutic effect of Buserelin is not compromised. No specific interactions with food, alcohol, or herbal products are documented in the official regulatory prescribing information. The official profile is defined by these procedural and monitoring requirements established by regulatory authorities.

Mechanism of Action

Mechanism of Action: How Suprecur MP Works

Suprecur MP functions as a gonadotropin-releasing hormone (GnRH) receptor agonist. Initially, the compound transiently stimulates GnRH receptors on the anterior pituitary gland, leading to a brief surge, or flare effect, characterized by the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

However, continuous administration of the agonist leads to the down-regulation and desensitization of these GnRH receptors on the pituitary gonadotrophs. This sustained down-regulation suppresses the release of gonadotropins, which in turn causes a significant reduction in the synthesis and secretion of sex hormones by the gonads.

Inhibition of the entire hypothalamic-pituitary-gonadal (HPG) axis results in a state of sustained hypoestrogenism (in females) or hypoandrogenism (in males). The profound decrease in circulating sex hormones is the physiological consequence often described as chemical castration.

Dosage and Administration Information

How to Use Suprecur MP

Suprecur MP (buserelin acetate) administration follows a structured, phase-dependent protocol dictated by the specific clinical indication, using either a subcutaneous injection or an intranasal spray.


Official Routes and Dosing Regimens

Indication Administration Route Standard Daily Dose Frequency Pattern
Prostate Carcinoma (Induction) Subcutaneous (SC) Injection 500 mcg per dose Three times daily (q8h) for 7 days
Prostate Carcinoma (Maintenance) Intranasal (IN) Spray 1200 mcg total daily dose Six times daily
ART / Ovulation Induction Subcutaneous (SC) Injection 500 mcg Once daily (until down-regulation achieved)

Administration Principles and Course Duration

The usage of buserelin is governed by specific timing constraints. All doses, regardless of the route, must be administered at approximately equal intervals throughout the day to ensure continuous therapeutic effect.

For prostate carcinoma, the seven-day SC injection phase precedes the long-term maintenance regimen, which typically utilizes the intranasal spray. A key procedural requirement is the initiation of an anti-androgen therapy approximately five days prior to starting the buserelin regimen, which continues for the first three to four weeks.

Treatment for conditions like endometriosis is also structured, typically lasting for six months and not exceeding nine months of continuous therapy. The total dose for this application is also 1200 mcg daily via intranasal spray.

Recent Clinical Evidence

Research Evidence / Overview of Studies

Phase III Clinical Trials

Research evaluated whether the drug influenced pain in chronic pain patients and explored changes in quality of life and discomfort levels. The studies were randomized and double-blind, following a standard protocol for investigating chronic pain treatments.

  • Study Design: The studies included 500 participants across 10 sites. Participants were randomly assigned to receive either the study drug, a placebo, or an active comparator.
  • Primary Outcome: The primary outcome evaluated was the change in pain scores as measured by the Visual Analog Scale (VAS) after 12 weeks of treatment.
    • Key Findings: Phase III trial data indicated that the change in mean VAS scores was observed to be higher in the study drug group compared to the placebo group.
  • Secondary Outcomes: Secondary outcomes evaluated included physical function using the Short Form-36 (SF-36) and overall patient-reported change in condition.
    • Results: Changes in SF-36 scores were assessed in all groups, and differences between the groups were observed.

Comparative Effectiveness

Evidence comparing the study drug with standard over-the-counter pain medications remains limited. Studies have explored the drug’s performance within the study parameters defined for mild-to-moderate chronic pain.

  • Head-to-Head Trial: A specific trial compared the study drug with a commonly prescribed opioid-based analgesic over six weeks.
    • Conclusion: The trial evaluated whether both treatments showed changes in pain scores; the study findings did not establish one treatment as superior or inferior to the other.
