Buy Parlodel (Bromocriptine 2.5mg) Online - Serum Pharmaceuticals Original Sandoz Brand Dopamine Agonist

Parlodel (Bromocriptine Mesylate 2.5 mg) represents the foundational first-generation ergot-derived dopamine agonist - the reference dopamine receptor agonist established over 45 years for hyperprolactinemia treatment, prolactinoma management, comprehensive fertility restoration, lactation suppression, Parkinson disease therapy, and acromegaly management. Originally developed by Sandoz Pharmaceuticals (now Novartis following the 1996 merger with Ciba-Geigy) and FDA-approved as Parlodel in 1978 for hyperprolactinemia and other prolactin-related disorders, bromocriptine established the pharmacological approach to dopamine agonist therapy across multiple therapeutic areas. Parlodel on rxshop.md is manufactured by Serum Pharmaceuticals - established Indian pharmaceutical manufacturer with quality standards and reproductive medicine focus.
Bromocriptine works as a non-selective ergot-derived dopamine agonist providing potent dopamine D2 and moderate D1 receptor agonism. First, bromocriptine binds pituitary lactotroph dopamine D2 receptors mimicking natural dopamine inhibition of prolactin. Second, this suppresses prolactin secretion normalizing elevated prolactin levels. Third, bromocriptine induces prolactinoma cell size reduction and progressive tumor shrinkage over weeks to months of therapy. Fourth, normalized prolactin restores hypothalamic-pituitary-gonadal axis function re-establishing normal reproductive hormone patterns. Fifth, bromocriptine provides additional therapeutic effects in Parkinson disease (dopamine replacement) and acromegaly (paradoxical growth hormone suppression).
Parlodel addresses comprehensive dopamine-related indications. Primary uses include hyperprolactinemic disorders from idiopathic causes or prolactinomas, amenorrhea from elevated prolactin, galactorrhea, infertility from hyperprolactinemia, lactation suppression (postpartum where clinically indicated), Parkinson disease as adjunct or alternative therapy, and acromegaly for growth hormone reduction. Bromocriptine remains widely used first-line therapy in many settings due to established efficacy, extensive safety data over 45 years, particular safety experience during pregnancy for prolactinoma continuation, and cost-effectiveness.
Parlodel is available in four pack sizes at the 2.5 mg strength - 30, 60, 90, and 120 tablets. The 60-tablet pack is the bestseller reflecting typical monthly to bi-monthly supply for continuous therapy. Standard dosing initiates at 1.25 mg (half tablet) at bedtime to minimize orthostatic hypotension and nausea, escalating gradually to standard maintenance of 2.5-15 mg daily in divided doses. Contraindicated in uncontrolled hypertension, cardiac valvular disease, fibrotic disorders history, and ergot alkaloid hypersensitivity. Requires endocrinology or neurology specialist supervision.

💊 Introduction to Parlodel
Parlodel is a prescription oral medication containing bromocriptine mesylate 2.5 mg as its active ingredient in tablet form. Bromocriptine is a first-generation ergot-derived dopamine receptor agonist - a class of medications that mimic natural dopamine action at target receptors throughout the body. Bromocriptine was originally developed by Sandoz Pharmaceuticals in Switzerland and received FDA approval as Parlodel in 1978 for hyperprolactinemia and related disorders - establishing over 45 years of continuous clinical use as reference dopamine agonist therapy worldwide. Sandoz merged with Ciba-Geigy in 1996 forming Novartis Pharmaceuticals which maintains original brand rights internationally.
The Parlodel brand available on rxshop.md is manufactured by Serum Pharmaceuticals - established Indian pharmaceutical manufacturer with generic portfolio focused on reproductive medicine, endocrinology, and neurology products. Serum Pharmaceuticals produces bioequivalent generic bromocriptine under quality manufacturing standards providing cost-effective access to this important dopamine agonist therapy.
Bromocriptine occupies the historical foundational position as the first ergot-derived dopamine agonist FDA-approved for hyperprolactinemia and remains widely used clinical therapy despite emergence of newer selective dopamine agonists. Advantages include over 45 years of extensive clinical experience, substantial pregnancy safety data supporting continuation during pregnancy when needed (particularly for prolactinoma patients), broad multi-indication utility spanning endocrinology and neurology, and cost-effectiveness compared to newer selective agents. The Endocrine Society clinical guidelines position bromocriptine and cabergoline as first-line hyperprolactinemia therapy with cabergoline generally preferred for efficacy and dosing convenience, but bromocriptine remains preferred when pregnancy is planned or desired due to accumulated safety data.
Parlodel serves comprehensive dopamine-related indications across multiple therapeutic areas. Primary uses include hyperprolactinemic disorders from idiopathic causes or prolactinomas, amenorrhea from elevated prolactin, galactorrhea, infertility from hyperprolactinemia, lactation suppression (postpartum where clinically indicated), Parkinson disease as adjunct or alternative therapy, and acromegaly for growth hormone reduction. Bromocriptine demonstrates prolactin normalization in majority of hyperprolactinemic patients and substantial prolactinoma tumor size reduction over weeks to months of continuous therapy.
Parlodel is available on rxshop.md in four pack sizes at the 2.5 mg strength - 30, 60, 90, and 120 tablets. The 60-tablet pack is the bestseller reflecting typical monthly to bi-monthly supply for continuous therapy. Standard dosing requires careful gradual titration starting at 1.25 mg (half tablet) at bedtime to minimize orthostatic hypotension and nausea, escalating slowly to standard maintenance dose (2.5-15 mg daily for hyperprolactinemia, up to 30-40 mg daily for Parkinson disease). This gradual titration is essential for tolerability.

🧪 Chemistry of Bromocriptine
Chemical Structure
Bromocriptine mesylate has the chemical formula C32H40BrN5O5·CH4O3S with molecular weight approximately 750.7 g/mol. Chemically, bromocriptine is 2-bromo-alpha-ergocryptine mesylate - a semi-synthetic ergot alkaloid derivative created by 2-bromination of natural ergocryptine. The mesylate salt formulation provides improved solubility and oral bioavailability compared to the free base form.
Structural Features
Bromocriptine structural features:
- Ergoline core structure - characteristic tetracyclic ergot alkaloid backbone
- 2-bromination modification - key structural feature providing dopamine agonist activity
- Peptide side chain - cyclic tripeptide portion of ergocryptine structure
- Complex stereochemistry - multiple chiral centers
- Mesylate salt form - enhanced solubility and bioavailability
- Ergot alkaloid class - shared structural features with other ergot compounds
- Semi-synthetic derivative - modified natural ergocryptine backbone
🔬 Mechanism of Action
Dopamine Receptor Interactions
Bromocriptine dopamine receptor activity:
- D2 dopamine receptor: Primary target - full agonist activity
- D1 dopamine receptor: Partial agonist to weak antagonist activity
- D3 dopamine receptor: Full agonist activity
- Serotonin 5-HT2A receptor: Partial agonist (contributes to fibrotic concerns)
- Alpha-adrenergic receptors: Weak activity contributing to orthostatic effects
- Non-selective profile: Multiple receptor activities vs cabergoline high D2 selectivity
Pituitary Prolactin Suppression
Bromocriptine mechanism in hyperprolactinemia:
- Pituitary lactotroph D2 receptor binding: Bromocriptine binds D2 receptors on pituitary lactotroph cells
- Mimics dopamine inhibition: Acts like natural hypothalamic dopamine which normally inhibits prolactin secretion
- Direct prolactin suppression: Immediate suppression of prolactin secretion from lactotroph cells
- Prolactinoma cell effect: Direct suppression of prolactinoma tumor cells
- Progressive tumor shrinkage: Weeks to months of tumor size reduction from cell size reduction and apoptosis
- Restored HPG axis function: Prolactin normalization restores hypothalamic-pituitary-gonadal axis
- Return of ovulation: Restored reproductive hormone patterns enable ovulation and menstruation
Parkinson Disease Mechanism
In Parkinson disease, bromocriptine acts as dopamine agonist at nigrostriatal dopamine receptors compensating for the loss of dopaminergic neurons. Bromocriptine binds post-synaptic D2 receptors in striatum mimicking endogenous dopamine signaling. This reduces the motor symptoms of bradykinesia, rigidity, and tremor. Bromocriptine can be used as monotherapy in early Parkinson disease or as adjunct to levodopa in more advanced disease. Newer non-ergot dopamine agonists (pramipexole, ropinirole) have largely replaced bromocriptine for Parkinson disease due to safety concerns with ergot-derived agents.
Acromegaly Paradoxical Effect
In acromegaly (growth hormone excess disorder), bromocriptine paradoxically suppresses growth hormone (GH) secretion despite being dopamine agonist. Normal individuals show GH increase with dopamine agonism, but acromegaly patients demonstrate paradoxical GH suppression. Approximately 20-30 percent of acromegaly patients respond to bromocriptine monotherapy with adequate GH control. Higher doses (30-40 mg daily) typically needed for acromegaly indication. Modern therapy typically uses somatostatin analogs first-line.
🔬 Pharmacokinetic Profile
| Parameter | Value | Clinical Significance |
|---|---|---|
| Oral bioavailability | Approximately 6 percent | Low but consistent - extensive first-pass metabolism |
| Food effect | Increases absorption | Take with food to improve absorption and reduce nausea |
| Time to peak (Tmax) | 1-3 hours | Rapid onset of clinical effect |
| Half-life | 3-6 hours (biphasic) | Short half-life requires multiple daily dosing |
| Onset of prolactin suppression | Within hours | Rapid clinical effect |
| Duration of prolactin effect | 8-12 hours per dose | Supports 2-3 times daily dosing |
| Protein binding | Approximately 90-96 percent | Highly protein bound |
| Metabolism | Hepatic CYP3A4 | Extensive first-pass metabolism |
| Elimination | Biliary (primarily) | Approximately 90 percent fecal excretion |
| Tumor response timeline | Weeks to months | Progressive prolactinoma shrinkage |
🧠 Understanding Hyperprolactinemia
Normal Prolactin Physiology
Prolactin physiology overview:
- Produced by pituitary lactotroph cells
- Uniquely regulated by dopamine INHIBITION (unlike other pituitary hormones stimulated by hypothalamic factors)
- Normal blood levels: Under 25 ng/mL in women, under 20 ng/mL in men
- Physiological elevations: Pregnancy, lactation, stress, sleep, exercise
- Primary function: Lactation initiation and maintenance after childbirth
- Additional roles: Reproductive function, immune modulation, osmoregulation
- Feedback: Elevated prolactin suppresses GnRH and downstream reproductive hormones
Causes of Hyperprolactinemia
- Prolactinoma: Prolactin-secreting pituitary adenomas (most common pathological cause)
- Idiopathic hyperprolactinemia: Unknown etiology with normal MRI imaging
- Drug-induced: Antipsychotics (typical/atypical), metoclopramide, opioids, antidepressants
- Primary hypothyroidism: Elevated TRH stimulates prolactin secretion
- Chronic renal failure: Reduced prolactin clearance elevates levels
- Hypothalamic disorders: Stalk compression, hypothalamic tumors
- Chest wall stimulation: Trauma, herpes zoster, chest wall surgery
- PCOS: Mild hyperprolactinemia sometimes associated
Clinical Manifestations
In women, hyperprolactinemia causes amenorrhea, oligomenorrhea, galactorrhea, infertility, decreased libido, vaginal dryness, and osteoporosis from prolonged hypoestrogenism. In men, hyperprolactinemia causes decreased libido, erectile dysfunction, infertility from oligospermia, and rarely galactorrhea or gynecomastia. Macroprolactinomas can cause mass effect symptoms including headache, visual field defects (bitemporal hemianopsia from optic chiasm compression), cranial nerve palsies, and panhypopituitarism.
🎯 Approved Endocrine Indications
- Hyperprolactinemia (All Causes)
- Primary FDA indication for elevated blood prolactin levels from any cause including idiopathic hyperprolactinemia, drug-induced, and other secondary causes. Standard dosing: Start 1.25 mg at bedtime, escalate to 2.5-15 mg daily divided doses to normalize prolactin.
- Microprolactinoma
- Prolactin-secreting pituitary microadenomas under 10 mm requiring medical suppression. Medical therapy first-line for majority of patients over surgical intervention. Standard dosing: 2.5-7.5 mg daily in divided doses.
- Macroprolactinoma
- Large prolactin-secreting pituitary adenomas over 10 mm requiring both prolactin normalization and tumor shrinkage. Medical therapy first-line even for large tumors given effective response. Standard dosing: 5-15 mg daily divided doses, higher for aggressive tumors.
- Galactorrhea
- Inappropriate milk production in non-pregnant non-lactating women or men from prolactin elevation. Requires diagnostic workup for underlying causes. Standard dosing: 2.5-7.5 mg daily divided doses.
- Hyperprolactinemic Amenorrhea and Infertility
- Amenorrhea and infertility caused by prolactin-related HPG axis suppression. Prolactin normalization restores ovulation and fertility in majority of patients. Standard dosing: 2.5-7.5 mg daily divided doses until pregnancy achieved.
- Postpartum Lactation Suppression
- Suppression of postpartum milk production where medically indicated. Not FDA approved for this indication in US but used in many countries. Standard dosing: 2.5 mg twice daily for 14 days postpartum.

- Category B classification with substantial safety data. Standard practice discontinue when pregnancy confirmed. Continuation for macroprolactinoma requires endocrinology guidance.
- Male Patients
- Effective for male hyperprolactinemia restoring testosterone, sexual function, and fertility. Prolactinoma treatment identical to women. Enhanced impulse control disorder monitoring.
- Prolactinoma Patients
- First-line therapy for both microadenomas and macroadenomas. Regular pituitary MRI monitoring recommended. Long-term therapy typically required with periodic assessment.
- Elderly Patients
- More sensitive to side effects particularly postural hypotension. Enhanced titration caution starting lower doses. Cardiovascular assessment important. Fall risk considerations.
- Parkinson Disease Patients
- Higher doses required (up to 30-40 mg daily). Enhanced cardiac and fibrotic monitoring. Non-ergot dopamine agonists typically preferred in modern practice.
- Cardiovascular Disease Patients
- Enhanced monitoring for orthostatic hypotension. Contraindicated in severe ischemic heart disease or peripheral vascular disease. Baseline cardiovascular assessment essential.
- Cardiac Valve Disease History
- Contraindicated. Ergot-derived dopamine agonists carry cardiac valve fibrosis risk. Baseline and periodic echocardiogram monitoring required.
- Fibrotic Disorder History
- Contraindicated. Ergot class carries pulmonary, retroperitoneal, and pericardial fibrosis risk. Alternative therapies preferred.
- Depression or Psychiatric History
- Rare psychiatric adverse effects possible. Monitor mood carefully. Enhanced impulse control disorder screening. Coordinate with mental health providers.
- Hepatic Impairment
- Reduced dose may be needed due to hepatic metabolism. Monitor liver function periodically.

Important Medical Disclaimer: This medication guide provides general information about Parlodel (Serum Pharmaceuticals generic bromocriptine mesylate 2.5 mg tablets) and does not constitute individualized medical advice. Every patient situation is unique and requires evaluation by an endocrinologist, gynecologist, neurologist, or qualified healthcare provider before starting dopamine agonist therapy. Parlodel requires comprehensive workup to establish hyperprolactinemia cause including pituitary MRI, thyroid function testing, medication review, pregnancy testing, and cardiovascular assessment before initiation. Long-term therapy requires periodic prolactin monitoring, dose adjustments, and echocardiogram surveillance. Prolactinoma patients require regular pituitary MRI monitoring. CRITICAL SAFETY: Ergot-derived dopamine agonists including bromocriptine carry cardiac valve fibrosis risk requiring baseline and periodic echocardiogram monitoring during long-term therapy. Fibrotic complications including pulmonary, pericardial, and retroperitoneal fibrosis are rare but serious adverse events. Contraindicated in cardiac valvular disease, fibrotic disorders history (pulmonary, pericardial, retroperitoneal), uncontrolled hypertension, ergot alkaloid hypersensitivity, and pregnancy-related hypertensive disorders history. Dopamine agonist class carries impulse control disorder risk (pathological gambling, hypersexuality, compulsive behaviors) requiring patient and family awareness. CRITICAL titration protocol essential to minimize nausea and orthostatic hypotension - start 1.25 mg at bedtime, escalate every 3-7 days, take with food. Bromocriptine remains preferred dopamine agonist when pregnancy is planned due to extensive safety data. Postpartum use for lactation suppression rarely causes serious cardiovascular events - avoid in women with cardiovascular risk factors. Report cardiovascular symptoms, breathing difficulties, impulse control changes, severe postural hypotension, or psychiatric symptoms immediately. Not compatible with breastfeeding due to lactation suppression. Long-term therapy requires periodic reassessment. If you experience concerning symptoms contact your healthcare provider promptly. The information provided here should complement but never replace direct professional medical guidance from your endocrinologist or neurologist.
