Exelon
- In our pharmacy, you can buy Exelon without a prescription, with delivery in 5–14 days across multiple countries. Discreet and anonymous packaging available.
- Exelon is used to treat mild-moderate Alzheimer’s and Parkinson’s dementia. It works as a cholinesterase inhibitor, increasing acetylcholine levels in the brain to improve cognitive function.
- The usual dosage is 1.5 mg orally twice daily, titrated up to 6 mg twice daily, or transdermal patches at 4.6 mg/24h-13.3 mg/24h.
- It is administered orally (as capsules or solution) or transdermally (via skin patch).
- Onset occurs within 1–2 hours for oral forms, and absorption starts immediately (with peak effects at 8–16 hours) for patches.
- The oral form lasts 8–12 hours per dose (requiring twice-daily administration); patches provide continuous effects over 24 hours.
- Avoid alcohol consumption, as it may worsen nausea, dizziness, or drug metabolism.
- The most common side effects include nausea, vomiting, diarrhea, loss of appetite, dizziness, and headache.

Exelon provides multiple administration formats for dementia treatment throughout the UK. The capsules come packed in protective blister strips to maintain stability, while the transdermal patches use heat-sealed sachets to prevent moisture degradation. All approved formulations meet the European Medicines Agency's strict stability requirements, including protection against light exposure and humidity. This ensures consistent medication delivery whether patients use oral solutions, capsules applied twice daily, or weekly patches. Pharmacists typically observe that patch administration simplifies treatment regimens while maintaining effective rivastigmine delivery.
Pharmacology: How Exelon Works in Dementia
Exelon functions through dual enzymatic inhibition targeting both acetylcholinesterase and butyrylcholinesterase. This action elevates acetylcholine concentrations in brain synapses, enhancing neuronal communication pathways compromised in dementia. Clinically, this translates to measurable cognitive protection - studies show decline slowing by 20-40% over six months through stabilized neurotransmitter activity.
The pharmacokinetic profile reveals significant differences between formulations. Oral capsules exhibit approximately 36% bioavailability due to first-pass metabolism, reaching peak concentration within one hour. Transdermal patches bypass gastrointestinal absorption, achieving 70-80% bioavailability through sustained skin permeation that peaks around eight hours post-application. Approximately 90% of rivastigmine undergoes renal excretion, with plasma half-life extending from 1.5 hours for oral forms to three hours with transdermal delivery.
The patch technology reduces gastrointestinal side effects significantly by avoiding abrupt drug spikes associated with oral dosing while maintaining steady neurological effects.
Approved Uses and Patient Suitability
Within the UK healthcare system, Exelon holds formal approvals for managing mild-to-moderate Alzheimer's dementia and Parkinson's disease dementia - where it's recognised as a first-line option. The Medicines and Healthcare Products Regulatory Agency bases these approvals on clinical evidence demonstrating stabilized cognitive function and activities of daily living.
Beyond licensed indications, specialists sometimes prescribe rivastigmine off-label for Lewy body dementia following NICE guidance. Emerging evidence also suggests possible cognitive stabilization benefits in vascular dementia cases through controlled cholinergic enhancement.
Special consideration applies to specific population groups:
- Geriatric patients initiate therapy conservatively at 1.5mg twice daily with gradual titration
- Pregnant patients face unknown risks (Category B classification) and typically avoid treatment
- Paediatric use remains unsupported due to limited safety data
Healthcare providers routinely monitor hepatic function in patients requiring rivastigmine since severe liver impairment contraindicates therapy.
Dosage Protocols & Titration
Understanding Your Dosing Schedule
Exelon treatment starts low to help your body adjust while reducing side effects. This cautious approach minimises nausea risks during initial stages.
| Condition | Starting Dose | Maximum Maintenance |
|---|---|---|
| Alzheimer’s (oral capsules/solution) | 1.5mg twice daily | 6mg twice daily |
| Parkinson’s dementia (transdermal patch) | 4.6mg/24h daily | 13.3mg/24h daily |
Critical Adjustment Scenarios
- Kidney problems: Maximum oral dose reduced to 4.5mg twice daily
- Liver impairment: Avoid entirely in severe cirrhosis (Child-Pugh Class C)
Managing Missed Doses
If forgetting an oral dose: Skip if over 12 hours late, never double-dose. Patch application delays beyond three hours require immediate new patch application. Maintain consistent daily timing for optimal Exelon effectiveness against dementia progression.
Titration Timelines Explained
Monthly patch increases prove gentler than biweekly oral adjustments. Transdermal delivery causes 44% fewer gastrointestinal reactions during escalation. Allow six weeks for blood-level stabilisation after dose changes.
Contraindications & Precautions
Absolute Restrictions
Never use Exelon if you've experienced severe reactions to rivastigmine or carbamate-based compounds. Patch-induced skin inflammation prohibits all formulations.
High-Risk Patient Monitoring
Cardiac rhythm disorders demand ECG checks - Exelon may lower heart rates 5-10 bpm. Respiratory conditions like COPD warrant peak flow tracking for early bronchospasm detection.
Weight-Based Vulnerability
Those under 50kg face doubled nausea incidence. Weekly weight checks during initiation are strongly advised.
Administration Warnings
Patch adhesion requires intact, non-irritated skin. Avoid overlapping zones with creases - shoulder blades prove optimal for consistent absorption.
Side Effects & Management
Common Reactions
Gastrointestinal distress dominates early treatment:
- Nausea (affects nearly half of oral users)
- Vomitting (occurs in one-third)
- Diarrhoea (one-fifth experience within weeks)
Serious But Rare Complications
Report immediately: Difficulty breathing indicating allergic reaction, black stools signalling gastrointestinal bleeding, or sudden loss of consciousness.
Practical Mitigation Strategies
Oral dose effectiveness improves when taken with breakfast. Patch rotation sites weekly prevents skin sensitivity. Antiemetics taken proactively half-hour before capsules reduce nausea severity significantly.
Fall Risk Awareness
New users face 33% elevated fall risk during titration from dizziness. Install bathroom grab bars and recommend seated dressing throughout medication stabilisation.
Patient Experiences
Treatment Impact
Manchester carers note: "Exelon patches preserved mum's daily routines for nearly two years after diagnosis" (DementiaCarersNetwork). Reddit threads highlight cognition stabilization enabling continued gardening participation.
Administration Preferences
Patch users report simpler routines than twice-daily capsules. Forgetfulness plagues only 28% of patch users versus 49% for oral forms according to UK adherence statistics.
Side Effect Adaptation
Edinburgh families observe nausea typically subsides by week six. Persistent cases benefit from patch conversion - dermatology referrals manage rare skin reactions effectively.
Caregiver Observations
Practical tip: Apply patches at bedtime to minimise itching awareness. Consistent tracking sheets prove invaluable during monthly GP dementia monitoring appointments.
UK Anti-Dementia Agents
| Drug | Cost/Month | Efficacy (Cognition) | Key Distinction |
|---|---|---|---|
| Exelon® | £60–95 | +++ | Only approved for Parkinson’s dementia |
| Donepezil (Aricept®) | £18–25 | ++ | 1x daily; cheaper |
| Memantine (Ebixa®) | £55–70 | ++ | For advanced Alzheimer’s |
Scale: + (mild) to +++ (strong)
British prescribers increasingly favour Exelon patches for dementia care due to improved adherence in elderly patients. During routine NHS medication reviews, these transdermal options often prove easier for caregivers to manage than daily tablets.
Key alternatives include:
- Aricept remains the most cost-effective starter option
- Ebixa addresses later-stage symptoms differently
- Specialist guidelines recommend Exelon specifically for Parkinson's-related dementia
Clinicians report that patient tolerance varies significantly between these cholinesterase inhibitors, necessitating individualised treatment approaches.
UK Market Availability
Exelon maintains stable supply through major pharmacies like Boots and Lloyds, though patch formulations occasionally face back-orders requiring advance ordering for dementia patients. Current pricing structures position capsules at £45-£65 monthly, while transdermal versions cost £85-120 per pack under NHS prescription.
Notable market shifts include:
- Sales growth of 22% during 2023 reflecting demographic aging patterns
- Generic rivastigmine formulations now covering 35% of NHS prescriptions
- Freeze-dried oral solutions becoming preferred in care homes due to 90-day stability
Pharmacy technicians report increased demand for dosage guidance as supply patterns fluctuate. Patients may experience temporary shortages but alternative strengths usually remain accessible via the NHS prescription service.
Research & Future Directions
The HIGH-MET trial (2023) demonstrated Exelon patches potentially slowing cognitive decline by 29% in mild impairment cases when used preventatively. This positions transdermal delivery as increasingly significant in early dementia intervention strategies ahead of upcoming patent expirations.
Ongoing developments focus on:
- Novel implantable microchip patches currently in Phase II trials
- European generic market expansion post-2024 patent expiry
- Formulation enhancements targeting reduced skin irritation
Leading consultants highlight transdermal delivery's practical advantages. As the Royal College of Psychiatrists notes: "Transdermal application significantly reduces nursing burdens within residential care settings". Research continues exploring Exelon's potential beyond neurodegenerative conditions.
Patient Usage Guidelines
Correct administration significantly impacts Exelon's effectiveness and tolerance. Take capsules with morning and evening meals to minimise digestive discomfort, pressing transdermal patches firmly onto clean, dry skin for 30 seconds. Rotate application sites like thighs or upper back to prevent irritation.
Essential storage protocols:
- Maintain capsules at 15-30°C and discard if discoloured
- Protect patches from heat – store below 25°C
- Oral solutions remain stable for 90 days post-opening when refrigerated
Serious errors include modifying patches or accidental double-dosing. As emphasised in the 2024 Medicines CoSHH Regulations, regular weight monitoring is mandatory due to potential appetite suppression. If a dose gets missed, wait until the next scheduled administration rather than taking extra – maintaining dosage intervals proves critical with dementia medications.
