Careprost

Introduction

Careprost is an ophthalmic solution that contains the prostaglandin analogue Bimatoprost. It is supplied as sterile eye drops and is primarily prescribed for the reduction of intra‑ocular pressure (IOP) in patients with open‑angle glaucoma or ocular hypertension. In the United Kingdom, the medication is used under the supervision of an ophthalmologist or optometrist and is recognised by the Medicines and Healthcare products Regulatory Agency (MHRA) as a prescription‑only medicine. Although its main indication is glaucoma management, the same pharmacological activity that lowers IOP also stimulates eyelash growth, a secondary effect that has been documented in clinical studies.

What is Careprost?

Careprost is a sterile ophthalmic solution (.03 % w/v) whose sole active ingredient is Bimatoprost. Bimatoprost belongs to the prostaglandin‑F₂α (PGF₂α) analogue class, which was originally developed for the treatment of elevated intra‑ocular pressure. The product is manufactured in GMP‑certified facilities; many commercial batches are supplied by Sun Pharma and other licensed overseas producers that meet European Union quality standards. Careprost is the generic formulation of the branded product Latisse® (used for eyelash enhancement) and Lumigan® (used for glaucoma). As a generic, it delivers the same therapeutic effect as the reference medicines while offering a lower acquisition cost.

How Careprost Works

Bimatoprost exerts its effect by binding to prostaglandin‑type FP receptors located on the ciliary muscle and trabecular meshwork. Activation of these receptors leads to remodeling of extracellular matrix proteins, resulting in increased outflow of aqueous humor through the uveoscleral pathway. The enhanced drainage reduces the volume of fluid within the anterior chamber, thereby lowering intra‑ocular pressure. In the eyelash follicle, the same FP‑receptor activation stimulates the anagen (growth) phase, producing longer, thicker lashes.

Pharmacokinetic data show that peak plasma concentrations occur within 1–2 hours after a single drop, but systemic exposure is minimal because the drug is largely retained within ocular tissues. The ocular half‑life is approximately 2 hours, while the therapeutic effect on IOP persists for about 24 hours, supporting once‑daily dosing.

Conditions Treated with Careprost

• Open‑angle glaucoma – The most common form of glaucoma in the UK, affecting roughly 2 % of adults over 40 years. Reducing IOP is the only proven strategy to slow optic nerve damage.
• Ocular hypertension – Elevated IOP without optic nerve damage; untreated patients have a 10 %–15 % risk of progressing to glaucoma each year.
• Eyelash hypotrichosis – A cosmetic indication for patients who desire longer, fuller eyelashes. While not an FDA‑approved therapeutic use in the UK, the effect is well documented in peer‑reviewed trials.

The drug’s ability to increase aqueous outflow makes it a first‑line option in the British National Formulary (BNF) for patients who cannot tolerate beta‑blockers or carbonic anhydrase inhibitors.

Who is Careprost For?

• Patients diagnosed with primary open‑angle glaucoma who require daily IOP reduction and have no contraindication to prostaglandin analogues.
• Individuals with ocular hypertension who need long‑term pressure control but prefer a once‑daily regimen.
• Adults experiencing inadequate eyelash growth (hypotrichosis) who have been evaluated by a qualified clinician and for whom a prostaglandin analogue is appropriate.
• Patients intolerant of other IOP‑lowering agents (e.g., beta‑blockers causing bronchospasm, carbonic anhydrase inhibitors causing renal impairment).

Careprost is not suitable for:

• Children under 12 years of age (insufficient safety data).
• Patients with known hypersensitivity to Bimatoprost, any excipients (benzalkonium chloride, sodium phosphate buffers), or other prostaglandin analogues.
• Individuals with active intra‑ocular inflammation, infection, or recent ocular surgery (within 4 weeks).

Risks, Side Effects, and Interactions

Common

• Conjunctival hyperaemia (eye redness) – occurs in up to 70 % of users; usually mild and transient.
• Eyelash changes – increased length, thickness, and darkness; may be desirable or cause irritation.
• Eye irritation or foreign‑body sensation – reported in up to 30 % of patients during the first weeks of therapy.

Rare

• Periocular skin hyperpigmentation – darkening of the eyelid or surrounding skin in <5 % of cases.
• Dry eye syndrome – reduced tear production leading to discomfort; managed with lubricating drops.

Serious

• Uveitis or iritis – inflammation of the uveal tract; requires immediate ophthalmic evaluation.
• Severe allergic reaction – angioedema, swelling of the eyelids, or systemic hypersensitivity (rare).
• Significant IOP increase – paradoxical rise in pressure; may necessitate discontinuation and alternative therapy.

Drug‑Drug Interactions

• Non‑steroidal anti‑inflammatory eye drops (e.g., ketorolac) – may reduce the IOP‑lowering effect of Bimatoprost.
• Topical beta‑blockers – concurrent use can produce additive IOP reduction; monitor for hypotension or bradycardia in systemic absorption cases.
• Systemic prostaglandin analogues – theoretical risk of additive side effects, though clinical relevance is low.

Patients should inform their eye‑care professional of any other ocular medications, including over‑the‑counter lubricants or antihistamine drops.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing – one drop (approximately .05 mL) instilled into the affected eye(s) once daily in the evening. The evening schedule aligns with the natural nocturnal rise in IOP and reduces the likelihood of transient blurred vision.
• Missed dose – if a dose is forgotten, apply it as soon as remembered unless it is within 2 hours of the next scheduled dose; in that case, skip the missed dose and resume the regular schedule. Do not double‑dose.
• Overdose – accidental administration of more than one drop per eye is unlikely to cause severe systemic toxicity due to low absorption. However, patients should rinse the ocular surface with sterile saline and seek medical advice if they experience persistent eye pain, vision changes, or systemic symptoms such as headache or nausea.
• Precautions – avoid contact lenses for at least 15 minutes after instillation to prevent drug absorption into the lens material. Alcohol consumption does not interfere with the medication, but patients with severe liver or kidney disease should have IOP monitored more frequently.

FAQ

• Is Careprost approved for use in children in the UK?
  Careprost has not been approved for pediatric use. Clinical trials have focused on adults, and safety data for children under 12 years are insufficient. Ophthalmologists generally avoid prescribing prostaglandin analogues to young patients unless a specialist recommendation is made.

• Can I travel internationally with Careprost eye drops?
  Yes, the medication can be carried in hand luggage, provided the container complies with airline liquid restrictions (generally ≤100 mL). Keep the bottle in its original packaging with the label visible, and declare it at security if asked.

• Does the formulation contain preservatives that could irritate sensitive eyes?
  Careprost includes benzalkonium chloride (BZK) as a preservative, which helps maintain sterility. While BZK is well tolerated by most patients, individuals with severe dry‑eye syndrome or known BZK sensitivity may experience increased irritation.

• How does the cost of generic Bimatoprost compare with the branded alternatives?
  Generic Bimatoprost products such as Careprost are typically 40 %–60 % cheaper than the branded formulations Lumigan® or Latisse®. The price difference reflects the lack of brand‑related marketing expenses while maintaining identical clinical efficacy.

• Are there any known differences between EU‑ and US‑marketed Bimatoprost formulations?
  Both markets use a .03 % w/v Bimatoprost solution with similar buffering agents. Minor variations may exist in preservative concentration or bottle material (plastic vs glass), but these do not affect therapeutic outcome.

• What should I do if I experience darkening of the skin around my eye?
  Periocular hyperpigmentation is a recognized, though uncommon, side effect. If the discoloration is bothersome, discuss discontinuation or switching to an alternative IOP‑lowering agent with your eye‑care professional. The change may reverse over several months after stopping the drug.

• Can I use other eye drops (e.g., artificial tears) together with Careprost?
  Artificial tears that do not contain preservatives can be used without affecting the IOP‑lowering action of Bimatoprost. Apply artificial tears at least 5 minutes before or after Careprost to avoid dilution of the active compound.

• Is there a risk of a positive drug test for Bimatoprost?
  Bimatoprost is not screened for in standard occupational drug‑testing panels. Its chemical structure does not interfere with typical immunoassays used for substances such as cannabinoids, opioids, or stimulants.

• What is the shelf‑life of an unopened Careprost bottle?
  Unopened bottles retain full potency for 24 months when stored at 15 °C–30 °C, protected from direct sunlight and moisture. Once opened, the solution should be used within 30 days, as recommended by the manufacturer.

• How does Careprost differ from other prostaglandin analogues like latanoprost?
  Bimatoprost (Careprost) is a prostamide, structurally related but not identical to prostaglandin analogues such as latanoprost. Clinical studies suggest Bimatoprost may achieve slightly greater IOP reduction (≈1–2 mm Hg) in certain patients, though individual response varies.

• Can Careprost be stored in a refrigerator to extend its stability?
  Refrigeration is unnecessary and may cause condensation that compromises sterility. The recommended storage condition is a cool, dry place at room temperature, away from heat sources.

• Is it safe to use Careprost if I have a history of asthma?
  Systemic absorption of Bimatoprost is minimal, so respiratory side effects are rare. However, patients with severe, uncontrolled asthma should discuss any prostaglandin analogue use with their clinician, as theoretical bronchospasm risk exists.
