Gabica Tablet 75mg

About Gabica Tablet 75mg

Gabica Tablet Uses

• Neuropathic pain associated with diabetic peripheral neuropathy, including burning, tingling, shooting, and stabbing pain in the feet and hands.
• Postherpetic neuralgia, the persistent burning nerve pain that continues after a shingles rash has healed.
• Central neuropathic pain caused by spinal cord injury.
• Fibromyalgia, characterized by widespread musculoskeletal pain, fatigue, sleep disturbance, and cognitive difficulties.
• Adjunctive therapy for partial-onset seizures in adults with epilepsy, when added to existing antiepileptic regimens.
• Generalized anxiety disorder (GAD) in adults, where excessive worry and physical anxiety symptoms are present.
• Restless legs syndrome (Willis-Ekbom disease) as adjunctive or alternative therapy.

Gabica Tablet Benefits

• Effective for neuropathic pain, a type of pain caused by nerve damage that does not respond to standard analgesics such as paracetamol or NSAIDs.
• Provides significant relief from the burning, tingling, and shooting pain of diabetic neuropathy, one of the most common and undertreated conditions in Pakistan.
• Relieves anxiety symptoms without the dependence risks associated with benzodiazepines, making it a preferred option in patients requiring long-term anxiety management.
• Faster onset of analgesic effect compared to older anticonvulsants used for pain, with meaningful relief typically beginning within the first week.
• Available in multiple strengths from 25mg to 300mg, allowing dose titration from the lowest effective amount based on individual response and tolerability.

What Experts Say

Gabica contains Pregabalin, a second-generation alpha-2-delta ligand and structural analogue of GABA, approved for neuropathic pain, epilepsy, and generalized anxiety disorder.

How It Works

Pregabalin binds to the alpha-2-delta subunit of voltage-gated calcium channels in the central and peripheral nervous system. This binding does not block the calcium channel directly but reduces the trafficking of calcium channel subunits to the neuronal membrane, decreasing the density of functional calcium channels available for activation. The result is reduced calcium influx at presynaptic nerve terminals, which in turn decreases the release of excitatory neurotransmitters including glutamate, norepinephrine, and substance P. By damping down excessive neuronal firing and neurotransmitter release, Pregabalin reduces the hypersensitized pain signaling that characterizes neuropathic pain states and reduces the CNS overactivity associated with anxiety and seizures.

Why Pregabalin Works When Painkillers Do Not

Standard analgesics including paracetamol and NSAIDs work by reducing peripheral inflammation or blocking prostaglandin synthesis. Neuropathic pain does not arise from tissue inflammation but from abnormal electrical firing in damaged or sensitized nerve fibers. Because its origin is neurological rather than inflammatory, neuropathic pain is characteristically unresponsive to conventional analgesics. Pregabalin addresses the neurological mechanism directly, which is why it succeeds where paracetamol and ibuprofen fail. This distinction is clinically important for Pakistani patients with diabetic neuropathy who often continue taking ineffective analgesics for years before receiving appropriate neuropathic pain treatment.

Clinical Note

Pregabalin is a controlled substance in many countries due to its potential for misuse, dependence, and abuse. The FDA issued a black box warning in 2019 for serious, potentially fatal respiratory depression when Pregabalin is combined with opioids or other CNS depressants. Pregabalin must never be stopped abruptly as this can trigger withdrawal symptoms including insomnia, nausea, headache, and anxiety. The dose must always be tapered gradually. Patients with a history of substance abuse require careful assessment before starting Pregabalin.

Drug Class

• Alpha-2-Delta Ligand.
• Anticonvulsant and Analgesic.

Packaging and Quantity

• 1 pack contains 14 capsules (2 strips of 7 capsules each).
• Available in 25mg, 50mg, 75mg, 100mg, 150mg, and 300mg capsule strengths.

When Not to Use Gabica

• Known allergy or hypersensitivity to Pregabalin or any ingredient in the capsule.
• Concurrent use with opioid analgesics without medical supervision, due to the risk of serious respiratory depression.
• Children under 12 years of age.
• Patients with severe heart failure, as Pregabalin causes fluid retention and peripheral edema.

Gabica Tablet 75mg formula

• Pregabalin

Available forms

• Capsules

How to use Gabica Tablet 75mg?

• Gabica may be taken with or without food.
• The capsule should be swallowed whole with a full glass of water.
• Gabica must not be stopped suddenly. The dose must always be reduced gradually under doctor supervision to prevent withdrawal symptoms.
• Alcohol must be completely avoided throughout treatment as it significantly increases CNS depression and dizziness.
• The standard adult starting dose for neuropathic pain is 75mg twice daily or 50mg three times daily, increased based on response and tolerability. The maximum dose is 600mg per day. For generalized anxiety disorder, 150mg per day divided into two to three doses, increased to a maximum of 600mg per day as needed.
• The dose should not be changed or stopped without consulting the prescribing doctor. Full therapeutic effect may take 1 to 2 weeks to appear.

Drug Interactions

All current medicines, supplements, and herbal products must be disclosed to the prescribing doctor before starting Gabica. Key interactions include:

• Opioid analgesics including tramadol, codeine, and morphine: Combining with Pregabalin carries an FDA black box warning for serious respiratory depression, sedation, coma, and death. This combination must only be used under close medical supervision with the lowest effective doses.
• Alcohol: Concurrent use significantly enhances CNS depression, increasing the risk of sedation, respiratory depression, and impaired coordination. Alcohol must be strictly avoided.
• CNS depressants including benzodiazepines, sedatives, antihistamines, and antipsychotics: Additive CNS depression increases the risk of excessive sedation and respiratory compromise.
• Gabapentin: Combining Pregabalin with Gabapentin is generally not recommended as they share the same binding site and the combination does not provide additional benefit while increasing side effect risk.
• ACE inhibitors: Concurrent use may increase the risk of Pregabalin-associated angioedema.
• Diuretics: Pregabalin causes fluid retention; combining with diuretics may reduce their effectiveness in managing fluid overload.

Risks and warnings

• Respiratory depression (FDA Black Box Warning): Pregabalin combined with opioids significantly increases the risk of life-threatening respiratory depression. The lowest effective doses of both medicines should be used when the combination is medically necessary, and patients must be monitored closely.
• Dependence and misuse potential: Pregabalin is a controlled substance with documented potential for misuse, particularly in patients with a history of substance abuse. All patients should be assessed for abuse risk before starting treatment.
• Suicidality: All antiepileptic drugs including Pregabalin carry an FDA warning for increased risk of suicidal thoughts and behavior. Patients must be monitored closely for mood changes and suicidal ideation throughout treatment.
• Angioedema: Pregabalin has been associated with potentially fatal angioedema affecting the face, mouth, neck, and throat. Treatment must be stopped immediately and emergency care sought if these symptoms occur.
• Peripheral edema and heart failure: Pregabalin causes fluid retention. It must be used with caution in patients with heart failure, and any new or worsening edema during treatment must be reported to a doctor.
• Withdrawal: Gabica must never be stopped abruptly. Discontinuation syndrome including insomnia, nausea, headache, and anxiety occurs after prolonged use. The dose must always be tapered gradually under medical supervision.
• Driving and machinery: Pregabalin significantly impairs coordination, reaction time, and visual acuity. Driving and operating heavy machinery must be avoided until the individual response to treatment is fully established.
• Pregnancy: Pregabalin can cause fetal harm. Women of childbearing age must use effective contraception during treatment. It should only be used during pregnancy after specialist assessment when the benefit clearly outweighs the risk.
• Breastfeeding: Pregabalin passes into breast milk. Breastfeeding is not recommended during treatment.
• Elderly patients: Older adults are more sensitive to the CNS effects of Pregabalin. The starting dose should be lower and the dose escalation slower in patients above 65 years.

Gabica Capsule Side Effects

Most patients experience some degree of dizziness and drowsiness when starting Gabica, particularly in the first week. These effects are dose-dependent and often improve as the body adjusts to treatment.

• Dizziness, the most commonly reported side effect.
• Drowsiness or sedation.
• Peripheral edema (swelling in the hands, feet, or ankles).
• Weight gain with prolonged use.
• Dry mouth.
• Blurred or double vision.
• Difficulty concentrating or memory problems.
• Constipation or diarrhea.

Serious side effects require immediate medical attention:

• Respiratory depression, particularly when combined with opioids or CNS depressants.
• Angioedema presenting as swelling of the face, mouth, throat, or limbs. This is a rare but potentially life-threatening reaction requiring immediate emergency care.
• Suicidal thoughts or worsening depression, in line with the class-wide antiepileptic drug warning.
• Severe allergic reaction including widespread rash, blistering, or difficulty breathing.
• Signs of withdrawal when the medicine is reduced or stopped too quickly, including insomnia, nausea, sweating, and anxiety.

Storage Conditions
