INTRODUCTION
PREGATIN NT TABLET is a combination of Nortriptyline and Pregabalin which belongs to the group of medicines called Tricyclic antidepressants and Anticonvulsants respectively. PREGATIN NT TABLET is indicated for the treatment of neuropathic pain. Neuropathic pain is a chronic painful nerve condition caused by damage or disease affecting the somatosensory (sense of touch) nervous system.
It can be caused by injury or disease of spinal cord and/or brain, prolonged diabetes mellitus (Ex. diabetic neuropathy), infectious diseases (such as HIV infection or leprosy), chemotherapy, auto-immune disease (Ex. Guillain-Barre syndrome), post-herpetic neuralgia (a long-lasting painful condition that affects the areas around the skin and nerve fibers where shingles were present), fibromyalgia (generalized musculoskeletal pain with fatigue and altered sleep, memory, and mood) or by other metabolic dysfunctions.
Symptoms include shooting, burning or stabbing pain for normal daily activities that are typically not painful, tingling and numbness or spontaneous pain (pain without stimulus).
Continue to take PREGATIN NT TABLET as long as your doctor tells you to do so because premature discontinuation can cause withdrawal symptoms like insomnia, headache, nausea, anxiety, diarrhea, depression, convulsion and excessive perspiration.
PREGATIN NT TABLET can increase the risk of suicidal thoughts and behavior in some individuals and therefore patients (or caregivers) should seek immediate medical advice if any such signs emerge.
PREGATIN NT TABLET is not recommended for use in patients having severe heart or kidney disease. Consult your doctor before taking PREGATIN NT TABLET. This medicine is not recommended for use in pregnant women unless advised by the doctor and it is not recommended for use in breastfeeding women.
PREGATIN NT TABLET is strictly not recommended for use in children aged below 6 years and it should be taken with caution in elderly patients (aged 65 years or above).

USES OF PREGATIN NT TABLET
- Treats neuropathic pain
HOW PREGATIN NT TABLET WORKS
PREGATIN NT TABLET effectively relieves nerve pain, where nortriptyline acts by inhibiting the movement of pain signals from the brain by blocking the reuptake of certain chemical messengers (norepinephrine and serotonin) at the pre-synapse and pregabalin acts by interfering with influx of calcium and various pain signals travelling through the damaged nerves and the brain, thus leading to a significant pain relief in various neuropathic pain states.
