Quick Answer
Pregastar 75 mg contains pregabalin, an alpha-2-delta calcium-channel ligand licensed for neuropathic pain (diabetic neuropathy, post-herpetic neuralgia, central neuropathic pain), generalised anxiety disorder, fibromyalgia, and as an adjunct in partial-onset seizures. The 75 mg capsule is the standard starting dose: 75 mg twice daily, increasing to 150 mg twice daily after 3–7 days if tolerated. Pregabalin reaches peak effect within 1 hour and has 90%+ bioavailability — far more predictable than gabapentin.

What Is Pregastar 75?
Pregastar 75 is an Indian-manufactured generic of pregabalin, a structural analogue of GABA. Despite that structural similarity, pregabalin does not bind GABA-A or GABA-B receptors and does not act as a GABA mimic. Instead, it binds the alpha-2-delta-1 subunit of voltage-gated calcium channels in the central nervous system, which reduces the calcium-dependent release of excitatory neurotransmitters (glutamate, noradrenaline, substance P) at hyperexcitable nerve terminals. This is the core mechanism that explains pregabalin’s effect on neuropathic pain and anxiety alike.
Why Pregabalin Over Gabapentin?

| Time to peak | 1 hour | 2–3 hours |
| Daily dose splits | Twice daily (rarely TDS) | Three times daily |
| Typical effective dose | 150–600 mg/day | 1800–3600 mg/day |
| Onset of relief | Often within 1 week | 2–4 weeks of titration |
| Anxiolytic licence | Yes (GAD) | No (off-label only) |
Indications
- Peripheral neuropathic pain — diabetic neuropathy, post-herpetic neuralgia, post-traumatic nerve injury
- Central neuropathic pain — spinal cord injury, multiple sclerosis
- Generalised anxiety disorder (GAD)
- Fibromyalgia (FDA approved indication; mixed European licensing)
- Adjunctive therapy in partial-onset seizures in adults
Dose & Administration
| Indication | Starting | Titration | Effective range |
|---|---|---|---|
| Neuropathic pain | 75 mg twice daily | To 150 mg BD after 3–7 days | 300–600 mg/day |
| Generalised anxiety | 75 mg twice daily | To 150–300 mg BD | 150–600 mg/day |
| Fibromyalgia | 75 mg twice daily | Escalate to 150 mg BD then 225 mg BD | 300–450 mg/day |
| Partial-onset seizures (adjunct) | 75 mg twice daily | Escalate weekly | 150–600 mg/day |
| Renal impairment (CrCl 30–60) | Halve dose | Slower | Adjust to renal function |
| Renal impairment (CrCl 15–30) | 25–75 mg/day | Cautious | Specialist guidance |
How to take: swallow whole, with or without food. Pregabalin can be taken at the same time daily for best plasma stability. Doses are usually morning and evening with at least 8 hours between them.

Frequently Asked Questions
Is Pregastar 75 the same as Lyrica?
Yes — both contain pregabalin as the active ingredient. Pregastar 75 is a WHO-GMP certified Indian generic of Lyrica 75 mg. Mechanism, dosing, and clinical effect are identical at the same milligram dose.
How quickly does Pregastar work for nerve pain?
Pregabalin’s anti-pain effect builds over the first 7–14 days. Many patients notice meaningful relief within the first week — faster than gabapentin, which typically takes 2–4 weeks. If 600 mg/day for 4 weeks gives no benefit, an alternative class is appropriate.
What is the maximum daily dose of pregabalin?
The licensed maximum is 600 mg/day, divided into two or three doses. Doses above 300 mg/day require careful renal dose calculation in patients with reduced kidney function.
Does pregabalin cause weight gain?
Yes — average gain is 2–4 kg over 12 weeks of treatment. Increased appetite and fluid retention both contribute. Weight gain is dose-dependent and usually plateaus.
Can I drink alcohol on Pregastar?
No. The combination amplifies sedation, dizziness, slowed breathing, and impaired coordination. The risk extends beyond the day of drinking — pregabalin’s half-life means residual effects last 24+ hours.
Is Pregastar safe to take with my opioid pain medication?
Combination requires caution. Pregabalin and opioids both depress the central nervous system and have been linked to higher rates of fatal respiratory depression when combined. Use the lowest effective dose of each, monitor for excessive sedation, and never start both at the same time.
Is pregabalin a controlled substance?
Yes — it is Schedule V in the United States and a Class C / Schedule 3 controlled drug in the United Kingdom. This reflects documented abuse potential, particularly in patients with a substance-misuse history.
Can I take Pregastar in pregnancy?
European regulators recommend avoiding pregabalin in pregnancy unless clearly necessary, after observational data suggested a small increase in major malformations. Discuss any planned or current pregnancy with your prescriber before continuing.
How is Pregastar different from gabapentin?
Same molecular target (alpha-2-delta calcium-channel subunit) but pregabalin has linear, predictable absorption and works at far lower milligram doses (150–600 mg vs. 1800–3600 mg). It is also licensed for generalised anxiety disorder, which gabapentin is not.
Will pregabalin help my anxiety?
Yes — pregabalin is licensed for generalised anxiety disorder (GAD) in many countries. Onset of anxiolytic effect is typically within 1 week, faster than SSRIs. It is not first-line for panic disorder or PTSD.
Can I drive while taking Pregastar?
Caution is essential — particularly in the first 1–2 weeks and after any dose increase. Dizziness, drowsiness, and impaired vision are common. Do not drive until you know how it affects you, and review driving regulations in your jurisdiction.
For patients on pregabalin who need a lower-cost first-line gabapentinoid, Gabasign (gabapentin 100/300/400/600/800 mg) covers the same neuropathic-pain indications at a more accessible price point — gabapentin is the WHO-Essential-Medicines-listed gabapentinoid and remains preferred for diabetic peripheral neuropathy and post-herpetic neuralgia.
