🟣 Category 4: Gabapentinoids

Gabapentinoids are the “hidden misuse” class — covered in Part 21 (Pregabalin) and Part 22 (Gabapentin).

Pregabalin and Gabapentin dominate this guide with the highest number of combination formulations in the entire PMBJP catalogue. Their pairing with Methylcobalamin, Nortriptyline, and Duloxetine reflects their primary clinical use in diabetic neuropathy — a condition affecting 25+ million Indians.

A. Pregabalin (Part 21)

Full Name	Pack Size	MRP (₹)	Per-Unit
Pregabalin Capsules IP 75 mg	10’s	20.63	₹2.06/cap
Pregabalin Tablets 75 mg	10’s	22.69	₹2.27/tab
Pregabalin Tablets IP 150 mg	10’s	28.13	₹2.81/tab
Pregabalin 75 mg + Nortriptyline 10 mg Tablets	10’s	31.97	₹3.20/tab
Pregabalin 50 mg + Duloxetine (DR) 20 mg Capsules	10’s	32.82	₹3.28/cap
Pregabalin 75 mg + Methylcobalamin 750 mcg Tablets	10’s	35.63	₹3.56/tab
Pregabalin 75 mg + Methylcobalamin 750 mcg Capsule IP	10’s	36.10	₹3.61/cap
Etoricoxib 60 mg + Pregabalin 75 mg (SR) Tablets	10’s	37.50	₹3.75/tab
Pregabalin 75 mg + Methylcobalamin 1500 mcg + Nortriptyline 10 mg	10’s	42.19	₹4.22/tab
Pregabalin 75 mg + Duloxetine (DR) 20 mg Capsules	10’s	42.19	₹4.22/cap
Pregabalin (SR) 75 mg + Methylcobalamin 1500 mcg	10’s	46.88	₹4.69/tab
Pregabalin 75 mg + Duloxetine (DR) 30 mg Capsules	10’s	46.88	₹4.69/cap

One-Liner: Pregabalin leads with 12 formulations in the PMBJP catalogue — more than any other substance in this series. At ₹2.06/capsule for the plain 75 mg, it is a fraction of branded Lyrica (₹15–20/capsule). Pregabalin is currently India’s fastest-growing substance of misuse after Tramadol, driven by its euphoric “body high” at doses above 300 mg.

B. Gabapentin (Part 22)

Full Name	Pack Size	MRP (₹)	Per-Unit
Gabapentin Tablets IP 100 mg	10’s	14.44	₹1.44/tab
Gabapentin 200 mg + Nortriptyline 10 mg Tablets	10’s	18.75	₹1.88/tab
Gabapentin 100 mg + Nortriptyline 10 mg Tablet	15’s	23.44	₹1.56/tab
Gabapentin Capsules IP 300 mg	10’s	25.79	₹2.58/cap
Gabapentin 100 mg + Methylcobalamin 500 mcg Tablets	10’s	34.04	₹3.40/tab
Gabapentin 300 mg + Methylcobalamin 500 mcg Tablet	10’s	37.50	₹3.75/tab
Gabapentin 400 mg + Nortriptyline 10 mg Tablets	10’s	51.57	₹5.16/tab
Gabapentin 300 mg + Amitriptyline 10 mg Tablets	10’s	51.57	₹5.16/tab
Gabapentin 6% + Lignocaine 5% + Baclofen 2% Gel	30 g	60.94	₹2.03/g

One-Liner: Gabapentin has 9 formulations including a unique topical gel (Gabapentin + Lignocaine + Baclofen) for localized neuropathic pain at ₹60.94 per tube. The plain 100 mg tablet at ₹1.44 is roughly 1/10th the price of branded Gabantin.

[!NOTE] The Methylcobalamin Connection: Multiple Pregabalin and Gabapentin formulations include Methylcobalamin (active Vitamin B12). This is because diabetic neuropathy — the primary indication — is often worsened by B12 deficiency caused by Metformin, the most common diabetes drug.

🟤 Category 5: Muscle Relaxants

Covered in Parts 24 (Baclofen), 25 (Tizanidine), and 26 (Chlorzoxazone).

A. Baclofen (Part 24)

Full Name	Pack Size	MRP (₹)	Per-Unit
Baclofen Tablets IP 10 mg	10’s	11.00	₹1.10/tab
Baclofen 20 mg ER (Gastric Retentive) Tablets	10’s	30.00	₹3.00/tab

One-Liner: Baclofen 10 mg — the GABA-B agonist used for spasticity and increasingly studied for alcohol dependence — costs just ₹1.10 per tablet. The ER formulation at ₹3.00/tablet uses “gastric retentive” technology to float in the stomach for sustained release.

B. Tizanidine (Part 25)

Full Name	Pack Size	MRP (₹)	Per-Unit
Tizanidine Tablets IP 2 mg	10’s	9.38	₹0.94/tab
Aceclofenac 100 mg + Paracetamol 325 mg + Tizanidine 2 mg	10’s	18.75	₹1.88/tab

One-Liner: Tizanidine — the alpha-2 adrenergic agonist muscle relaxant — costs ₹0.94 per tablet for the solo formulation. The triple-combination with Aceclofenac and Paracetamol (₹1.88/tab) is one of the most commonly prescribed pain combos in Indian orthopedic practice.

C. Chlorzoxazone (Part 26)

Full Name	Pack Size	MRP (₹)	Per-Unit
Aceclofenac 100 mg + Paracetamol 325 mg + Chlorzoxazone 250 mg	10’s	15.00	₹1.50/tab
Paracetamol 500 mg + Chlorzoxazone 250 mg Tablet	10’s	15.00	₹1.50/tab
Nimesulide 100 mg + Paracetamol 325 mg + Chlorzoxazone 375 mg	10’s	18.75	₹1.88/tab
Chlorzoxazone 500 mg + Diclofenac 50 mg + Paracetamol 325 mg	10’s	23.44	₹2.34/tab

One-Liner: Chlorzoxazone appears exclusively in combination formulations — never as a solo tablet. All 4 entries pair it with an analgesic (Paracetamol) and/or an NSAID, reflecting its clinical role as a “muscle relaxant add-on” rather than a standalone drug. The “Red Urine” side effect (harmless metabolite) alarms patients who aren’t warned in advance.

🔴 Category 6: Stimulants & Dissociatives

A. Modafinil (Part 28)

Full Name	Pack Size	MRP (₹)	Per-Unit
Modafinil 100 mg Tablets	10’s	46.88	₹4.69/tab
Modafinil Tablets IP 200 mg	10’s	78.75	₹7.88/tab

One-Liner: Modafinil 200 mg — the “Limitless Pill” favored by students and tech workers — costs ₹7.88 per tablet at Jan Aushadhi vs ₹30–50 for branded Modalert. Despite its “smart drug” reputation, it carries FDA warnings for Stevens-Johnson Syndrome and serious dermatologic reactions.

B. Dextromethorphan (Part 32)

Full Name	Pack Size	MRP (₹)	Per-Unit
Dextromethorphan HBr Syrup IP 13.5 mg/5 ml	50 ml	21.57	₹0.43/ml
Phenylephrine 5 mg + CPM 2 mg + DXM 10 mg Syrup	100 ml	23.44	₹0.23/ml
Phenylephrine 5 mg + CPM 2 mg + DXM 15 mg Syrup	100 ml	28.13	₹0.28/ml

One-Liner: DXM cough syrup — the dissociative that produces “plateau” effects at high doses — costs as little as ₹0.23/ml in combination form. A 100 ml bottle at ₹23.44 contains enough DXM for recreational misuse, making it one of the cheapest “highs” in India.

[!WARNING] The “Plateau” Danger: DXM at doses of 300+ mg (an entire 100 ml bottle of the 15 mg/5 ml formula) produces dissociative hallucinations, serotonin syndrome risk, and in extreme cases, “Olney’s lesions” — irreversible brain damage. See Part 32.
