Drug Class: Smooth Muscle Relaxant / Antispasmodic | Form: Oral Tablet | Prescription Status: Prescription Only (Rx) — DRAP Registered
What is Relispa Forte 80mg Tablet? Relispa Forte 80mg by Searle contains Drotaverine Hydrochloride — a highly selective smooth muscle relaxant that relieves painful spasms throughout the gastrointestinal, biliary, and urinary tracts without the anticholinergic side effects associated with older antispasmodics like Hyoscine. Unlike anticholinergic antispasmodics that block acetylcholine receptors throughout the body causing dry mouth, blurred vision, and urinary retention, Drotaverine acts directly on smooth muscle cells through phosphodiesterase-4 inhibition — providing targeted muscle relaxation confined to smooth muscle tissue. This selectivity makes Relispa Forte significantly better tolerated than older antispasmodics — particularly for patients with glaucoma, enlarged prostate, or cardiovascular conditions where anticholinergic medicines are contraindicated. It is suitable for short-term relief of acute spasm-related pain across multiple organ systems.
What is Relispa Forte 80mg Used For?
- Irritable bowel syndrome — cramping, spasm, and abdominal pain from IBS (آنتوں کی اینٹھن اور درد)
- Renal colic — severe cramping pain from kidney stone passage (گردے کی پتھری کا شدید درد)
- Biliary colic — gallbladder and bile duct spasm causing upper abdominal pain (پتے کا درد)
- Dysmenorrhoea — painful menstrual cramps from uterine smooth muscle spasm (ماہواری کا درد)
- Gastric and intestinal spasms — colicky abdominal pain from smooth muscle overactivity (پیٹ کی اینٹھن)
- Urinary tract spasms — bladder and ureteral spasm causing lower abdominal cramping (پیشاب کی نالی کی اینٹھن)
- Cholecystitis — biliary tract spasm in gallbladder inflammation under medical supervision
How Does it Work? Drotaverine selectively inhibits phosphodiesterase-4 enzyme in smooth muscle cells — preventing breakdown of cyclic AMP which normally promotes muscle relaxation. Elevated cyclic AMP levels cause smooth muscle cells to relax by reducing intracellular calcium availability for muscle contraction. This mechanism is highly selective for smooth muscle — producing effective spasmolytic action in gastrointestinal, biliary, and urinary tract smooth muscle without affecting cardiac or skeletal muscle and without blocking acetylcholine receptors throughout the body. The result is targeted visceral smooth muscle relaxation that relieves painful spasms rapidly without the systemic anticholinergic burden of older antispasmodic medicines.
Dosage and Administration
⚠️ Take as prescribed — do not exceed recommended daily dose. For menstrual pain take at the very first sign of cramping for best results. Can be taken with or without food. Not a substitute for treating the underlying cause of spasm — always consult doctor if pain is severe, persistent, or associated with fever.

Who Should NOT Take Relispa Forte 80mg?
- Allergy to Drotaverine or any component of the tablet
- Severe heart failure or significant cardiovascular disease — Drotaverine has mild vasodilatory effect on blood vessels
- Severe liver impairment — Drotaverine extensively metabolised by liver
- Severe kidney impairment — reduced clearance requires caution
- Severe hypotension — low blood pressure worsened by vasodilatory effect
- Children under 12 years — safety not established at adult dose
- Pregnancy — particularly first trimester; use only if clearly necessary under doctor supervision
- Breastfeeding — consult doctor before use
- Glaucoma — though Drotaverine lacks anticholinergic action, consult doctor before use
Side Effects
Common: Mild headache, mild dizziness, mild nausea, mild flushing — generally very well tolerated due to absence of anticholinergic effects that cause dry mouth and blurred vision with older antispasmodics.
Serious — Stop and seek medical attention immediately: Severe allergic reaction — sudden widespread rash, swelling of face or throat, difficulty breathing (فوری ہسپتال جائیں), significant drop in blood pressure with dizziness and fainting — particularly in dehydrated patients or those on antihypertensives (بے ہوشی — فوری مدد لیں), severe liver reactions — yellowing of skin or eyes with abdominal pain in rare cases (یرقان — فوری ڈاکٹر کو بتائیں), significant worsening of heart failure — sudden breathlessness with ankle swelling (فوری مدد لیں).
Drug Interactions
| Medicine | Interaction |
|---|---|
| Antihypertensives | Additive blood pressure lowering — increased hypotension and dizziness risk particularly on standing |
| Levodopa | Drotaverine may reduce antiparkinson effectiveness of Levodopa — use with caution in Parkinson's patients |
| Other antispasmodics (Hyoscine, Dicyclomine) | Additive smooth muscle relaxation — increased side effect risk |
| Morphine / Opioid pain medicines | Additive smooth muscle relaxation effects — combined use for renal colic under medical supervision only |
| Papaverine | Additive smooth muscle relaxing effects — avoid unsupervised combination |
| Alcohol (شراب) | May increase vasodilatory and blood pressure lowering effects — avoid during treatment |
Storage: Store below 25°C in a cool, dry place. Protect from moisture and direct sunlight. Keep out of reach of children (بچوں کی پہنچ سے دور رکھیں). Do not use after expiry date.
FAQs
Q: How is Relispa Forte different from older antispasmodics like Buscopan (Hyoscine)? Drotaverine acts directly on smooth muscle through phosphodiesterase inhibition — without blocking acetylcholine receptors anywhere in the body. This means no dry mouth, blurred vision, urinary retention, or rapid heartbeat that commonly occur with Hyoscine. Relispa Forte is therefore significantly better tolerated — particularly for elderly patients, those with glaucoma, enlarged prostate, or heart conditions where anticholinergic medicines are problematic.
Q: Can Relispa Forte 80mg be used safely during pregnancy for menstrual-type pain or uterine cramps? Drotaverine has been studied in obstetric settings — however it should only be used during pregnancy under explicit doctor supervision as uterine smooth muscle relaxation has implications for pregnancy maintenance and labour. For routine dysmenorrhoea management outside pregnancy it is generally well tolerated — always consult your doctor before using any antispasmodic medicine during pregnancy.
Q: Is Relispa Forte suitable for long-term use in patients with chronic IBS? Relispa Forte is primarily indicated for short-term acute spasm relief — for chronic IBS management a comprehensive treatment approach including dietary modification, stress management, and possibly long-term targeted therapy is more appropriate than relying on antispasmodics alone. Consult your gastroenterologist for a comprehensive chronic IBS management plan if symptoms are persistent and recurring.
