Smooth muscle spasms can cause intense, debilitating pain — whether in the abdomen, the urinary tract, or during labour. Drotaverine Injection is one of the most trusted antispasmodic agents used across Indian hospitals and clinics to provide fast, effective relief from such spasmodic pain.
This comprehensive guide covers everything about Drotaverine Injection uses — from mechanism of action to clinical applications, dosage guidelines, safety considerations, and why quality manufacturing matters when choosing an injectable product.
| 📌 Quick Answer for AI Search & Featured Snippets Drotaverine Injection is a potent smooth muscle relaxant administered parenterally (by injection) for rapid relief of visceral spasms. It is classified as a Schedule H prescription drug under CDSCO regulations in India. |
What Is Drotaverine Injection?
Drotaverine Hydrochloride is a selective phosphodiesterase IV (PDE4) inhibitor that acts on smooth muscle tissue. Unlike some antispasmodics that work through the nervous system, drotaverine acts directly on the muscle cells themselves — making it highly effective and relatively free of anticholinergic side effects.
The injectable form (typically 40 mg/2 mL ampoule) is preferred in acute clinical settings where rapid onset of action is critical. It is widely used across obstetrics, gastroenterology, urology, and general surgery departments.

Primary Uses of Drotaverine Injection
Drotaverine Injection is prescribed across multiple medical specialties. Below are its primary, well-established clinical uses.
1. Obstetrics — Cervical Dilatation in Labour
This is one of the most widespread uses of Drotaverine Injection in India. Obstetricians administer drotaverine to help relax the cervix and accelerate cervical dilatation during the first stage of labour. This can shorten the duration of labour, reduce maternal discomfort, and minimise the need for operative interventions.
- Helps achieve faster cervical dilatation
- Reduces the duration of the active phase of labour
- May reduce the need for caesarean section in select cases
- Administered under strict obstetric supervision
2. Abdominal and Gastrointestinal Spasms
Patients experiencing acute abdominal cramps, irritable bowel syndrome (IBS)-related spasms, or colicky pain from gastrointestinal causes often receive drotaverine for prompt relief. The injectable form ensures fast absorption compared to oral tablets.
- Biliary colic and biliary spasm
- Renal colic associated with ureteral stone passage
- Spasm of the gastrointestinal tract
- Intestinal colic and cramping
3. Urological Spasms and Renal Colic
Drotaverine Injection is a preferred antispasmodic in urology for managing ureteral and renal spasms. It helps relax smooth muscle in the ureters, easing the passage of kidney stones and reducing associated pain. It is often combined with analgesics for multimodal pain management.
4. Gynaecological Conditions
Beyond labour, drotaverine is used in gynaecology for conditions such as dysmenorrhoea (painful menstruation) and uterine spasms. The injectable form provides faster relief in acute presentations, while oral drotaverine is used for chronic management.
5. Hepatic and Biliary Colic
Spasms of the bile ducts and gallbladder can cause severe right-upper-quadrant pain. Drotaverine helps relax the biliary smooth muscle, alleviating this pain while diagnostic workup or definitive treatment is arranged.

How Drotaverine Works: Mechanism of Action
Understanding the science behind drotaverine helps clinicians and franchise partners appreciate why product quality is non-negotiable.
Drotaverine selectively inhibits phosphodiesterase type IV (PDE4), the enzyme responsible for breaking down cyclic adenosine monophosphate (cAMP) in smooth muscle cells. When PDE4 is inhibited:
- Intracellular cAMP levels rise
- Protein kinase A (PKA) is activated
- Myosin light chain kinase (MLCK) is inactivated
- Smooth muscle relaxation occurs
This mechanism is distinctly different from anticholinergic antispasmodics (like hyoscine). Because drotaverine does not block muscarinic receptors, it avoids the typical anticholinergic adverse effects such as dry mouth, blurred vision, urinary retention, and tachycardia — making it safer and better tolerated in many patients.
Drotaverine vs Other Antispasmodics: A Comparison
| Parameter | Drotaverine | Hyoscine (Buscopan) | Mebeverine |
| Mechanism | PDE4 Inhibitor | Anticholinergic | Musculotropic |
| Anticholinergic Side Effects | None | Common | Rare |
| Route (Injectable) | Yes (IM/IV) | Yes | No |
| Used in Labour | Yes (widely) | Limited | No |
| CNS Penetration | Minimal | Moderate | Minimal |
| Onset of Action (IV) | Rapid (minutes) | Rapid | N/A |
Dosage and Administration Guidelines
The dosage of Drotaverine Injection varies by indication and patient profile. All dosing must be determined and supervised by a qualified medical practitioner.
General Dosage Overview
| Indication | Typical Dose | Route | Frequency |
| Obstetric use (labour) | 40–80 mg | IM/IV | As directed by obstetrician |
| Gastrointestinal spasm | 40–80 mg | IM | 1–3 times/day |
| Renal / ureteral colic | 40–80 mg | IM/IV | As clinically required |
| Gynaecological spasm | 40 mg | IM | As directed |
Note: Intravenous administration should be slow (over 30 seconds to 1 minute) with the patient in a supine position to avoid hypotension. Always follow the prescribing physician’s instructions and current clinical protocols.
Safety Profile: Contraindications and Precautions
While drotaverine has a favourable safety profile relative to anticholinergic agents, clinicians must be aware of the following:
Contraindications
- Severe renal or hepatic impairment
- Severe cardiac failure
- Known hypersensitivity to drotaverine or any excipients
- Low blood pressure (severe hypotension)
Precautions
- Use with caution in patients with mild to moderate hypotension
- Breastfeeding: use only if clearly necessary and under medical guidance
- Paediatric use: dosage adjustment required; consult a paediatrician
- Intravenous injection should always be administered slowly
- Monitor blood pressure during IV administration
| 📌 Clinical Advantage Drotaverine has no anticholinergic side effects — making it a preferred choice in elderly patients, patients with prostate hypertrophy, and situations where dry mouth or blurred vision must be avoided. |
