What is Drotaverine Hydrochloride?
Drotaverine Hydrochloride, the active ingredient in No-Spa, is a phosphodiesterase-4 inhibitor presented as an oral tablet for oral use. It relieves smooth‑muscle spasm associated with abdominal pain, menstrual cramps, biliary colic, renal colic and urinary tract spasm in adults.
GNH USA supplies No-Spa as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.
What is Drotaverine Hydrochloride used for?
Drotaverine Hydrochloride is an antispasmodic that acts on smooth‑muscle disorders.
- Abdominal pain: provides relief of visceral pain by relaxing gastrointestinal smooth muscle. - Menstrual cramps: reduces uterine muscle contractions, easing dysmenorrhea. - Biliary colic: alleviates gallbladder spasm, improving pain control. - Renal colic: relaxes ureteral smooth muscle to facilitate stone passage. - Urinary tract spasm: diminishes bladder neck and urethral tone, reducing discomfort.
What are the side effects of Drotaverine Hydrochloride?
Adverse reactions may occur with any antispasmodic therapy.
Common Side Effects: - Nausea: mild gastrointestinal upset. - Dizziness: transient light‑headedness. - Dry mouth: reduced salivary secretion. - Headache: mild to moderate intensity. - Hypotension: occasional drop in blood pressure. - Blurred vision: temporary visual disturbance.
Serious or Rare Side Effects: - Allergic reactions: rash, pruritus, or angioedema. - Severe hypotension: marked blood pressure fall requiring medical attention. - Hepatic dysfunction: elevated liver enzymes. - Arrhythmia: irregular heart rhythm. - Blood dyscrasias: leukopenia or thrombocytopenia. - Anaphylaxis: life‑threatening systemic reaction.
What precautions apply to Drotaverine Hydrochloride?
Before using No-Spa, consider the following safety measures.
- Cardiovascular assessment: evaluate for existing hypotension or heart disease. - Hepatic function: use with caution in patients with liver impairment. - Hypersensitivity: avoid if known allergy to drotaverine or excipients. - Concomitant vasodilators: monitor for additive blood‑pressure effects. - Medical supervision: ensure use is directed by a qualified healthcare professional. - Store at room temperature: keep in the original pack, protect from moisture and direct sunlight.
What does Drotaverine Hydrochloride interact with?
Drotaverine may interact with other medicines; awareness of the interaction level is important.
Major Interactions (Avoid): - Potent vasodilators: concurrent use can cause excessive hypotension. - Other phosphodiesterase inhibitors (e.g., papaverine): may amplify smooth‑muscle relaxation.
Moderate Interactions (Monitor Closely): - Antihypertensive agents: may require blood‑pressure monitoring. - Anticholinergic drugs: combined effect on smooth muscle may increase adverse events. - CYP3A4 inhibitors (e.g., ketoconazole): can raise drotaverine plasma levels, necessitating dose adjustment.
