What is Drotaverine Hydrochloride?
Drotaverine Hydrochloride, the active ingredient in No-Spa Forte, is a phosphodiesterase inhibitor (smooth muscle relaxant) presented as an oral dosage form for oral use. It is employed to relieve smooth‑muscle spasm‑related pain in the gastrointestinal, urinary and biliary tracts, as well as dysmenorrhea.
GNH USA supplies No‑Spa Forte as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, ensuring quality‑controlled batches, regulatory compliance and reliable logistics for cross‑border procurement.
What is Drotaverine Hydrochloride used for?
No‑Spa Forte (drotaverine hydrochloride) is an antispasmodic that acts on smooth muscle to alleviate spasm‑related conditions.
- Abdominal pain due to smooth muscle spasm: reduces intensity of pain by relaxing gastrointestinal smooth muscle. - Menstrual cramps (dysmenorrhea): eases uterine muscle contractions, decreasing cramp severity. - Biliary colic: relaxes biliary tract smooth muscle, facilitating bile flow and relieving pain. - Urinary tract spasm: diminishes bladder and ureteral smooth‑muscle tone, improving discomfort.
What are the side effects of Drotaverine Hydrochloride?
Adverse reactions to No‑Spa Forte are generally uncommon but may occur.
Common Side Effects: - Nausea: mild gastrointestinal upset. - Dizziness: transient light‑headedness. - Headache: mild to moderate intensity. - Dry mouth: reduced salivation. - Hypotension: occasional drop in blood pressure. - Blurred vision: temporary visual disturbance.
Serious or Rare Side Effects: - Allergic reactions: rash, itching, swelling, or anaphylaxis. - Severe hypotension: marked blood‑pressure decline requiring medical attention. - Cardiac arrhythmias: irregular heart rhythm in susceptible individuals. - Hepatic dysfunction: elevated liver enzymes. - Blood dyscrasias: rare cases of leukopenia or thrombocytopenia.
What precautions apply to Drotaverine Hydrochloride?
Before initiating therapy, consider the following safety measures.
- Pregnancy: safety not established; use only if clearly needed. - Breastfeeding: unknown; weigh benefits against potential risks. - Renal impairment: monitor renal function as drug is excreted renally. - Hepatic impairment: dose adjustment may be required. - Concomitant antihypertensives: may enhance hypotensive effect. - Store at ambient temperature (below 25 °C): keep in original packaging, protect from moisture.
What does Drotaverine Hydrochloride interact with?
Drug interaction assessment should include both major and moderate considerations.
Major Interactions (Avoid): - Co‑administration with other potent smooth‑muscle relaxants: risk of excessive hypotension. - Use with strong CYP3A4 inhibitors (if applicable): may increase plasma concentrations. - Combination with other phosphodiesterase inhibitors: heightened risk of cardiovascular effects.
Moderate Interactions (Monitor Closely): - Antihypertensive agents: may require dose adjustment for blood‑pressure control. - Anticholinergic drugs: potential increase in dry‑mouth symptoms. - Diuretics: monitor electrolytes and blood pressure. - NSAIDs: watch for additive gastrointestinal irritation. - Alcohol: may potentiate dizziness or hypotension.
