What is Drotaverine Hydrochloride used for?
Drotaverine is an antispasmodic that acts on smooth muscle to alleviate spasm‑related conditions.
- Smooth muscle spasm: provides rapid relaxation of gastrointestinal, biliary and urinary tract muscles, reducing pain. - Abdominal pain: eases discomfort caused by intestinal cramping and colic. - Biliary colic: relieves spasms of the gallbladder and bile ducts, facilitating bile flow. - Renal colic: diminishes ureteral muscle contraction, helping to alleviate kidney‑stone pain. - Dysmenorrhea: reduces uterine muscle tone, decreasing menstrual cramps.
What are the side effects of Drotaverine Hydrochloride?
Adverse reactions may occur with drotaverine administration.
Common Side Effects: - Nausea: mild to moderate upset stomach. - Dizziness: transient light‑headedness. - Headache: occasional throbbing pain. - Flushing: temporary redness of the skin. - Hypotension: mild drop in blood pressure. - Injection site pain: discomfort at the site of IM/IV administration.
Serious or Rare Side Effects: - Anaphylactic reaction: severe allergic response requiring immediate medical attention. - Severe hypotension: marked blood‑pressure fall that may cause fainting. - Cardiac arrhythmia: irregular heart rhythm. - Hepatic dysfunction: abnormal liver enzyme elevations. - Blood dyscrasias: rare blood‑cell abnormalities such as agranulocytosis. - Stevens‑Johnson syndrome: severe skin and mucous membrane reaction.
What precautions apply to Drotaverine Hydrochloride?
Before using No‑Spa, consider the following safety measures.
- Assess cardiovascular status: monitor blood pressure prior to administration. - Avoid in patients with known hypersensitivity to drotaverine or related compounds. - Use caution in hepatic impairment: increase monitoring of liver function. - Concurrent use with other vasodilators: observe for additive hypotensive effects. - Pregnancy and lactation: evaluate risk–benefit as data are limited. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.
What does Drotaverine Hydrochloride interact with?
Drotaverine may interact with other medicines; awareness of the interaction level is essential.
Major Interactions (Avoid): - Concomitant use with potent vasodilators (e.g., nitroglycerin) may cause severe hypotension. - Co‑administration with strong CYP3A4 inhibitors may increase plasma concentrations of drotaverine.
Moderate Interactions (Monitor Closely): - Anticoagulants (e.g., warfarin): possible enhanced bleeding risk. - Antihistamines: may augment sedative effects. - Diuretics: monitor electrolyte balance and blood pressure.
