Dicycloverine Hydrocholoride 20mg Tablets
Dicycloverine hydrochloride 20mg
Dicycloverine hydrochloride 20mg Tablets are white oval biconvex tablets with 'S176' on one side.
Smooth muscle antispasmodic primarily indicated for treatment of functional conditions involving smooth muscle spasm of the gastrointestinal tract.
Route of administration: Oral
Adults and children over 12 years:
1 tablet three times a day before or after meals.
Hypersensitivity to dicycloverine hydrochloride or any of the excipients listed in section 6.1
Known idiosyncrasy to dicycloverine hydrochloride.
Products containing dicycloverine hydrochloride should be used with caution in any patient with or suspected of having glaucoma or prostatic hypertrophy. Use with care in patients with hiatus hernia associated with reflux oesophagitis because anticholinergic drugs may aggravate the condition.
Epidemiological studies in pregnant women with products containing dicycloverine hydrochloride (at doses up to 40mg/day) have not shown that dicycloverine hydrochloride increases the risk of foetal abnormalities if administered during the first trimester of pregnancy. Reproduction studies have been performed in rats and rabbits at doses of up to 100 times the maximum recommended dose (based on 60mg per day for an adult person) and have revealed no evidence of impaired fertility or harm to the foetus due to dicycloverine hydrochloride. Since the risk of teratogenicity cannot be excluded with absolute certainty for any product, the drug should be used during pregnancy only if the benefit outweighs the risk.
It is not known whether dicycloverine is secreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when dicycloverine is administered during breast-feeding.
Side-effects seldom occur with dicycloverine tablets. However, in susceptible individuals, dry mouth, thirst and dizziness may occur. On rare occasions, fatigue, sedation, blurred vision, rash, constipation, anorexia, nausea and vomiting, headache and dysuria have also been reported.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at : www.mhra.gov.uk/yellowcard.
Symptoms of dicycloverine overdosage are headache, dizziness, nausea, dry mouth, difficulty in swallowing, dilated pupils and hot dry skin. Treatment may include emetics, gastric lavage and symptomatic therapy if indicated.
Dicycloverine hydrochloride relieves smooth muscle spasm of the gastrointestinal tract.
Animal studies indicate that this action is achieved via a dual mechanism;
(1) a specific anticholinergic effect (antimuscarinic at the ACh-receptor sites) and
(2) a direct effect upon smooth muscle (musculotropic).
After a single oral 20mg dose of dicycloverine hydrochloride in volunteers, peak plasma concentration reached a mean value of 58ng/ml in 1 to 1.5 hours. 14C labelled studies demonstrated comparable bioavailability from oral and intravenous administration. The principal route of elimination is via the urine.
