Drug Nomenclature

Date of monograph revision: 29-Apr-2004; 10-May-2004; 02-Feb-2005; 20-Jul-2006
Synonyms: Senósidos
CAS: 81-27-6 (sennoside A); 128-57-4 (sennoside B); 52730-36-6 (sennoside A, calcium salt); 52730-37-7 (sennoside B, calcium salt)

Pharmacopoeias. In US.

The United States Pharmacopeia 31, 2008 (Sennosides). A partially purified natural complex of anthraquinone glucosides found in senna, isolated from Cassia acutifolia or Cassia angustifolia as calcium salts. It is a brownish powder. Soluble 1 in 35 of water, 1 in 2100 of alcohol, 1 in 3700 of chloroform, and 1 in 6100 of ether. A 10% solution in water has a pH of 6.3 to 7.3. Store at a temperature of 20° to 25°. Protect from moisture and from light.

Adverse Effects

Senna may cause mild abdominal discomfort such as colic or cramps. Prolonged use or overdosage can result in diarrhoea with excessive loss of water and electrolytes, particularly potassium there is also the possibility of developing an atonic non-functioning colon. Anthraquinone derivatives may colour the urine yellowish-brown at acid pH, and red at alkaline pH. Reversible melanosis coli has been reported following chronic use.

Abuse. Prolonged use or abuse of senna laxatives has been associated with finger clubbing, hypokalaemia and tetany, hypertrophic osteoarthropathy, intermittent urinary excretion of aspartylglucosamine, hypogammaglobulinaemia, reversible cachexia, and hepatitis or hepatic failure. In one case, nephrocalcinosis was attributed to hypercalcaemia caused by excessive ingestion of calcium sennosides.

Effects on the liver. Hepatitis has been reported in a patient drinking herbal tea containing senna. The patient was found to be a poor metaboliser for hepatic detoxification reactions the authors cautioned against even small doses of herbal preparations in such patients.

Hepatitis and hepatic failure have also been reported after abuse of senna laxatives, see Abuse, above.

Hypersensitivity. Hypersensitivity reactions manifesting as asthma and rhinoconjunctivitis have been reported in those manufacturing or dispensing senna products. However, a study of 125 workers involved in the manufacture of laxatives found only 4 cases of occupational asthma, although sensitisation to senna or ispaghula dust was present in 18 and 9 of the workers respectively, and other airway, eye, and skin symptoms were relatively frequent.

A 2-year history of pruritic scaly erythematous plaques on the palmoplantar surfaces was reported by a patient who had taken a sennoside laxative for 20 years. The lesions subsided over about 6 weeks on stopping the drug, and reappeared over the course of 8 weeks on restarting sennoside. However, patch testing and lymphocyte stimulation tests for sennoside were negative.

Precautions

Senna should not be given to patients with nausea or vomiting, undiagnosed abdominal pain, or intestinal obstruction care should also be taken in patients with inflammatory bowel disease. Prolonged use should generally be avoided.

Although anthraquinone derivatives may be distributed into breast milk the concentration achieved after usual maternal dosage is thought to be insufficient to affect the nursing infant (see also below).

Breast feeding. No adverse effects have been seen in breastfed infants whose mothers were receiving senna, and the American Academy of Pediatrics considers that it is therefore usually compatible with breast feeding.

Colonic perforation. There were early reports of colonic perforation with faecal peritonitis, in one case fatal, after use of a senna preparation containing total sennosides 142 mg for bowel preparation before barium enema. In 1985, the strength of the UK preparation was halved to contain 72 mg of total sennosides it was subsequently withdrawn, although a similar preparation, at the higher strength, remains available in some countries. To reduce the risk of colonic perforation, patients with suspected stricture, inflammatory bowel disease, or impending obstruction should not receive a bowel stimulant.

Pharmacokinetics

There is some absorption of anthraquinone laxatives after oral doses. Absorbed anthraquinones are metabolised in the liver. Unabsorbed senna is hydrolysed in the colon by bacteria to release the active free antnraquinones. Anthraquinone s are excreted in urine and faeces and distributed into breast milk.

Uses and Administration

Senna is an anthraquinone stimulant laxative that is used to treat constipation and for bowel evacuation before investigational procedures or surgery. The active antnraquinones are liberated into the colon from the sennoside glycosides by colonic bacteria and an effect usually occurs within 6 to 12 hours of an oral dose.

For constipation, senna is usually given as tablets, granules, or syrup. In some countries it is available as suppositories. In the UK, doses of senna preparations are usually expressed in terms of total sennosides calculated as sennoside B. The usual adult oral dose is 15 to 30 mg as a single dose at bedtime. (For doses in children see Administration in Children, below.) In the USA, the usual adult dose is 15 to 30 mg once or twice daily, expressed in terms of total sennosides. For bowel evacuation before investigational procedures, a dose of 105 to 157.5 mg of sennosides may be given orally as a liquid preparation on the day before the procedure (but see Colonic Perforation under Precautions, above).

The purified sennosides (sennosides A and B), and their calcium salts (calcium sennoside A and calcium sennoside B) are used similarly to senna.

Homoeopathy. Senna leaf has been used in homoeopathic medicines under the following names: Senna Senna folium.

Administration in children. In the UK, the following oral doses of sennosides are licensed for use for constipation in children:

• aged 2 to 6 years: 3.75 to 7.5 mg once daily in the morning

• aged 6 to 12 years: 7.5 to 15 mg once daily at night or in the morning

• 12 years and over: 15 to 30 mg once daily, usually at bedtime In addition, although not licensed for use in children under 2 years, the BNFC allows for an oral dose of syrup (containing sennosides 7.5 mg per 5 mL) of 0.5 mL/kg (to a maximum of 2.5 mL) once daily in those aged 1 month to 2 years.
