For the full list of excipients, see section 6.1.

3 PHARMACEUTICAL FORM

Capsules, hard.

500 mg:

White capsule approximately 9 x 23 mm.

4 CLINICAL PARTICULARS

4.1 Therapeutic indications

For the treatment of primary biliary cholangitis (PBC), provided there is no decompensated hepatic cirrhosis.

For the dissolution of cholesterol gallstones in the gall bladder. The gallstones must not show as shadows on X-ray images and should not exceed 15 mm in diameter. The gall bladder must be functioning despite the gallstone(s).

Paediatric population:

Hepatobiliary disorders associated with cystic fibrosis in children aged 6 to 18 years.

4.2 Posology and method of administration

There are no age restrictions on the use of Ursodeoxycholic Acid Capsules in the treatment of PBC and for the dissolution of radiolucent gallstones.

Depending on the body weight of the patient, additional co-prescription of a lower strength containing 250 mg ursodeoxycholic acid may be necessary to achieve the recommended dosage.

For patients weighing less than 47 kg or patients who are unable to swallow Ursodeoxycholic Acid Capsules, other formulations with ursodeoxycholic acid (e.g. oral suspension) are available.

The following daily dose is recommended for the various indications:

For the treatment of primary biliary cholangitis (PBC)

The daily dose depends on body weight, and ranges from 14 ± 2 mg of UDCA per kg of body weight.

For the first 3 months of treatment, Ursodeoxycholic Acid Capsules should be taken in divided doses over the day. With improvement of the liver values the dose may be taken once daily in the evening.

The capsules should be swallowed whole with some liquid. Care should be taken to ensure that they are taken regularly.

The use of ursodeoxycholic acid in PBC may be continued indefinitely.

For dissolution of cholesterol gallstones:

Approximately 10 mg of UDCA per kg of body weight, equivalent to:

The capsules should be swallowed whole with some liquid. Care should be taken to ensure that they are taken regularly.

Treatment of gallstones using ursodeoxycholic acid requires a functioning gallbladder.

The time required for dissolution of gallstones is generally 6-24 months, depending on the stone size and composition. If there is no reduction in the size of the gall stones after 12 months, the therapy should not be continued.

The likelihood of recurrence of gallstones after dissolution by bile acid treatment has been estimated as up to 50% at 5 years. The efficiency of Ursodeoxycholic Acid Capsules in treating radio-opaque or partially radio-opaque gallstones has not been tested but these are generally thought to be less soluble than radiolucent stones. Non-cholesterol stones account for 10-15% of radiolucent stones and may not be dissolved by bile acids.

Older people

In both indications there is no evidence to suggest that any alteration in the adult dose is needed but the relevant precautions should be taken into account.

Paediatric population

Both indications are very rare in children and adolescents. Therefore there is no adequate data on the efficacy and safety in this population.

The administration of Ursodeoxycholic Acid Capsules is based on body weight and the medical condition.

For the treatment of hepatobiliary disorders associated with cystic fibrosis

Paediatric population

Children with cystic fibrosis aged 6 to 18 years:

20 mg/kg/day in 2-3 divided doses, with a further increase to 30 mg/kg/day if necessary.

4.3 Contraindications

Ursodeoxycholic Acid Capsules should not be used in patients with:

• Acute inflammation of the gall bladder or biliary tract
• Occlusion of the biliary tract (occlusion of the common bile duct or a cystic duct)
• Frequent episodes of biliary colic
• Radio-opaque calcified gallstones
• Impaired contractility of the gall bladder

• Hypersensitivity to bile acids or to any excipients of the formulation

  • Unsuccessful portoenterostomy or without recovery of good bile flow in children with biliary atresia.

When used in hepatobiliary disorders associated with cystic fibrosis in children aged 6 to 18 years:

• Unsuccessful portoenterostomy or without recovery of good bile flow in children with biliary atresia.

4.4 Special warnings and precautions for use

Ursodeoxycholic Acid Capsules should be taken under medical supervision.

During the first 3 months of treatment, liver function parameters ASAT (SGOT), ALAT (SGPT) and γ-GT should be monitored by the physician every 4 weeks, thereafter every 3 months. Apart from allowing for identification of responders and non-responders in patients being treated for PBC, this monitoring would also enable early detection of potential hepatic deterioration, particularly in patients with advanced stage PBC.

When used for treatment of advanced stage of primary biliary cholangitis:

In very rare cases decompensation of hepatic cirrhosis has been observed, which partially regressed after the treatment was discontinued.

In patients with PBC, in rare cases the clinical symptoms may worsen at the beginning of treatment, e.g. the itching may increase. In this case the dose should be reduced to 250 mg daily, and then gradually increased to the recommended dose described in section 4.2.

If diarrhoea occurs, the dose must be reduced and in cases of persistent diarrhoea, the therapy should be discontinued.

When used for dissolution of cholesterol gallstones:

In order to assess therapeutic progress and for timely detection of any calcification of the gallstones, depending on stone size, the gall bladder should be visualised (oral cholecystography) with overview and occlusion views in standing and supine positions (ultrasound control) 6-10 months after the beginning of treatment.

If the gall bladder cannot be visualised on X-ray images, or in cases of calcified gallstones, impaired contractility of the gall bladder or frequent episodes of biliary colic, Ursodeoxycholic Acid Capsules should not be used.

Female patients taking Ursodeoxycholic Acid Capsules for dissolution of gallstones should use an effective non-hormonal contraception since hormonal contraceptives may increase biliary lithiasis (see section 4.5 and 4.6).

4.5 Interaction with other medicinal products and other forms of interaction

Ursodeoxycholic Acid Capsules should not be administered concomitantly with colestyramine, colestipol or antacids containing aluminium hydroxide and/or smectite (aluminium oxide), because these preparations bind UDCA in the intestine and thereby inhibit its absorption and efficacy. Should the use of a preparation containing one of these substances be necessary, it must be taken at least 2 hours before or after Ursodeoxycholic Acid Capsules.

In isolated cases Ursodeoxycholic Acid Capsules can reduce the absorption of ciprofloxacin.

In a clinical study in healthy volunteers concomitant use of UDCA (500mg/day) and rosuvastatin (20mg/day) resulted in slightly elevated plasma levels of rosuvastatin. The clinical relevance of this interaction also with regard to other statins is unknown.

UDCA has been shown to reduce plasma peak concentrations C_max and area under the curve (AUC) of the calcium antagonist nitrendipine in healthy volunteers. Close monitoring of the outcome of concurrent use of nitrendipine and UDCA is recommended. An increase of the dose of nitrendipine may be necessary. An interaction with a reduction of the therapeutic effect of dapsone was also reported. These observations together with in vitro findings could indicate a potential for UDCA to induce cytochrome P450 3A enzymes. Induction has, however, not been observed in a well-designed interaction study with budesonide, which is a known cytochrome P450 3A substrate.

Oestrogenic hormones and blood cholesterol lowering agents such as clofibrate increase hepatic cholesterol secretion and may therefore encourage biliary lithiasis, which is a counter-effect to UDCA used for dissolution of gallstones.

4.6 Fertility, pregnancy and lactation

Animal studies did not show an influence of UDCA on fertility (see section 5.3). Human data on fertility effects following treatment with UDCA are not available.

Pregnancy

There are no or limited amounts of data from the use of UDCA in pregnant women. Studies in animals have shown reproductive toxicity during the early phase of gestation (see section 5.3). Ursodeoxycholic Acid Capsules must not be used during pregnancy unless clearly necessary.

Women of childbearing potential

Women of childbearing potential should be treated only if they use reliable contraception: non-hormonal or low-oestrogen oral contraceptive measures are recommended. However, in patients taking Ursodeoxycholic Acid Capsules for dissolution of gallstones, effective non-hormonal contraception should be used, since hormonal oral contraceptives may increase biliary lithiasis. The possibility of a pregnancy must be excluded before beginning treatment.

Breastfeeding

According to few documented cases of breastfeeding women milk levels of UDCA are very low and probably no adverse reactions are to be expected in breastfed infants.

4.7 Effects on ability to drive and use machines

Ursodeoxycholic Acid Capsules have no or negligible influence on the ability to drive and use machines.

4.8 Undesirable effects

The evaluation of undesirable effects is based on the following frequency data:

Very common (≥1/10)

Common (≥1/100 to < 1/10)

Uncommon (≥1/1,000 to < 1/100)

Rare (≥1/10,000 to < 1/1,000)

Very rare (< 1/10,000)

Not known (cannot be estimated from available data)

¹Observed during therapy of the advance stages of PBC and which partially regressed after treatment was discontinued.

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 Yellow Card Scheme, website: https://yellowcard.mhra.gov.uk/ or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9 Overdose

Diarrhoea may occur in cases of overdose. In general, other symptoms of overdose are unlikely because the absorption of UDCA decreases with increasing dose and therefore more is excreted with the faeces.

No specific counter-measures are necessary and the consequences of diarrhoea should be treated symptomatically with restoration of fluid and electrolyte balance.

Additional information regarding special populations

Long-term, high-dose UDCA therapy (28-30 mg/kg/day) in patients with primary sclerosing cholangitis (off-label use) was associated with higher rates of serious adverse events.

5 PHARMACOLOGICAL PROPERTIES

5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Bile acid preparations, ATC code: A05AA02.

UDCA is a bile acid which effects a reduction in cholesterol in biliary fluid primarily by dispersing the cholesterol and forming a liquid-crystal phase.

Cystric fibrosis - Paediatric population:

From clinical reports long-term experience up to 10 years and more is available with UDCA treatment in paediatric patients suffering from cystic fibrosis associated hepatobiliary disorders (CFAHD). There is evidence that treatment with UDCA can decrease bile duct proliferation, halt progression of histological damage and even reverse hepatobiliary changes if given at early stage of CFAHD. Treatment with UDCA should be started as soon as the diagnosis of CFAHD is made in order to optimise treatment effectiveness.

5.2 Pharmacokinetic properties

UDCA occurs naturally in the body. When given orally it is rapidly and completely absorbed. It is 96-98% bound to plasma proteins and efficiently extracted by the liver and excreted in the bile as glycine and taurine conjugates. In the intestines some of the conjugates are deconjugated and reabsorbed. The conjugates may also be dehyrodylated to lithocholic acid, part of which is absorbed, sulphated by the liver and excreted via the biliary tract.

5.3 Preclinical safety data

1. a) Acute toxicity

Acute toxicity studies in animals have not revealed any toxic damage.

1. b) Chronic toxicity

Subchronic toxicity studies in monkeys showed hepatotoxic effects in the groups given high doses, including functional changes (e.g. liver enzyme changes) and morphological changes such as bile duct proliferation, portal inflammatory foci and hepatocellular necrosis. These toxic effects are most likely attributable to lithocholic acid, a metabolite of UDCA, which in monkeys – unlike humans – is not detoxified. Clinical experience confirms that the described hepatotoxic effects are of no apparent relevance in humans.

1. c) Carcinogenic and mutagenic potential

Long-term studies in mice and rats revealed no evidence of UDCA having carcinogenic potential. In vitro and in vivo genetic toxicology tests with UDCA were negative. The tests with UDCA revealed no relevant evidence of a mutagenic effect.

1. d) Toxicity to reproduction

In studies in rats, tail malformations occurred after a dose of 2000 mg per kg of body weight. In rabbits, no teratogenic effects were found, although there were embryotoxic effects (from a dose of 100 mg per kg of body weight). UDCA had no effect on fertility in rats and did not affect peri-/post-natal development of the offspring
