Chlordiazepoxide Hydrochloride and Clidinium Bromide

INDICATIONS AND USAGE: Chlordiazepoxide hydrochloride and clidinium bromide capsules are indicated to control emotional and somatic factors in gastrointestinal disorders. Chlordiazepoxide hydrochloride and clidinium bromide capsules may also be used as adjunctive therapy in the treatment of peptic ulcer and in the treatment of the irritable bowel syndrome (irritable colon, spastic colon, mucous colitis) and acute enterocolitis.

DOSAGE AND ADMINISTRATION: Recommended Dosage Because of the varied individual responses to tranquilizers and anticholinergics, the optimum dosage of chlordiazepoxide hydrochloride and clidinium bromide capsules, USP varies with the diagnosis and response of the individual patient. The dosage, therefore, should be individualized for maximum beneficial effects. The usual maintenance dose is 1 or 2 capsules, 3 or 4 times a day administered before meals and at bedtime. Recommended Geriatric Dosage Dosage should be limited to the smallest effective amount to preclude the development of ataxia, oversedation or confusion. The initial dose should not exceed 2 chlordiazepoxide hydrochloride and clidinium bromide capsules, USP capsules per day, to be increased gradually as needed and tolerated. Elderly patients have an increased risk of dose-related adverse reactions (see PRECAUTIONS ). Discontinuation or Dosage Reduction of chlordiazepoxide hydrochloride and clidinium bromide To reduce the risk of withdrawal reactions, use a gradual taper to discontinue chlordiazepoxide hydrochloride and clidinium bromide or reduce the dosage. If a patient develops withdrawal reactions, consider pausing the taper or increasing the dosage to the previous tapered dosage level. Subsequently decrease the dosage more slowly (see WARNINGS and DRUG ABUSE AND DEPENDENCE ).

CONTRAINDICATIONS: Chlordiazepoxide hydrochloride and clidinium bromide capsules are contraindicated in the presence of glaucoma (since the anticholinergic component may produce some degree of mydriasis) and in patients with prostatic hypertrophy and benign bladder neck obstruction. It is contraindicated in patients with known hypersensitivity to chlordiazepoxide hydrochloride and/or clidinium bromide.

ADVERSE REACTIONS: No side effects or manifestations not seen with either compound alone have been reported with the administration of chlordiazepoxide hydrochloride and clidinium bromide capsules. However, since chlordiazepoxide hydrochloride and clidinium bromide capsules contains chlordiazepoxide hydrochloride and clidinium bromide, the possibility of untoward effects which may be seen with either of these two compounds cannot be excluded. When chlordiazepoxide hydrochloride has been used alone the necessity of discontinuing therapy because of undesirable effects has been rare. Drowsiness, ataxia and confusion have been reported in some patients — particularly the elderly and debilitated. While these effects can be avoided in almost all instances by proper dosage adjustment, they have occasionally been observed at the lower dosage ranges. In a few instances syncope has been reported. Other adverse reactions reported during therapy with chlordiazepoxide hydrochloride include isolated instances of skin eruptions, edema, minor menstrual irregularities, nausea and constipation, extrapyramidal symptoms, as well as increased and decreased libido. Such side effects have been infrequent and are generally controlled with reduction of dosage. Changes in EEG patterns (low-voltage fast activity) have been observed in patients during and after chlordiazepoxide hydrochloride treatment. Blood dyscrasias, including agranulocytosis, jaundice and hepatic dysfunction have occasionally been reported during therapy with chlordiazepoxide hydrochloride. When chlordiazepoxide hydrochloride treatment is protracted, periodic blood counts and liver function tests are advisable. Adverse effects reported with use of chlordiazepoxide hydrochloride and clidinium bromide capsules are those typical of anticholinergic agents, i.e., dryness of the mouth, blurring of vision, urinary hesitancy and constipation. Constipation has occurred most often when chlordiazepoxide hydrochloride and clidinium bromide capsules therapy has been combined with other spasmolytic agents and/or a low residue diet.

Drug Interactions Opioids The concomitant use of benzodiazepines, including chlordiazepoxide hydrochloride, a component of chlordiazepoxide hydrochloride and clidinium bromide capsules, and opioids increases the risk of respiratory depression because of actions at different receptor sites in the CNS that control respiration. Benzodiazepines interact at GABA A sites and opioids interact primarily at mu receptors. When benzodiazepines and opioids are combined, the potential for benzodiazepines to significantly worsen opioid-related respiratory depression exists. Limit dosage and duration of concomitant use of chlordiazepoxide hydrochloride and clidinium bromide capsules and opioids, and follow patients closely for respiratory depression and sedation. Oral Anticoagulants Although clinical studies have not established a cause and effect relationship, physicians should be aware that variable effects on blood coagulation have been reported very rarely in patients receiving oral anticoagulants and chlordiazepoxide hydrochloride, a component of chlordiazepoxide hydrochloride and clidinium bromide capsules.

DESCRIPTION Chlordiazepoxide hydrochloride and clidinium bromide capsules, USP are a fixed-combination of chlordiazepoxide hydrochloride, a benzodiazepine, and clidinium bromide, an anticholinergic.

OVERDOSAGE Overdosage of chlordiazepoxide hydrochloride and clidinium bromide capsules, which contains a benzodiazepine (chlordiazepoxide hydrochloride) and an anticholinergic (clidinium bromide) may manifest signs and symptoms related to either of its components, although some effects such as altered levels of consciousness may be synergistic. Overdosage of benzodiazepines, such as chlordiazepoxide hydrochloride, is characterized by central nervous system depression ranging from drowsiness to coma. In mild to moderate cases, symptoms can include drowsiness, confusion, dysarthria, lethargy, hypnotic state, diminished reflexes, ataxia, and hypotonia. Rarely, paradoxical or disinhibitory reactions (including agitation, irritability, impulsivity, violent behavior, confusion, restlessness, excitement, and talkativeness) may occur. In severe overdosage cases, patients may develop respiratory depression and coma. Signs and symptoms of anticholinergic overdosage are related to excessive anti-muscarinic anticholinergic activity. Peripheral signs and symptoms may include dry mucous membranes and skin, flushing, tachycardia, hypertension, ileus, urinary retention, and mydriasis. Garbled speech is often pathognomonic. Central signs and symptoms may include agitation and delirium, seizures, and hyperthermia. Benzodiazepines are considered a first-line treatment for anticholinergic toxicity acting to treat mild to moderate agitation and prevent seizures. Overdosage of benzodiazepines in combination with other CNS depressants (including alcohol and opioids) may be fatal ( see WARNINGS, Dependence and Withdrawal Reactions ). Markedly abnormal (lowered or elevated) blood pressure, heart rate, or respiratory rate raise the concern that additional drugs and/or alcohol are involved in the overdosage. Anticholinergic drugs usually increase heart rate and blood pressure. In managing benzodiazepine overdosage, employ general supportive measures, including intravenous fluids, and airway management. Flumazenil, a specific benzodiazepine receptor antagonist is indicated for the complete or partial reversal of the sedative effects of benzodiazepines in the management of benzodiazepine overdosage. Use of flumazenil may increase the risk of seizures in mixed overdosage with drugs that may precipitate seizures, including anticholinergic medications. Benzodiazepines are used to treat agitated delirium from anticholinergic toxicity. Therefore flumazenil administration may worsen the anticholinergic delirium and should generally be avoided. Anticholinesterase inhibitors may reverse severe agitated delirium that is not controlled by benzodiazepines. They may also improve the airway and breathing in CNS depressed patients. Caution is warranted especially in mixed drug overdoses. Consider contacting a poison center (1-800-222-1222) or a medical toxicologist for overdosage management recommendations.
