Equipil D

Uses

Chlordiazepoxide is a benzodiazepine used to treat the withdrawal symptoms of acute alcoholism, to treat preoperative anxiety, and to treat anxiety over a short term period.

For the management of anxiety disorders or for the short-term relief of symptoms of anxiety, withdrawal symptoms of acute alcoholism, and preoperative apprehension and anxiety.

Dicycloverine is used for:

• Functional bowel/ irritable bowel syndrome
• Urinary incontinence secondary to unstable detrusor muscle

• Abdominal colic

Equipil D is also used to associated treatment for these conditions: Alcohol Withdrawal Syndrome, Anxiety, Anxiety Disorders, Depression, Peptic Ulcer Disease, Acute Anxiety, Pyschosomatic diseaseFunctional bowel syndrome, Irritable Bowel Syndrome (IBS), Gastrointestinal cramps caused by Gas

How Equipil D works

Chlordiazepoxide binds to stereospecific benzodiazepine (BZD) binding sites on GABA (A) receptor complexes at several sites within the central nervous system, including the limbic system and reticular formation. This results in an increased binding of the inhibitory neurotransmitter GABA to the GABA(A) receptor. BZDs, therefore, enhance GABA-mediated chloride influx through GABA receptor channels, causing membrane hyperpolarization. The net neuro-inhibitory effects result in the observed sedative, hypnotic, anxiolytic, and muscle relaxant properties.

Dicyclomine achieves its action partially through direct antimuscarinic activity of the M1, M3, and M2 receptors; and partially through antagonism of bradykinin and histamine. Dicyclomine non-competitively inhibits the action of bradykinin and histamine, resulting in direct action on the smooth muscle, and decreased strength of contractions seen in spasms of the ileum.

Toxicity

LD₅₀=537 mg/kg (Orally in rats). Signs of overdose include respiratory depression, muscle weakness, somnolence (general depressed activity).

Patients experiencing an overdose may present with headache, nausea, vomiting, blurred vision, dilated pupils, dizziness, dry mouth, difficulty swallowing, CNS stimulation, as well as hot, dry skin. Treat patients with gastric lavage, emetics, activated charcoal, sedatives for excitement, and a cholinergic agent if indicated.

The oral LD₅₀ in mice is 625mg/kg.

Precaution

Use with caution in patients with autonomic neuropathy, hepatic or renal disease, ulcerative colitis, coronary heart disease, congestive heart failure, cardiac tachyarrhythmia, known or suspected prostatic hypertrophy.

Interaction

The following agents may increase certain actions or side-effects of Dicycloverine-antiarrhythmic agents, antihistamines, antipsychotic agents, benzodiazepines, MAO inhibitors, narcotic analgesics, nitrates and nitrites, sympathomimetic agents, tricyclic antidepressants and other drugs having anticholinergic activity.

Volume of Distribution

The volume of distribution for a 20mg oral dose is 3.65L/kg.

Elimination Route

The bioavailability of dicyclomine has not been determined, though it is likely well absorbed as the primary route of elimination is in the urine. Dicyclomine has a T_max of 1-1.5h.

Half Life

24-48 hours

The mean plasma elimination half life is approximately 1.8 hours.

Clearance

Data regarding the clearance of dicyclomine is not readily available.

Elimination Route

Chlordiazepoxide is excreted in the urine, with 1% to 2% unchanged and 3% to 6% as conjugate.

Dicyclomine is 79.5% eliminated in the urine and 8.4% in the feces.

Pregnancy & Breastfeeding use

Pregnancy: Category B. Dicycloverine was neither teratogenic nor embryocidal in animal trial. It, like other drugs should be used during pregnancy only if clearly needed. There are no data on the secretion of this drug into breast milk. Dicycloverine should be used cautiously in case of lactating mother.

Contraindication

Dicycloverine is contraindicated in:

• Obstructive uropathy
• Obstructive disease of the gastrointestinal tract
• Severe ulcerative colitis
• Reflux esophagitis
• Unstable cardiovascular status in acute hemorrhage
• Glaucoma
• Myasthenia gravis
• Evidence of prior hypersensitivity to dicycloverine hydrochloride or other ingredients of this formulation
• Infants less than 6 months of age

Acute Overdose

Toxic reaction seldom occurs with dicycloverine. The signs and symptoms of overdosage are headache; nausea; vomiting; blurred vision; dilated pupils; hot, dry skin; dizziness; dryness of the mouth; difficulty in swallowing; and CNS stimulation.

Storage Condition
