Phenohytro Elixir - Clinical Pharmacology

This drug combination provides phenobarbital combined with belladonna alkaloids in a specific, fixed ratio to provide anticholinergic/antispasmodic action and mild sedation.

Phenobarbital is a barbiturate, nonselective central nervous system depressant. It is primarily used as a sedative hypnotic and also as an anticonvulsant in subhypnotic doses.

Atropine Sulfate, Hyoscyamine Sulfate, and Scopolamine are belladonna alkaloids classified as anticholinergic, antimuscarinic drugs. They act to inhibit muscarinic actions of acetylcholine at postganglionic parasympathetic neuron effector sites. These drugs are also used as antispasmodics due to their anticholinergic action. They produce the effect in the body of reduced muscle spasms in the digestive or urinary tract, and reduced fluid secretions from certain glands or organs.

Indications and Usage for Phenohytro Elixir

Based on the National Academy of Sciences-National Research Council's review of this drug and/or other information, FDA has classified the following indications as "possibly" effective: For use as adjunctive therapy in the treatment of irritable bowel syndrome (irritable colon, spastic colon, mucous colitis) and acute enterocolitis. May also be useful as adjunctive therapy in the treatment of duodenal ulcer.

IT HAS NOT BEEN SHOWN CONCLUSIVELY WHETHER ANTICHOLINERGIC / ANTISPASMODIC DRUGS AID IN THE HEALING OF A DUODENAL ULCER, DECREASE THE RATE OF RECURRENCES, OR PREVENT COMPLICATIONS.

Contraindications

PHENOHYTRO® ELIXIR is contraindicated in patients with known hypersensitivity to any of the ingredients. Phenobarbital is contraindicated in patients with acute intermittent porphyria and in those patients in which phenobarbital produces restlessness and/or excitement.

PHENOHYTRO® ELIXIR is also contraindicated in patients with glaucoma, obstructive uropathy; paralytic ileus; myasthenia gravis; intestinal atony; unstable cardiovascular status in acute hemorrhage; severe ulcerative colitis especially if complicated by toxic megacolon; hiatal hernia associated with reflux esophagitis; obstructive disease of the gastrointestinal tract; or severe ulcerative colitis.

Warnings

Heat prostration can occur with belladonna alkaloids in high temperatures.

Diarrhea may be an early symptom of incomplete intestinal obstruction, particularly in patients with ileostomy or colostomy. In this instance, treatment with this drug could be harmful.

PHENOHYTRO® ELIXIR may produce drowsiness and blurred vision. The patient should be warned about engaging in hazardous work or activities requiring mental alertness, such as operating a motor vehicle or other machinery.

Phenobarbital may decrease the effect of anticoagulants, and larger doses of the anticoagulant may be necessary for optimal effect. When phenobarbital is discontinued, the dose of the anticoagulant may have to be decreased.

Phenobarbital may be habit forming and should not be administered to patients who are susceptible to addiction or to those with a history of physical and/or psychological drug dependence.

Barbiturates should be used with caution in patients with hepatic dysfunction.

Precautions

GENERAL

Use with caution in patients with: autonomic neuropathy, hepatic or renal disease, hyperthyroidism, coronary heart disease, congestive heart failure, cardiac arrhythmias, tachycardia, and hypertension.

Belladonna alkaloids may produce a delay in gastric emptying (antral stasis), which would complicate the management of gastric ulcer.

Do not rely on the use of the drug in the presence of complication of biliary tract disease. Theoretically, a curare-like action may occur with overdosage.

CARCINOGENESIS, MUTAGENESIS, IMPAIRMENT OF FERTILITY

INFORMATION FOR PATIENTS

Practitioners should give the following information and instructions to patients:

  • Do not increase the dose of this drug without consulting a physician.
  • Do not share this medication with others.
  • The use of this product carries with it an associated risk of psychological and/or physical dependence.
  • The use of this product may impair mental and/or physical abilities required for the performance of potentially hazardous tasks such as driving or operating machinery.
  • Use of this product with alcohol may result in additional central nervous system depressant effects.
  • Tell your doctor or pharmacist if you also take antihistamines, anti-seizure drugs, medicine for sleep or anxiety, muscle relaxants, narcotic pain relievers, or psychiatric medicines.
  • This drug may increase the risk for heatstroke because it decreases sweating. Avoid becoming overheated in hot weather, saunas, and during exercise or other strenuous activity.

Adverse Reactions

Call your doctor for medical advice about side effects.

Adverse reactions associated with anticholinergics and/or anticonvulsants are: dry mouth; tachycardia; urinary hesitancy and retention; palpitation; blurred vision; prolonged pupil dilation; cycloplegia; increased ocular tension; loss of taste sense; headache; nervousness; drowsiness; weakness; dizziness; insomnia; nausea; vomiting; severe allergic reaction or drug idiosyncrasies, including anaphylaxis, hives and/or other dermal manifestations; decreased sweating; impotence; suppression of lactation; constipation; bloated feeling and musculoskeletal pain. Elderly patients may react with symptoms of excitement, agitation and drowsiness to even small doses of the drug. Phenobarbital may produce excitement in some patients, rather than a sedative effect. In patients habituated to barbiturates, abrupt withdrawal may produce delirium or convulsions.
