What is Loprid?

Loprid slows the rhythm of digestion so that the small intestines have more time to absorb fluid and nutrients from the foods you eat.

Loprid is used to treat diarrhea. Loprid is also used to reduce the amount of stool in people who have an ileostomy (re-routing of the bowel through a surgical opening in the stomach).

Loprid may also be used for purposes not listed in this medication guide.

Loprid indications

infoAn indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

Uses of Loprid in details

infoThere are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.

This medication is used to treat sudden diarrhea (including traveler's diarrhea). It works by slowing down the movement of the gut. This decreases the number of bowel movements and makes the stool less watery. Loprid is also used to reduce the amount of discharge in patients who have had an ileostomy. It is also used to treat ongoing diarrhea in people with inflammatory bowel disease.

Loprid treats only the symptoms, not the cause of the diarrhea (e.g., infection). Treatment of other symptoms and the cause of the diarrhea should be determined by your doctor.

Do not use in children younger than 6 years unless directed by your doctor. This medication should not be used in infants younger than 24 months.

How to use Loprid (Loprid)

If you are using the over-the-counter product to self-treat, read all the directions on the product package before taking this medication. If your doctor has prescribed this medication, follow your doctor's directions and the directions on your prescription label.

Take this medication by mouth, usually after each loose stool or as directed by your doctor. Shake the bottle well before each use. Measure each dose carefully using the attached measuring cup. Do not use a household spoon since you may not get the correct dose.

The dosage is based on your condition and response to treatment. In children, dosage is also based on age and weight. Adults should not use more than 8 milligrams in 24 hours if self-treating, or 16 milligrams in 24 hours if under a doctor's direction.

Improper use of this medication (overuse or abuse) - or use with certain other medications - may cause serious harm, such as fast/irregular heartbeat or death. Do not increase your dose, take it more often, or use it for longer than directed. Be sure to tell your doctor or pharmacist about all the products you use (including prescription, nonprescription, and herbal products).

Diarrhea can cause a serious loss of body water (dehydration). Drink plenty of fluids and minerals (electrolytes) to replace what is lost. Tell your doctor right away if you develop signs of dehydration (e.g., extreme thirst, decreased urination, muscle cramps, weakness, fainting). You may also need to change to a bland diet during this time to reduce irritation to your stomach/intestines. Consult your doctor or pharmacist for more information.

Tell your doctor if your diarrhea does not improve after 2 days, if your condition worsens, or if you develop new symptoms. If you develop blood in the stool, fever, or an uncomfortable fullness/swelling of the stomach/abdomen, or if you think you may have a serious medical problem, seek immediate medical attention.

If you are taking this medication under your doctor's direction for ongoing diarrhea, tell your doctor if your diarrhea continues after 10 days of treatment.

Loprid description

sponsored

One of the long-acting synthetic antidiarrheals; it is not significantly absorbed from the gut, and has no effect on the adrenergic system or central nervous system, but may antagonize histamine and interfere with acetylcholine release locally. [PubChem]

Loprid dosage

(1 capsule = 2 mg)

Patients should receive appropriate fluid and electrolyte replacement as needed.

Acute Diarrhea

Adults: The recommended initial dose is 4mg (two capsules) followed by 2 mg (one capsule) after each unformed stool. Daily dose should not exceed 16mg (eight capsules). Clinical improvement is usually observed within 48 hours.

Children: In children 2 to 5 years of age (20 kg or less), the non-prescription liquid formulation (Loprid® (Loprid hcl) A-D 1 mg/5 mL) should be used; for ages 6 to 12, either Loprid® (Loprid hcl) Capsules or Loprid® (Loprid hcl) A-D Liquid may be used. For children 2 to 12 years of age, the following schedule for capsules or liquid will usually fulfill initial dosage requirements:

Recommended First Day Dosage Schedule

Two to five years: 1 mg t.i.d. (3mg daily dose) (13 to 20 kg) Six to eight years: 2 mg b.i.d. (4mg daily dose) (20 to 30 kg) Eight to twelve years: 2mg t.i.d. (6mg daily dose) (greater than 30 kg)

Recommended Subsequent Daily Dosage

Following the first treatment day, it is recommended that subsequent Loprid® (Loprid hcl) doses (1 mg/10 kg body weight) be administered only after a loose stool. Total daily dosage should not exceed recommended dosages for the first day.

Chronic Diarrhea

Children: Although Loprid® (Loprid hcl) has been studied in a limited number of children with chronic diarrhea; the therapeutic dose for the treatment of chronic diarrhea in a pediatric population has not been established.

Adults: The recommended initial dose is 4 mg (two capsules) followed by 2 mg (one capsule) after each unformed stool until diarrhea is controlled, after which the dosage of Loprid® (Loprid hcl) should be reduced to meet individual requirements. When the optimal daily dosage has been established, this amount may then be administered as a single dose or in divided doses.

The average daily maintenance dosage in clinical trials was 4 to 8 mg (two to four capsules). A dosage of 16 mg (eight capsules) was rarely exceeded. If clinical improvement is not observed after treatment with 16 mg per day for at least 10 days, symptoms are unlikely to be controlled by further administration. Loprid® (Loprid hcl) administration may be continued if diarrhea cannot be adequately controlled with diet or specific treatment.

Children under 2 Years

The use of Loprid (Loprid hcl) in children under 2 years is not recommended. There have been rare reports of paralytic ileus associated with abdominal distention. Most of these reports occurred in the setting of acute dysentery, overdose, and with very young children less than two years of age.

Elderly

No formal pharmacokinetic studies were conducted in elderly subjects. However, there were no major differences reported in the drug disposition in elderly patients with diarrhea relative to young patients. No dosage adjustment is required for the elderly.

Renal Impairment

No pharmacokinetic data are available in patients with renal impairment. Since the metabolites and the unchanged drug are mainly excreted in the feces, no dosage adjustment is required for patients with renal impairment.

Hepatic Impairment

Although no pharmacokinetic data are available in patients with hepatic impairment, Loprid (Loprid hcl) should be used with caution in such patients because of reduced first pass metabolism..

How supplied

Capsules - each capsule contains 2 mg of Loprid hydrochloride. The capsules have a light green body and a dark green cap with "JANSSEN" imprinted on one segment and "Loprid" on the other segment. Loprid® (Loprid hcl) capsules are supplied in bottles of 100.

Nonclinical data have shown that Loprid is a P-glycoprotein substrate. Concomitant administration of Loprid (16 mg single dose) with a 600 mg single dose of either quinidine, or ritonavir, both of which are P-glycoprotein inhibitors, resulted in a 2- to 3- fold increase in Loprid plasma levels. Due to the potential for enhanced central effects when Loprid is coadministered with quinidine and with ritonavir, caution should be exercised when Loprid is administered at the recommended dosages (2 mg, up to 16 mg maximum daily dose) with P-glycoprotein inhibitors.

When a single 16-mg dose of Loprid is coadministered with a 600 mg single dose of saquinavir, Loprid decreased saquinavir exposure by 54%, which may be of clinical relevance due to reduction of therapeutic efficacy of saquinavir. The effect of saquinavir on Loprid is of less clinical significance. Therefore, when Loprid is given with saquinavir, the therapeutic efficacy of saquinavir should be closely monitored.

Post -marketing experience

The following adverse events have been reported:

Skin and subcutaneous tissue disorders

Rash, pruritus, urticaria, angioedema, and extremely rare cases of bullous eruption including erythema multiforme, Stevens-Johnson syndrome and Toxic Epidermal Necrolysis have been reported with use of Loprid (Loprid hcl).

Immune system disorders

Isolated occurrences of allergic reactions and in some cases severe hypersensitivity reactions including anaphylactic shock and anaphylactoid reactions have been reported with the use of Loprid (Loprid hcl).

Gastrointestinal disorders

Dry mouth, abdominal pain, distention or discomfort, nausea, vomiting, flatulence, dyspepsia, constipation, paralytic ileus, megacolon, including toxic megacolon.

Renal and urinary disorders

Urinary retention

Nervous system disorders

Drowsiness, dizziness

General disorders and administrative site conditions

Tiredness

A number of the adverse events reported during the clinical investigations and post- marketing experience with Loprid are frequent symptoms of the underlying diarrheal syndrome (abdominal pain/discomfort, nausea, vomiting, dry mouth, tiredness, drowsiness, dizziness, constipation, and flatulence). These symptoms are often difficult to distinguish from undesirable drug effects.

Drug Abuse And Dependence

Abuse

A specific clinical study designed to assess the abuse potential of Loprid at high doses resulted in a finding of extremely low abuse potential.

Dependence

Studies in morphine-dependent monkeys demonstrated that Loprid hydrochloride at doses above those recommended for humans prevented signs of morphine withdrawal. However, in humans, the naloxone challenge pupil test, which when positive indicates opiate-like effects, performed after a single high dose, or after more than two years of therapeutic use of Loprid® (Loprid hydrochloride), was negative.

Orally administered Loprid® (Loprid hcl) (Loprid formulated with magnesium stearate) is both highly insoluble and penetrates the CNS poorly.
