What is Glyrx-Pf?

From the FDA label:GLYRX ® -PF is a synthetic anticholinergic agent. It is intended for intramuscular or intravenous administration. Each 1 mL of GLYRX ® -PF contains 0.2 mg of glycopyrrolate, water for injection, sodium chloride as a tonicity agent, and hydrochloric acid or sodium hydroxide as pH adjusters. GLYRX ® -PF is preservative free. Glycopyrrolate is a quaternary ammonium salt with the following chemical name: ( RS )-[3-( SR )-Hydroxy-1,1-dimethylpyrrolidinium bromide] α-cyclopentylmandelate. The molecular formula is C 19 H 28 BrNO 3 and the molecular weight is 398.34. Glycopyrrolate structural formula is as follows: Glycopyrrolate occurs as a white, odorless, crystalline powder. It is soluble in water and alcohol, and practically insoluble in chloroform and ether. It is completely ionized at physiological pH values. GLYRX ® -PF is a clear, colorless, sterile liquid with a pH of 2.0 – 3.0. The partition coefficient of Glycopyrrolate in n-octanol/water system is 0.304 (log 10 P = -1.52) at ambient room temperature (24°C). Structure

Side effects

The following adverse reactions were identified in clinical studies or postmarketing reports. Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Adverse reactions to anticholinergics include xerostomia (dry mouth); urinary hesitancy and retention; blurred vision and photophobia due to mydriasis (dilation of the pupil); cycloplegia; increased ocular tension; tachycardia; palpitation; decreased sweating; loss of taste; headache; nervousness; drowsiness; weakness; dizziness; insomnia; nausea; vomiting; impotence; suppression of lactation; constipation; bloated feeling; severe allergic reactions including anaphylactic/anaphylactoid reactions; hypersensitivity; urticaria, pruritus, dry skin, and other dermal manifestations; some degree of mental confusion and/or excitement, especially in elderly persons. The following adverse reactions have been reported from post-marketing experience with glycopyrrolate: malignant hyperthermia; cardiac arrhythmias (including bradycardia, ventricular tachycardia, ventricular fibrillation); cardiac arrest; hypertension; hypotension; seizures; and respiratory arrest. Post-marketing reports have included cases of heart block and QTc interval prolongation associated with the combined use of…

Warnings

Important safety information

Precipitation of Acute Glaucoma : Glycopyrrolate may cause mydriasis and increase intraocular pressure in patients with glaucoma. Advise patients with glaucoma to promptly seek medical care if they experience symptoms of acute angle closure glaucoma. ( 5.1 ) • Drowsiness or Blurred Vision : May cause drowsiness or blurred vision. Advise patients not to drive or perform hazardous work until resolved. ( 5.2 ) • Heat Prostration : Advise patients to avoid exertion and high environmental temperatures after receiving GLYRX ® -PF. ( 5.3 ) • Intestinal Obstruction : Diarrhea may be an early symptom of incomplete intestinal obstruction. Avoid use in patients with diarrhea and ileostomy or colostomy. ( 5.4 ) • Tachycardia : Increase in heart rate may occur. Use with caution in patients with coronary artery disease, congestive heart failure, cardiac arrhythmias, hypertension, or hyperthyroidism. ( 5.5 ) 5.1 Precipitation of Acute Glaucoma Glycopyrrolate may cause mydriasis and increase intraocular pressure in patients with glaucoma. Advise patients with glaucoma to promptly seek medical care in the event that they experience symptoms of acute angle closure glaucoma (pain and reddening of the eyes, accompanied by dilated pupils). 5.2 Drowsiness or Blurred Vision GLYRX ® -PF may cause drowsiness or blurred vision. Warn patients not to participate in activities requiring mental alertness, such as operating a motor vehicle or other machinery, or performing hazardous work, until these issues resolve. 5.3 Heat Prostration In the presence of fever, high environmental temperature, and/or during physical exercise, heat prostration can occur with use of anticholinergic agents including GLYRX ® -PF (due to decreased sweating), particularly in children and the elderly. Advise patients to avoid exertion and high environmental temperature after receiving GLYRX ® -PF. 5.4 Intestinal Obstruction Diarrhea may be an early symptom of incomplete intestinal obstruction, especially in patients with ileostomy or colostomy. In this instance treatment with GLYRX ® -PF is inappropriate and possibly harmful. Avoid use in patients with these conditions. 5.5 Tachycardia Investigate any tachycardia before giving GLYRX ® -PF because an increase in the heart rate may occur. Use with caution in patients with coronary artery disease, congestive heart failure, cardiac arrhythmias, hypertension, or hyperthyroidism. 5.6 Risk of Use in Patients with Renal Impairment Renal elimination of glycopyrrolate may be severely impaired in patients with renal failure. Dosage adjustments may be necessary in this population [ see Clinical Pharmacology ( 12.3 ) ]. 5.7 Autonomic Neuropathy, Hepatic Disease, Ulcerative Colitis, Prostatic Hypertrophy, or Hiatal Hernia Use GLYRX ® -PF with caution in the elderly and in all patients with autonomic neuropathy, hepatic disease, ulcerative colitis, prostatic hypertrophy, or hiatal hernia, because anticholinergic drugs may aggravate these conditions. Consider dose reduction and closely monitor the elderly and patients with autonomic neuropathy, hepatic disease, ulcerative colitis, prostatic hypertrophy, or hiatal hernia. 5.8 Delayed Gastric Emptying/Gastric Stasis The use of anticholinergic drugs, including GLYRX ® -PF, in the treatment of peptic ulcer may produce a delay in gastric emptying/gastric stasis. Monitor patients for symptoms such as vomiting, dyspepsia, early satiety, abdominal distention, and increased abdominal pain. Discontinue GLYRX ® -PF treatment if these symptoms develop or worsen on treatment. 5.9 Light Sensitivity Patients may experience sensitivity of the eyes to light. Advise patients to protect their eyes from light after receiving GLYRX ® -PF.

Who should not take Glyrx-Pf

GLYRX ® -PF is contraindicated in: • patients with known hypersensitivity to glycopyrrolate or any of its inactive ingredients. • peptic ulcer patients with the following concurrent conditions: glaucoma; obstructive uropathy (for example, bladder neck obstruction due to prostatic hypertrophy); obstructive disease of the gastrointestinal tract (as in achalasia, pyloroduodenal stenosis, etc.); paralytic ileus, intestinal atony of the elderly or debilitated patient; unstable cardiovascular status in acute hemorrhage; severe ulcerative colitis; toxic megacolon complicating ulcerative colitis; myasthenia gravis. • Known hypersensitivity to glycopyrrolate or any of its inactive ingredients. ( 4 ) • Peptic ulcer patients with glaucoma; obstructive uropathy; obstructive disease of the gastrointestinal tract; paralytic ileus, intestinal atony of the elderly, or debilitated patient; unstable cardiovascular status in acute hemorrhage; severe ulcerative colitis; toxic megacolon; complicating ulcerative colitis; myasthenia gravis. ( 4 )

Overdose — what happens if you take too much

To combat peripheral anticholinergic effects, a quaternary ammonium anticholinesterase such as neostigmine methylsulfate (which does not cross the blood-brain barrier) may be given intravenously in increments of 0.25 mg in adults. This dosage may be repeated every five to ten minutes until anticholinergic overactivity is reversed or up to a maximum of 2.5 mg. Proportionately smaller doses should be used in pediatric patients. Indication for repetitive doses of neostigmine should be based on close monitoring of the decrease in heart rate and the return of bowel sounds. If CNS symptoms (e.g., excitement, restlessness, convulsions, psychotic behavior) occur, physostigmine (which does cross the blood–brain barrier) may be used. Physostigmine 0.5 to 2 mg should be slowly administered intravenously and repeated as necessary up to a total of 5 mg in adults. Proportionately smaller doses should be used in pediatric patients. To combat hypotension, administer IV fluids and/or pressor agents along with supportive care. Fever should be treated symptomatically. Following overdosage, a curare-like action may occur, i.e., neuromuscular blockade leading to muscular weakness and possible paralysis. In the event of a curare-like effect on respiratory muscles, artificial respiration should be instituted and maintained until effective respiratory action returns.

Interactions

The concurrent use of GLYRX ® -PF with other anticholinergics or medications with anticholinergic activity, such as phenothiazines, antiparkinson drugs, or tricyclic antidepressants, may intensify the antimuscarinic effects and result in an increase in anticholinergic side effects. Concomitant administration of GLYRX ® -PF and potassium chloride in a wax matrix may increase the severity of potassium chloride-induced gastrointestinal lesions as a result of a slower gastrointestinal transit time. Other anticholinergics or drugs with anticholinergic activity : May intensify the antimuscarinic effects and result in an increase in anticholinergic side effects. ( 7 ) Potassium Chloride in a Wax Matrix : May increase severity of potassium chloride-induced gastrointestinal lesions. ( 7 )

Frequently asked questions

What does Glyrx-Pf treat?
Glyrx-Pf (Glycopyrrolate) may be used to treat hyperhidrosis, drug-induced abnormalities, peptic ulcer, respiratory tract diseases, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.
How does Glyrx-Pf work?
Glyrx-Pf is a anticholinergic. Anticholinergic drugs block acetylcholine, the chemical messenger of the body's "rest and digest" nervous system, by occupying its muscarinic receptors. This eases muscle spasms, dries up secretions, relaxes the bladder and airways, and speeds the heart, depending on the tissue.
How much does Glyrx-Pf cost?
Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $0.21 per ml, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins.
