What is Zyfrel

Hydrocodone

The Generic name of this drug

Treatment Summary

Hydrocodone is a pain medication derived from codeine. It is usually combined with acetaminophen to treat moderate to severe pain. In the past, it was often used as a cough suppressant, but it has been mostly replaced by dextromethorphan in current cough and cold medications. Hydrocodone's more powerful form, hydromorphone, is used for more severe pain and was approved by the FDA in 1943.

Effectiveness

How Zyfrel Affects Patients

Hydrocodone is a drug that blocks pain signals from being sent to the brain and spine, which reduces pain. It can also cause feelings of pleasure, shallow breathing, and drowsiness.

How Zyfrel works in the body

Hydrocodone works by attaching to two types of opioid receptors in the body. The first is the mu opioid receptor, and the second is the delta opioid receptor. When the receptors are activated, it causes a reaction in the body that reduces pain signals and suppresses the cough reflex. It also releases dopamine in the brain, which produces a feeling of pleasure. This can lead to addiction. Hydrocodone also reduces the GABAergic tone in certain parts of the brain, which can lead to sedation and respiratory depression. Finally, it can also activate inhibitory neurons in the spinal cord, further reducing pain signals.

When to interrupt dosage

The measure of Zyfrel is contingent upon the diagnosed condition, such as Coughing, Coughing and Chronic Pain. The amount of dosage changes, in accordance with the approach of delivery (e.g. Tablet, extended release - Oral or Tablet - Oral) specified in the table beneath.

Common Zyfrel Drug Interactions

Drug Name

Risk Level

Description

Astemizole

Major

The metabolism of Astemizole can be decreased when combined with Hydrocodone.

Azelastine

Major

Hydrocodone may increase the central nervous system depressant (CNS depressant) activities of Azelastine.

Cyclophosphamide

Major

The metabolism of Cyclophosphamide can be decreased when combined with Hydrocodone.

Eluxadoline

Major

The risk or severity of constipation can be increased when Hydrocodone is combined with Eluxadoline.

Enasidenib

Major

The metabolism of Enasidenib can be decreased when combined with Hydrocodone.

Zyfrel Toxicity & Overdose Risk

Taking too much hydrocodone can lead to serious side effects, such as trouble breathing, extreme drowsiness, low muscle tone, cold and clammy skin, small pupils, fluid in the lungs, slow heartbeat, low blood pressure, blocked airways, abnormal snoring, and death. If this happens, medical attention is necessary. Treatment may include giving oxygen and fluids through an IV, using drugs to maintain circulation, and using naloxone, an opioid antagonist, to reverse the drug's effects. Monitoring is still necessary after naloxone is administered as the opioid effects may return. In patients who are already opioid

SBS-147 Safety Study

18 - 55
All Sexes
Cypress, CA

This study is part of the HEAL Initiative supported by the NIH. The purpose of this study is to learn how safe the study drug, SBS-147, is and how people's bodies respond to and process it. Researchers will also look for any side effects that may occur when taking SBS-147. Some participants will receive SBS-147, and others will receive a placebo, which looks the same but does not contain any medicine. This helps researchers fairly compare results. The study includes two parts: Single-Dose Group, where Participants receive SBS-147 or placebo one time. Multiple-Dose Group, where Participants receive SBS-147 or placebo once or twice daily for 7 days.

Omeprazole + Lifestyle Therapy for Laryngopharyngeal Reflux

18 - 89
All Sexes
San Deigo, CA

The goal of this clinical trial is to learn if a mechanism guided strategy that utilizes a multidisciplinary approach to treat adults patients (age 18-89) with chronic throat symptoms who are undergoing clinical evaluation for laryngopharyngeal reflux (LPR) is more effective than the usual care strategy with proton pump inhibitor (PPI) therapy used in gastroenterology for these patients. The main question it aims to answer is: Will a greater proportion of the mechanism guided strategy participants achieve symptom response in comparison to the usual care strategy participants? If there is a comparison group: Researchers will compare the mechanism guided strategy to usual care strategy to see if treatment response differs between the groups. Participants will be be asked to do the following: * participate in an 8-week blinded study phase where they will be randomized to either 1) Mechanism Guided Strategy or 2) Usual Care Strategy * take an oral capsule daily (omeprazole 40mg or placebo) * come to 3 in-person visits at UC San Diego Health for an intervention visit with a study provider * consider incorporating recommended lifestyle modifications * complete weekly surveys

Steroid Injection for Chronic Cough

18+
All Sexes
Charleston, SC

The primary goal of this study is to test the hypothesis that injecting steroid intramuscularly is an effective treatment for unexplained chronic cough. This will be achieved through the design of a prospective, placebo-controlled, single-blind, randomized clinical trial in which one group of patients will undergo a steroid injection into the deltoid muscle and the second group will undergo a placebo injection into the deltoid muscle. Data to determine if a clinically significant difference exists between the outcomes of the two groups will be measured by a dichotomous yes/no response to improvement, the Leicester Cough Questionnaire, and a visual analogue scale for symptom severity. This will provide the answer to the general question of whether or not the intramuscular injections are clinically effective for patients with unexplained chronic cough. Furthermore, any adverse reactions will be thoroughly documented. If this hypothesized treatment is proven effective, this can greatly improve the care of chronic cough patients by allowing for an evidence-based treatment option and a treatment option that may improve access to care. While the superior laryngeal nerve (SLN) injection is typically performed by fellowship trained laryngologists, intramuscular injections could be more widely utilized by general otolaryngologists or providers in other fields of medicine.
