New dissolving paracetamol tablet put to the test

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Exclusion Criteria: * Safety Concerns 1. Existing cardiac and/or haematological diseases or pathological findings, which might interfere with the safety or tolerability of the active ingredient. 2. Existing renal diseases or pathological findings, which might interfere with the safety or tolerability, and/or pharmacokinetics of the active ingredient. 3. Current evidence of ongoing hepatic disease or impaired hepatic function at screening. A participant will be excluded if more than one of the following lab value deviations are found: 1) Aspartate aminotransferase (AST) (\>= 1.2 upper limit of normal \[ULN\]), Alanine transaminase (ALT) (\>= 1.2 ULN), 2) Gamma-glutamyl transferase (GGT) (\>= 1.2 ULN), Alkaline phosphatase (ALP) (\>= 1.2 ULN), 3) total bilirubin (greater than \[\>\] 2.00 milligrams per deciliter (mg/dL), except in case of existing Morbus Gilbert-Meulengracht deduced from anamnesis/medical history) or creatine kinase (\>= 3 ULN), and creatinine \> 0.1 mg/dL ULN (limit of \> 0.1 mg/dL correspondents to of \> 9 micromole per liter \[μmol/l\] ULN). A single deviation from the above values is acceptable and will not exclude the candidate, unless specifically advised by the investigator. 4. Existing gastrointestinal diseases or pathological findings, which might interfere with the safety, tolerability, absorption and/or pharmacokinetics of the active ingredient. 5. History of relevant central nervous system (CNS) and/or psychiatric disorders and/or currently treated CNS and/or psychiatric disorders. 6. History or clinical evidence at screening of pancreatic injury or pancreatitis. 7. History of inflammatory bowel disease or gastrointestinal bleeding including peptic ulcers. 8.

Evidence of urinary obstruction (example, due to benign prostate hyperplasia) or difficulty in voiding at screening. 10. Status of glutathione depletion (eating disorder, cystic fibrosis, human immunodeficiency virus \[HIV\] infection, starvation, cachexia) due to metabolic deficiencies. 11. Oral surgery within 4 weeks of dosing, dental work or extractions within 2 weeks of dosing, or presence of any clinically significant (as determined by the principal investigator or designee) oral pathology including lesions, sores or inflammation. 12. History of major gastrointestinal tract surgery such as gastrectomy, gastroenterostomy, bowel resection, gastric bypass, gastric stapling or gastric banding (note: this is not applicable for minor abdominal surgery without significant tissue resection, example, appendectomy and herniorrhaphy). 13. Participants, who report a frequent occurrence of migraine attacks. 14. Acute or chronic diseases which may interfere with the pharmacokinetics of the investigational medicinal product (IMP). 15. Clinically relevant chronic or acute infectious illnesses or febrile infections within two weeks prior to start of the study. 16. History or current evidence of renal disease or impaired renal function at screening as indicated by abnormal levels of serum creatinine (\> 1.43 mg/dL) or blood urea nitrogen (BUN) (\>= 35 mg/dL) or the presence of clinically significant abnormal urinary constituents (example, albuminuria). 17. Systolic blood pressure less than (\<) 90 or \> 139 millimeter of mercury (mmHg). 18. Diastolic blood pressure \< 50 or \> 89 mmHg. 19. Heart rate \< 50 beats per minute (bpm) or \> 90 bpm. 20. Corrected QT interval (QTc) interval \> 450 milliseconds (ms) for men and \> 470 ms for women. 21. Hemoglobin value \< 12.0 grams per deciliter (g/dL) for males and \< 11.5 g/dL for females. 22. Evidence or history of medication overuse headache, or allergic disease to medication within the last 5 years that may increase the risk associated with study participation. 23. Laboratory values out of normal range unless the deviation from normal is judged as not relevant for the clinical trial by the investigator. 24. Positive anti-HIV-test (if positive to be verified by western blot), hepatitis B surface antigen (HBs-AG) test and anti-hepatitis B core immunoglobulin M (HBc IgM) or anti-hepatitis C virus (HCV) test. 25. Known allergic reactions to the active ingredients used or to constituents of the pharmaceutical preparations. 26. Any history of asthma, urticaria, or other significant allergic diathesis or allergic reaction to any other pain reliever/fever reducer. Participant with uncomplicated seasonal allergic rhinitis can be accepted if expected allergy season is clearly outside enrollment/treatment period. 27. History of severe allergies or multiple drug allergies unless it is judged as not relevant for the clinical trial by the investigator. * Lack of suitability for the clinical trial 1. History of illegal or legal drug abuse within 1 year prior to screening or recreational use of soft drugs (such as marijuana, codeine) within 1 month or hard drugs (such as cocaine, phencyclidine \[PCP\], crack, any opioid derivatives such as heroin or fentanyl, and amphetamine derivatives) within 3 months prior to screening. 2. Positive alcohol, cotinine or drug test at screening examination. 3. History of alcohol abuse in the last 5 years or regular intake of alcoholic food or beverages of \>= 24 gram (g) pure ethanol for men or \>= 12 g pure ethanol for women per day. 4.

Use of any systemic or topical medication (including over the counter \[OTC\] medications, herbal remedies, cannabidiol cosmetics and any anticholinergic medicines or other medicines that may cause dry mouth) within 2 weeks or within less than 10 times the elimination half-life of the respective drug (whichever is longer) before first scheduled study drug administration, or is anticipated to require any concomitant medication during that period or at any time throughout the study. 9. Any history of long-term treatment with carbamazepine, phenobarbitone, phenytoin, primidone, rifampicin, St John's Wort or other drugs that induce liver enzymes. 10.
