Promethazine

Conclusion: We found high-certainty evidence that five single drugs (aprepitant, ramosetron, granisetron, dexamethasone, and ondansetron) reduce vomiting, and moderate-certainty evidence that two other single drugs (fosaprepitant and droperidol) probably reduce vomiting, compared to placebo. Four of the six substance classes (5-HT₃ receptor antagonists, D₂ receptor antagonists, NK₁ receptor antagonists, and corticosteroids) were thus represented by at least one drug with important benefit for prevention of vomiting. Combinations of drugs were generally more effective than the corresponding single drugs in

Conclusion: This umbrella review offers a comprehensive overview of the pharmacological management of psychomotor agitation in patients with psychiatric disorders. Among the most frequently used medications in the reviewed studies were haloperidol, olanzapine, and lorazepam. The findings underscore the importance of tailored treatment approaches and the need for further research to refine the management of psychomotor agitation in psychiatric settings.

Conclusion: Within a minimally contextualized framework, as single agents, intravenous tropisetron and intravenous prochlorperazine are definitely among the most effective, intravenous metoclopramide and intravenous droperidol are possibly among the most effective, and oral ondansetron is definitely among the least effective; considering certain adverse reactions, intravenous metoclopramide, intravenous droperidol, and intravenous promethazine are definitely among the most harmful.

Conclusion: For mild symptoms of nausea and emesis of pregnancy, ginger, pyridoxine, antihistamines, and metoclopramide were associated with greater benefit than placebo. For moderate symptoms, pyridoxine-doxylamine, promethazine, and metoclopramide were associated with greater benefit than placebo. Ondansetron was associated with improvement for a range of symptom severity. Corticosteroids may be associated with benefit in severe cases. Overall the quality of evidence was low.
