Summary of "Comparative efficacy and acceptability of first-line drugs for the acute treatment of generalized anxiety disorder in adults: A network meta-analysis."

The guide recommends SSRI and SNRI drugs as first-line treatments for generalized anxiety disorder (GAD). Therefore, we aimed to update the evidence using network meta-analysis by comparing the efficacy and acceptability of first-line drugs. The relevant electronic databases were searched for placebo-controlled and head-to-head trials of 11 drugs used for the acute treatment of adults with GAD from 1980 up to January 1, 2019. Data on demographics, clinical, and treatment information were extracted from each eligible study. The primary outcomes were efficacy (quantified as the change in the total score on the Hamilton Anxiety Scale from baseline) and acceptability (quantified as treatment discontinuations due to any cause). Overall, the data on 41 RCTs were sufficient or appropriate for inclusion. In terms of efficacy, all of the drugs except fluoxetine and vortioxetine were more effective than placebo, with the weighted mean difference of the Hamilton Anxiety Scale score ranging between -3.2 (95% credible interval [CrI] = -4.2 to -2.2) for escitalopram and -1·8 (95% CrI = -3.1 to -0.55) for vilazodone. For acceptability, only vilazodone (OR = 1.7, 95% CrI = 1.1 to 2.7) were worse than placebo, others did not show significant differences from placebo. In head-to-head comparisons, vortioxetine showed better acceptability and tolerability but worse efficacy and response rate. In conclusion, most drugs are more effective than placebo, and there are few significant differences between the active drugs and placebo on acceptability. Overall, duloxetine and escitalopram showed better efficacy while vortioxetine showed better acceptability.

Medical and Biotech [MESH] Definitions

Drugs used in the treatment of tuberculosis. They are divided into two main classes: "first-line" agents, those with the greatest efficacy and acceptable degrees of toxicity used successfully in the great majority of cases; and "second-line" drugs used in drug-resistant cases or those in which some other patient-related condition has compromised the effectiveness of primary therapy.

Tuberculosis resistant to chemotherapy with two or more ANTITUBERCULAR AGENTS, including at least ISONIAZID and RIFAMPICIN. The problem of resistance is particularly troublesome in tuberculous OPPORTUNISTIC INFECTIONS associated with HIV INFECTIONS. It requires the use of second line drugs which are more toxic than the first line regimens. TB with isolates that have developed further resistance to at least three of the six classes of second line drugs is defined as EXTENSIVELY DRUG-RESISTANT TUBERCULOSIS.

Drugs which have received FDA approval for human testing but have yet to be approved for commercial marketing. This includes drugs used for treatment while they still are undergoing clinical trials (Treatment IND). The main heading includes drugs under investigation in foreign countries.

The relative equivalency in the efficacy of different modes of treatment of a disease, most often used to compare the efficacy of different pharmaceuticals to treat a given disease.

Drugs manufactured and sold with the intent to misrepresent its origin, authenticity, chemical composition, and or efficacy. Counterfeit drugs may contain inappropriate quantities of ingredients not listed on the label or package. In order to further deceive the consumer, the packaging, container, or labeling, may be inaccurate, incorrect, or fake.
