Ibuprofen liquigel for oral surgery pain.

BACKGROUND: Ibuprofen liquigel is a solubilized potassium ibuprofen 200-mg gelatin capsule formulation that was approved for over-the-counter use in 1995. OBJECTIVE: This study compared the analgesic efficacy and tolerability of ibuprofen liquigel 200 mg, ibuprofen liquigel 400 mg, acetaminophen caplets 1000 mg, and placebo in patients experiencing moderate or severe pain after surgical removal of impacted third molars. METHODS: This randomized, double-blind, parallel-group, 6-hour study was conducted in 210 patients experiencing moderate or severe postoperative pain. Ratings of pain intensity and pain relief were recorded every 15 minutes for the first hour, at 90 and 120 minutes, and then hourly through hour 6. The onsets of first perceptible relief and meaningful relief were recorded using 2 stopwatches. An analysis of variance model was employed to test for significant differences (P < or = 0.05) between treatment groups with respect to pain relief, pain intensity difference, total pain relief (TOTPAR), and summed pain intensity difference (SPID). Stopwatch measures were analyzed using the Cox proportional hazards model. Drug tolerability was assessed by monitoring the occurrence of adverse events. RESULTS: During the first 2 hours of the study (TOTPAR 2 and SPID 2), all active treatments were significantly more efficacious than placebo (P < 0.001), with ibuprofen liquigel 200 and 400 mg significantly more efficacious than acetaminophen 1000 mg (P < 0.05 and P < 0.01, respectively). For the entire duration of the study (TOTPAR 6 and SPID 6), only the 2 doses of ibuprofen liquigel were significantly more efficacious than placebo (P < 0.001). Ibuprofen liquigel 200 and 400 mg were also significantly more efficacious than acetaminophen 1000 mg on the summary measures TOTPAR 6 and SPID 6 (P < 0.01 and P < 0.001, respectively). Analysis of the stopwatch data revealed that all active treatments displayed significantly more rapid onsets to confirmed first perceptible relief (P < 0.001 to < 0.05) and meaningful relief (P < 0.001 to < 0.01) than did placebo, with ibuprofen liquigel 400 mg displaying a significantly more rapid onset to meaningful relief than acetaminophen 1000 mg (P < 0.05) and a significantly more rapid onset to confirmed first perceptible relief than acetaminophen 1000 mg (P < 0.001) and ibuprofen liquigel 200 mg (P < 0.01). All adverse events were considered mild or moderate, with an overall incidence of 11.5% in the ibuprofen liquigel 200-mg group, 6.8% in the ibuprofen liquigel 400-mg group, 19.0% in the acetaminophen 1000-mg group, and 25.9% in the placebo group. CONCLUSIONS: Ibuprofen liquigel provided greater peak and overall analgesic effects and a more rapid onset to analgesia than did acetaminophen 1000 mg.

Conventional and extended-release etodolac for postsurgical dental pain.

This double-masked, parallel-group, randomized study compared the analgesic efficacy and tolerability of a single investigational 1200-mg dose of extended-release etodolac with those of a single 400-mg dose of extended-release etodolac and twice-daily doses of conventional etodolac 200 and 400 mg and placebo given 8 hours apart in 237 patients with moderate or severe postoperative pain following surgical removal of > or = 2 impacted third molars. Both doses of conventional etodolac and the 1200-mg dose of extended-release etodolac were significantly more effective on all summary analgesic measures than placebo (P < 0.05). Conventional etodolac had an onset of analgesic activity within 45 (400 mg) to 60 (200 mg) minutes and an analgesic duration of 5 to 6 hours. Extended-release etodolac 1200 mg had an onset of action within 60 minutes and an analgesic duration of 12 to 24 hours. At hours 2 and 3, conventional etodolac 400 mg was significantly more effective than the other treatments; from hours 6 through 12, extended-release etodolac 1200 mg was significantly more effective than the other treatments (both, P < 0.05). No serious adverse events were observed in this study, with an incidence of side effects in the active etodolac groups no different than that with placebo. Extended-release etodolac 1200 mg has a prolonged analgesic duration and an acceptable side-effect profile in the oral surgery pain model.

A dose-ranging study of bromfenac sodium in oral surgery pain.

OBJECTIVE: The purpose of this study was to evaluate the analgesic efficacy and safety of five graded doses of bromfenac sodium in patients experiencing moderate to severe pain after the surgical removal of impacted third molar teeth. STUDY DESIGN: The study employed a randomized, double-blind, single-dose, 8-hour, inpatient evaluation period. The treatment groups included placebo (n = 21) and bromfenac (n = 102) at dosage strengths of 5 mg (n = 21), 25 mg (n = 20), 50 mg (n = 20), 100 mg (n = 20), and 200 mg (n = 21). Patients ingested a dose of study medication when their postsurgical pain reached a moderate or severe intensity. Pain intensity and pain relief were rated at 15, 30, 60, 90, and 120 minutes and then hourly for the remaining 6 hours. Efficacy and safety variables were analyzed by means of analysis of variance and chi-squared tests where appropriate. RESULTS: At all doses, bromfenac exhibited statistical superiority (p < 0.05) to placebo, with all but the 5-mg dose being significantly more efficacious for every summary analgesic measure (3- and 8-hour sum pain intensity difference and sum pain analog intensity difference, total pain relief, peak effects, sum of pain half gone, and global evaluation). Peak analgesic effects did not increase beyond those provided by the 25-mg dose of bromfenac, although both the 100- and 200-mg bromfenac doses provided a more rapid onset and a longer duration of analgesia than either the 25- or 50-mg dosage strengths. The most common side effects reported were headache, nausea, dizziness, and drowsiness; the incidence in the bromfenac group was no different from that in the placebo group. CONCLUSIONS: Bromfenac is a safe and efficacious analgesic, with a threshold dose of 5 mg and a positive dose-response up to 25 mg for peak effects and 100 mg for total analgesic activity.

Clinical considerations in the management of orbital blow-out fractures.

The management of orbital blow-out fractures has long been controversial. There are primarily two methods of treatment. One is a conservative approach that delays any kind of initial surgical intervention on the basis that most situations attributable to blow-out fractures resolve over time, obviating the need for surgery. On the other hand, initial aggressive surgical repair of blow-out fracture injuries is much more successful than secondary reconstructive procedures. This article discusses the advantages and disadvantages of both treatment methods.

Analgesic efficacy and safety of an intraoral lidocaine patch.

The effectiveness of intraoral II-docaine patches was tested by asking participants to rate the pain experienced after insertions of a 25-gauge needle. Needlesticks were performed at baseline and at various time points after patch placement. Each needlestick included contact with the periosteum. Lidocaine patches achieved significantly better analgesia than the placebo within 2.5 to five minutes after placement. Drug-related side effects were minimal and venous blood levels of lidocaine were low, averaging 10 to 14 times less than those achieved with a typical injection of lidocaine plus epinephrine. The authors conclude that the lidocaine patches used in this study are effective and safe in reducing needle insertion pain in adults.

Surgical management of a patient with cleidocranial dysplasia: a case report.

Cleidocranial dysplasia is associated with the formation of many supernumerary teeth which usually fail to erupt. In later life, cysts may form around the embedded teeth. The following report describes the management of such a case with a method which promotes satisfactory prosthodontic rehabilitation.
