Clinical Trials Related to Morphine
Efficacy and Safety of Intranasal Morphine for Pain After Third Molar Extraction [Completed]
This study involves approximately 200 patients designed to evaluate the efficacy and safety
of intranasal (IN) morphine 7. 5 mg and 15 mg, intravenous morphine (IV) 7. 5 mg, immediate
release oral (PO) morphine 60 mg or placebo in patients with acute postsurgical pain
following third molar extraction.
Intrathecal Morphine in Knee Arthroplasty [Completed]
This study is designed to explore the efficacy lower doses of intra-spinal morphine for pain
relief and side effect profiles of same in the setting of Total Knee Replacement. We
hypothesized that a dose greater than that used in Total Hip Replacement was needed and
wished to find a dose which was effective but had a low side effect profile.
Efficacy and Safety of Intranasal Morphine for Pain After Bunion Surgery [Completed]
Study designed to evaluate the efficacy and safety of Intranasal (IN) Morphine Nasal Spray
(MNS075) 3. 75 mg, 7. 5 mg, 15 mg, and 30 mg, intravenous (IV) morphine 7. 5 mg, or IN placebo
in patients with moderate to severe post-surgical pain following orthopedic surgery. After
initial dosing, up to six (6) doses of IN MNS075 7. 5 mg or 15 mg for up to twenty-four (24)
hours will be evaluated. The rescue dose remained the same for each.
INFUSE Morphine Study [Completed]
Double-blind study comparing the pharmacokinetics, safety and tolerability of morphine
administered subcutaneously (SC) with and without human recombinant hyaluronidase (HYLENEX)
and intravenously conducted in patients in a hospice care setting or through a palliative
care medicine setting. In this within-patient controlled study, each eligible study patient
receives a single injection by each of the three methods of morphine administration,
sequentially on three consecutive days, according to the order specified by a randomization
Each of the three injections consists of 5 mg of morphine (1. 0 mL of 5 mg/mL solution). The
HYLENEX injection will be 1 mL of 150 units. Although the IV administration will not be
blinded, the two SC injections will be double-blinded, using the same volume of normal saline
(0. 9% sodium chloride) placebo (1. 0 mL) as HYLENEX.
Problems With Morphine Use in Patients With a Severe Brain Injury [Active, not recruiting]
Hypothesis: During severe brain trauma (injury, surgery) the ensuing inflammatory response in
the central nervous system (CNS) results in a decrease in the expression of the transporter
protein p-glycoprotein (PGP) in the blood brain barrier. This loss results in the
penetration into the brain of certain drugs that are normally excluded by the transporter
protein. In this study the working hypothesis is that the agitation observed in patients
with CNS trauma treated with morphine is related to the inflammation evoked loss of PGP in
the blood brain barrier and the accumulation of the morphine metabolite 3-morphine
