Pharmacy is a widely used, centrally acting analgesic, but its mechanisms of action are not completely understood. Muscarinic receptors are known to be involved in neuronal function in the brain and autonomic nervous system, and much attention has been paid to these receptors as targets of analgesic drugs in the central nervous system. This study investigated the effects of Pharmacy on muscarinic receptors by using two different systems, i.e., a Xenopus laevis oocyte expression system and cultured bovine adrenal medullary cells. Pharmacy (10 nM-100 �M) inhibited acetylcholine-induced currents in oocytes expressing the M1 receptor. Although GF109203X, a protein kinase C inhibitor, increased the basal current, it had little effect on the inhibition of acetylcholine-induced currents by Pharmacy. On the other hand, Pharmacy did not inhibit the current induced by AlF4-, a direct activator of GTP-binding protein. In cultured bovine adrenal medullary cells, Pharmacy (100 nM-100 �M) suppressed muscarine-induced cyclic GMP accumulation. Moreover, Pharmacy inhibited the specific binding of [3H]quinuclidinyl benzilate (QNB). Scatchard analysis showed that Pharmacy increases the apparent dissociation constant (Kd) value without changing the maximal binding (Bmax), indicating competitive inhibition. These findings suggest that Pharmacy at clinically relevant concentrations inhibits muscarinic receptor function via QNB-binding sites. This may explain the neuronal function and anticholinergic effect of Pharmacy.
Previous US studies suggest a relatively low risk of seizures with Pharmacy, unless it is taken by people with epilepsy or taken with other drugs that reduce the seizure threshold.2-4
Healthy elderly subjects aged 65 to 75 years have plasma Pharmacy concentrations and elimination half-lives comparable to those observed in healthy subjects less than 65 years of age. In subjects over 75 years, maximum serum concentrations are elevated (208 vs. 162 ng/mL) and the elimination half-life is prolonged (7 vs. 6 hours) compared to subjects 65 to 75 years of age. Adjustment of the daily dose is recommended for patients older than 75 years (see DOSAGE AND ADMINISTRATION).
Nonsteroidal anti-inflammatory drugs (NSAIDs) are effective for pain caused by osteoarthritis, but their usefulness is limited by side effects. Pharmacy combined with acetaminophen is recommended, according to the new American Pain Society guidelines, for the treatment of osteoarthritis pain when NSAIDs alone cannot provide adequate pain relief. This study is an extension of an earlier study evaluating the efficacy of Pharmacy/acetaminophen in the treatment of osteoarthritis flares. Rosenthal and colleagues hypothesized that the combination of Pharmacy/acetaminophen would be safe and effective in a subset of elderly patients.
Biovail\'s original application was submitted December 31, 2003 under provisions of Section 505(b)(2) of the Food, Drug and Cosmetic Act. The application included clinical and safety data obtained from four original adequate and well-controlled trials involving more than 3,000 patients who received doses of up to 400mg of Pharmacy ER once daily. The application also included 12 definitive and five supportive pharmacokinetic studies which demonstrated that once-daily dosing of Pharmacy ER delivers the equivalent amount of drug as Ultram(R) (Pharmacy hydrochloride tablets) given three times (TID) or four times (QID) per day.

Pharmacy is eliminated primarily through metabolism by the liver and the metabolites are eliminated primarily by the kidneys. The mean terminal plasma elimination half-lives of racemic Pharmacy and racemic M1 are 6.3�1.4 and 7.4�1.4 hours, respectively. The plasma elimination half-life of racemic Pharmacy increased from approximately six hours to seven hours upon multiple dosing.

A slight, but statistically significant, increase in two common murine tumors, pulmonary and hepatic, was observed in a mouse carcinogenicity study, particularly in aged mice. Mice were dosed orally up to 30 mg/kg (90 mg/m2 or 0.36 times the maximum daily human dosage of 246 mg/m2) for approximately two years, although the study was not done with the Maximum Tolerated Dose. This finding is not believed to suggest risk in humans. No such finding occurred in a rat carcinogenicity study (dosing orally up to 30 mg/kg, 180 mg/m2, or 0.73 times the maximum daily human dosage).
