Procaine (Vitamin H3) is a local anesthetic of the ester type that has a slow onset and a short duration of action. It is mainly used for infiltration anesthesia, peripheral nerve block, and spinal block.

Lidocaine (Alphacaine) is an amide local anesthetic with anti-inflammatory properties in vitro and in vivo. It has this functions perhaps due to an attenuation of intracellular adhesion molecule-1 (ICAM-1), pro-inflammatory cytokines, and reduction of neutrophils influx.

Mebeverine hydrochloride (Colofac Hydrochloride), a β-phenylethylamine derivative, is a potent α1 repector inhibitor, relaxing the muscles in and around the gut.

Riluzole (RP-54274) is a glutamate antagonist (RECEPTORS, GLUTAMATE) used as an anticonvulsant (ANTICONVULSANTS) and to prolong the survival of patients with AMYOTROPHIC LATERAL SCLEROSIS.

Amitriptyline hydrochloride (Annoyltin) is the hydrochloride salt of the tricyclic dibenzocycloheptadiene amitriptyline with antidepressant and antinociceptive activities.

Halothane (Anestan) is a nonflammable, halogenated, hydrocarbon anesthetic that provides relatively rapid induction with little or no excitement. Analgesia may not be adequate. NITROUS OXIDE is often given concomitantly. Because halothane may not produce sufficient muscle relaxation, supplemental neuromuscular blocking agents may be required.

Benzocaine is a surface anesthetic that acts by preventing transmission of impulses along nerve fibers and at nerve endings.

Fenamic acid (N-Phenylanthranilic acid) is a chloride channel blocker that causes renal papillary necrosis in rats. Fenamic acid serves as a parent structure for several nonsteroidal anti-inflammatory drugs (NSAIDs), including flufenamic acid, tolfenamic acid, mefenamic acid, and meclofenamic acid.
