Drug Name Protonix

Death is caused by paralysis of respiratory muscles. Injected intramuscularly at minuscule dosage, botulinum toxin type A is used to treat blepharospasm, strabismus, achalasia of the lower esophageal sphincter, and spastic aphonia. A pathological rise in serum Mg2+ levels also causes inhibition of ACh release, hence inhibition of neuromuscular transmission.
Interactions. Antacids inhibit iron absorption. Combination with ascorbic acid (Vitamin C), for protecting Fe2+ from oxidation to Fe3+, is theoretically sound, but practically is not needed. Parenteral administration of Fe3+ salts is indicated only when adequate oral replacement is not possible. There is a risk of overdosage with iron deposition in tissues (hemosiderosis).

 

Unlike inhalational agents, most of these drugs affect consciousness only and are devoid of analgesic activity (exception: ketamine). The effect cannot be ascribed to nonselective binding to neuronal cell membranes, although this may hold for propofol. Most injectable anesthetics are characterized by a short duration of action.
Local anesthetics are capable of inhibiting this rapid inward flux of Na+; initiation and propagation of excitation are therefore blocked (A). Most local anesthetics exist in part in the cationic amphiphilic form (cf. p. 208). This physicochemical property favors incorporation into membrane interphases, boundary regions between polar and apolar domains.
