Karwinskia humboldtiana (buckthorn) fruit causes central nervous system damage during chronic intoxication in the rat.

Karwinskia humboldtiana fruit (Kh) causes a neurological disorder 3-4 weeks after ingestion, characterized by flaccid, symmetrical, ascending paralysis, similar to the Guillain-Barre syndrome. In this polyneuropathy the lesion (demyelization) in peripheral nerves has been described in several animal species, both in acute and in chronic intoxication. However, no reports exist about the presence of lesions in the Central Nervous System (CNS), in chronic intoxication.

Bioequivalence of single 100-mg doses of two oral formulations of topiramate: an open-label, randomized-sequence, two-period crossover study in healthy adult male Mexican volunteers.

Background: The proprietary form of topiramate is indicated in Mexico as an antiepileptic agent and in the prophylaxis of migraine headaches. However, before generic topiramate is placed on the market, pharmacokinetic studies investigating the bioequivalence of generic and branded formulations are needed.

Objective: The aim of this study was to compare the bioequivalence and tolerability of a generic (test) and a branded (reference) formulation of topiramate 100 mg in healthy Mexican volunteers.

Evaluation of the bioequivalence of single 100-mg doses of two oral formulations of cyclosporin A microemulsion: a randomized, open-label, two-period crossover study in healthy adult male Mexican volunteers.

Background: Cyclosporin A is widely used in Mexico as immunosuppressive therapy in organ transplantation and in the treatment of autoimmune disorders. Although several generic oral formulations of cyclosporin A are available in Mexico, information concerning the bioequivalence of these formulations in the Mexican population is not available in the published literature.

Objective: The aim of this study was to compare the bioequivalence and tolerability of a generic (test) and a branded (reference) soft-gelatin capsule formulation of cyclosporin A microemulsion 100 mg available in Mexico.

An experimental model of peripheral neuropathy induced in rats by Karwinskia humboldtiana (buckthorn) fruit.

Intoxication by Karwinskia humboldtiana (buckthorn) fruit presents a neurological picture similar to that of Guillain-Barré syndrome. In this report, we describe an experimental animal model of peripheral neuropathy induced by buckthorn fruit. Four groups of Wistar rats received one oral dose of 1.

Bioavailability of two oral formulations of loratadine 20 mg with concomitant ketoconazole: an open-label, randomized, two-period crossover comparison in healthy Mexican adult volunteers.

Background: Loratadine is a long-acting antihistamine with selective peripheral histamine H(1)-receptor antagonistic activity and fewer sedative effects compared with conventional antihistamines, and is widely used in Mexico. Although several generic formulations of loratadine are available in Mexico, based on a literature search, information concerning the bioavailability of each formulation in the Mexican population is not available.

Objective: The aim of this study was to compare the bioavailability and tolerability of 2 oral formulations of loratadine 20 mg (two 10-mg tablets) used in Mexico: Sensibit (test formulation; Laboratorios Liomont S.
