It has no effect on bacteria or on other genera of fungi. Human Pharmacology Following oral administration, griseofulvin is deposited in the keratin precursor cells and has a greater affinity for diseased tissue. The drug is tightly bound to the new keratin which becomes highly resistant to fungal invasions. The efficiency of gastrointestinal absorption of ultramicrocrystalline griseofulvin is approximately one and one-half times that of the conventional microsize griseofulvin. This factor permits the oral intake of two-thirds as much ultramicrocrystalline griseofulvin as the microsize form. However, there is currently no evidence that this lower dose confers any significant clinical differences with regard to safety and/or efficacy.

Venlafaxine Hydrochloride Extended-Release Tablets are extended-release tablets for oral administration that contain venlafaxine hydrochloride, a structurally novel antidepressant. Venlafaxine hydrochloride is a selective serotonin and norepinephrine reuptake inhibitor (SNRI).

Venlafaxine hydrochloride is a white to off-white crystalline solid with a solubility of 572 mg/mL in water (adjusted to ionic strength of 0.2 M with sodium chloride). Its octanol:water (0.2 M sodium chloride) partition coefficient is 0.43. Venlafaxine Hydrochloride Extended-Release Tablets are formulated as extended-release tablet for once-a-day oral administration. Venlafaxine Hydrochloride Extended-Release Tablets use matrix core and extended-release coating to deliver venlafaxine hydrochloride at a controlled rate over approximately 24 hours. The unitary tablet core is composed of the drug and excipients (including the matrix forming components). In an aqueous environment, such as the gastrointestinal tract, water permeates slowly through the coating into the tablet core, causing the hydrophilic matrix polymer to expand and to form a gel layer on the surface of the tablet. This gel acts as a barrier to the drug release, the drug is dissolved and is released by slow diffusion and erosion of the gel. The extended-release coating layer controls the rate at which water permeates into the tablet core, which in turn controls also the rate of drug delivery. The controlled rate of drug delivery into the gastrointestinal lumen is thus independent of pH or gastrointestinal motility. Tablets contain venlafaxine hydrochloride equivalent to 225 mg venlafaxine. Inactive ingredients consist of dibasic calcium phosphate dihydrate, hypromellose, methacrylic acid copolymer, colloidal silicon dioxide, magnesium stearate, polyvinyl acetate dispersion, talc, polyethylene glycol, polyvinyl alcohol, povidone, triethyl citrate, macrogol stearyl ether, sodium lauryl sulfate, carnauba wax, titanium dioxide, propylene glycol and FD&C blue #1. velafaxine-structure

System Components and Performance: Verapamil Hydrochloride Extended-release Capsules (PM) uses the proprietary CODAS ® (Chronotherapeutic Oral Drug Absorption System) technology, which is designed for bedtime dosing, incorporating a 4 to 5-hour delay in drug delivery. The controlled-onset delivery system results in a maximum plasma concentration (C max ) of verapamil in the morning hours. These pellet filled capsules provide for extended-release of the drug in the gastrointestinal tract. The Verapamil Hydrochloride Extended-release Capsules (PM) formulation has been designed to initiate the release of verapamil 4-5 hours after ingestion. This delay is introduced by the level of non-enteric release-controlling polymer applied to drug loaded beads. The release-controlling polymer is a combination of water soluble and water insoluble polymers. As water from the gastrointestinal tract comes into contact with the polymer coated beads, the water soluble polymer slowly dissolves and the drug diffuses through the resulting pores in the coating. The water insoluble polymer continues to act as a barrier, maintaining the controlled release of the drug. The rate of release is essentially independent of pH, posture and food. Multiparticulate systems such as Verapamil Hydrochloride Extended-release Capsules (PM) have been shown to be independent of gastrointestinal motility. image description
