The administration and the induction of systemic effects of the drugs under research were done by oral route. The suspension dosage form is suitable for the products that are physically and chemically stable. 5 and 6 Suspensions can provide high drug concentration through a relatively simple preparation procedure. In this study, oral formulations containing
therapeutically active extracts of these drugs Dinaciclib chemical structure were developed in the form of suspensions. The suitability of the formulation was determined by considering the solubility of the extracts in water or Tween-80. Based on the results, polyherbal oral suspensions of the extracts were prepared in varying combinations/ratios. In this study, the authors attempted to formulate three novel herbal oral male contraceptive suspensions (HOCS-M), namely, HOCS-M-I, HOCS-M-II, and HOCS-M-III, consisting of therapeutically active extracts of the three plants in varying combinations/ratios.
These were prepared together with a suitable suspending agents and stabilizers and evaluated pharmaceutically. Methanol (70% v/v) extracts of C. aphylla aerial part (MECA), C. papaya leaves (MECP) and F. limonia fruit (MEFL) were used in this study. Oral suspensions that contained extract of plants showing potential male antifertility activity were prepared by the trituration method using a suitable suspending agent and other excipients. Selleck ABT-888 4 The amount of individual plant required for the formulation HOCS-M was calculated based on the therapeutically effective dose (dose at which plant showed maximum activity) of that plant. That is, the maximum effective dose of individual plants was found to be 300 mg/kg for MECA, 500 mg/kg for MEFL and 300 mg/kg for MECP. Thus, the average effective dose of combined extracts is calculated by dividing sum of maximum effective doses individual plant by number of plants. Therefore, the content of individual plant required for formulating HOCS-M were calculated from
the average effective dose of the combined extracts by ratio proportion method. More over the authors Tryptophan synthase developed three pharmaceutically stable oral suspensions containing contraceptive principles with convincing quality control parameters. These suspensions are: 1) HOCS-M-I comprises of a combination of therapeutically effective extracts of the aerial parts of C. aphylla and leaves of C. papaya. Therefore, the present study was taken to assess the comparative contraceptive/antifertility activity of individual suspensions for their effective contraceptive efficacy in mature male rats. The effect of formulations HOCS-M-I, HOCS-M-II and HOCS-M-III on spermatogenesis of sexually mature male rats were determined by studying the following parameters: a) Normal and abnormal sperm, sperm count, sperm motility of treated rat. In addition, recovery study was also carried out.
