Trimix is a combination of three drugs: alprostadil, papaverine, and phentolamine. These medications work in combination to increase blood flow to the penis, resulting in an erection. [1] [2] [3] Alprostadil is a prostaglandin vasodilator that allows more blood to flow into the area by relaxing the smooth muscle in the blood vessels of the penis.
Prostanoids, including alprostadil, do not reduce the risk of limb amputation but may offer a slight improvement in rest-pain and leg ulcer healing in persons with critical limb ischemia. [ 23 ] Preventative administration of alprostadil may reduce the risk of kidney injury (specifically contrast-induced nephropathy) in persons having cardiac ...
Ivermectin is an antiparasitic drug. [7] After its discovery in 1975, [8] its first uses were in veterinary medicine to prevent and treat heartworm and acariasis. [9] Approved for human use in 1987, [10] it is used to treat infestations including head lice, scabies, river blindness (onchocerciasis), strongyloidiasis, trichuriasis, ascariasis and lymphatic filariasis.

In humans, electroejaculation is usually carried out under a general anesthetic. [1] An electric probe is inserted into the rectum adjacent to the prostate gland . The probe delivers an AC voltage, usually 12–24 volts sine wave at a frequency of 60 Hz, with a current limited to usually 500 mA, although some devices can generate currents of up ...
Plants, animals, and humans can all be affected by high cobalt concentrations in the environment. For plants, the uptake and distribution of cobalt is entirely species-specific. [ 8 ] In some species of plants, the overaccumulation of cobalt can lead to an iron deficiency .
