These side effects may occur in as many as 90% of men treated with bicalutamide monotherapy, [29] but gynecomastia is generally reported to occur in 70 to 80% of patients. [30] In the EPC trial, at a median follow-up of 7.4 years, breast pain and gynecomastia respectively occurred in 73.6% and 68.8% of men treated with 150 mg/day bicalutamide ...
The drug itself reaches its peak plasma level after 1 hour and has also a half-life of 1 hour. Sibutramine is metabolized by cytochrome P450 isozyme CYP3A4 into two pharmacologically active primary and secondary amines (called active metabolites 1 and 2) with half-lives of 14 and 16 hours, respectively. Peak plasma concentrations of active ...
[2] [255] At 37 °C (98.6 °F), or normal human body temperature, bicalutamide is practically insoluble in water (4.6 mg/L), acid (4.6 mg/L at pH 1), and alkali (3.7 mg/L at pH 8). [ 27 ] [ 89 ] In organic solvents , it is slightly soluble in chloroform and absolute ethanol , sparingly soluble in methanol , and freely soluble in acetone and ...
Flunarizine is a selective calcium antagonist with moderate other actions including antihistamine, serotonin receptor blocking and dopamine D 2 blocking activity. Compared to other calcium channel blockers such as dihydropyridine derivatives, verapamil and diltiazem, flunarizine has low affinity to voltage-dependent calcium channels.
The side effects of penicillin are bodily responses to penicillin and closely related antibiotics that do not relate directly to its effect on bacteria. A side effect is an effect that is not intended with normal dosing. [1] Some of these reactions are visible and some occur in the body's organs or blood.
A 2010 Cochrane review found that men taking finasteride for BPH (with a mean age of 62.4) are at increased risk for impotence, erectile dysfunction (ED), decreased libido, and ejaculation disorder for the first year of treatment. The rates became indistinguishable from placebo after 2–4 years and these side effects usually got better over time.
However, it does act as a high affinity antagonist of the histamine H 1 receptor [24] and is a low to moderate affinity antagonist of the dopamine D 2, serotonin 5-HT 2, and α 1-adrenergic receptors. [3] [23] H 1 receptor antagonism accounts for its antihistamine effects and associated sedative side effects.
Dutasteride is approved for the treatment of male androgenetic alopecia in South Korea and Japan at a dosage of 0.5 mg per day. [6] [17] Several studies have found it to induce hair regrowth in men more rapidly and to a greater extent than even the highest approved dosage of finasteride.
